  • Publication number: 20050103245
    Abstract: 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.

  • Publication number: 20040035342
    Abstract: A buttonhole sewing machine for producing buttonhole seams with seam end sections of various shapes in a work piece comprises an input equipment for feeding buttonhole parameters; and a computer for calculating, from the buttonhole parameters, sewing data that determine the respective buttonhole geometry. It further comprises a memory for storing the computed sewing data and a key to be shifted into two key statuses, by means of which to trigger conversion of a buttonhole seam from a position to the left to a position to the right or vice versa, and storage thereof.

  • Publication number: 20030192462
    Abstract: A buttonhole sewing machine comprises work piece clamps with a pneumatically actuated displacement drive for displacement relative to each other of the work piece clamps from an initial position of spread by a length of spread into a final position of spread. Only the first work piece clamp is displaceable relative to the x-y table. The displacement of the first work piece clamp is defined between two stop positions. A control unit stores data for triggering an x drive for reversed displacement of the x-y table by half the given length of spread.

  • Publication number: 20030131770
    Abstract: A CNC controlled buttonhole sewing machine comprises work piece clamps with sliding drives for displacement from an initial position of spread, by a length of spread, into a final position of spread. The sliding drive is an electric positioning motor that is allocated to a work piece clamp. Further provision is made for a control unit with data storage, in which to store data, for displacement of the work piece clamp by a given length of spread.

  • Patent number: 6095066
    Abstract: 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.

  • Patent number: 5647290
    Abstract: 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.

  • Patent number: 5259328
    Abstract: 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.
