摘要： PURPOSE: To manufacture an elegant decorative plywood which is free from a fissure(split atmosphere) in the corner when a decorative sheet is folded. CONSTITUTION: A decorative sheet 12 with a printed vein pattern or a printed abstract pattern is adhered to one side of a flat board base 11, and on the other hand, a foldable groove which is deep enough to leave the decorative sheet 12 alone is notched on the remaining one side of the flat board base 11. In addition, the flat board base 11 is fixed by folding the foldable groove in a closable angular state, while the decorative sheet 12 is caused to come to an outer angle side. In this decorative plywood manufacturing method, a precoated paper is used as the decorative sheet 12, and a vinyl acetate resin emulsion adhesive with an elongation percentage of about 390% or higher at a measurement temperature of 20 deg.C is used as an adhesive for the flat board base. The precoated paper is bonded to the flat board base 11 before the adhesive 13 could be dry so that both become integrated into a single piece.

摘要： PROBLEM TO BE SOLVED: To automatically and correctly cut a decorative sheet in a green- bonded state, which is connectively laminated on a plurality of base boards, at portions of joints of the base boards. SOLUTION: A plurality of base boards M connected to one another with the aid of a decorative sheet S in a green-bonded state, which is laminated on the surfaces of the base boards M, are transferred in one direction. In cutting the decorative sheet S at portions of joints of the base boards M, a cutter 28 is confronted to one of the adjacent base boards M from above in a crosscut condition and, under this condition, the other remaining base board M is elevated, whereby the above-mentioned decorative sheet S is pressed against the cutter 28 to be cut.

摘要： PURPOSE:To obtain a defending efficiency against timber injurious insects and sanitary injurious insects by providing a great number of receiving holes for injurious insect defending agent distributed over the entire area of not only the superficial board but also either the superficial board and core board and adhering integrally the film layer of the injurious insect defending agent to the superficial board. CONSTITUTION:The superficial board 11 and reverse board 12 are adhered to the core board 10 via the film layers 15, 14 of the injurious insect defending agent and integrated each other. A great number of receiving holes for injurious insect defending agent (S) are processingly provided on the entire area of the superficial board 11. Because the film layer 18 of the injurious insect defending agent is adhered and integrated, the injurious insect defending agent is saturated into the receiving holes (S) in a large quantity, so that, regardless of the thickness fluctuation of the core board 10, the constantly stable and years continuing insect proof efficiency can be obtained and the duration as an insect proof plywood can also be improved. Furthermore, if the receiving holes (S) are communicatingly opened to not only the superficial board 11, but also the core board 10, then the saturating quantity of the injurious insect defending agent is further increased, as a result, it becomes further profitable because the volatility thereof can efficiently be restrained.

摘要： PURPOSE:To reduce the size of an apparatus and improve operational efficiency, by providing a device for joining together one sheet of plywood at each side of a center plate and a device for attaching an adhesive tape to the joint portions of the two sheets of plywood while moving thereon. CONSTITUTION:Upon the insertion of a first sheet of plywood P into a conveyor 51 through a supporting stand 50, a hold-down roll 53 is moved downwards and conveyors 51 and 55 start to move in the unloading direction and, upon passing of the rear end of the plywood P through a photosensor PH2, a hold- down plate 54 is moved downwards, the hold-down roll 53 is moved upwards and the conveyors 51 and 55 reverse movement to carry the plywood P in the reverse direction. Upon the insertion of the subsequent second sheet of plywood P on the conveyor, a friction roll device 36 is moved upwards and a roll 38 and a block 39 are moved downwards and, with the plywood held therebetween, a head part 4 starts to move. As the head part moves, a center plate 49 is moved downwards sequentially and the edge of one sheet of plywood P at each side of the head part 4 are abutted together by the joining action of rolls 38 and 41 and an adhesive tape T is attached to the joint edges thereof by a hold-down roll 15.
