  • Patent number: 8844421
    Abstract: A small glass cutting wheel for producing a scribed predetermined breaking line, wherein the cutting wheel has a radial peripheral line which defines an outer periphery of the wheel and which lies in a main plane of the wheel and at least partially forms a cutting edge. The cutting edge includes cutting teeth which are circumferentially spaced from each other by intermediate tooth spaces and the height and/or circumferential extension of the cutting teeth exceeds a surface roughness. A small glass cutting wheel for manufacturing flat displays can be manufactured with an improved edge quality so that rejected glass plate pieces can be reduced. At least a part or preferably all intermediate tooth spaces include a cutting edge. Preferably, the cutting edges of the intermediate tooth space and the cutting edges of the teeth are arranged approximately in the same main plane of the small wheel.

  • Patent number: 8430289
    Abstract: In the method for cutting a continuously moving glass sheet with an inhomogeneous thickness distribution across the glass sheet, a cutting tool is moved across it at an angle to its travel direction to form a fissure and then the glass sheet is broken along the fissure. To avoid premature breakage in thin regions the applied cutting force is controlled by a controller based on control commands so that the cutting force is decreased when the glass sheet thickness decreases and is increased when it increases. In a preferred embodiment cutting force switchover points are based on an initial measurement of the thickness distribution. In another embodiment the thickness is continuously measured and the applied cutting force is automatically adjusted accordingly, so that the cutting force is greater when the thickness is greater, and vice versa.

    Abstract: A method for improving die-cutting involving first creating a back plate footprint, possessing impressions of the imperfections found in the cutting surface of a die-cutting machine. This method provides die-cutters a simple, inexpensive way to dramatically improve the alignment of die-cutting knives for making cuts. The method uses a malleable material that will readily receive an impression of imperfections of a cutting surface when some pressure is provided, but the material must also be capable of hardening into a useable solid material. The principles of this method may be applied to all die-cutting machines by making a back plate footprint of the die-cutter in question and by properly inserting it back into the chase where the impressions contained therein will press down on the material below it so as to better align the cutting knives of the die being used.

  • Patent number: 7168364
    Abstract: A method and an apparatus are provided for marking a sheet-shaped workpiece using a marking tool. The marking tool is mounted in a punch holder of a punch press and a counter-support is fixed in place on a side opposite of a marking surface of the workpiece to be marked. The surface of the workpiece is marked by displacing the workpiece in its plane while engaging the marking tool with the workpiece. In one form, a support roller provides counter-support. In another form, an elastic element is cooperatively associated with the punch stroke of the punch press to translate an exactly defined contact pressure force between the tool tip and the workpiece to be marked.

  • Patent number: 7156011
    Abstract: A channel cutting tool may include an arbor that connects to a rotating spindle of a machining tool or a similar spinning part of a machining tool. Two slot cutting blades may be fixedly mounted to the arbor. An inner washer may be fixedly mounted on the arbor between the cutting blades and establish the blade spacing. An outer washer may be rotationally mounted to the inner washer with a smaller thickness to facilitate rotation relative to the two cutting blades. The arbor rotates about a longitudinal rotation axis, which also may be the rotation axis for the cutting blades, the inner washer, and the outer washer. The outer washer functions as a depth-limiting safeguard for the channel cutting tool.

  • Patent number: 7059232
    Abstract: A tamper indicating closure comprising a base wall and a peripheral skirt having an internal thread adapted to engage the threads of a container wherein a tamper indicating band is provided on the skirt by a plurality of circumferentially spaced bridges. The band includes portions adapted to engage an annular bead on the container. The bridges are formed by using a primary knife having an interrupted cutting edge to produce a circumferential score in the side wall of the closure leaving spaced connectors or bridges followed by using a secondary knife having a continuous cutting edge to provide a continuous external score line and an accurately dimensional radial thickness of the bridges. In a preferred method and apparatus, the closures engage the successive primary and secondary knives and are moved such that the closures roll relative to the knives.

  • Publication number: 20040154455
    Abstract: A cutoff apparatus includes a blade and an actuator, the actuator being operatively connected to the blade for selectively moving the blade in a rectilinear direction. A cutting block is disposed adjacent the blade, and the cutting block is positioned off-center with respect to a plane defined by the blade's rectilinear movement. A depth control mechanism is utilized for selectively controlling a degree of movement of the blade toward the cutting block. Operation of the actuator selectively causes the blade to move in the rectilinear direction thereby impacting the cutting block to an extent in accordance with the depth control mechanism.

    Abstract: A sheet-like printing medium with easy-separating means which enables one to easily separate the printing medium into separate portions. When an image is formed on the printing medium having easy-separating means disposed inside and entirely along the peripheral edge thereof, a print area is extended slightly to the peripheral edge beyond the easy-separating means. When the width of a non-print area left in the peripheral edge of the print area is separated at a part of the easy-separating means, an image is formed spaced from the sides of each of the non-print areas by a predetermined distance.

  • Patent number: 6626617
    Abstract: In order to further develop a process for making a groove in a board-like workpiece by means of a processing machine, wherein the workpiece is placed on a supporting table of the processing machine aligned essentially horizontal for holding the workpiece in a machining plane and wherein a milling unit held on a machining head of the processing machine is displaced and a groove is thereby milled into a workpiece by means of a milling disk rotating about a drive shaft aligned parallel to the machining plane, in such a manner that the groove can be milled more precisely with a defined groove depth it is suggested in accordance with the invention that the milling unit be guided at right angles to the machining plane by means of a touch roller associated with the milling disk and adapted to roll on the workpiece. In addition, a processing machine for carrying out the process is suggested as well as the use of the processing machine for the milling of a groove into a multilayered or composite material board.

  • Patent number: 6592703
    Abstract: A method and an apparatus for cutting a laminate made of a brittle material and a plastic with a cutting tool is described. The plastic is heated up, thereby lowering its viscosity, at least in the region of a predetermined cutting line. A cutting tool is placed onto the plastic side of the laminate, the loading pressure being adjustable. By moving cutting tool relative to the laminate along the predetermined cutting line, the plastic is severed; at the same time the brittle material is scored, thereby inducing a mechanical stress. If appropriate, the mechanical stress along the cutting line is subsequently increased to exceed the rupture strength of the scored brittle material. A preferred application is the cutting of thin glass or glass-ceramic/plastic laminates.
