Abstract
Abstract An apparatus for automatically applying finishing stitches around the borders of emblems includes a sewing machine with an automatic needle positioner, a vacuum pickup mechanism for transferring an emblem from a stack thereof to the sewing station, and an emblem guide mechanism including a servomotordriven feed wheel laterally spaced from the sewing machine feed dog and controlled by an emblem edge sensor positioned rearwardly of the needle position. A stitch chain cutter actuated by the sewing machine trails the edge sensor and a stitch chain sensor trails the knife. A network controls the sequence of operations to raise the feed wheel and machine foot piece, transfer an emblem from the stack to the sewing station, to lower the wheel and foot piece, to start the sewing machine to advance the emblem with the last emblem attached thereto by a stitch chain and to apply stitches thereto, to continue the sewing following the sensing of the chain for a predetermined interval to form an overlap of the stitching trailing and leading ends, the connecting chain being cut and the last emblem discharged, to raise the foot piece and speed up the wheel for a predetermined period to swing the sewn emblem from the sewing station while forming a stitch chain, to stop the machine with the needle raised, to raise the feed wheel and to repeat the cycle. The machine is disabled upon thread breakage, improper label positioning and a pressure rise in the vacuum.
