Abstract
Method and apparatus for electro-pneumatic control of a stitching machine, operable either in the automatic or semiautomatic mode. Following initiation of a stitching operation through actuation of the present control system, the system internally of itself develops a plurality of interlocks that require the existence of selected conditions for continuation of normal machine operations and which respond to abnormal conditions by precluding machine operation past preselected termination points. Thread conservation is a principal benefit.
