  • Patent number: 11911925
    Abstract: A method is provided for automatically adjusting a cutting gap of a slicing machine for slicing strand-shaped product calibers from a food product into slices, wherein the slicing machine includes a blade motor for driving a blade about a blade axis, wherein the blade has a peripheral cutting edge which defines a blade plane, and a cutting frame with a counter edge for cooperation with the cutting edge. Under control by a controller and without contact of the blade to the food product to be cut, the method comprises: a) moving the blade along the blade axis in an approach direction to approach the cutting frame until contact with the cutting frame, b) stopping the approach movement of the blade, and c) moving the blade back in a spacing direction by a distance corresponding to a desired size of the cutting gap, measured in a direction of the blade axis.

  • Patent number: 8042478
    Abstract: An automatic panel cutting and edge seaming system includes a series of side edge cutting and seaming assemblies that receive a fabric material and trim and sew seams along the side edges of the fabric material to form a desired width panel. Puller rolls pull the material through the side edge cutting and seaming assemblies and feed the trimmed and seamed fabric material to a cross-cut sewing assembly. After a sufficient length of fabric material has been fed to form a desired size panel, the cross-cut sewing assembly is engaged to cut and seam the end of the panel.

  • Patent number: 8042443
    Abstract: A disc-shaped tool includes a plurality of virtual regions formed such that it is surrounded by two radius lines extending from a rotation center of a disc-shaped base metal and two concentric circles on the base metal disposed around the rotation center. A central angle formed by the two radius lines is equal to or less than 90°, and the number of the virtual regions is 4 to 24. The concentric circle located in a center of an interval of the two concentric circles forming the virtual region is in a range of 0.6 r to 0.8 r with respect to the rotation center of the base metal when a maximum gullet bottom radius of the base metal is r. An overlapping of the virtual regions continuously adjoining each other is in a range of 0° to 12°. A minimum neighborhood distance between the adjoining slits is equal to or more than 0.05 r. A ratio of a length of an arc of the central concentric circle in each virtual region with respect to the interval of the two concentric circles in the virtual region is 3 to 6.

  • Publication number: 20110179932
    Abstract: A circular cutting blade is configured for cutting meat when turned about a rotation axis in a predetermined cutting direction. The cutting blade has a peripheral blade edge defined between the first and second sides and a plurality of circumferentially disposed cutting knives. Each cutting knife includes first and second knife sides and an arcuate knife edge that constitutes a portion of the peripheral blade edge. Each knife edge rises, relative to the rotation axis, between a first blade-edge location corresponding to a minor blade radius and a second blade-edge location corresponding to a major blade radius and further includes beveled primary and secondary knife-edge portions along which the first and second knife sides mutually converge at, respectively, a first bevel angle and a second bevel angle less acute than the first bevel angle.

  • Publication number: 20110162504
    Abstract: A magnet holding jig comprises a platform and first and second holders disposed on opposite sides of the platform. The platform is provided with channels, the holders are comb-shaped to define digits and slits, the channels and the slits being aligned to define guide paths for permitting entry of a cutting tool therein, and the holders are also configured as digitate hooks. The holder hooks are in contact with a rare earth magnet block resting on the platform. The holders are pushed inward at their lower portions so as to elastically deform the digitate hook and move it backward and to bring the hook digits in pressure abutment with the magnet block, thereby holding the magnet block in place on the platform.

  • Publication number: 20110017043
    Abstract: A saw blade assembly has a thin saw plate and a pair of collars, one to each side of the plate. The plate and collars include a center spindle hole, the spindle holes aligning with one another, and a plurality of secondary holes. The secondary holes are used to insert a fastener through the three elements. Alternatively, the thin saw plate is used with two collars that are not identically configured. One collar includes a center bushing having a spindle hole. The center bushing is longer than the first collar is thick and extends outwardly to one side of the collar. The saw plate and a second collar each includes a hole that accommodates the diameter of the center bushing such that the plate and the second collar fit over the bushing. Secondary holes are included to allow for the insertion of fasteners through common holes in the three elements.
