  • Patent number: 8383196
    Abstract: In a method in which a cut line is formed on one surface of a planar glass material, and the cut line is allowed to extend in the thickness direction of the glass material, thereby cutting a glass substrate from the glass material, the cut line is selectively formed on a surface having relatively small surface waviness out of two opposing surfaces of the glass material. In the case of a glass material formed into a planar shape on a molten metal, the surface which has come into contact with the molten metal is selected as the surface having relatively small surface waviness. When a disk-shaped glass substrate is cut from the glass material, cutting is performed under conditions where either one of the thickness and the radius of the glass material and the maximum height of surface waviness of the glass material satisfy a predetermined relationship.

  • Patent number: 4681000
    Abstract: Method for cutting food materials having predetermined depths defined by a proximal surface and a remote surface, into a desired, continuous, closed configuration. A food material is selected having a predetermined depth. The desired configuration is cut into the food material by inserting therein at the proximal surface blade means having a cutting edge defining at least the exterior outline of the desired, continuous, closed configuration, while maintaining the cutting edge of the inserted blade means spaced from the remote end of the food material. The blade means is then removed from the food material while leaving the cut configuration substantially intact in the food material. Removal from the food material of the desired cut configuration when the blade means is removed is prevented by avoiding excessive compression of the food material when the blade means is inserted in the food material.

  • Patent number: 4549454
    Abstract: A strip of tape is cut at intervals into precise cut lengths equal in length to that of a desired label of non-rectangular shape. The cut lengths of tape are positioned in exact alignment with a punch of a punch cutting assembly for punching out the label and the punched label is separated from waste about the rim of the label for delivery free of the waste. The cut lengths are transferred to a transfer drum periphery and held momentarily under vacuum pressure which vacuum pressure is released to allow the cut lengths to shift circumferentially about the periphery of the transfer drum against a stop to accurately locate the cut lengths prior to further transfer to the punch cutting assembly.

  • Patent number: 4463637
    Abstract: A forging (A) is received in a split ring (B) which provides peripheral support to a forging peripheral wall (14) and an upper peripheral flange (16). The forging and the split ring are supported by a nest member assembly (C) as a trimming assembly (D) moves longitudinally to trim the forging flange and a forging bore (10). A punch (74) with a hardened cutting edge (80) moves axially through the forging bore and interacts with a nesting assembly cutting edge (60) to trim the bore. Concurrently, a trim die (90) having a cutting edge (96) interacts with a split die cutting edge (36) trimming the upper flange. The split ring restrains a central portion of the forging from puffing peripherally outward in response to the punch being urged therethrough. The interaction of the trim die and the split ring inhibits the upper part of the forging adjacent the upper flange from being drawn in toward the forging bore by the interaction between the punch and forging.

  • Patent number: 4429603
    Abstract: A rotary envelope machine blank cutter is provided with laterally adjustable, independent frame units for each meshing set of knife rolls for changing the depth of a side cut into a blank for envelope size and style production changes. The rotational and axial meshing of hard and soft knives respective to a single knife roll set is adjusted without disturbing the roll mount of either knife. Changes in envelope length or style are accommodated by the mechanical capacity to adjust the rotational cut timing between the knife roll sets of a two-set unit and also between respective cutting units of two or more two-set units. As in the case of lateral cut adjustments, knife roll mounts are undisturbed by rotational timing adjustments. Consequently, the machine may be quickly and accurately changed for production runs of any of several envelope style and several sizes respective to each style: all adjustments being made without disturbing the knife profile mesh of any knife set.

  • Patent number: 4375759
    Abstract: A pair of continuously driven pull rolls of stock puller supported on a table having a longitudinal bed engage a web of the stock material to continuously unreel the stock material from a coil. The pull rolls are rotated by a drive shaft that is coupled to an input shaft of a feed roll unit. The input shaft is continuously rotated by a pulley-belt drive connection from a common power shaft. Continuous rotation of the input shaft is converted to intermittent rotation of a feed roll that intermittently advances the stock material to a stock material forming device, such as a material stamping or punching unit followed by a material cutting unit. The stamping and cutting units also include input shafts that are drivingly connected by pulleys and continuous belts to the common power shaft. The common power shaft is continuously rotated by a pulley-belt drive connection from an output shaft of a variable speed DC motor supported by the table.

  • Patent number: 4285754
    Abstract: An arrangement for fabricating planar elements which may be stacked for producing predetermined surfaces and bodies. The planar elements have cross-sections corresponding to respective cross-sections of the surface to be constructed. The planar elements are formed by cutting them from plate-shaped material or sheet metal, and the cut-out elements are held to the parent sheet or plate material by tabs. The planar elements are cut successively from the sheet or plate-shaped material at spaced intervals. The cutting action is such as to leave the tabs for holding the planar elements in place. Registration holes are punched about the planar element, so that these may be readily stacked relative to each other, as required to form the surface to be constructed. Sprocket holes are also punched in the sheet material to advance the material along a processing path at which the various processing stations are located.

  • Patent number: 4128320
    Abstract: A method of producing stereoscopic film from standard 35 mm film is described in which the standard 35 mm is longitudinally cut in half. Selected sprocket holes in each half are enlarged to provide a series of locating holes at regular intervals along the film. Each locating hole enables a corresponding pair of stereoscopic film frames on the film to be located in a viewing position. Also described is a viewer for viewing the stereoscopic films. The viewer incorporates a locating finger which engages each locating hole in turn to locate and hold the film steady while viewing. The viewer includes a reciprocating drive means for driving the film. The locating finger is withdrawn from a locating hole when the drive means performs its forward stroke and the forward stroke is limited when the finger engages the next hole. The finger remains engaged with the next locating hole during the return stroke of the drive means thereby preventing any inadvertant movement of the film during the return stroke.
