  • Patent number: 6468024
    Abstract: Disclosed are machines and methods of orienting and stacking a stream of workpieces when it is desirable to stack at lease some of the workpieces in a face-to-face or back-to-back orientation. The apparatus has a receiving assembly for receiving a continuous stream of workpieces. A flipping assembly follows the receiving assembly for selectively flipping selected workpieces onto their opposing faces. Downstream from the flipping assembly, a stacking guide is positioned for guiding the workpieces into stacks for further manual or automated handling.

  • Publication number: 20020100703
    Abstract: The invention is directed to a connector plate packaging system and method of packaging connector plates for storage and transport. Each connector plate has a planar base with a plurality of teeth extending from the front face thereof. The package comprises a tray and a plurality of connector plate pairs. Each connector plate of each pair is arranged tooth-to-tooth such that the teeth extend toward the other connector plate of the pair in a tooth-to-tooth arrangement. The connector plate pairs are arranged back-to-back such that the back face of one of the connector plates of one of the pairs is in parallel abutment with the back face of one of the connector plates of another pair. The plurality of connector plate pairs are disposed in a tray. In one aspect of the invention, the tray and plurality of connector plate pairs are enclosed in wrapping material.
