TW436272B - Manufacturing method for aligning zipper patterns - Google Patents

Abstract

This invention relates to a manufacturing method for aligning zipper patterns, which prints or knits and embroiders the required patterns, texts, or marks on a zipper continuous cloth surface. The opposing zipper hems are formed by cutting along a center of the continuous cloth through a cutter (or laser cutter) provided at the front of the sewing machine. The middle of two zipper hems after cut is immediately sewed with zipper teeth. By means of the dragging force of the sewing machine while sewing, such that the patterns, texts, or marks do not misaligned or mismatched due to errors resulted from the manufacturing processes, or other factors, such as strength, conveyor speed or different tension.

Description

r 43 / ^ ^ A3 627 2 I f V. Description of the invention (1) < Industrial field > _ The present invention provides a graphic, lettering or mark on a zipper, which can match or correspond without affecting the zipper and chain The suture defect formed between the teeth (such as the depth of the stitches and the situation of eating cloth, making the graphics, words or marks on the zipper mismatch). < Past art and its problems > There are three types of graphics, lettering or marks on general zippers: usually required patterns, letterings or marks, which are woven on a dobby or a jacquard loom during the weaving of the tape. Into the continuous tape, or printed or dyed on the continuous tape before the zipper element row is attached to the continuous tape, but 'the required graphics, typefaces or marks are placed on the completed On the zipper cloth, the following defects still exist in the manufacturing process, as described below: (1) Because the two zipper cloths are made separately, the zipper cloth is in the manufacturing process, and it is often easy to weave different due to latitude and longitude. Different conveying machine speeds, or rollers are worn or pulled, which makes the strength of the zipper cloth different. In contrast, it is easy to make the zipper cloth regardless of the printing, dyeing or weaving patterns, words or marks, which cannot match each other. Mixed (see Figure 1). '(2) Of course, the completed zipper is attached with a zipper sprocket row on the inside of the zipper cloth, so although the required graphics, words or marks may be printed or dyed, the printed or dyed Graphics, typefaces or marks are difficult to complete, and are prone to defects and imperfections. In contrast, the aesthetics of the zipper is destroyed. Considering the graphic, typeface or mark placed on a custom zipper in the manner described above

Page 4 of 436272 V. Description of the invention (2), there are still all kinds of missing letters that cannot match each other, unreadable letters or look unattractive. Someone has created a method for manufacturing zipper strips (the application number is 7 9 1 0 6 5 6 No. 9 (see Figure 2), the method is (a) two columns are arranged at intervals in the length direction of the continuous tape, and the patterns match each other; (b) side by side Relevant feed relative tapes are directed towards the sprocket attachment station; (c) Check the corresponding line marks during the continuous continuous tape feed; (d) Control the relative tape feeds so that the corresponding line marks are marked. The inspection confirms that they are aligned with each other, then the tape continues to feed, and the corresponding line marks are verified to be not aligned with each other, then the feeding of the leading tape is stopped, so that the corresponding line marks are aligned with each other; (e) at the sprocket attachment station , It is equipped with two rows of continuous sprocket teeth on the longitudinal inner edges of the opposite cloth strips, so that the line marks are aligned with each other. At first glance, although the above methods can make the figures, words, or labels on the continuous cloth match each other, the following disadvantages still exist in the production process: (1) When the continuous tape is set on the line If the marks are not aligned with each other through electrical eye inspection, you must stop the machine to adjust the line marks to align with each other, and then continue to move. If the line labels are not aligned with each other during the production process, stop the operation again. Always pay attention to whether the line marks on the continuous tape are aligned. If they are not aligned, you need to stop and adjust the alignment, and then continue to operate again, which is troublesome and wastes the production process.

Page 5 436272 V. Description of the invention (3) (2) Use two conveyor wheels to guide and convey the continuous cloth belt to both sides, then the continuous cloth belt. When the belt is in the conveyance, the conveying speed of the two sides of the conveyor wheels is different. In addition, use the electric eye to control the alignment of the line marks on the continuous tape. If the alignment is not aligned, adjust the controls separately, which takes time to operate (see Figure 3). (3) Since two continuous fabric tapes are stitched, they must be aligned after being aligned in a row, and the two continuous fabrics are knitted separately by warp and weft knitting machines with different machines, so the tension and tension produced by them are different. , And the error caused by the figure, typeface or mark above it is between 80% and -85%, and it can still be seen that the two halves have different degrees of matching.丨-(4) If the sewing sprocket in this case is driven by a general motor, but when the current is different, the depth of sewing stitches will be different, which will cause the zipper cloth to be pulled. ), Can not keep the flatness of the zipper cloth. (5) The rollers set in this case are driven by ordinary motors, which make the rollers different in tension and speed, which may cause different seams of the zipper tape. It is necessary to adjust the rollers frequently. In addition, when the rollers are used for a long time, the surface is easy to wear and its true circle The degree is not enough (see Figure 4). It is often necessary to replace another new roller, and the cost is a large expense, which is not in line with economic benefits. In addition, in order to solve the various defects caused by the above-mentioned zipper tape (such as using Γ 'electric eyes to control the row marks on it, alignment or not, and then continue to adjust after adjustment, troublesome and time-consuming, easy to form a defective rate; high unit price of zipper; zipper The tape is pulled in the stitching of the needle; often the rollers are replaced, etc.), and often the user is sick.

Page 6 436272 V. Description of the invention (4) The inventor then carefully designed the invention, in order to eliminate the lack of habit and retain the original utility of the zipper cloth, and obtain faster, so that the graphics, typefaces or marks can better match each other It will not affect the alignment of the zipper graphics due to different strengths or tensile strengths of the conveying wheels, which is practical and economical. The purpose of the present invention is to improve the lack of the conventional zipper, and to provide a cutter (or laser cutter) in front of the sewing machine, cut in the middle of the continuous cloth to form two zipper cloth edges, and Sprockets are sewn immediately in the middle of the two zipper cloth edges, and the sprocket is stitched by the sewing machine to make the sprocket stitches on the inside of the middle of the two zipper cloth edges, and at the same time, the graphics, words or marks on the zipper are not caused by the manufacturing process Factors such as errors, strength, and different speeds and tensions of the conveying machinery cause mismatch and asymmetry. With regard to the technical means and structural features used by the present invention to achieve the purpose, the following is a detailed description of the preferred embodiment shown in the accompanying drawings: < Illustration of drawings > A top view that matches each other.
