Problems solved by technology
[0004] However, in the above-mentioned curve sewing machine in which the pulling-out amount of the cloth to be sewn is different from the plurality of pullers 71, 72 arranged side by side at predetermined intervals in a direction substantially perpendicular to the direction in which the cloth to be sewn is drawn out, Since the pulling-out direction of the sewn cloth is a straight line parallel to the cloth conveying direction A, even if the pulling-out amount of each sewn cloth of a plurality of pullers 71, 72 is changed, the curve-shaped curve is sometimes lacking. The smoothness and reliability of drawing the cloth 73 to be sewn 73 along the curve of the cloth to be sewn 73 have problems such as wrinkles on the cloth to be sewn 73

The present invention provides a curve sewing machine which can smoothly and surely pull out a curved strap along the curve of the curved strap. A driving puller 6 is installed under a tilt so that the external end 6b side in the axial direction of the driving puller 6 which pulls out the external circular arc edge side of the curved strap may be leaned to the rear side more than the internal end6a side in the axial direction of the driving puller 6 which pulls out the internal circular arc edge side of the curved strap.
Description
technical field [0001] The present invention relates to a puller device (プ-ラ-device) of a curve sewing machine (カ一ブいいでいいいすン), and more specifically relates to sewing and cutting into a curved shape, for example, on the fabric to be sewn such as the front and rear body of low-rise jeans. The puller device for the curved belt of the curve sewing machine. Background technique [0002] Such as Figure 15 , Figure 16 As shown, in the puller device of the conventional curve sewing machine, for example, a plurality of pullers 71, 72 are arranged in parallel at predetermined intervals behind the cloth push rack 70 (downstream side in the cloth feeding direction A). The puller 71, 72 is used to pull out the curved sewn cloth 73 from the cloth pushing rack 70 in a direction substantially perpendicular to the pulling out direction of the cloth to be sewn, so that each puller 71, 72 is The amount of drawing of the sewing cloth varies, and curved surface sewing can be performed on the...
