Abstract: The invention relates to a method and an arrangement for jointing wood veneers to each other with an edge joint. In the method, the veneers to be jointed are first positioned with edges to be jointed against each other, and thereafter a jointing operation of the veneers to each other is performed at connection points spaced from each other in the longitudinal direction of a joint between the veneers. The method comprises forming in the to-be-jointed veneers a row of not less than three through-holes at said connection points, said row extending across the joint between the abutting edges of the veneers to be jointed, such that one of the holes substantially coincides with the joint, and thereafter attaching the veneers to each other by means of splicing tools to be fitted in the holes.
Abstract: A method and a system for glulams fabrication, comprising obtaining wood pieces of a target length from raw materials; and assembling them into structural timbers of a target thickness in a continuous line, whereby moisture content, end joints, mixing and applying of adhesives, glue line pressure and clamping time are continuously controlled.

Abstract: An apparatus having several stations that receive, apply adhesive to, crowd, press and cure the wood pieces into a continuous wood panel. A singulation station engages an individual one of the wood pieces oriented in a cross-machine direction from an infeed station, presents the wood piece to an adhesive station for adhesive application and releases the wood piece for crowding at a crowding station into a batch of the wood pieces. A press station downwardly presses the batch with an upper platen and presses the batch in a downstream direction onto the continuous wood panel with a clamping device. A radio frequency device applies radio waves to cure the adhesive between the wood pieces of the batch so as to adhere the wood pieces together and so as to adhere the batch to the continuous wood panel. A cutting station cuts individual wood panels from the continuous wood panel.
