PURPOSE:To prevent the generation of wrinkles or scratch on a finished surface, by mounting a lift means for pushing down a press plate to the pressure receiving surface formed by the roller supported by a guide member. CONSTITUTION:The box passing the fourth sensor S4 is placed on the successively molding rollers of a feed and pressure-receiving apparatus 30 and, when the box advances to the pressing position of a press plate 40 standing by at the rising position of a press part, said box is stopped by the second stopper 62 and the fifth sensor S5 is turned ON. The air cylinder 52 of a lift means starts to fall on the basis of the sensor and, at the same time, a timer is started and the press plate 40 falls within the predetermined time up to time-out by the cylinder 52 to be inserted in the stopped box and presses the bottom part of said box but the under surface of the bottom part of the box is in contact with the upper surfaces of the successively moving rollers 34 and each of the rollers 34 is coated with an elastic material having flexibility and a low friction coefficient such as urethane rubber. |
