Abstract: A lumber cutting and delivery system for use in assembling trusses on a truss table includes a saw for cutting a piece of material into pieces of a truss. A trunk conveyor system receives the pieces cut from the saw. The trunk conveyor system has a first conveying element to transport the pieces over a distance in a travel direction and an ejector for discharging the pieces from the first conveying element in a first discharge direction. A branch conveyor system is configured to receive the pieces discharged from the trunk conveyor system in the first discharge direction. The branch conveyor system has a main conveying element to transport the pieces.

Abstract: A lumber cutting and delivery system for use in assembling trusses on a truss table includes a saw configured to receive a piece of material therein. The saw is configured to cut the piece of material into one or more pieces and at different lengths and angles so that at least some of the one or more pieces are the components of at least one truss. A trunk conveyor system is positioned to receive the one or more pieces cut from the saw. The trunk conveyor system has a first conveying element to transport the one or more pieces over a distance in a travel direction and an ejector configured to discharge the one or more pieces from the first conveying element in a first discharge direction. A branch conveyor system is configured to receive the one or more pieces discharged from the trunk conveyor system in the first discharge direction. The branch conveyor system has a main conveying element to transport the one or more pieces.

Abstract: An adjustable leg for a truss fabrication system used in mass production of trusses. The system has a truss set-up table and a gantry press movable relative to the truss set-up table for pressing nailing plates into truss members. The table is supported on legs which are readily adjustable in height even after installation of the table to maintain the table in a level orientation.

Abstract: A truss fabrication system for fabricating trusses includes a table, a gantry press and an obstruction detection device. A top of the table receives truss components arranged with at least some connector plates engaging at least some of the truss members. The gantry press includes a gantry mounted for movement along a path relative to the table for pressing the connectors into the truss components for joining the truss members together. An obstruction detection device is mounted on the gantry for detecting obstructions in the path of the gantry. The detection device defines a vertical detection plane located a predetermined distance from the gantry and is adapted to detect the presence of all obstructions entering the plane at substantially the same time for stopping movement of the gantry.
