Abstract
In a laminated beam press apparatus a predetermined number of wooden members are conveyed through an adhesive spreader and then are individually transferred laterally into a re-orienting transfer conveyor. The re-orienting transfer conveyor is then moved vertically downward to deposit the collected wooden pieces in a press section. The press platens are closed in order to cure the beam. After curing, the press is open and the re-orienting transfer conveyor then moves vertically upward through the press section, thereby removing the laminated beam.
Claims8
A laminated beam press apparatus comprising:
- means to selectively spread adhesive on the top of a plurality of individual elongated members, in horizontal orientation;
- a vertically movable re-orienting transfer conveyor, comprising:
- means to pick a predetermined number of said individual members from the generally horizontal orientation and transfer them to a substantially vertical side-by-side orientation, and
- means to move the members in their vertical orientation downwardly to a position where they rest atop a substantially horizontally supporting surface;
- a press section having at least two laterally opposed platens extending longitudinally in close proximity to the supporting surface and movable laterally relative to each other in order to bring the members into a pressed relationship;
- and
- means to open the platens after pressing and remove the laminated beam from the press section.
