Abstract

An apparatus for use in forming core layers for plywood from a plurality of veneer sections includes a manifold which extends transversely to a work flow path and across which the veneer sections are sequentially moved.
An adhesive passage in the manifold is connected in fluid communication with a plurality of modular dispenser guns.
Each of the modular dispenser guns is connected in fluid communication with either an adhesive dispenser head or a string dispenser head. At the adhesive dispenser heads, adhesive is engaged by the leading end portion of a veneer section and pressed against the trailing end portion of a next preceding veneer section. At the string dispenser heads, string coated with adhesive is applied to downwardly facing major side surfaces of the veneer sections. Each of the modular dispenser guns includes a valve which is operable between open and closed conditions and an actuator which effects operation of the valve between the open and closed conditions.
