Title:
SEWING MACHINE
Document Type and Number:
WIPO Patent Application WO/2024/029433
Kind Code:
A1
Abstract:
The present invention comprises a needle that holds a needle thread and moves up and down through a throat plate, a looper that holds a looper thread and reciprocates in a space below the throat plate to entangle the looper thread with the needle thread, a retainer that reciprocates in the space below the throat plate and captures the looper thread, and a retainer movement mechanism that changes the movement state of the retainer while transmitting driving force from a drive source to the retainer. For a given period of time during which the retainer is within a given range of positions in the space below the throat plate, the retainer movement mechanism performs the reciprocating motion at a lower speed than that used before and after the given period of time, thereby continuing the state in which the looper yarn is captured.
