Abstract
PURPOSE:To manufacture a continuous molded product of almost uniform thickness in its whole length by press molding a short length synthetic resin sheet while preventing the molten resin from flowing out at a rear end pinch-off section of a press mold, and simultaneously welding the front end of the short length synthetic resin sheet with the rear section of said molded product to connect together integrally. CONSTITUTION:When press molding is completed, a top force main body 11a and a press molding die 11b are lifted up, and a solidified molded product is released in a manner that its rear end is left in a press mold 1. Then, the rear end of said molded product X is press fixed with the press molding die 11b which is lowered after release. In said state, a following heated short length synthetic resin sheet X2 is set in the press mold 1, and the top force main body 11a is lowered to carry out press molding again. By said arrangement, the front end of the short length synthetic resin sheet X2 is welded with the rear end of the foregoing molded product X in a state of butting to be connected together integrally, and is molded in the thickness similar to that of the foregoing molded product A, because the molten resin is prevented from flowing out at a rear end pinch-off section 13 of the press mold 1.
