ADHESIVE SHEET FOR WOODY PLATE, ITS PRODUCTION AND BONDING OF FANCY VENEER

摘要

PURPOSE:To make it possible to prevent a fancy veneer and a base plate from warping, twisting or the like by integrally heat-bonding a specified heat-meltable resin sheet and a fiber aggregate sheet. CONSTITUTION:A heat-meltable resin sheet 3 of a thickness of 10-150mum, obtained by extruding a mixture of 95-50wt.% ethylene copolymer of a comonomer content of 5-50wt.% (e.g. ethylene/vinyl acetate copolymer) with 5-50wt.% tackifying resin (e.g. rosin) from a nozzle 4c of an extruder 4B, is fed between a pair of press rollers 5 and 6 to bond it to either surface of a fiber aggregate sheet 2, and pulled out of a guide roller 7 to obtain an adhesive sheet 1 for woody plate. A fancy veneer 9 is placed flat on said sheet 1 placed flat on a release paper 8, and the assemblage is heated under a pressure through a heat presser to bond integrally the fancy veneer 9 to the sheet 1 and the release paper 8.
