Nail Plate Feeder Patents (Class 470/168)
  • Patent number: 5836826
    Abstract: A machine makes nails having a star-shaped transverse cross-section by sequentially feeding conventional nails into a form roller station defined by a plurality of form rollers that are radially arrayed with respect to a centerline of the nails. Circumferentially spaced notches formed about the periphery of each form roller engage the heads of the conventional nails as the form rollers rotate and pull the nails into forming relation with the form rollers. The notches also prevent formation of the nail heads. A plurality of circumferentially spaced concavities formed in the form rollers prevents forming of the work-hardened points of the nails. The nails are sequentially delivered from a bowl feeder to an indexer that inverts the nails. A pair of rotatably mounted augers transfer the nails from the indexer to a nail-gripping device that holds each nail until its head is engaged by the nail-engaging notch in each of the form rollers.

  • Patent number: 5250008
    Abstract: An apparatus for making elongated headed workpieces having a conveyor device for successively transporting elongated workpieces such as wire pieces transversely to their longitudinal axes from one treatment station into at least one treatment station and including a guided conveyor belt assembly to which the workpieces may be clamped by their circumferential surfaces. Two sections, running together and side by side, of two conveyor belts are guided in such a manner between the stations that they remain in immovable contact on both sides with the transported workpieces. At least one of the two conveyor belts is a toothed belt in which the gaps between the teeth take up the workpieces singly.
