ABSTRACT:
This invention provides joining methods of single veneer piece and a joining apparatus, which can produce more efficient, and effective joining process than the conventional method and apparatus produce. In the process of carrying a single veneer piece (T) in the orthogonal direction against the joining edge (Te) on the conveyor, the joining edges of the preceding and succeeding single veneer pieces come close together, the adhesive material (Sd) is supplied to the clearance between the joining edges, and then the adhesion enhancing action is supplied to the said adhesive material (Sd) to join each single veneer piece (T) successively. The adhesion enhancing action can be applied within the adhesion enhancing section as indicated by lines (Z1) and (Z2), provided on the farther side from the edge approaching position (U) via an adhesion enhancing component (6) to move back and forth at any time while the single veneer piece (T) is being carried or such a motion is halted. And such adhesive enhancing action is applied first to the adhesive material (Sd) which has been supplied for adhering the joining edge positioned on the farthest side in a carrying direction all the time.
