Abstract
A residual thread chain back tacking device for stitching a residual thread chain in the proper position of a succeeding sewn cloth material has a thread chain cutting device which initially cuts most of the thread chain off, and then blows the remaining thread chain in the back tacking direction and horizontally. A thread chain suction pipe moves adjacent the back tacking position and sucks the remainder of the thread chain thereinto and holds it by means of a thread chain press cylinder while back tacking is completed. An air nozzle then blows the remaining thread chain against a cutter, and the suction in the thread chain suction pipe sucks the cut-off end away.
