Title: Needle thread vibration preventing mechanism
Inventor: WATABE MITSUO
IPC: D05B45/00
Filed: 1990-01-25
Abstract: PURPOSE:To prevent a needle thread from being vibrated when a rotary hook catches the loop of the needle thread, to form stitches with proper twist return and to use a sewing machine for a long period by crimping the needle thread by a crimping means when catching the needle thread loop by the rotary hook at least for each stitch and releasing the needle thread when supplying and tightening the needle thread. CONSTITUTION:A needle thread 1 is passed through a through-hole 11c on an outside plate 11b of a crimper 11 and perpendicularly hung down between the outside plate 11b and an inside plate 11a of an elastic material. In the state of positioning a sewing needle at an upper dead point, crossing needle and bobbin threads by the rotary hook and tightening up the needle thread by a balance, a ball object 8 is housed in a fixed shaft 6 by an outer pipe 7. When the needle thread forms the loop in the lower direction of an object to be sewn and the rotary hood catches this loop, the ball object 8 protrudes from an engaging hole 7a of the outer pipe 7 by the energization of a spring 9 and the inside plate 11a is pushed toward the outside plate 11b. Then the needle thread 1 is pushed so as to crimped between the inside and outside plates 11a and 11b of the crimper 11. The needle thread is pressed in such a way while the outer pipe 7 is moved for a length L of the longitudinal opening of the engaging hole 7a.
