FIELD OF THE INVENTION

The present invention generally relates to the field of stickers, more specifically to stickers made of a synthetic fabric.

BACKGROUND OF THE INVENTION

Stickers are used to mark an item or to add some color or ornaments. Thus, many stickers are attached to clothes, bags and the like. Typically, stickers are made of a line of decorative paper or fabric, adhesive material and a liner attached to the rear side of the sticker. When using a paper sticker and attaching the sticker to a shirt, the sticker is not integrated with the shirt, and looks distinct from the shirt's fabric. Thus, it's preferred to attach a fabric sticker to a fabric, for example attach a fabric sticker to a shirt, a shoe or a bag. Stickers made of Non-woven fabric look less natural on fabrics, and may shine or reflect light.

When cutting stickers made of a woven material, the edges remain unraveled which makes the stickers useless after some time. One option to prevent the unravel issue is to sew the edges, which is complicated or highly expensive. Thus, there is a need for a solution to prevent the unravel issue of stickers made of a woven material without sewing the edges.

SUMMARY OF THE INVENTION

The present invention discloses a sticker and a method based on hot-cutting process for producing adhesive sheets containing ex tractable ornamental forms, also defined as stickers. The sticker can be adhered on pliable substrates such as cloth, textile fabric, leather, plastic, suede, and the like. The sheets utilized as adhesive sheets can be made of textile fabric or cloth. The sticker comprises, at least partially, synthetic fabrics. The hot-cutting process provides both cutting the sheet according to the sticker design and heating the sticker edges to prevent the edges to unravel later on. The synthetic fabrics may be polyester, acrylic, synthetic suede, Trivera, Lorex, satin, nylon, rayon, acetate, spandex, lastex, and Kevlar and a combination thereof. Other synthetic fabrics may be selected by a person skilled in the art. In some cases, the sticker is made of a combination of fabrics, either synthetic or organic. For example, the synthetic fabric may be present in the sticker in a range of 30%-50% by weight of the sticker.

The hot cutting process may be a laser cutting process disclosed in details below, using an optical device which cuts the adhesive sheets or an a rolled sheet having the liner, the adhesive material and the sticker through a focused laser beam projected on the adhesive sheet surface. The adhesive sheets comprises the synthetic fiber, a layer of liner and adhesive binding them. When placing the sticker, the synthetic fiber is removed by the user from the layer of liner. Thus, the optical device moves the laser beam about the adhesive sheets according to the outlines of the planned/designed sticker and cuts the surface in the path of the laser beam. Additionally, the cut generated by the laser beam may be fragmented through a number of uncut tiny sections. The uncut tiny sections provide stiffness, strength and durability to the structure of the sticker. The sticker formed by the laser cutting process and exist inside the adhesive sheets can be easily extracted out from the liner and then be adhered to pliable substrates.

In some cases, the laser cutting process may be replaced by a cutting process using hot press molds with blade shaped ending. The hot press mold process is performed by pressing the mold against the adhesive sheet surface and cutting in the shape of the sticker. In some cases, the molds are heated to a predefined temperature to ensure prevention of split edges, for example according to the selected fabric. Another purpose of the heating process is to seal the edges of the sticker in order to make the sticker resistant against disintegration of the material. The stickers are produced according to the method disclosed in the present invention may be of any shape, texture, template, figure, print, title, ornament, image, silhouette, or decorative element for the purpose of decorating the pliable substrate. An exemplary case can disclose an optical device that focuses the laser beam on the surface of an adhesive sheet in order to create forms such as flowers, faces, balls, letters, and the like, through a laser cutting process. The optical device moves the laser beam along the surface according to the outlines of the planned sticker and cuts the surface at the trajectory of the laser beam. The optical device may omit tiny sections during the cutting process which remain uncut. The uncut tiny sections existing along the cut are formed in order to improve the structure durability of the sticker. In some cases, when a hot press mold cutting process is involved, the sticker production process may comprise creating the molds of the sticker first, and then utilize the mold for cutting the sticker. The process of creating the sticker can comprise heating the mold to a specific temperature, placing the mold in a dedicated device, place the adhesive sheet and any additional process or action conducted by a person who has skills in the art. The mold comprises a knife of any kind desired by a person skilled in the art. The knife may be placed according to the sticker, to separate the ornamental shape from the sheet material. The knife may be moved along a track to be located accordingly. The knife may be heated to close split edges of the fabric.

The process of creating the molds can also be facilitated or managed by a computerized system controlling the engraving process required to produce the molds. The mold produced for the hot press mold cutting process may contain tiny gaps as part of the mold outline in order to leave tiny uncut sections, in similar form as they are produced in the laser cutting based process.

The method disclosed in the present invention comprises preparing an adhesive sheet used to prepare the sheets that are planned to be utilized in the laser cutting process and convert them to be stickers. The process of preparing the sheet comprises coating the sheet surface with one or more adhesive materials that can be utilized to adhere the sticker to the target pliable substrates. In some cases, the adhesive materials can be composed of a single stratum of adhesive material. In some cases, based on the specific sheet material, or the specific pliable substrates material on which the sticker are designed to be applied, the adhesive materials may be composed of multiple strata, which each stratum may have a different functionality or purpose. In some cases, the adhesive sheet may be coated by multiple layers in order to obtain additional capabilities such as chemical resistance for certain chemical reactions, heat resistance, waterproofness and the like. In some other cases, diverse layers such as glaze, colourful paint, brightness or glittering addendums and the like, may be combined in the layering process in order to achieve diverse appearances of the sticker.

The laser cutting process in the present invention is performed by an optical device managed by a computerized system. The optical device can project a focused laser beam that cuts the adhesive sheet. The computerized system manages the optical device which maneuvers the laser beam about the adhesive sheet and cuts its surface in the path of the laser beam. An exemplary case can be with a sticker planned to be produced on an adhesive sheet. The computerized system transmits the needed commands to the optical device which maneuvers the laser beam in order to cut the adhesive sheet surface and produce the sticker. Additionally, the computerized system can send the needed commands to the optical device in order to adjust the operation of the laser beam, in case the cutting process is automated, and not performed by a person operating the cutting device. The computerized system may be designed to manage the laser cutting process through command batches. The command batches contain lists of commands used by the optical device to control the positions and the placements of the optical device and to lead the laser beam in accordance with the outlines of the sticker. In some cases, a command batch can include a portion of the commands required to produce one adhesive sheet and the adhesive sheet may be produced through more than one command batch.

The computerized system used to cut the stickers from the adhesive sheet may be designed to receive the outlines of the sticker and convert them to command batches that control the movement of the optical device. The outlines of the sticker may be received by the computerized system via image files in a computer digital format. In some cases, the image files may be produced through photographing the design of the sticker in a digital camera. The computerized system can also receive image files produced by a graphic art software. In some cases, the graphic art process may utilize a drawing pad or a touch pad which communicates with the graphic art software and translates input on the pad to sticker outlines and the shapes. The computerized system is designed to receive the image files, define the circumference outlines of the planned stickers out of the image files and generate the command batches for the optical device in order to cut the planned stickers. An exemplary case can be with stickers in the shapes of flowers. The flower shapes are received by the computerized system as an image file. The computerized system defines the specific outlines of the flower in the received image file, and then converts the defined outlines to command batches for controlling optical device and applying the planned flowers shaped laser cuts on the adhesive sheets. In some cases, defining the specific outlines out of the digital image may utilize some methods from the field of image analysis, such as pattern recognition, object recognition and the like.

One of the objectives of the present invention is to produce stickers that can remain stiff and firm during the adhesive action. Such stickers can comprise curved extensions, tiny areas, long wisps, thin straps, and the like. The stiffness and the durability of the sticker is shown when the person places the sticker on the surface (cloth, bag) can be achieved through fragmenting the laser cut with uncut tiny sections formed during the laser cut action. Thus, the computerized system may be able to receive the outlines of the stickers as described above and determine the appearance frequency, the sizes and the shapes of the uncut tiny sections. The length of the uncut tiny sections may be in the range of 0.1 -2mm or any length desired by a person skilled in the art. The computerized system is designed to calculate the positions and the structures of the uncut tiny sections along the planned laser beam trajectory and coordinate them into the continuous cutting action. The determination process of the uncut tiny sections which defines the appearance frequency, the sizes and the shapes of the uncut tiny sections takes into account the properties of the stickers such as the shapes, the sizes, the width, the length and the like, and the properties of the adhesive sheets such as the adhesive material type, fabric type and the like.

The stickers resulted from the laser cutting process are firm so they can be extracted out of the adhesive sheet via a simple gesture of the fingers such as pinching and then be adhered to the target pliable substrate. When placing the sticker on the garment, the user may first place the entire adhesive sheet on the garment, and only then remove/peel the portion of the adhesive sheet 220 that excludes the sticker (205 of figure 2).

The computerized system may also comprise multiple condition sets utilized to determine the requirements which the stickers must meet in order to be produced through the hot cutting process disclosed in the present invention. The condition sets held by the computerized system may comprise multiple parameters related to the structure of the stickers such as the minimal length of the stickers allowed, the minimal distance allowed among uncut sections, the minimal surface area required for the stickers and the like. The conditions sets may also contain parameters related to the adhesive sheet material such as the minimal width of the adhesive sheet and the like. An exemplary case can be with a sticker required to be produced on a specific adhesive sheet through the laser cutting process. The computerized system compares the properties' values of the sticker and the properties' values of the specific adhesive sheet with the parameters defined in the condition sets in order to validate whether the sticker meets the minimal requirements and can be produced on the specific adhesive sheet by the laser cutting process disclosed in the present invention. An additional example can be with the computerized system utilizing the condition sets to validate that distances between the uncut tiny sections meet the minimal requirements. The comparison process defined above and conducted by the computerized system can be performed by multiple iterations, when each iteration can receive some changes or adjustments at the stickers' properties' values or at the adhesive sheet properties' values. For example, a sticker is required to be produced on a specific adhesive sheet through the laser cutting process. The computerized system compares the sticker properties' values and the specific adhesive sheet properties' values with the parameters defined in the condition sets. In case one or more of the conditions in the condition sets are not met, the computerized system can pause the process in order to receive new or adjusted properties' values. Then, when the new or adjusted properties' values are received by the computerized system, the comparison process can continue as described above. In some cases, the computerized system may provide an alert or an error and then continue the comparison process without pausing or stopping it. In some cases, the computerized system may adjust the properties' values automatically without receiving any adjustments. The computerized system may also be designed to conduct a single iteration comparison process. In case of a single comparison process, the computerized system can omit the stickers that are not meeting the minimal requirements. In some cases, when the cutting process may be based on hot press molds, the conditions in the condition sett may have different parameters. For example, if the stickers are produced in a laser cutting process the distance measured between the uncut tiny sections may be different that in case a press mold cutting process is being used. In some cases, the temperature of the press mold may be take into considerations when a hot press mold cutting process is being used. In some other cases, if laser cutting process is being used, the heat of the laser beam may need to be calculated. BRIEF DESCRIPTION OF THE DRAWINGS
