Abstract:
A plurality of wood truss members and metal connector plates are assembled on a relatively flat conveyor surface and are transported to a first pressing station having two pairs of pressing rollers for partially embedding the connector plates into the wood members. The truss is then moved to a second pressing station having another pair of pressing rollers, where the plates are substantially completely embedded into the wood members. All of the rollers have substantially the same diameter and preferably have a diameter of at least ten inches to reduce the "rocking action" on the ends of the plates, particularly during the initial stages of the pressing operation. A plurality of guide rails are disposed beneath the conveyor surface for journally supporting the conveyor surface and the truss. At least one of the rails extends substantially beyond the first pressing station to maintain the alignment of the conveyor surface and the truss as they are moved past the first pressing station toward the second pressing station.
