Abstract

PURPOSE:To prevent rumples and to enable selection of hardness of winding by quickening the feeding speed of resilient feed roller provided between take-up and cross rollers when compared with feeding speed in previous process while making the cross roller winding speed selectable. CONSTITUTION:A cloth 1 is fed through a take-up roller 2 and a pair of pressure rollers 3 then bent and applied tension by a switch roller 4 to be fed to a pair of feed rollers 6. Here the feeding speed of roller 6 is higher than that of roller 2 while the cloth 1 is held tightly in lateral direction by means of a pair of resilient members then stretched between the rollers 2 and 3 and developed through a roller 4 by the component of tension thereby rumples produced at the roller 3 are temporarily eliminated. While since the winding speed of roller 5 can be selected freely against the feeding speed of roller 6, the cloth can be wound tightly by making the feeding speed of roller 6 higher than the winding speed of roller 5.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is capable of winding a cloth woven with a reed on a loom on a cross roller without wrinkles, and also allows the winding hardness of the wound cloth to be freely selected. This is related to the method of preparation.

Conventionally, when a cloth woven with a reed on a loom is wound around cross rollers, as shown in FIG. The cloth 1 sent out from the pressure roller is placed on a pair of wind-up rollers 7 via a twist roller 4f, and is wound up by the cross roller 5 and the surface friction force due to the self-weight of the cloth wrapped layer wound around the rollers. It had been. Here, for normal take-up, the speed ratio between Ra 2 and wind-up low rough is approximately 1:101.
5 to 1.105 f, therefore, a certain draft is applied, and a certain tension is applied by the twist roller 54 so that the wrinkles generated on the take-up roller 2 are spread out. However, a pair of wind up rows 27
and the cross roller 5 which is mounted on the cross roller and driven, there is a wind-up roller, which is driven only by the surface friction force due to the weight of the cloth layer wound around the cross roller, and when viewed in the entire width direction of the cloth, there is a wind-up roller. There are areas where the degree of adhesion is not uniform between the material and the cloth wrapping layer, and depending on the type of cloth, large gripping spots may occur, and these gripping (nip) spots may cause unevenness in the direction of travel of the rolled cloth. There is a drawback that creases occur and these creases are directly wound onto a single cross roller.

SUMMARY OF THE INVENTION The present invention aims to solve the above-mentioned drawbacks, and its purpose is to make the cloth wound on a cross roller completely free of wrinkles and to be able to freely select the hardness of the wound cloth. It is an object of the present invention to provide a method for winding up a woven fabric, and the present invention provides a pair of feed rollers covered with an elastic material between a take-up roller and a cross roller, and adjusts the feeding speed of the feed rollers to a taper roller o-5. The speed of the cloth fed out by the resher roller is slightly higher than that of the cloth to give full tension to the cloth, and the speed of winding the cloth by the cross roller is set at the same speed or slightly faster than the speed of the cloth fed out from this feed roller. It is characterized by being rolled up.

Next, an example of an apparatus for carrying out the method of the present invention will be explained with reference to the drawings. In FIG. A pusher 6 is a pressure roller that comes into pressure contact with the take-up roller 2, and is fed out from between the take-up roller 2 and the pressure roller 3 of the cloth 1 cigarette. Reference numeral 4 indicates a line that serves to spread the cloth and remove wrinkles between the take-up roller 2 and the cross roller (described later); - a chill roller, and a 5-piece cross roller, which is separate from the take-up roller 2; It is configured to be driven by A feed roller 6 is provided between the twitch roller 4 and the cross roller 5, and this roller is made of an elastic material such as a urethane sheet, home rubber, or rough rubber, and is used to feed the cloth sent out from the take-up roller 2. It is configured such that it is driven at a speed somewhat faster than that of the engine, and the speed ratio thereof can be varied as appropriate.

One example of an apparatus for carrying out the present invention is configured as described above, in which a woven cloth 1 is sent out between a take-up roller 2 and a pair of brain rollers 3, and is bent by a twist roller 4. Tension? It is applied, spread and sent to a pair of feed rollers B. Here, compared to the speed of the cloth sent out from the take-up roller 2, the speed at which the cloth is sent out from the pair of feed rollers 6 covered with an elastic body to the cross roller 5 side is somewhat faster, and the cloth is fed out from a pair of elastic body The fabric is tightly gripped in the width direction of the fabric, pulled between the take-up roller 2 and the feed roller 6, and spread by the twist roller 4 using the force, so wrinkles generated from the take-up roller are temporarily eliminated during this time. I get K when it happens.

On the other hand, even if the winding speed of the cross roller 5 is between the feed roller 6 and the cross roller 5, the winding speed of the cross roller 5 can be freely selected relative to the speed of the feed roller 6. If the take-up speed is increased somewhat, the cloth will become taut and tightly wound.

In addition, if the surface of the cloth itself has irregularities due to the type of cloth (for example, texture, threading, etc.), the surface layer of the cloth wrapping of the cross roller 5 will also have irregularities, and when looking at the entire width of the cloth, there may be slight differences in the outer diameter of some parts. If there is a difference in winding circumferential speed and wrinkles or separate wrinkles occur near the take-up roller 2, lower the winding speed ratio between the feed roller 66' and the cross roller 5 to soften the winding speed. gJ on the cross roller 5 can be prevented.

FIG. 3 shows another example of an apparatus for carrying out the method of the present invention, in which the cross roller 5 is replaced by a pair of feed rollers 6.
．． It differs from the first embodiment described above in that it is configured to be placed on top of the device 6'. That is, the cloth 1 sent out from the take-up roller 2 and the pressure row 23 passes through the twist roller 4 and the guide roller 8, and then reaches the feed roller 6.
Don't send it to 6'. Here, since the feeding speed of the feed roller 66' is somewhat faster than the feeding speed of the take-up roller 2 and the feed roller 6, the dirt generated on the take-up roller 3 is spread by the twist roller 4 and eliminated, and remains as it is. It is coated on the surface of the feed roller 6' without wrinkles and is wound up on the cross roller 5 driven by frictional force. In this case, the driving force of the cross roller 5 is the frictional force between the feed low end' and the surface layer of the cloth wrapping of the cross roller 5. Since it changes depending on the M amount of the wound cloth layer, the change in the cloth winding hardness is independent of the cloth tip J of the take-up roller 2 and the filter roller 66' (this means that the wrinkle spreading force generated during this (meaning unrelated) This is possible through Crossroller's own acceptance and change.

The present invention provides a pair of feed lawns made of an elastic material between the take-up roller and the cross roller when reed-woven fabric is wound up by the cross roller as described above, and the speed of the cloth sent out from the feed roller is controlled. Tension is applied to the cloth by making it somewhat faster than the speed of the cloth fed out by the take-up roller and the pressure roller, and furthermore, the speed at which the cloth is wound up by the cross roller can be appropriately selected relative to the speed of the cloth fed out from the feed roller. Therefore, compared to the conventional winding method for reed-woven cloth, the wrinkles caused by the take-up roller and the pressure roller are tightly gripped uniformly across the width of the cloth by a pair of feed rollers made of elastic material. Therefore, wrinkles 1, which occur on the cross rollers depending on the type of cloth, can be eliminated by increasing the speed of the feed rollers to some extent, making use of the tension of the cloth.On the other hand, wrinkles 1, which occur on the cross rollers depending on the type of cloth, can be eliminated depending on the winding speed of the cross rollers and the characteristics of the woven fabric. Either constant speed or increased speed can be freely selected and resolved, resulting in the effect of obtaining the optimum cloth winding hardness.
