To speed up triming operation by constituting a trimming device with a crank mechanism, and to enhance the productivity by operating the crank mechanism in synchronization with a tact time with which a molding machine on a molding line is operated so as to carry out on-line operation with the molding machine.
An outer peripheral trimming device 16 is composed of a trimming part 16a, a trimming drive part 16b and a motor part 16c, and a crank mechanism 16b1 is used in the trimming drive part 16b so as to speed up trimming operation of in the outer peripheral trimming device 16. Accordingly, the outer peripheral trimming device 16 can be incorporated in a thermally molding line so as to carry out on-line operation with a molding device, thereby it is possible to enhance the productivity of the thermally molding line.
