Sewing machine control mechanism |
摘要 |
The stitch-forming instrumentalities of a sewing machine are subject to small mechanical operational errors due to play in the motion-transmitting connections. The invention overcomes this problem by providing two springs which are respectively connected to a transmission element coupled to a driven mechanism of the machine, and to a drive. The two springs counterbalance one another with respect to the drive.
