ABSTRACT:
A production line for manufacturing wooden I-beams wherein a pair of grooved flanges are conveyed along opposite sides of a train of web members and converged so that the web longitudinal edges are inserted into the chord grooves is disclosed. The flanges are each sequentially fed into left and right hand sides of the assembly line through a cam type flange feeder and a resiliently mounted hold-down member automatically orienting the flanges with the flange grooves facing inwardly. A lugged web feeder engages a longitudinal edge of each web to laterally convey same, or random web lengths, into the upstream end of the assembly machine. A web bottom drive engages the web undersides to convey same into contact with the flanges while eliminating overhead clutter to enable easy access to the web and flange members for manual intervention. The web bottom drive and run-up system within the machine is pivotally mounted to left and right hand sides support frames with the pivotal adjustment enabling the height of the web train to be co-elevational with the flange grooves to manufacture wooden I-beams of different thickness. One of the left and right hand support frames is laterally adjustable to impart a corresponding lateral adjustment between the pivotal support frames of the web run-up system to accommodate manufacture of wooden I-beams of different height. As the wooden I-beams exit the assembly machine, they are cut to desired length and then conveyed into a vertically extending wicket curing tower.
