Definitions

  • ABSTRACT The device includes a displaceable workpiece clamp on a two-needle sewing machine which is pivotable about a pivot axis coinciding with the'axis of symmetry of the needles into selected angular positions defined by the displacement direction of the clamp and the longitudinal axis of the sewing machine arm shaft, the sewing machine being lockable in adjusted positions.
  • a guide mechanism is provided for folding a braid strip, and a cutting knife is provided to make a longitudinal slit and works between the two needles, the cutting knife being driven by a drive member included in the sewing machine.
  • a set of individually controllable angle knives are provided for making diverging incisions at the ends of the longitudinal slit.
  • the angle knives are mounted separately from the sewing machine for conjoint rotation about respective axes each of which is parallel to the motion path of the associated angle knife, and a crank and link arrangement connects the angle knives to the sewing machine for positive angular adjustment responsive to pivoting of the sewing machine.
  • a support for the cutting knife is mounted separately from the sewing machine and is slidable on fixed guides.
  • the mounting for the cutting knife support is formed with an elongated slot having generally a figure eight configuration, and the cutting knife drive member extends through this slot and is coupled to the cutting knife support, the arrangement providing for relative movement between the cutting knife support and its drive member.
  • the present invention relates to a device for making braid openings extending straightly or obliquely to the hem edge of cutout pieces of garments.
  • the necessary offsetting of the ends of both seams in case of a changed oblique position of the braid opening relative to the hem edge of the cutout piece, while maintaining the equal length of the seams, is obtained by a corresponding control of the individually engageable and disengageable needle bars of the sewing machine.
  • the wedge-shaped cutting blades of the angle knives are mounted in sets of two on respective knife spikes, for pivotal motion about horizontal hinge pins provided near the tips of the spikes. At its free end, each cutting blade is formed with a control arm.
  • the control arms engage into corresponding recesses of triangular swinging arms which are pivotable about the vertical longitudinal axis of the spikes by means of doublemotion control levers, in accordance with a pre selected oblique position of the braid openings.
  • the individual cutting blades are swung, by the control arms which are laterally spaced from the respective axis of rotation of the triangular swinging arms, in mutually opposite directions about their hinge pins fixed near the spike tips so that, in conformity with the oblique position of the braid opening, the two cuts of the angle incision become unequal in length while the depth of penetration of the knife spikes into the workpiece is always the same.
  • the invention is directed to the problem of reducing the costs incurred in the manufacture of complicated devices for making straight and oblique braid openings, and of providing an arrangement permitting, within certain limits, to make braid openings extending at any desired angle to the hem edge of the workpiece.
  • the problem solved by the invention is to appropriately arrange the angle knives and the central knife, and to provide drive connections, between the sewing machine and the angle knives as well as between the sewing machine and the central knife, such that, when the sewing machine is swung into any angular position relative to the advance direction, the angle knives are automatically brought into a corresponding position while the cutting knife mounted in the center remains in its position aligned with the advance direction, irrespective of the angular adjustment of the sewing machine.
  • this problem is solved in that the angle knives are mounted independently of the sewing machine for conjoint pivotal movement about respective axes parallel to their respective paths of motion, and connected to the sewing machine through transmission means effecting positive adjustment of the knives corresponding to the angular adjustment of the sewing machine, and that a support for the cutting knife is mounted separately of the sewing machine for sliding on fixed guide means and is connected to its drive mechanism by coupling means permitting a relative motion between the support of the cutting knife and its drive mechanism.
  • An object of the invention is to provide an improved device for making braid openings in cutout pieces of garments.
  • Another object of the invention is to provide such a device in which the cost of manufacture is greatly reduced.
  • a further object of the invention is to provide such a device including an arrangement permitting the making of braid openings extending at any desired angle to the hem edge of the work piece.

  • Another possibility is to use a control cylinder carrying carns for actuating the corresponding switches and connected to the drive of the sewing machine. Particularities of an electric control may be dispensed with, since such a control is wellknown and does not constitute an object of the present invention.
  • cutting knife 33 is engaged. In operation, cutting knife 33 is projected into slot 35 of throat plate 36 and, during the sewing, cuts central slit 32 extending between the two seams 13 and also the layer of folded braid strip P reposing directly on cutout piece W.
  • the first angle knife 52 is actuated at the respective point by admitting compressed air into the pneumatic cylinder 65, so that angle knife 52, whose carrier 56 is fixed to piston rod 67 of pneumatic cylinder 65, moves through opening in bed plate 20 upwardly and, during this motion, forms the first angle cut 51 in cutout piece W and the layer of folded braid strip P reposing immediately thereon.
  • the finished angle cuts extend from the ends of slit 32 in a V-form up to the ends of the parallel seams 13.
