Embodiment Construction

[0036] Exemplary embodiments of the present invention will be specifically described below with reference to the accompanying drawings.

[0037] figure 1 Shown is a zipper chain 3 to which reinforcing tape pieces 1 and 2 are bonded by the welding method of the present invention. The void portion 5 from which the tooth 4 has been removed is formed in the zipper unit along the length direction of the zipper chain 3, such as figure 1 shown. Reinforcing tape pieces 1 and 2 enclose the peripheries of core portions 6a and 7a formed along opposite tape side edges of the fastener tapes 6 and 7 exposed in the void portion 5, and the reinforcing tape pieces 1 and 2 are welded and bonded to the back of each main body belt portion 6b and 7b over the entire surface.

[0038] In this embodiment, the reinforcing tape sheets 1 and 2 are of a laminated structure in which a relatively low-melting synthetic resin layer is provided or coated on the welding surface side of a braided tape or a s...

Abstract

In order to weld a reinforcing tape piece (1, 2) formed of a synthetic resin to a separable bottom stop a separable bottom stop attachment portion of a slide fastener chain (3) by ultrasonic heating over a core portion (6a, 7a) and a main tape portion (6b, 7b) in a fastener tape (6, 7), a welding time and/or an amplitude which are/is suitable for welding the reinforcing tape piece (1, 2) to the core portion (6a, 7a) and the vicinity of the core portion, and a welding time and/or an amplitude which are/is suitable for welding the reinforcing tape piece (1, 2) to the main tape portion (6b, 7b) are preset respectively. The welding of the reinforcing tape piece (1, 2) to the core portion (6a, 7a) and the vicinity of the core portion and the welding of the reinforcing tape piece to the main tape portion (6b, 7b) are carried out in two stages in accordance with the welding time or the amplitude which is set.

Description

technical field [0001] The present invention relates to a method and a device for welding, by means of ultrasonic heating, a reinforcement strip formed of synthetic resin to a portion where a detachable bottom stopper of a zipper chain is mounted to the core of the zipper tape and on the body belt part. Background technique [0002] Void portions (parts without teeth) for mounting the upper stopper and the detachable bottom stopper are intermittently formed in the zipper chain of the zipper with the detachable bottom stopper. The detachable bottom stopper is mounted on the void portion. Before the detachable bottom stopper is installed, a reinforcing tape sheet formed of synthetic resin is generally adhered to the detachable stopper installation portion of the zipper chain for reinforcement. [0003] The reinforcing tape pieces are bonded in a structure capable of holding the opposite tape side edges of the void portion of the fastener chain, and the core cord is woven int...
