Title:
A DEVICE FOR MAKING A STITCHING THREAD ATTACHED WITH A NEEDLE
Document Type and Number:
WIPO Patent Application WO/1997/029692
Kind Code:
A1
Abstract:
The device with a simple, inexpensive structure is designed to make reliable the insertion of a front end of a stitching thread into the stitching thread insertion hole at the rear end of a needle before the needle's rear end is caulked. In the needle caulking device (20), the die supporting members (101, 102) provided with caulking dies (111, 112) that are moved toward and away from each other are mounted with stitching thread guide plates (95, 96), respectively. The stitching thread guide plates (95, 96) are formed with stitching thread guide grooves (95a, 96a). With the caulking dies (111, 112) set at a caulk preparation position where they contact or come close to the rear end of the needle before they actually caulk the needle rear end, the stitching thread guide plates (95, 96) come into contact with or come close to each other so that the stitching thread guide grooves (95a, 96a) form a tapered stitching thread insertion hole.
