  • Patent number: 9114655
    Abstract: A binding machine includes a body, an actuator coupled with the body, and a punch mechanism housed in the body for punching a stack of sheets upon actuation of the actuator. The punch mechanism includes a plate including a plurality of punch pins. The punch pins are configured to punch through the stack of sheets during a punch stroke. A shaft is coupled with the actuator such that movement of the actuator causes rotation of the shaft. At least one cam is mounted on the shaft for rotation therewith. The cam is coupled with the plate to drive the plate in a punching direction. The cam includes a cam profile that dictates displacement of the plate in the punching direction relative to rotation of the shaft.

    Abstract: Solder wires are conveyed from insert openings for allowing the solder wires to be inserted toward discharge openings from which the solder wires are discharged and the solder wires project. The projecting wires are cut with first cutting blades and the solder inserted into the insert openings are cut with second cutting blades. This enables fixed cutting stress on a portion of the solder wires to be cut with the first cutting blades and a portion of the solder wires to be cut with the second cutting blades at the same time to prevent deformation of the cut surface of the cut solder wires. Solder columns having a column shape and having a uniform length along a conveying direction thereof can be manufactured.

  • Patent number: 6766721
    Abstract: A bale processor for cutting or dicing a bale or slab of unvulcanized rubber produces small cubes or blocks of a predetermined size and uniform shape for continuous feeding at a predetermined rate into a mixing machine or blender. A bale or slab of feedstock rubber is advanced incrementally along a slider platform and a segment is sliced from the leading end of the bale. After separation, the segment falls onto a receiving panel from which it is transferred by a vacuum pick-up head to a vacuum hold-down table. Multiple slices are then formed through the segment along the X-axis by circular cutting blades of an X-axis cutter head, thereby forming elongated segment strips. Next, multiple slices are formed through the segment strips in the Y-direction by a Y-axis cutter head which includes circular cutter blades that are extendable and retractable along the Y-axis.

    Abstract: A device which trims off the perforated margin strips of printer paper and cuts the paper transversely to separate it into individual pages. The paper which discharges from the printer is drawn around a tension bar and is applied to a toothed belt driven by feed wheels. Cutter wheels act against a grooved roller to cut along the tear lines of the margin strips. A photocell based counting system counts the perforations which pass the photocell to indicate each time the paper is advanced to position one of the transverse fold lines at a cutting station. Then, the paper is stopped and a cutter wire is pulled through the fold line to separate the leading page from the rest of the paper sheet. Each time a new sheet of paper is loaded, a special control circuit assures that the initial advance of the sheet stops with the leading edge of the paper at the cutting station.

  • Patent number: 4606387
    Abstract: In a method and assembly for trimming a stack of veneer sheets, both lengthwise and transverse cutting lines are determined in advance by means of a director light projecting a line. The position data of the determined line are processed by a computer to control the feed to a cutting plane. Alternatively, the cutting lines are marked. The stack is firmly clamped between conveyor belts of a mechanism by which, after the first lengthwise trimming, the stack is turned upside down, after the same procedure for determining the cutting line, fed to the cutting plane. The transverse trimming is effected in similar fashion.

  • Patent number: 4484501
    Abstract: Apparatus for trimming the lateral marginal portions of successive stacks of sheets of multiple unit width and for subdividing the trimmed stacks into stacks of unit width has an advancing unit which moves the stacks stepwise in a direction at right angles to their width, a trimming station where the marginal portions of successive stacks are trimmed, and two or more severing stations which are disposed one after the other, as considered in the direction of advancement of the stacks, and at each of which the width of the stacks is reduced by one unit width as a result of separation of discrete stacks of unit width therefrom. The stacks at the severing stations are moved sideways by the width of a stack of unit width prior to a separating step. The mechanisms at the severing stations employ knives which are aligned with one another, as considered in the direction of advancement of stacks, and are accessible at the outer sides of the respective severing stations.

  • Patent number: 4445407
    Abstract: A trimming apparatus for receiving from a book trimmer the elongated glued book trimmings which have a glued end at one end in the elongated direction and for trimming the glued end. The apparatus comprises a chute for receiving the book trimming and placing the trimming between a chain belt conveyor which has receptacles for those trimmings. The trimmings are moved along the conveyor to and between a pair of rotary cutting blades so that the glued portion of the trimming is cut from the unglued portion of the trimming. The portions are separated so that the glued portions fall into one bin and the clean paper portions fall into a second bin. A related method for separating the glued end of a book trimming from the remainder of the trimming is also disclosed.

  • Patent number: 4441391
    Abstract: Apparatus 30, FIG. 2 for severing an article 12 from a carrier strip 10 and for positioning the severed article is disclosed. The apparatus includes a die 33 having an aperture 32 exiting therethrough from an entrance end 35 to an exit end 36. A ramped shaped wall 37 is located on one surface of the aperture to taper the aperature as it extends from the entrance end to the exit end such that the exit end has a rectangular block "C" shaped opening. A punch 31 in axial alignment with the aperture for entering into and extending through the aperture, has a cavity 43 on one surface to accept ramped shaped wall 37 as punch 31 extends into aperture 32 and to form a block "C" shaped surface on the bottom face 42 of punch 31. When an article 12 is placed between punch 31 and aperture 32 and punch 31 is moved into the aperture, article 12 is severed from carrier strip 10 and is pushed by face 42 into the aperture.

  • Patent number: 4424093
    Abstract: The invention relates to a method and to an apparatus for the production of stamp or photo album leaves with slip-in pockets for the stamps. Two transparent sheets in web form are linearly bonded to one another, and slip-in pockets are stamped out of the bonded sheet material to form double sheet pockets joined along a linear edge. The slip-in pockets are stamped out of the double sheet web by a stamping tool assembly in a predetermined arrangement corresponding to the pocket placement intended for the album leaf, and holds them firmly in this arrangement by a partial vacuum. In the meantime, an adhesive has been applied to the album leaf in the places provided for the slip-in pockets. The album leaf is then brought into contact with the slip-in pockets held fast by partial vacuum on the stamping tool so that the pockets are secured to the album leaf.

  • Patent number: 4253364
    Abstract: An apparatus for withdrawing a continuous band of multi-article skin packages from a skin packing machine includes a clamping device for periodically grasping the band and stepwise withdrawing it from the skin packing machine in a direction of band feed; a first cutter for severing the band parallel to the direction of band feed; and a second cutter for severing the band transversely to the direction of band feed. The two cutters can divide each multi-article skin package into smaller, single-article packages. The apparatus further has a punch for providing hanger holes in the packages simultaneously with the severing operation of the second cutter; a sled carrying the clamping device, the second cutter and the punch back and forth parallel to the direction of band feed. A control intermittently and simultaneously actuates the second cutter and the punch at predeterminable locations when the sled travels against the direction of band feed.
