JPH11200234A - Device for setting cloth to spreading machine and correcting strain of weft stitch of the cloth - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a device for correcting the strains of the weft stitches of cloth, capable of delivering the cloth having the weft stitches arranged at a right angle to warp stitches at the exit of the cloth by allowing the various strains of the weft stitches to be absorbed at a central place between a cloth exit and the cloth-delivering roller of the spreading machine. SOLUTION: The correction of the stains of the weft stitches of a cloth is carried out by dividing the stains of the weft stitches into portions n which warp stitches precede and portions in which the warp stitches relay, pressing the preceding portions of the cloth with pins at the center between a cloth-feeding roller 14 and a cloth exit, detouring the flow of the cloth only at the preceding portions to allow the stains to be absorbed, and subsequently delivering the stitch-corrected cloth from the cloth exit. The pins are horizontally arranged in the number corresponding to the width of the cloth, and a sliding load is applied to the pins and a pin receiver 8 with magnets, plate springs, etc., so that the pins can resist to the pressure of the cloth and can easily slide. When the pins are connected to wires having righting moments, the pins can rapidly respond to various strains, and two upper and lower rollers are disposed at each of the tips of the pins to increase the absorption of the preceding portions.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION Although the horizontal lines of a piece of cloth must pass straight at a right angle to the vertical lines, the horizontal lines have various waveforms in the process of winding and transporting the fabric. It has such distortion. Since the distortion of the horizontal land can be corrected during the piling by the spreading machine in the cutting process, the transparent cutting and the lamination of the horizontal land can be performed.

[0002]

2. Description of the Related Art It has been considered impossible to correct the distortion of the eyes of a horizontal ground by a reversing machine. For this reason, luxury products are manually piled up, which requires a great deal of labor and time. In addition, since materials that stretch like a knit cannot be processed by hand, the only way to do it is to use a reversing machine to ignore the horizontal lines.

[0003]

At the cloth exit, the distortion of the various horizontal lines is completely absorbed between the cloth feed roller and the cloth exit of the reversing machine. The task is to ensure that the cloth that has passed through is sent out.

[0004]

The distortion of the horizontal background is divided into a leading portion and a lagging portion of the vertical portion of the fabric width, so that the leading portion is delayed and aligned. For this reason, the preceding portion is detoured by the preceding portion between the fabric feed roller and the fabric outlet to absorb the distortion. As a means, the cloth can be aligned at the cloth exit by pushing the cloth in accordance with the difference between the leading parts and adjusting the part to the part that is late.

[0005]

BEST MODE FOR CARRYING OUT THE INVENTION The number of pins equal to the length of a cloth width is horizontally arranged on a pin support. The tip of the pin should be spherical to minimize friction with the fabric. When the fabric is pushed in, the pin is provided with a light holding force by using a magnet, a leaf spring, or the like so that the pin has a fixing force capable of withstanding the fabric pressure and can slide lightly manually. Also, holes are provided at the same positions on the side surfaces so that a large number of pins can be quickly slid, and they are connected by a resilient wire. The pushing of the fabric by the sliding of the pin is made possible in the preceding part by absorbing the distortion by detouring the flow of the fabric. In order to further enhance the absorption effect, take the space where the fabric passes before the tip of the pin, and set two rollers in parallel at the top and bottom of the tip of the pin. By pushing, the distance of detour becomes longer, and the amount of strain absorption increases. Set the pin and roller that have the above functions into a single unit with the pin holder, and place the device on the cutter moving plate attached to the reversing machine or between the fabric feed roller and the fabric outlet. Attach so that the tip of the pin hits the cloth flowing down from the cloth almost at a right angle.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS The fabric feed roller has a fixed property so that the fabric does not shift, and the fabric sent out therefrom flows freely to the fabric outlet. The shape is confirmed by visual reference or laser marker and the reference line is put out, the pin in the position that leads a lot is pushed deeper in the pin, and the pin in the position where the lead is less is pushed in shallowly, so that it can be deformed in various shapes FIG. 2 shows how the distortion of the horizontal land is corrected at the cloth exit by freely absorbing the distortion. If the distance of the dotted line of 13 is subtracted from the distance of 11 + 12, the distance becomes the preceding distance of 9. . Slide the pin so that it is. Next, the spreading machine is moved to the start position 23 in FIG. 1 to start stacking, returns to the stacking end position 24, cuts with a cutter, moves to the start position again, and repeats the stacking.

[0007]

[Effects of the Invention] Cloths have a considerable amount of distortion in the eyes of horizontal ground, and higher quality is increasingly required with the times. Correction of the distortion of the ground eye was an indispensable prerequisite, but it was not possible to align the horizontal land with a reversing machine. In the present invention, since the tendency of the distortion of the ground eyes is similar and continuous, once the slide of the pin is set once, continuous insemination can be performed only by finely adjusting every few sheets. It is a device that has a long-awaited and revolutionary effect in the industry, since it enables a heavy roll to be used to create a well-laid horizontal pile from a difficult manual operation.

Claims (1)

[Claims] 1. A pin having a fixing force to withstand a fabric pressure by a magnet, a leaf spring or the like and having a fixing force capable of manually sliding lightly is applied to the fabric at a right angle to the fabric at a position between the fabric feed roller and the fabric outlet of the reversing machine. Set the pins for the width of the fabric in parallel to the fabric feed roller, and push the fabric in with the pins. It absorbs distortion and can send out well-textured cloth from the cloth outlet. In sliding the pins, holes are provided at the same positions on the side surfaces of the pins so that a large number of pins can be slid in a short time, and the pins are connected by a resilient wire. Also, to increase the amount of strain absorption, set two rollers longer than the cloth width in parallel with the tip of the pin on the top and bottom of the front of the pin, and move between the two rollers and the tip of the pin. By allowing the cloth fed from the cloth feed roller to pass through, the effect of increasing the amount of distortion absorption with a slight slide of the pin is produced. Correct the horizontal distortion of the cloth by setting the above-mentioned device with two pins and two rollers as one unit with the pin holder on the cutter moving plate attached to the reversing machine or in the middle between the cloth feed roller and the cloth outlet. Equipment to do.
