Electronic sewing machine |
摘要 |
An electronic sewing machine whose needle bar assembly is made to reciprocate by means of a pair of cooperating solenoids in conjunction with a bobbin driven by a stepping motor to accomplish the sewing. The stepping motor's steps are made variable programmatically by a CPU attached to the machine such that the tightness of a stitch may be controlled. Additionally, the machine may be programmed to deliver a defined number of stitches in a defined number of stitch runs, position the needle up or down, report a variety of accounting and maintenance data and can be taught to perform a variety of sewing runs.
