のである。In the example shown in FIG. 1, a single synthetic resin sheet 3 is pushed out from a stocker 2 by a pusher 1 and placed on a conveyor 4. The transfer conveyor is equipped with a heating device consisting of an upper high frequency pole 51 that can move up and down and a lower electrode 52 on the lower side of the transfer conveyor. It is held between the open electrodes 52 and heated to a predetermined temperature by applying high frequency waves in this state and softened. After the heating is completed, the transfer conveyor 4 itself is moved forward and moved into the molding device 6 as shown by the - dotted chain line 4. Then, while driving the transfer conveyor 4 to send out the synthetic resin sheet 3, the conveyor 4 itself is moved back and returned to its original position at the same speed as the sending speed, and the softened synthetic resin sheet 3 is It remains in the molding device 6 and is supplied to a predetermined molding position.

As a heating device, an infrared heater 53 is installed above the transfer conveyor 4.
A plate-shaped heater 54 is installed on the lower side, and the transfer conveyor 4 either stops at a predetermined position within the heating device or moves slowly, so that the synthetic resin sheet 3 is heated to a predetermined temperature and softened. After the heating is completed, the transfer conveyor 4 itself is advanced to move it into the molding device 6 as shown by the - dotted chain line 4. Then, while driving the transfer conveyor 4 to send out the synthetic resin sheet 3 as shown by the dashed line 3, the transfer conveyor 4 itself is retreated at the same speed as the sending out speed and returned to its original position. The sheet 1-3 remains in the molding device 6 and is supplied to a predetermined molding position.
