ABSTRACT:
Tread plates on mutually opposed endless belts clamp and move a pack of boards horizontally lengthwise between electrodes for setting adhesive between the boards by dielectric heating. The tread plates are engaged by backing members spaced transversely of the length of the belt, and the tread plates are connected by a chain located between the backing members. The portions of the tread plates engageable with a surface of the board pack are of a suitable plastic to deter passage of radio-frequency energy from an electrode to an electrically-grounded portion of a tread plate or to the chain. Air bags are inflatable to press at least one endless belt against the board pack or to move such belt relative to supporting means away from the board pack. Adjusting means for prepressing rollers ahead of the endless tread belts on one side of the board pack and adjusting means for the endless tread belt on the same side of the board pack are interconnected for synchronized adjustment. A plurality of pivoted pressure rollers spaced lengthwise of the path of movement of the board pack ahead of the endless belts for engaging the board edges are connected by chains to synchronize them for conjoint movement toward and away from the sides of the board pack. Such rollers can be profiled to hold the boards of the pack in relatively offset relationship if desired. Also, the endless belts can be curved to bend the pack of boards lengthwise.
