  • Patent number: 11305903
    Abstract: Apparatus and methods of forming boxes from template blanks includes moving the blank forward on a drive line while one or more side panel fingers raise and lower various side panels of the blank in an alternating fashion. One or more holders maintain the side panels in position as the blank moves forward on the drive line. The raised and lowered side panels rigidify various panels from which they extend. The rigidified panels may be less susceptible to bending along false scores that extend transversely across the blank during folding and bending steps of the box forming process.

  • Patent number: 8950049
    Abstract: Fasteners, such as rivets, are fed to a fastener insertion tool (1) via a buffer magazine (5) adjacent to the tool. The buffer is movable with the tool and C-frame between an operative position where fasteners can be inserted int a workpiece and a re-filling position where it is docked at a docking station (13) to reload. Fasteners are delivered to the docking station from a source (14) and held there ready for when the tool docks. Once docked a transfer gat is opened at an interface between the buffer magazine (15) and the docking station (13) and fasteners from the docking station are transferred into the buffer magazine. A fastener insertion cycle is executed while the docking station is refilled with fasteners. A control cycle is used to control the quantity of fasteners loaded into a storage track at the docking station and operates to reduce overfilling of the buffer.

  • Patent number: 6892920
    Abstract: Apparatus is provided for actuating a tag attaching tool of the type which dispenses plastic fasteners from a clip of fasteners in response to the depression of a trigger. Each of the fasteners has a T-bar. The fasteners are dispensed by severing the fastener from the clip and ejecting the T-bar of the fastener through the hollow slotted needle of the tool. The tag attaching tool is actuated in two stages. During the first actuation stage, the trigger of the tool is partially depressed as the tool and an abutment are moved relative to each other such that the lead fastener is severed from the clip of fasteners. During the second actuation stage, the trigger of the tool is depressed completely, as the tool and abutment are moved further toward each other, causing the severed fastener to be ejected from the hollow needle of the attaching tool.

    Abstract: Rivets are delivered from a feed chute to a transfer location and blown through a feed tube to a loading device. The presence of a rivet is sensed both at the transfer location and at the loading device and a fault indicator is operated in the event a rivet sensed and transported from the transfer location does not wind up in the loading device. The operator hits the reset button which blows clean air thru the feed tube in an attempt to free the jammed rivet. In the event this does not occur, the system assumes the operator cleared the jam and loads the next rivet into position to be transferred and continues the cycle.

  • Patent number: 4438724
    Abstract: A grooved passageway surface in a magnetic gas gate, the gas gate adapted to operatively connect two adjacent chambers, in the first chamber of which process gases are introduced for depositing a first layer upon a magnetic substrate and in the second chamber of which process gases are introduced for depositing a second layer atop the first layer. Since it is important to prevent the second chamber gases from contaminating the first chamber gases, a constant pressure differential established between the chambers is employed to provide a substantially unidirectional flow of gases from the first chamber into the second chamber. Magnetic gas gates have been used in the prior art to reduce the size of gas gate passageways by creating a magnetic field which urges the unlayered surface of the substrate toward a wall of the passageway.

  • Patent number: 4372473
    Abstract: A stitching assembly for stitching together sheets of paper, card and similar materials comprises a frame carrying a number of stitching machines each of which includes a stitching head and a clinch block connected together so that each stitching head and its associated clinch block are movable along the frame as a unit. A code bar assembly which is mounted on the frame includes a number of code bars and co-operating means on the stitching machines and the code bars which co-operate to locate the stitching machines at positions along the frame determined by the spacing of the co-operating means along the code bar. The spacing of the co-operating means on each of the code bars is different and the code bar assembly includes means to move the code bars to enable each one of them to be associated with the co-operating means on the stitching machine.

  • Patent number: 4367835
    Abstract: This invention provides improvements in nail feeding control as presented in U.S. Pat. No. 3,273,776. The ratchet system of the reference patent has been improved upon by use of a two-position drum bar which is moved by a cylinder. The latter is activated by a programmer to select nails in accordance with a first predetermined pattern for the top deck of, for example, a pallet, and at the other position a second predetermined pattern of nails is fed for driving into the bottom deck. Any number of stringers may be attached using the one pattern for the top deck and the other pattern for the bottom deck.

  • Patent number: 4323183
    Abstract: The tag-dispensing device is designed for use with a hand-held plastic fastener attacher of the type having a needle for penetrating an article to be tagged and through which a fastener is dispensed. The device includes a support to which the attacher is movably mounted and upon which is situated a stack of tags. A slide is utilized to move a tag along the plane between the stack and a position in alignment with the needle of the attacher. The attacher is mounted to the support by a plate which is movable relative to the support between a position wherein the needle is remote from the plane of slide movement and a position wherein the needle intersects the plane. Slide movement may be accomplished manually or automatically in conjunction with the movement of the attacher by using a mechanical linkage, an electrically driven motor, a solenoid, or a pneumatic cylinder.

  • Patent number: 3994427
    Abstract: An automatic sheet jogging and stapling machine is disclosed and includes a downwardly, sidewardly inclined platform for receiving sheets of paper, and a side wall and bottom release gate that extend upwardly from the platform to define a sheet receiving corner. Longitudinally and laterally movable jogging fingers are provided to align the sheet edges against the release gate and side wall and a stapling head is mounted spaced above the sheet receiving platform to staple the sheets together. The release gate is opened to gravitationally eject the stapled paper. A cam operated control sequentially actuates the longitudinally and laterally movable jogging fingers, the stapling head, and the release gate.
