Abstract (en)
[origin: US5129339A] The invention pertains to a blind-stitch sewing machine with a plate-shaped fabric bender to make a sewing material bulge in to the arcuate path of an arc needle. The fabric bender extends in a plane perpendicular to the path of the arc needle and is pivotable to-and-fro in this plane by means of a drive shaft extending perpendicular to this plane. The fabric bender is rotatably supported in a slot of a support assembly projecting from the drive shaft to pivot about an axis parallel to this drive shaft, and furthermore is spring biased away from the drive shaft. To achieve a narrow construction of the fabric bender and of its support assembly, the drive shaft is hollow and a torsion spring is provided to load the fabric bender. The torsion spring is mounted in the borehole of the hollow shaft where adequate space is available to install the spring.
