ABSTRACT:
An apparatus and a method for making a continuous solid wood-laminated panel from elongated wooden blocks precoated with glue along two right angular edges. An elongated table is provided at its feeding end with a plurality of rack members disposed over the same for holding individual stacks of glue-coated wooden blocks at a feeding station with the blocks all aligned longitudinally of the table and equally offset transversely of the table. A power-actuated ram member is slidable along said table and has a stepped ram edge engageable with the lowermost blocks of each stack and movable transversely and forwardly of the table to push the blocks against the longitudinal and transverse edges of a previously-arranged group of such blocks pressed on the table by a pressing plate, the blocks being pressed between the ram member and an abutment shoulder arranged longitudinally of the table on the opposite side from the ram member, the ram member then accomplishing a longitudinal forward stroke to push the blocks under said plate forwardly longitudinally of the table, reciprocating movement of the ram member causing successive groups of wooden blocks to be assembled and joined together. The apparatus further includes an electrode plate fed with a high-frequency electrical supply means to cure the glue at the joints between successive groups of blocks while pressing the same against the table. The apparatus finally includes a braking plate at the forward end of the table, which retards the forward movement of the panel.
