  • Publication number: 20140331838
    Abstract: A blade sharpening system for log saw machines is provided. An example multiphase grinding wheel has a grinding face with one or more abrasive concentric rings for sharpening the cutting blade of the log saw machine, and one or more padded concentric rings consisting of fiber padding. Sharpening with the multiphase grinding wheel improves cut quality, increases blade life, removes glues and varnishes from the cutting blade, reduces blade deformation, and hones the edge of the cutting blade. A pneumatic tensioning system uses air bladders to apply a dynamically cushioned pressure between the grinding wheels and the cutting blade. The fiber-padded grinding wheels and the air bladder tensioner provide improved sharpness of the cutting blade and longer life for the mechanical components. The padded grinding wheels decrease fire risk, and the tensioner can be operated remotely, decreasing human injuries common with conventional setup actions near the sharp cutting blade.

    Abstract: The invention relates to a cutting device for cutting continuously conveyed printed products (5). The cutting device has multiple conveying elements (3) which run around a closed path for conveying at least one single printed product (5) or printed product groups (5?). The printed products (5, 5?) are moved along their conveyance path past at least one cutting station (10). In each cutting station, at least one edge of the printed product (5) is cut by knife blades (11, 12) and counter blades (13, 14) in a shear cut. For this shear cut, according to the invention, multiple self-sharpening blades (11, 12) come into cutting engagement with at least one counter blade (13, 14). Alternatively, multiple counter blades (13, 14) come into cutting engagement with at least one self-sharpening blade (11, 12). A significant improvement in edge retention and cutting quality is achieved by means of targeted blade kinematics, blade arrangement, product guidance, and blade geometry.

  • Patent number: 6748836
    Abstract: A sheet material cutting apparatus includes a cutting head and a knife frame rotatably coupled to the cutting head. A blade defining a cutting edge is coupled for reciprocation to the knife frame, as is a primary sharpener for sharpening substantially the entire cutting edge of the blade after it becomes dull from operation. A presser foot having a secondary sharpener mounted thereon, is also coupled to the knife frame for movement between a raised non-working and a lowered working position. The secondary sharpener includes a sharpening member engageable with the cutting edge of the blade via the action of an actuator, for sharpening a portion of the blade's cutting edge between primary sharpening operations.

  • Patent number: 6709319
    Abstract: A sharpener assembly for a food slicer includes a rotatable frame with a sharpening member and a truing member operatively connected for rotation with the frame. The frame is mounted on a food slicer to place the sharpening member and truing member on opposed sides of a slicer knife. The frame is rotated to rotate the sharpening member and the truing member into contact with respective sides of the slicer knife.

  • Patent number: 6644154
    Abstract: The cutting blade of a continuous motion saw is mounted on a skew arm which rotates about an axis which is skewed relative to the path along which the product to be cut is advanced. The blade rotates about an axis which is parallel to the path. The blade orbits in a planetary manner to compensate for the skew angle and to ensure that the blade remains perpendicular to the path. Grinding stones for the blade are mounted radially inwardly of the blade throughout the entire orbit of the blade.

  • Patent number: 6634579
    Abstract: The orbiting knife or knives on a rotary knife holder in a tobacco shredding machine is or are automatically adjusted relative to a sharpening tool in response to signals indicating changes of one or more variable parameters which are indicative of the need for a sharpening of the knife or knives. Such parameters include at least the magnitude of torque which is required to rotate the knife holder but often also the temperature of the mass of condensed tobacco being fed into the range of the knife or knives, the quantity of tobacco per unit length of the mass, the mosture content of tobacco in the mass, the presence and/or the size and/or the nature of foreign matter in the mass, and others.

  • Patent number: 6517298
    Abstract: A method for selectively relieving sharp edges in tools used in die cutting web or sheet-type work material which includes providing a machining apparatus for supporting the tool thereon, where the machining apparatus includes a rotary cutter mounted thereon and moveable relative to the tool. The method also includes providing a controller having machine readable shape data corresponding to at least one of the tools stored therein, and operating the controller to determine, responsive to the stored shape data, locations of edge segments defined by the tool against which the work material will impinge as the work material is advanced onto the tool in a first direction.

  • Patent number: 6375114
    Abstract: During the service of a workstation of a textile machine, a thread, presented to a spool apparatus, is captured by a capture mechanism coordinated with the spool apparatus and conducted to a thread cutting device to be cut through. The thread cutting device is coordinated with a cleaning apparatus, with the help of which the thread cutting device at specified intervals, and/or in dependency of the carrying out of assigned work phases is subjected to cleaning.

  • Patent number: 6360639
    Abstract: A reciprocating knife cutter for performing a cutting operation on sheet material is provided wherein the knife is not limited to reciprocation along a vertical axis. The cutter includes a guide which engages the knife, whereby the knife and guide are constrained to slide relative to one another along the longitudinal axis of the knife. The knife is reciprocated by an eccentric drive mechanism in a plane perpendicular to the drive axis of the mechanism, and the guide is pivotally mounted on the cutter so that the knife and guide remain in engagement as the knife is reciprocated. A sheet material cutting apparatus including such a reciprocating cutter is also provided. The invention also provides a knife sharpener for a cutting apparatus.
