Problems solved by technology
In order to make the upper and lower layers of chain teeth have better meshing at the same time, the double-layer tooth zipper needs to be made into a sized opening zipper in the state of meshing teeth. Difficult, there has been no breakthrough in technology, resulting in poor synchronization of the opening and closing of the upper and lower layers, and large resistance to opening and closing

Embodiment Construction
[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0034] A double-layer teeth opening slide fastener and a three-in-one type opening slide fastener manufacturing method and structure, the manufacturing method of the present invention, its technological process is as follows figure 1 Shown:
[0035] 1. First, sew a single tooth chain and a single wide cloth belt; and dye and dry to shape b to form a dyed chain belt; then carry out electronic or mechanical counting, cut the cloth belt and timing in the tooth reading area c. It uses the existing timing structure to transform it into an electronic or mechanical timing reading device. It compares the principle of gears and racks (that is, zippers are also a kind of rack), and uses sensors as timing reading devices. The tooth device is used as the fixed length, and is cut with a cutting tool at the required fixed length to obtain the required lengt...

The invention discloses a production method and structures of a double-layer-tooth open-ended zipper and a three-in-one open-ended zipper. Teeth are counted by stitching of a signal full-width woven belt and electronic or mechanical counting so that the length of the woven belt is determined by the number of teeth. When the woven belt is cut off and timed, the teeth are peeled off, folded and corrected to become a signal-side double-layer-tooth zipper belt by heating lamination or stitching. Signal-side double-layer-tooth zipper belts at left and right sides are installed at pull heads additionally provided with tongue-shaped guide pieces. The timed zipper belt is formed by alignment and combination of teeth. Ultrasonic cloth sticking and punching operation are carried out. A square lower stop and a bolt are provided with punching fixation. The other tail ends of the square lower stop and the bolt are fixed with upper stops so that a double-layer-tooth open-ended zipper is finished. As for the three-in-one open-ended zipper, the same production method is adopted by the signal-side double-layer-tooth zipper belt and electronic or mechanical counting is also adopted by the signal-side double-layer-tooth zipper belt in order to determine the length of the woven belt based on the number of teeth and to ensure correct engagement between zipper teeth of zipper belts. Meanwhile, advantages such as high automated degree and production efficiency are obtained.
Description
technical field [0001] The present invention refers to a double-layer tooth opening slide fastener and a three-in-one opening slide fastener manufacturing method and structure, relates to a double-layer tooth opening slide fastener manufacturing method opening end combination structure, and further includes the double-layer tooth three-in-one opening slide fastener. system method. Background technique [0002] The traditional opening zipper is that the left and right chain belts are respectively provided with a lower file and a latch, and the matching sliders are combined to form an opening zipper. Zippers are generally divided into single-layer tooth zippers and double-layer tooth zippers. Due to the characteristics of high strength and high safety, double-layer tooth zippers have good market demand. In order to make the upper and lower layers of chain teeth have better meshing at the same time, the double-layer tooth zipper needs to be made into a sized opening zipper in ...
