Abstract: An apparatus for regulating a leading end stacked position in a stacker for successively stacking thin sheet materials.

Abstract: A heating plate is disclosed which is adapted for use in a dryer for drying a sheet of wood veneer by heating said plate at a desired level and placing one surface of the plate on either side thereof in engagement with the veneer sheet. The heating plate, when heated and placed in non-engagement state, is formed such that said one surface is convex shaped.

Abstract: Method of correcting the track of an intermittently-running endless belt in a veneer dryer is disclosed. In a veneer dryer having a pair of intermittently movable endless belts provided under tension so as to form at least one straight passage therebetween through which a veneer sheet is conveyed by the endless belts while being heated by heating plates located above and below the passage, and means disposed adjacent to the opposite lateral edges of the endless belts and movable toward and away from said lateral edges for moving the belts laterally, the tension is released to loosen the belts after a predetermined number of stops of the endless belts and the belts are then moved at the edge thereof on the side corresponding to the direction in which they are displaced, by said means located adjacent to said edge, until an area of normal running track is reached by the belts.

Abstract: A method and apparatus for bonding veneer sheets is disclosed. It comprises stacking up a plurality of veneer sheets with water soluble thermosetting adhesive interposed at desired locations between the veneer sheets; pressing the veneer sheets from both above and below surfaces thereof; sealing the gap defined by the two opposing plates in the vicinity of the peripheral portions of the veneer sheets in an air-tight manner; heating the bonding agent at a temperature of a boiling point or more of water in its normal state; and hardening the adhesive while preventing the same from foaming.

Abstract: A plywood is manufactured by applying an aqueous plywood adhesive fluid to the peripheral surface of a heating roll rotating at a given speed by means of a roll coater to form an adhesive fluid film, drying the adhesive fluid film into a tacky-dry film while it is carried on the surface of the heating roll, stripping the tacky-dry adhesive film from the roll surface by pulling it under tension with or without the aid of a stripping knife, interposing the adhesive film between a pair of veneers, and pressing the veneers to each other to bond them.
