A folding mechanism, for a braid strip, is supported on a table plate, in which there is installed a tow-needle sewing machine having a cutting knife working between the needles, with the folding mechanism being inclined downwardly toward the stitch forming area of the sewing machine. Folding of the braid strip is effected by a shape bar, having an inverted T-shape, adapted to be lowered into a folding groove, in a baseplate of the folding mechanism to fold the braid strip so that its borders extend upwardly. Clamping bars are displaceable parallel to the stem of the shape bar, on opposite sides thereof, to clamp and fold the braid strip around the shape bar. The shape bar is vertically displaceable on a support which is pivotal about an axis parallel to the arm shaft of the sewing machine, between an initial position in which it is aligned with the folding cavity or groove, and a transfer position, aligned with the direction of displacement of a work clamp to deliver the braid strip, and a flap, if one is provided, to the work clamp.
In a device for manufacturing braided openings in cuts of articles of clothing, of the type comprising a folding mechanism, for a braid strip, mounted at a location spaced from the stitch forming area of a two-needle sewing machine installed in a table plate and having an arm shaft, a work clamp displaceable relative to the stitch forming area, and a cutting knife working between the needles, with folding of a braid strip being effected by a shape bar, having an inverted T-shape, adapted to be lowered into a folding groove, and by folding slides mounted for movement toward the shape bar to fold a braid strip about the shape bar, and further comprising a work clamp by which a cut of clothing and, if provided, a flap to be placed in contact with a folded braid strip, are received and fed to the stitch forming area:
