    摘要: A cutting device for a sewing system having a work table, and a material clamp on the work table for transporting sewing material to a cutting point. The cutting device includes two wedge-shaped knives arranged at the cutting point, for producing gusset cuts in the material, and an elongated opening in the work table for allowing the wedge-shaped knives to pass through the work table to cut the material. The cutting device further includes a clamping device for clamping the material at the cutting point so as to increase the tension in the material and thereby increase the controllability of the location at which the wedge-shaped knives make the gusset cuts. Preferably the camping device which includes two transversely movable clamp halves tightens the sewing material transverse to the direction of transport of the sewing material. Further, a slide plate attached to the surface of the work table includes shoulders or tensioning beads for tensioning the material. Because the material is held taut before the gusset cuts are made, the cuts can be made at well defined points, even in the case of very fine material.

    摘要: A thread-cutting mechanism for a sewing machine (2), especially an eyelet-buttonhole sewing machine with a moving blade (12 or 12") and a stationary blade (16). The moving blade travels back and forth in a groove (19) in a plate (1) with an aperture for the needle to pass through while it is producing a stitch. The needle-aperture plate comprises at least a top (11 or 11") and a bottom (10 or 10"). The moving blade is entirely accommodated between the top and the bottom of the plate. The stationary blade is part of the top.

    摘要: A buttonhole sewing machine comprises a top arm (1) with a needle (6) movable in up and down reciprocation and a base plate (2). A buttonhole cutting device (13) is provided, having a knife (36) which is disposed on the base plate (2) and comprises a straight cutting edge (37) that extends in the y direction and an eye cutting edge (38). A cutting block (15) cooperates with the knife (36). The knife (36) and the cutting block (15) are motor-adjustable one in relation to the other in the y direction.

    摘要: A sewing machine having a table, driven in two directions by two motors and accommodating material to be sewn, sewing tools, and a cutting device for producing a buttonhole in the material to be sewn. The buttonhole is provided with an incision and is bounded by zigzag stitches of a buttonhole bead, running around the incision. The incision is produced either before or after the sewing of the buttonhole bead. The sewing tools include a needle bar, which is driven up and down and also oscillates in the horizontal direction, and a needle, which is provided at the bottom end of the needle bar and interacts with a looper mounted in the base plate. The sewing tools are drivable in a rotatable manner by a third motor. The sewing machine has a control device, from which various buttonhole shapes stored therein can be retrieved, a device for switching from the pre-cutting mode to the post-cutting mode, and a needle-oscillating device driven by a fourth motor and producing the zigzag stitches. The control device also controls the oscillating motion of the needle bar in order to produce the intermediate material, required in the post-cutting mode, within the buttonhole bead.
