| 摘要 | PURPOSE:To simply perform arbitrary bending, by applying a simple cutting process for bending decorated plywood which is formed by laying a synthetic resin decorated sheet or a synthetic resin decorated film on the surface of a base board. CONSTITUTION:In the bending portion 9 of a laminate 1, a plurality of deep parallel slots 10, 10,... each having a slender rectangular section are cut in a plywood 2 opposite to a decorated sheet 3 at an interval virtually equal to the width of the slots, on the back side, along a bending line and in the width in which the curved surface of the sheet 3 is formed, while a face veneer 4 is left uncut. Accordingly, these deep slots 10, 10,... and intervening partitions 11, 11,... each having a section virtually in the same shape with that of the slots are provided alternately in parallel. The bending surface is finished to be smooth by simply bending the laminate lightly by hands when the decorative sheet 3 is made of thermoplastic resin material, and by bending it with heat applied from outside as occasion calls when said sheet is of thermosetting resin material. The group of intervening partitions 11 serves to reinforce the bending portion 9 from inside. | ||||||
