Method and plant for producing endless laminated veneer boards

A method for assembling, gluing and pressing veneer panels into a plurality of layers, one panel behind another panel, forming a continuous strand of laminated veneer panels, comprising the steps of:

• (a) conveying, at a speed equal to an operating and pressing speed, a veneer panel through a glue application machine and providing an uppermost surface of the veneer panel with a layer of glue;
• (b) transferring the veneer panel from the glue application machine to a buffer acceleration belt including a transfer projection;
• (c) transferring the veneer panel from the transfer projection to a supporting surface of a laying device, the supporting surface moving via a re-circulating chain device and circulating via two rollers into a predetermined deposition, while the veneer panel is guided on an upper level of the laying device by a front edge;
• (d) stopping the veneer panel at the front edge by contacting a first stop, while the supporting surface continues to circulate underneath the veneer panel by the re-circulating chain, the re-circulating chain including the supporting surface and a fall-through gap;
• (e) releasing a rear edge of the veneer panel causing the rear edge to fall through the fall-through gap into a second stop on a lower level of the re-circulating chain device onto the supporting surface, while the supporting surface moves underneath the veneer panel in a counter direction;
• (f) releasing the veneer panel from a second stop by continuous circulation of the supporting surface causing the front edge of the veneer panel to fall onto a veneer-assembly laying belt, while the veneer-assembly laying belt moves at the operating speed to the predetermined deposition position;
• (g) repeating steps (a) through (f) for a plurality of veneer panels to assemble the veneer panels with an overlap thus forming a veneer assembly and assembling each of the veneer assemblies, one veneer assembly behind another veneer assembly forming a veneer panel strand;
• and
• (h) transferring the veneer panel strand, at the operating speed, from the veneer-assembly laying belt into a heated continuously operating press for pressing and gluing the veneer panel strand.
