Abstract

An appts. is claimed for the movement of the fabric through an automatic and programme-controlled sewing machine, with a workpiece holder with two separate lightweight arms each provided with their own drive linkages and static step motors to move them in dividually according to the required positioning co-ordinates of the workpiece holder. The control signals for the motors are generated by a data store by a programmed semi-conductor store circuit, with data feeds, so that control instruction signals are derived from information read successively from at least two store units. The design gives a low moving mass to the workpiece holder, allowing high acceleration and braking forces in positioning the fabric under the sewing machine needle, under programmed control, for the sewing of patterns, monogrammed, buttonholes and similar sewing applications.
