ABSTRACT:
The invention provides a simply-constructed apparatus for applying a substantially fixed amount of adhesive onto a scarf-cut face of a veneer. The apparatus includes: a plurality of rolls (2,4,48,50) for successively feeding veneers in a predetermined feeding direction along fibers of the veneers; a plurality of detectors (6) for detecting existence of a veneer; an adhesive reservoir (40) having a length, in a direction perpendicular to the feeding direction, equal to or greater than the width of the veneers; an adhesive application member (24) having a length, in the direction perpendicular to the feeding direction, equal to or greater than the width of the veneers; and a plurality of pivot mechanisms (26) and lifting members (28) for reciprocating the adhesive application member (24) between a first position and a second position. At the first position, the adhesive application member (24) is inserted into the adhesive reservoir (40) to take a substantially fixed amount of adhesive on adhesive-applying faces (24a, 24b) of the adhesive application member (24). At the second position, the adhesive-applying faces (24a, 24b) of the adhesive application member (24) is pressed in a substantially parallel configuration against a scarf-cut face of the veneer to apply the substantially fixed amount of adhesive on the adhesive-applying faces (24a, 24b) to the scarf-cut face of the veneer.
