APPARATUS FOR MELT-FORMING BOTTOM STOP OF SLIDE FASTENER CHAIN |
摘要 |
<p>A bottom stop melt-forming apparatus melt-forms a bottom stop on a continuous slide fastener chain which alternately has a portion in which elements of a thermoplastic synthetic resin material are interlocked with each other and a space portion in which no element is present. The apparatus includes: a device which advances the slide fastener chain; a positioning member having a positioning projection which is adapted to enter the space portion and to engage an element at the rear edge of the space portion; a device which is adapted to sense the engagement between the positioning projection and the element and to stop the advance of the fastener chain; an ultrasonic horn which is disposed in close proximity to the positioning projection; and an anvil which is adapted to clamp and press the fastener chain between the same and the ultrasonic horn after the fastener chain has stopped. The apparatus further includes a groove which is formed on the positioning member and is adapted to slidably guide the anvil.</p> |
