CONTINUOUS MANUFACTURE OF LAMINATE

摘要

PURPOSE:To constitute the subject method so that an abnormal outflow of impregnating resin is not generated and only resin existing between base materials is discharged even if pressurization is performed, by a method wherein the title laminate is impregnated with side chain double bond type resin, a fine diameter rolling roll is applied to an endless belt, which is placed between the belt and a stationary pressure plate and a free rotation of a rolling roll is used. CONSTITUTION:A laminated body comes out of a squeeze rollers 7 is introduced between endless belts 9, 10 made of steel. Belts each are stretched at fixed tension with belt tension adding rollers 10, 10 and a space between a pressure plate 11 for pressurization and the belts each becomes uniform or that on an upstream side is a little wider. Since a roll group of a small diameter corresponding to the minimum space is between the pressure plate 11 and belts each and mounted on a crawler surrounding the pressure plate 11 for the pressurization the roll rolls along with a movement of a laminate and the endless belts 9, 10 through its friction force and turns on the crawler. When a belt side surface of the pressure plate 11 for the pressurization is kept bent slightly, gentle discharge of the impregnating solution is continued at an upstream side, the pressure is kept on at a downstream side and formation of the laminate becomes easy. Since the impregnating solution between the base materials is discharged mainly in the side chain double bond type resin, the same is suitable for the title method.
