PURPOSE:To improve the working environment of adhesive application and reduce the cost by forming a plywood adhering sheet placed between veneers from a material wherein a low density polyethylene is incorporated with a modified polyolefin having a polar group. CONSTITUTION:A sheet 12 is constituted of a material wherein 100 pts.wt. low density polyethylene are incorporated with 7 pts.wt. or more modified polyolefin having a polar group. A belt-like veneer belt 21 with a thickness of a 2mm is formed from a raw wood (w) by wig peeling using a cutter 20 and on the way of the veneer belt 21 to a winding roll 22, the sheet 12 is attached to the whole surface. A product wherein the sheet 12 is placed between layers of the veneer belt 21 is prepd. thereby, on the winding roll 22, split of wooden fiber is prevented by adhesiveness of the sheet 12. In addition, as placing the sheet between the veneer belts is easy, the productivity of plywood is remarkably improve while the working environment being improved without flying of an adhesive. |
