Abstract (en)
[origin: DE102004012822B3] A chain stitch sewing machine has a sewing head (10) that moves parallel to the horizontal sewing plane (12) with a needle rod (20), needle (22) and needle drive (24) operating at right angles to the plane (12). The upright thread trap (26) operates in conjunction with a powered thread puller (36) with a hooked (42) horizontal arm (40). The arm motion is controlled such that when close to the thread trap in the upper position, the arm engages with a hanging thread loop after the hook has opened.
