a woodworking machine for the fabrication of panels of various sizes by gluing together planed or sometimes unplaned wooden beams, edgings, or scraps of boards. A distinction is made between static and continuous panel-gluing machines.
A static panel-gluing machine has supports on which clamping mechanisms are mounted. The clamping mechanisms, which may be screw, pneumatic, or hydraulic devices, tightly squeeze the parts being glued together against one another and prevent them from swelling. Static panel-gluing machines have steam or electric heaters to accelerate the hardening of the glue.
In continuous panel-gluing machines, panels are continuously glued together. Workpieces smeared with glue are squeezed tightly against one another, pass through a heating area, and are heated to harden the glue. After the workpieces emerge from the heating area, they are cut into the required sections.
Old manually operated fan-type and conveyor-type assemblers (vaimy) may also be classified as panel-gluing machines. In such machines, clamped panels complete one turn on a horizontal shaft or a conveyor chain; the glue hardens as the panels turn. The panels are then removed, and new workpieces are placed in the empty units.
