ABSTRACT:
The disclosed invention describes an automatic sewing machine having a linear compensating system for moving a workholder relative to a fixed point. The driving power for the workholder is provided by a pair of stepping motors, each of whose mechanical output is operably connected by the linear compensating system to the workholder. A mechanical feed back means is associated with the system so that the workholder may be moved in a coordinate system which has been modified so that the movement of the workholder relative to the needle closely approximates a rectangular coordinate system.
