  • Patent number: 4293086
    Abstract: This apparatus separates downturned flaps of paperboard cases, which flaps are joined by tabs and lying over sides of the case, without requiring the use of a knife or other sharp instrument for cutting. The apparatus has a conveyor for moving the case through the apparatus. There is a first device for engaging one of the flaps. A first thrust device is positioned proximate to the conveyor and connected to the flap engaging device for moving it against the side of the case over which the one of the flaps lies, and below the flap. There is a device operatively coupled to the flap engaging device for moving it along the side of the case until at least a portion of the flap engaging device extends between the flap and the side against which it lies. A device for retracting the flap engaging device is connected thereto and does so with sufficient force to break the tab joining the flap to another one of the flaps of the case. The flap engaging device is preferably frustum shaped.

  • Patent number: 4235357
    Abstract: A machine and method for subdividing into individual substrates a wafer which is prescored with a pattern of intersecting score lines defining the substrates. The wafer is progressively directed over a first wafer-engaging surface substantially paralleling one set of score lines, and this surface cooperates during a breaking operation to impart a localized force at a score line in the set. The wafer is halted during the breaking operation, after which the broken-off portion is directed over a second wafer-engaging surface substantially paralleling the other set of score lines. This second surface cooperates, during a substrate breaking operation, to apply a localized force adjacent a score line of the other set. The broken-off portion is halted during this latter breaking operation at which a substrate is separated from the broken-off portion of the wafer.

    Abstract: Method and apparatus for producing a concrete panel having a fractured rib finish is disclosed. A quantity of relatively low slump concrete mixture is cast upon a pallet in the form of a panel and is extruded to define projecting ribs and channels. The casting is permitted to harden until the concrete becomes rigid but not completely set. Thereafter an array of wedges secured to a carriage assembly is drawn along the length of the panel with each wedge disposed in shearing engagement with edge portions of an adjacent pair of ribs. Each wedge includes a shoulder portion wider than the channel for shearing and forcibly displacing portions of the ribs as the wedge is drawn through the channel. Means are provided for propelling the carriage assembly along the length of the panel and in a direction parallel to the orientation of the ribs. A concrete panel having a fractured rib finish produced by the method of the invention is similar in appearance to a concrete panel having a manually hammered rib finish.

  • Patent number: 4084569
    Abstract: The invention relates to tile cutters and provides a tool for cutting glass and ceramic tiles. The tool can be used both to guide a scriber for scoring the surface of the tile and also to provide the necessary bending stress to snap the tile along the score line. The tool comprises a base member and an arm hinged thereto, a ridge being formed on the top of the base member. The arm includes a slot for guiding the scriber and at least one pair of shoulders located on either side of the slot. The slot is held parallel to the ridge so that the shoulders are located on either side of the ridge. When pressure is applied to the arm with a tile resting on the base member, bending stress is applied to the tile by the ridge acting on one side of the tile and the two shoulders acting on the other side of the tile.

  • Patent number: 4068788
    Abstract: A machine for separating a sheet of brittle material, for example a semiconductor wafer, into a plurality of pellets is disclosed. The pellets are defined by a plurality of intersecting scribed lines on the sheet. The machine includes a member for applying a shear force to an edge of the sheet whereby the maximum bending moment is applied at a preselected scribe line. The machine is particularly applicable for use with those semiconductor wafers which have a solder coating on both sides.

  • Patent number: 4059036
    Abstract: An internal member for supporting a hollow body during shearing in the form of a close-fitting solid body. The body comprises at least portions meeting in the shearing plane and each portion including at least one split ring having a single gap in its periphery to allow it to expand to fit the hollow body. Expansion may be effected by axial movement of frusto-conical plugs corresponding to and co-operating with frusto-conical inner surface in the rings. Each ring may either comprise a single component, preferably notched on its inner face to increase flexibility, or be in the form of a thin split cylindrical shell surrounding a plurality of inner segments.

  • Patent number: 4049167
    Abstract: A process for automatically removing edge portions from a glass sheet comprises scoring a line of cut on a first surface of the sheet between the edge portion and the remainder of the sheet, hammering the second surface of the sheet along a path opposite the score line to initiate breakage and applying a bending force transverse to this line to the sheet at a predetermined distance from one of its ends to initiate breakage. The process is applicable to long ribbons of glass or to glass volumes having a given length and edge portions of inferior quality may be removed simultaneously from both sides of the sheet.

  • Patent number: 4046300
    Abstract: A glass pattern breaking apparatus having a press roll which is rollably movable across a prescored glass bracket supported upon an aligned template for breaking out the prescored pattern. The press roll is provided with an elongated rigid core shaft covered by a pliable resilient body, and its ends are journalled in freely vertically movable slide mechanisms so that its weight may freely bear against the glass bracket. The core shaft may be hollow so that it can be filled with water or granular material whereby its weight can be changed to break out patterns from glass brackets of different thicknesses.

  • Patent number: 4041847
    Abstract: The present apparatus is constructed for separating previously punched out workpieces from the surrounding waste material, for example, punched-out carton shapes. Preferably, the workpieces are arranged in a stack supported on a worktable. Power driven break-out tool means are located for up and down movement, as well as for lateral back and forth movement above the worktable. If desired, power driven push out means are arranged below the worktable with a push rail extending through a respective channel in the worktable. The break-out tool means and the push rail are arranged to be effective on a stack of workpieces on opposite sides and at opposite ends. The break-out tool and/or the push rail apply a levering action to the workpieces to break any lands or bridges which prior to such levering action connect the workpiece proper to the surrounding waste material.
