Description:
CARD SUBSTRATE LAMINATING DEVICE

BACKGROUND

[0001] Credentials include identification cards, driver's licenses, passports, and other documents. Such credentials are formed from credential or card substrates including paper substrates, plastic substrates, cards, and other materials. Such credentials generally include printed information, such as a photo, account numbers, identification numbers, and other personal information. Credentials can also include data that is encoded in a smartcard chip, a magnetic stripe, or a barcode, for example.

[0002] Credential production devices process credential substrates by performing at least one processing step in forming a final credential product. A card substrate laminating device performs a transfer or laminating process using a transfer ribbon. The transfer ribbon generally includes a continuous web liner or carrier layer to which a transfer layer is removably attached. The card substrate laminating device bonds the transfer layer to a surface of a card substrate using a heated roller.

[0003] The transfer layer may generally be one of two types: a patch laminate, or a fracturable thin film laminate. The patch laminate generally includes a pre-cut polyester film that has been coated with a thermal adhesive on one side. The pre-cut patch is attached to the liner with the thermal adhesive side exposed and available for lamination to the substrate. The heated roller is used to heat the patch to activate the adhesive, and press the patch to a surface of the card substrate to bond the patch onto the surface. The carrier layer is then removed from the bonded patch to complete the lamination process.

[0004] Fracturable thin film laminates are generally continuous resinous materials that have been coated onto the carrier layer. The side of the thin film laminate that is not attached to the carrier layer is generally coated with a thermal adhesive, which is used to create a bond between the thin film laminate and the surface of the card substrate. The heated roller of the laminating device is used to activate the adhesive and press the thin film laminate against the surface of the substrate to bond the thin film laminate to the surface. The removal of the carrier layer from the bonded thin film laminate completes the lamination process. The thin film laminate provides protection to the surface of the card. [0005] The transfer layer may also operate as a print intermediate, on which an image may be printed in a reverse-image printing process. In the reverse-image printing process, an image is printed to the exposed side of the transfer layer (i.e., patch laminate or thin film laminate). Next, the image on the transfer layer is registered with the card substrate. The heated roller is used to activate the adhesive on the imaged transfer layer causing the imaged transfer layer to bond to the surface of the card substrate. The carrier layer of the transfer ribbon is removed from the bonded imaged transfer layer to complete the transfer of the image to the card substrate. The transfer layer provides protection to the image and the surface of the card substrate.

[0006] Heated rollers of conventional card substrate laminating devices have a relatively large circumference relative to the size of the surface of a card substrate, which is conventionally 3.375 inches long by 2.125 inches wide. For example, typical card laminating devices use a heated roller having a circumference of greater than approximately 2.0 inches. As a result, a conventional lamination operation may be performed by the heated roller on a card substrate, which is fed past the heated roller with the short edge leading, by rotating the heated roller less than two times.

[0007] Conventional card laminating devices have utilized such large heating rollers because those of ordinary skill in the art believed a high heat capacity roller (e.g., 21 J/°C per inch of roller length) was necessary to perform satisfactory transfer lamination operations on card substrates, since such rollers would be capable of maintaining a near continuous transfer of heat to the transfer layer during the lamination operation, thereby ensuring uniform heating of the transfer layer. Additionally, the high heat capacity ensures that the temperature of the large heated roller would not change significantly during a transfer lamination operation. This allows the large heated roller to maintain a desired temperature during the performance of multiple lamination operations.

[0008] Downsides with the use of the large heated roller are evident during the initial startup of the device, and when it is necessary to process a single card substrate. For example, laminating devices using the large heated roller generally require a long warm-up time before the first card lamination operation can be performed due to the high heat capacity of the large heated roller. Thus, a user may experience significant delays before processing a single card substrate. Additionally, a large amount of energy must be used to initially heat the roller to an operating temperature at which it is capable of performing a card lamination operation, due to its high heat capacity. When only a single card is to be processed, the energy efficiency of the card lamination operation can be quite low.

[0027] FIG. 1 is a simplified side view of a system 100 in accordance with embodiments of the invention. In some embodiments, the system 100 includes a card substrate laminating device 102 formed in accordance with one or more embodiments described herein. The device 102 is configured to apply a transfer layer in the form of a thin film laminate or a patch laminate from a transfer ribbon 104 to a surface 106 of a card substrate 108. In some embodiments, the transfer ribbon 104 is supported between a supply spool 110 and a take-up spool 112.

[0028] In some embodiments, the system 100 includes a printing device 114 that is configured to facilitate forming an image on the card substrate 108. In some embodiments, the printing device 114 is configured to directly print an image to the surface 106 of the card substrate 108. In some embodiments, the printing device 114 is configured to print an image to the transfer layer of the transfer ribbon 104, as shown in FIG. 1. The imaged portion of the transfer layer is then transferred to the card substrate 108 by the laminating device 102 to form the image on the card substrate 108.

[0029] In some embodiments, the system 100 includes a controller 116, which includes one or more processors. The processors of the controller 116 are configured to execute program instructions, which are stored in local memory of the system 100 or other location, to control components of the device 100 and perform method steps and functions described herein. For instance, the controller 116 controls motors (not shown) that are used to drive the feeding of the transfer ribbon 104 between the supply spool 110 and the take-up spool 112, the feeding of the substrates 108, the feeding of a print ribbon, movement of components of the laminating device 102, and/or movement of components of the printing device 114. The controller 116 also controls the activation of components of the laminating device 102 and the printing device 114.

[0030] FIG. 2 is a simplified side cross-sectional view of a transfer ribbon 104 that includes a transfer layer 120 in the form of a thin film laminate or patch laminate, in accordance with exemplary embodiments of the invention. In some embodiments, the transfer layer 120 is attached to a backing or carrier layer 122. In some embodiments, the transfer layer 120 includes a thermal adhesive layer 124, which is activated during a transfer lamination process to bond the transfer layer 120 to a card substrate 108. The transfer ribbon 104 may also include a release layer 126 that assists in releasing the transfer layer 120 from the carrier layer 122 during a transfer lamination process. In some embodiments, such as when the system 100 includes the printing device 114, the transfer layer 120 includes an image receptive surface 128 that is configured to receive a printed image from the printing device 114. Other conventional materials or layers may also be included in the transfer layer 120.

[0031] In some embodiments, the transfer layer 120 includes a protective layer 130 located between the adhesive layer 124 and the carrier layer 122. The protective layer 130 operates to provide protection to the surface of the card substrate 108, to which the transfer layer 120 is laminated. In some embodiments, the protective layer 130 may also protect an image printed on the image receptive surface 128. When the transfer layer 120 is in the form of a patch laminate, the protective layer 130 may be a polyester film, for example. When the transfer layer 120 is in the form of a thin film laminate, the protective layer 130 may be a resinous material.

[0032] In some embodiments, the printing device 114 includes a print head 132 that is configured to print an image to the surface 106 of the card substrate 108, or to the transfer ribbon 104, such as to the image receptive surface 128 of the transfer layer 120. In some embodiments, the transfer ribbon 104 is supported between the print head 132 and a platen 134, as shown in FIG. 1. In some embodiments, after printing an image to the transfer layer 120 using the print head 132, the imaged portion of the transfer layer 120 is laminated to the surface 106 of the card substrate 108 using the laminating device 102.

[0033] In some embodiments, the print head 132 is an inkjet print head. In some embodiments, the print head 132 is a thermal print head that is configured to transfer print material from a print ribbon 136 to the surface 106 of the card substrate 108, or to the surface 128 of the transfer layer 120 (FIG. 1) to form an image thereon, in accordance with conventional techniques. In some embodiments, the print ribbon 136 is supported between a supply spool 138 and a take-up spool 140, as shown in FIG. 1. In some embodiments, the print ribbon 136 includes a plurality of print panels, such as colored dye panels, a black resin panel, and/or other conventional print ribbon print panels.

[0034] Some embodiments of the laminating device 102 will be described with reference to FIGS. 3-6. FIG. 3 is a simplified side view of the laminating device 102 in accordance with embodiments of the invention. FIGS. 4 and 5 are simplified top views of the laminating device 102 in accordance with embodiments of the invention. FIG. 6 is a simplified side view of the laminating device 102 of FIG. 5 in accordance with embodiments of the invention.

[0035] In some embodiments, the laminating device 102 includes a laminating or transfer roller 150 that includes an internal heating element 152 (FIG. 3), which is configured to heat the transfer roller 150. In some embodiments, the internal heating element 152 is a resistive heating element. In some embodiments, the transfer roller 150 includes a compliant exterior surface 153, such as a silicone rubber coating or layer, as shown in FIG. 3. In some embodiments, the silicone rubber coating is approximately 0.020 inches thick.

[0036] In some embodiments, the device 102 includes a substrate supply 154, from which individual card substrates 108 are fed along a processing path 156 past the transfer roller 150 using a transport mechanism 158. In some embodiments, the transport mechanism 158 comprises one or more motorized feed rollers 160, or other suitable mechanism for feeding the substrates 108. Embodiments of the laminating device 102 include sensors (not shown) that may be used to assist the controller 116 in the feeding of the substrates 108 along the processing path 156 with the transport mechanism 158, and aligning the substrates 108 with a transfer section of the transfer layer 120 that is to be laminated to the surface 106 of the substrate 108.

[0037] In some embodiments, the transfer ribbon 104 and the substrate 108 are fed between the transfer roller 150 and a platen 164, as shown in FIGS. 3 and 6. As the substrate 108 and the transfer ribbon 104 are fed in a direction indicated by arrow 166 past the transfer roller 150, the heating element 152 heats the transfer roller 150, which heats the transfer ribbon 104 and presses the transfer ribbon 104 against the surface 106 of the card substrate 108. The heating of the transfer ribbon 104 generally activates the thermal adhesive of the transfer layer 120, which bonds the transfer layer 120 to the surface 106 of the card substrate 108. In some embodiments, the carrier layer 122 is pulled from the transfer layer 120 that is bonded to the substrate 108, at a peel-off roller or bar 167, or other suitable component, and is collected by the take-up spool 112. When the transfer layer 120 is in the form of a thin film laminate, the transfer layer 120 that was not placed in contact with the surface 106 of the card substrate 108 remains adhered to the carrier layer 122 following the lamination operation, as indicated in FIG. 3.

[0038] The completion of the lamination process leaves the substrate 108 with the transfer layer 120 bonded to the surface 106. An image printed either to the surface 128 of the transfer layer 120, or to the surface 106 of the card substrate 108 prior to the lamination process, is protected by the transfer layer 120.

[0039] In some embodiments, the card substrate 108 is a conventional card substrate, such as that used to form identification cards, membership cards, driver's licenses, credit and debit cards, and other similar products. In some embodiments, the card substrate 108 is in the form of a plastic, rigid or semi-rigid card substrate. In some embodiments, the card substrate 108 has a width 168 of 2.125 inches and a length 169 of 3.375 inches, as indicated in the simplified top views of FIGS. 4 and 5.

[0040] In some embodiments, the transport mechanism 158 feeds individual card substrates 108 along the processing path 156 with the short edge 170 leading, as shown in FIGS. 3 and 4. In some embodiments, the transport mechanism 158 feeds individual card substrates 108 along the processing path 156 with the long edge 172 leading, as shown in FIGS. 5 and 6.

[0041] In some embodiments, the transfer roller 150 has a circumference that is substantially shorter than the circumference of conventional card substrate transfer rollers, such as conventional transfer roller 174 indicated in phantom lines in FIGS. 3-6. As mentioned above, such conventional card substrate transfer rollers 174 are selected to be large in order to provide the desired high heat capacity (e.g., 21 J/°C per inch of roller length) believed to be necessary to provide satisfactory transfer lamination operations on card substrates 108.

[0042] Such conventional card substrate transfer rollers 174 generally rotate less than two times during the performance of a transfer lamination operation on conventional card substrates 108. That is, a circumference of the conventional transfer roller 174 is generally greater than one-half of the length of the conventional card substrate 108. For example, conventional card substrate transfer rollers 174 generally have a diameter 176 of approximately 0.688 inches and a circumference of approximately 2.161 inches. As a result, the conventional transfer roller 174 will undergo approximately 1.56 revolutions about a central axis 178 when laminating a card substrate 108 with the short edge 170 leading (FIG. 4), and the conventional transfer roller 174 will undergo approximately 0.983 revolutions when laminating a card substrate 108 with the long edge 172 leading (FIG. 5). Accordingly, conventional card substrate laminating devices utilizing conventional transfer rollers 174 perform lamination operations on conventional card substrates 108 by rotating significantly less than two times.

[0043] In some embodiments, the transfer roller 150 is configured to rotate more than two times during the performance of a transfer lamination operation on a conventional card substrate 108 regardless of whether the substrate 108 is fed with the short edge 170 leading (FIGS. 3 and 4), or with the long edge 172 leading (FIGS. 5 and 6). In some embodiments, the transfer roller 150 has a diameter 180 that is less than 0.388 inches.

[0044] In some embodiments, the transfer roller 150 has a heat capacity that is significantly less than the heat capacity of conventional transfer rollers 174. This allows the transfer roller 150 to quickly heat up from an ambient temperature to a laminating temperature, at which a laminating operation can be performed on a card substrate 108. In some embodiments, the heat capacity of the transfer roller 150 is less than 12 J/°C per inch length. In some embodiments, the heat capacity of the transfer roller 150 is less than 7 J/°C per inch length. In some embodiments, this relatively low heat capacity of the transfer roller 150 allows the heating element 152 to heat the transfer roller 150 from an ambient temperature (i.e., approximately 20°C) to a laminating temperature, at which a lamination operation can be performed on a card substrate 108, within 40 seconds.

[0045] The relatively low heat capacity of the transfer roller 150 provides significant advantages over conventional high heat capacity (i.e., > 21 J/°C per inch of roller length) card substrate transfer rollers 174. For example, due to the relatively large heat capacity of the conventional card substrate transfer rollers 174, it takes significantly more than 40 seconds to heat up the rollers 174 from the ambient temperature to the laminating temperature. As a result, laminating devices utilizing conventional card substrate transfer rollers 174 require a significant warm-up time before a lamination operation can be performed. In order to avoid such long warm-up times, users may tend to leave such conventional card laminating devices on, resulting in a significant waste of energy. The laminating device 102 having a relatively low heat capacity transfer roller 150, allows users to keep the device 102 off until needed due to the fast warm-up time, thereby eliminating the energy waste associated with the conventional card substrate laminating devices.

[0046] Additionally, conventional card substrate transfer rollers 174 require a relatively high amount of energy to raise their temperature from the ambient temperature to the laminating temperature due to their high heat capacity. This further increases the amount of energy that is required to perform a single lamination operation, over that required by the laminating device 102 utilizing the transfer roller 150.

[0047] Some embodiments are directed to a method of laminating a card substrate 108 using the laminating device 102. FIG. 7 is a flowchart illustrating such a method in accordance with embodiments of the invention. At 190, a card substrate 108 is fed along a processing path 156 in the direction 166 using a transport mechanism 158. In some embodiments, the feeding of the card substrate 108 in step 190 is performed with the short edge 170 of the card substrate 108 leading, as shown in FIGS. 3 and 4. In some embodiments of step 190, the card substrate 108 is fed with the long edge 172 leading, as shown in FIGS. 5 and 6.

[0048] At 192, the transfer roller 150 is heated. This heating of the transfer roller 150 may occur before and/or during the feeding of the substrate in step 190. In some embodiments, the transfer roller 150 is heated using an internal heating element 152, shown in FIG. 3. In some embodiments of step 192, the transfer roller 150 is heated from an ambient or room temperature to a laminating temperature within 40 seconds.

[0049] At 194, a portion (i.e., a patch or a portion of the thin film laminate) of a transfer layer 120 of the transfer ribbon 104 is pressed against a surface 106 of the card substrate 108 using the transfer roller 150, as shown in FIGS. 3 and 6. In some embodiments, step 194 is performed while the transfer roller is at a temperature that is greater than or equal to the laminating temperature. In some embodiments, the transfer layer 120 includes a patch laminate. In some embodiments, the transfer layer 120 includes a fracturable thin film laminate.

[0050] At 196, the transfer roller 150 is rotated about the central axis 178 at least two times during the lamination operation (step 194). In some embodiments, the rotation of the transfer roller is driven by the feeding of the card substrate 108 along the processing path 156. In some embodiments, the rotation of the transfer roller 150 is driven by a motor (not shown) under the control of the controller 116. The transfer layer 120 is bonded to the surface 106 of the card substrate 108 in response to the performance of steps 194 and 196.

[0051] At 198, a carrier layer 122 of the transfer ribbon 104 is removed from the portion of the transfer layer 120 that was bonded to the surface 106 during steps 194 and 196 to complete the laminating operation on the card substrate 108. The resultant laminated card substrate 108 includes a transfer layer 120 over the surface 106 of the card substrate 108.

[0052] Although the present invention has been described with reference to preferred embodiments, workers skilled in the art will recognize that changes may be made in form and detail without departing from the spirit and scope of the invention.
