TRACTION UNIT FOR WELDED YARN

The Technical Area

This invention is related to a drawing unit which is employed in the production of welded thread.

The Previous Technique

Manufacturing of fantasy yarns in the Ring Spun Yarn is of utmost importance in new marketing capabilities and the creation of new production types.

Presently, fantasy yarns, which are more commonly known as injected yarn", are manufactured by means of including a piping with the desired color and NE value and produced from any raw material or by means of including piping of required amount between folded yarn.

Another method used during manufacturing of fantasy yarns is realized by including raw piping of different colors and /or in required amounts within the yarn, by means of adding electro mechanical systems on the ring machine drawing unit. The required amount of piping is injected between the folded yarns by changing the cycles of the exit rollers of the drawing unit in a controlled manner or by stopping them, by means of the electro mechanical systems included on the machinery.

With the methods used during the present day, we are able to include only a single type of piping within the yarn. Each one of the manufacturing method is capable of being applied only on the machine where it is being applied and they require very high investments.

The method regarding manufacturing of fantasy yarn and the device is explained in the international patent document numbered WO2008068294. Ring yarn machine is used in manufacturing fantasy yarns and the machinery coinsists of at least qty. two twisted yarns and fiber yarns arriving from the traction device. The device holding the carrier yarn feeds at least qty. one supporting yarn package. Adjustment of the ring spinning machine for concentrated fiber is explained in the United States patent document numbered US6263654. The ring spinning machine which is adjusted for concentrated drawn but not folded fiber contains a cylinder that carries the fiber yarn. The cylinder is provided by means opening holes on the external muff. The external muff of the cylinder is supported by a framework and the holes provide frequent loops.

Methods and devices are explained in the United States patent document numbered US2007137165 for manufacturing fantasy yarns. The aim of the invention is to provide a method to re manufacture fantasy yarns that had been manufactured previously. Initially the model fantasy yarn is passed through the sensor for measuring purposes and the diameter of the fantasy yarn is continuously measured and the measured diameter data is evaluated and the occurance of the effect is determined. The folding adjustments are adjusted by means of the occurance of the effect and used for the manufacturing of fantasy yarn.

Spinning machine traction device of the invention (1);

- Rear traction cylinder with at least one groove, operated by a motor and where transfer of movement is provided by means of sprockets. This is where piping (Fl,2,3) produced from any raw material enters, in order to be bent or tilted and become a yarn. (2)

- Medium traction cylinder with at least one groove, operated by a motor and where

transfer of movement is provided by means of sprockets. There is an apron on it. (3)

- Pre traction cylinder with at least one groove, operated by a motor and this is where the fiber (El, 2,3) transfer of movement of which is provided by means of sprockets exits as a yarn (Ϊ) (4)

- At least qty. 1 rear muff (5) which is located on a mil and that can freely rotate, which receives its drive from surface pressure and rear traction cylinder (2) and which

provides for applying controlled traction to the first fiber (Fl .2.3) which enters the traction system in the form of a piping (El .2.3), received from the rear traction system.

- At least qty. one freely running upper middle muff (6) which is located on a bearing mill, and which shelters an apron (7) located on it by means of a cage located on it and

that enables the apron (7) to turn in a controlled manner.

- at least qty. 1 upper apron (7) that can freely move on a cage and an upper middle muff (6) and which is located on a grooved medium traction cylinder (3), and which provides control of the fiber (F 1 ,2,3) by means of the movement caused by the friction and pressure forces of the medium traction cylinder (3) and upper medium muff (6).

- At least qty. 1 lower apron (8) that stays in a taut state on the grooved medium traction cylinder (3) by means of a tie bar, which turns by means of the medium traction cylinder's drive and which provides control of the fiber (El, 2,3) between the upper apron (7) and itself.

- At least qty. 1 exit forward muff (9) which is located on a bearing mill so as to move freely, that squeezes and holds the fiber (Fl ,2,3) selected to become a yarn by means of the pressure applied by the grooved forward traction cylinder (4) on it and which sends it forward without interruptions and like wise provide the bending of the yarn.

- At least qty. 1 air suction pipe (10) that sucks the fiber (El,2,3) which were unable to hold on to the forward muff (9) and which is located below the forward traction cylinder (4). - A piping guide (11) which is located before the rear traction cylinder (2), which provides guiding to the piping (F 1,2,3), which delivers the piping between the grooved rear traction cylinder (2) and the rear muff (5). It has a hole in the middle and the number of it is equal to the number of piping (F 1,2,3) which enter the unit.

Surface of the front muff (9) is covered, preferably with rubber based material. It can be of various thicknesses but the thickness must be uniform along the length. The rubber material may be on a ring with a hole in the middle or it may be part with a hole manufactured completely from the same material as the muff (9). The thickness of the rubber coated part of the muff or the thickness of the external diameter of the muff (9) may be as required. The limit of the diameter is identified by the distinctive yarn making limitation of a spinning machine. The front muff (9) determines the quality and the smoothness of the yarn (I) by means of the fiber (El, 2, 3) which it dispatches. The fibers (E 1, 2, 3) squeezed between the front traction cylinder (4) and the front muff (9) are continuously pulled and folded by the spindle which turns with a specific rotation. The yarn (Ϊ) which leaves the front traction cylinder (4) passes through the yarn guide is bent between buckle bracelet and spindle and it is rolled around the spool which is on the spindle.

The raw material of upper apron (7) and the lower apron (8) is a rubber weighted component.

Finesse, thickness and the smoothness of the yarn (I) is determined with the control of the fibers (E 1 , 2, 3) by the front muff (9) at the traction unit (1) at the spinning machine of the subject invention. At the traction unit (1) front muff (9) and the front traction cylinder (4) provides for inclusion of the fibers (E 1, 2, 3) into the yarn (I) that had been forwarded and controlled by them. No matter what the thickness of the fibers (E 1, 2, 3) transported between the medium traction cylinder (3) and the aprons (7, 8) are, only the fibers that get caught front muff (9) and the front traction cylinder (4) are transported forward.

The front muff (9) of the spinning machine's traction unit (1) is shaped in order to provide the control the fibers (Fl .2.3). In order to control and dispatch the required amount of fibers (E 1 , 2, 3) and have them welded to the yarn (I), one or more than one canal (92.93) is opened on the muff, (9), throughout the circumference of the muff, with the required length, width and depth. The canal (92.93) is being positioned on the muff (9) so as to be on the flow path (corridor) of the fibers (E 1, 2, 3) and form a 0° angle.

In the preferred application of the invention, the canal (92.93) is being positioned so as to be perpendicular to the front traction cylinder (4), and parallel to the flow direction of fiber (Fl .2.3) and yarn (I) or on the path of the fiber (corridor).

In the preferred application of the invention, qty. two canals are opened around the 10 muff (9). The canals (92.93) that have been opened are parallel to each other and they are qty. 1 less than the number of piping (Fl .2.3) that enter the traction unit (1). There exists a muff (9) surface without any canal and it is being welded to the fibers (Fl .2.3) that correspond to the normal surface, to the fibers (E 1) that correspond to other two canals, so that the fiber (El) that correspond to the normal surface and which is used to produce main yarn (Ϊ) and the fibers (E 2, 3) that correspond to the canals (92.93) are joined together, to compose the yarn (I). Canals (92.93) that open to the muff (9) cover all around the the muff (9) in order to control the entering fiber (E 2, 3) and provide for their welding to the yarn (I). Like wise, a surface on the muff (9) that has no canal is obtained and the canal (92.93) is started and the end of the surface that has no canal, so that the fiber (El) is pressed at the normal surface between the front muff (9) and the front traction cylinder (4) where there is no canal (92.93) and sent forward.

The width of the fibre (E 2, 3) corresponding to the canals (92.93) and the width of the fibre (E l )arriving at the notmal surface between the canals (92.93) that are used in form the yarn (I) is related to the width (Ne) of the piping (Fl .2.3) that enter the traction unit (I), the width and the depth of the canal (92.93) on the muff (9).

While the piping (F 1) that will form the main yarn is being transported on the surface located in between the canals (92.93) at traction unit of the invention, the piping (F 2, 3) in two different colors and /or raw material of the piping (F 1) which is desired to be welded to the main yarn (A) and which will compose the main yarn (Ϊ) are being transported on the canals (92.93) located at the two sides of the normal surface.

There are piping guides (1 1) at the traction unit (1), number of which is equal to the total of number of canals (92.93) where the fiber (E 2, 3) to be welded to the main yarn (I) is carried and the number of surfaces without canals in between the canals (92.93) where the fiber (E 1) which constitutes the main yarn (I) is carried.

In the preferred application of the invention, qty. three piping guide (11) is used. While qty. two guides (1 1) are feeding to the unit, the piping (F 2, 3) to be welded to the main yarn (Ϊ), the other guide (1 1) is feeding the piping (F 1) that will compose the main yarn (Ϊ). In another preferred application of the invention, three eyed piping guide (1 1) is used. The most important point in this is to allow the pipings (Fl .2.3) to enter the traction unit (1) in a controlled manner.

By employing qty. three piping guides (11) at the traction unit which is the subject of the invention, qty. three pipings (Fl .2.3), in place of one, are allowed in between the grooved rear traction cylinder (2) and the rear muff,. At the traction unit (1), all sidings (Fl .2.3) are subjected to traction according to their thicknesses during the input (Ne) into the unit (1) between the rear traction cylinder (2) and the medium traction cylinder (3) and between upper - lower aprons (7, 8), together with grooved forward traction cylinder (4) and the front muff (9).

The fiber (E 1) which enters the unit (1) and that comes to the front muff (9) up to the normal surface without canals by allowing it through the center of the rear muff (5), is transferred untirreptedly to become a yarn (I). The fiber (E l) which had been transferred in this manner makes up the main yarn (I). The siding (F 2, 3) which eneters the unit so as to coincide with the canal (92. 93) is transferred along the canal (92. 93) located on the front muff (9), by means of the forward traction cylinder (4). Due to the muff continuing its continuous revolving actions, the fiber (E2.E3) coinciding the canal (92.93) is not jammed in between the forward muff (9) and the forward traction cylinder (4) and not transmitted forward. The fiber (E 2, 3) that could not be sent forward is sucked by the air suction pipe (10). On the other hand, fiber (E2.E3) that corresponds to the surface without any canal, located at the end of the canals (92.93) and that are squeezed in between the front traction (4) and the forward muff (9) are sent forward and welded to the main yarn (I) which is composed by the fiber (E 1) that had been transferred after it had corresponded with the surface without any canal.

The surface area of the muff (9) is shown on Figure 4. The depth, length, width of the canals (92.93) on the surface of the muff (9), the positions of the canals ((92.93) relative to each other together with the welding points of the fibers (E2.E3) with the fiber (El ) which conform the main yarn (I) can be adjusted. By determining the canal (92.93) starting points in the traction unit of the invention, the welding points of the fibers (E2.E3) with the main yarn (I) are also changed. By means of the consecutive canals (92.93) located at both sides of the normal surface, when welding of a fiber (E2) to the main yarn (Ϊ) is completed, the other fiber (E2) begins to weld to the main yarn (I).

In another application of the invention, with canals (92.93) located at both sides of the normal surface (9) with the same length and the same beginning and ending points, the fibers (E2.E3) are welded at the same time and at the same amount of yarn (Ϊ). In another application of the invention, welding intervals of fibers (E2.E3) to the main yarn (I) is increased by means of canals (92.93) of different lengths on each side of the normal face of the muff (9). Fibers (E2.E3) are welded during differing times, in different amounts by means canals (92.93) differing origins and differing end points. In such a situation, as the length of the surface without canals which is left outside the canal length (e.d) is increased, the amount of fiber (E2.F3) welded to the main yarn (I) also increases. Canal lengths calculated from the length (d.e) of the surface (a.b) without any canal derived from the perimeter (c) of qty. 10 muffs (9), shows the distances of welding formed by the fibers (E2.E3).

The welding periods of fibers (E2.E3) to the main yarn (I) are adjusted by means of determining the lengths of surfaces without any canals and the starting points of welding.

In order to weld the fiber to the main yarn, the length of the surface without any canal needs to be at least 1mm. The width of the canal (92.93) to be opened on the muff (9) changes according to the thickness (to Ne) of the piping (Fl .2.3) which enters the unit. On the other hand, in a preferred application of the invention, when the canal (92.93) width varies between 1 - 10 mm, canal depth varies between 0.5 - 8 mm.

Around this basic concept, it is possible to develop various applications of a spinning machine (1) for manufacturing of welded thread. The invention cannot be limited to the examples provided here. The essence is as provided at the requests.
