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.

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.

Abstract: A method of manufacturing a configured cut-out in a sheet of material by arranging a pair of dies to support a sheet of material therebetween, pushing a punch shaft through one die, then through the sheet of material and then through the other die, then retracting the punch shaft to effectuate initiation of a nibbling operation to produce a cut-out in the sheet of material to correspond to a cut-out in a template, which template is traced by a pilot finger during common motion of the template and the sheet of material.
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.
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.

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.
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.
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.
Abstract: An apparatus and method for cutting a piece of pre-shaped carpet to pattern. The apparatus includes a bottom support platen, a common support having depending therefrom, a top pressing platen and vertically-cutting blades. The bottom support platen and the top pressing platen are shaped to conform to the shape of the pre-shaped carpet. The common support is moved vertically down so that the top pressing platen exerts substantial pressure on the carpet, and the common support continues to move down so that the vertically-cutting blades cut the carpet. The common support then moves up, lifting the blades up, followed by the reduction and release of the pressure on the carpet.In a preferred embodiment of the method and apparatus, a peripheral support member and peripheral pressing member are provided to firmly hold the extreme edge of the carpet so that the section of the carpet to be cut is held taut during the cutting operation.
Abstract: To avoid the waste of die-cutting a plurality of circular blanks of identical diameter from rectangular sheet material, the material is formed into non-rectangular sheets of parallelogram trapezoid, or equilateral triangle configuration, which have a predetermined length and width substantially equal to a multiple of the diameter of the circles. The circular dies of a gang-die cutter are juxtaposed in a series of laterally extending rows in parallelism, longitudinally of the die cutter, the rows being at an angle of 60.degree. to the longitudinal edges of the sheets. The sheets and the die pattern thus both are of parallelogram trapezoid, or equilateral triangle, outline.
