Embodiment Construction

[0070] Such as Figure 1 to Figure 4 As shown, the metal wire W for the fastener element is intermittently fed into the metal wire material W for the fastener element by the conveying device for the metal wire for the fastener element, which is not shown, to the forming and embedding part 1 of the fastener element of the zipper fastener stringer continuous manufacturing machine. The supply device of the fastener tape sends out the fastener stringer S, thereby supplying the fastener tape T intermittently.

[0071] Chain teeth with metal wire W such as Figure 5 Shown is a long bar, and includes: a prism-shaped head WH having a thickness a and a width b, and a pair of legs provided on both sides in the width direction of one end of the head WH in the thickness direction facing the thickness direction WL has a groove WO between one end in the thickness direction of the head WH and the pair of legs WL, and has a substantially Y-shaped cross section.

[0072] The shaped embedded ...

Abstract

Provided is an element head-forming device for a continuous fastener stringer-manufacturing machine, the device being capable of detecting malfunctions with a sensor when press-forming the element material and stopping the continuous fastener stringer-manufacturing machine and of using a sensor with a short measurement distance. The element-forming device is configured so that when press-forming the head (WH) of an element material (WA) using a forming die (4) and a forming punch (5), the leg section (WH) of the element material (WA) is pressed against the forming die (4) by bringing a pressing punch (6), which is biased downward by a plate spring (7), into contact with the leg section (WH) and deforming the plate spring (7) upward. The element-forming device is configured so that: a sensor (20) is provided below the plate spring (7); the sensor (20) detects the distance between the sensor and the plate spring (7) in the vertical direction; and the continuous fastener stringer-manufacturing machine is stopped when a malfunction is detected as a result of the detected distance in the vertical direction differing from the normal distance in the vertical direction. Because the sensor (20) is provided below the plate spring (7), the distance between the sensor (20) and the plate spring (7) is reduced and a sensor with a short measurement distance can be used.

Description

technical field [0001] The present invention relates to a fastener element head forming device in a fastener element forming and inserting part of a zipper fastener stringer continuous manufacturing machine. The fastener element head forming device press-forms the head of a fastener element raw material to form a fastener element . Background technique [0002] Conventionally, as a fastener stringer continuous manufacturing machine, as disclosed in Patent Document 1, it is well known that it includes: an element forming and inserting part, and a metal wire for an element that intermittently transfers a metal wire for an element to the forming and inserting part. A conveyor, a fastener stringer supply device that intermittently feeds the fastener stringer toward the molding fitting portion by feeding out the fastener stringer string, and the like. [0003] The metal wire material for fastener elements is a metal wire material formed by passing a long metal wire material with...
