囲第１項記載のミシンのバンドループ弛め装置。[Claims for Utility Model Registration] [1] A feeder 16 that is relatively moved in a direction intersecting the vertical movement path of the sewing needle 24, and a presser arm 20 provided on the feeder 16 that is directed toward the bed surface of the sewing machine. A presser foot 22 is provided which can be raised and lowered to press the work cloth 70 near the needle drop position of the sewing needle 24 toward the bed surface, and a cloth presser foot 22 is provided to press the work cloth 70 near the needle drop position of the sewing needle 24 toward the bed surface. a cloth moving member 36 that horizontally reciprocates the work cloth 70 substantially parallel to the bed surface and is movable up and down toward the bed surface in order to arrange the work cloth 70 at each of the 24 needle drop positions;
Gripping means 74, 7 capable of gripping and releasing the band loop 72 and horizontally reciprocating beyond the needle drop position of the sewing needle 24 substantially parallel to the bed surface.
6, in which a regulating member 86 that can freely appear and retract with respect to the horizontal movement locus of the cloth moving member 36 is disposed on at least one of the feed table 16 and the presser arm 20, and always The regulating member 86 is removed from the horizontal movement locus of the cloth moving member 36, and the cloth moving member 36
When the sewing at one end of the band loop 72 is completed, the gripping means 74 and 76 hold the free end of the band loop 72 in order to perform sewing at the other end. After folding and moving, the regulating member 8
6 facing the horizontal movement locus of the cloth moving member 36, and the movement of the cloth moving member 36 is restricted at a predetermined distance to form slack in the band loop 72. device. [2] The regulating member is configured as a stop lever 86 rotatably pivoted vertically to the feed bar 16 or the presser arm 20, and the stop lever 86
One end portion 86a is connected to the piston rod 82 of the cylinder 81, and the other end portion 86b is connected to the horizontal movement locus of the protrusion piece 52a protruding from the connecting body 52 that supports the cloth moving member 36 by rotation of the lever 86. A band loop loosening device for a sewing machine according to claim 1, which is configured to be able to prevent the movement of the protruding piece 52a at a predetermined distance when viewed from above.
