ABSTRACT:
In an automatic sewing apparatus, a relay controlled by a backstitch control switch de-energizes a presser foot solenoid to raise the presser foot during backstitching to prevent damage that would result from the presser foot striking a pallet holding a workpiece. A switch, adapted to be actuated by the pallet, disables the operation of the sewing apparatus until the pallet is in a predetermined aligned position with respect to a support carriage which moves the pallet in a predetermined pattern with respect to the sewing head.
