ABSTRACT:
A sewing system (10) includes a tension adjustment spindle assembly (30) constructed and arranged to move a spindle (26) laterally toward and away from a sewing head (16) of the sewing machine to adjust the tension in the looped end of a work piece (28). A tension roller (70) engages a bottom run (29) of the work piece (28), so that when proper tension is applied to the work piece at the beginning of the cycle of operation by the lateral shifting of the tension adjustment spindle assembly (30), a proximity switch (88) detects the upward movement of a tension arm (72) and initiates the operation of the sewing system. As the sewing system operates and the work piece tends to become longer because of the penetration of the needles and the insertion of stitches between the yarns of the work piece, and temporary stretching associated with the handling of the work piece, the tension roller (70) moves downwardly into the lower run of the work piece to constantly apply a predetermined downward tension force against the bottom run of the work piece to maintain a constant tension force on the work piece.
