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.
A joining method as a feature of joining single piece successively in which, firstly, on the way to carry a single piece on the conveyor in an orthogonal direction against the joining edge of the single piece, wherein a joining edge of the preceding piece and a joining edge of the succeeding piece come closer, accordingly an adhesive material is intensively supplied to one portion of the edge of the preceding single piece or the edge of the succeeding single piece or to at least one portion within a small limited area on the top or bottom face of each single piece including the joining edges inside, the adhesion enhancing action is supplied to the said adhesive material, therein at least the aforementioned adhesion enhancing action can be supplied at any time while the single piece is being carried or such a motion is halted within a certain length adhesion enhancing section provided on a farther side from the edge approaching position in a carrying direction of the single piece carrying route, and the adhesion enhancing action is applied to the farthest joining edge of the unjoined single pieces which comes first to the aforementioned adhesion enhancing section in a carrying direction,
A joining apparatus comprising a single piece carrying system to establish a carrying route which enables a joining edge of the succeeding piece comes close to a joining edge of the preceding piece, an adhesive material supplying system to supply an appropriate amount of the adhesive material intensively to a portion between the joining edges of the preceding and succeeding single pieces or to at least one portion in a small limited area on the top or bottom face of each single piece including the joining edges inside, together with an adhesion enhancing system comprising an adhesion enhancing component to supply the adhesion enhancing action to the adhesive material, wherein at least the adhesion enhancing system comprising the aforementioned adhesion enhancing component is provided to move back and forth within a certain length adhesion enhancing section provided on the farther side from the edge approaching position in a carrying direction of the aforementioned carrying route, comprising a control system to move the said adhesion enhancing system to the position of the unjoined edge which is the farthest from the edge approaching position in the carrying direction for processing each joining edge which successively comes into the said adhesion enhancing section, and to activate the adhesion enhancing component to supply the adhesion enhancing action to the adhesive material at any time while the single piece is being carried or such a motion is halted.
