Abstract
PURPOSE: To obtain a certain punching operation of the mouldings without any position run-out by installing the guide which guides a sheet between a punching device and by controlling the position of mouldings guiding the projected part of to the lower punching blade.
CONSTITUTION: Thermoplastic resin sheet effecting heat hardening is moulded by a moulding device to form a moulding sheet 31. The sheet is then fed to a mountain shape guide 9 and passes through a pair of auxilairy rollers 10 and 11 to form the passline for the sheet 31 with a slow inclination after a punching device 5. Then, when the lower part of the mouldings passes to the middle point of punching blades 7 and 8, guide rollers 12 and 13 make an intermittent motion to lower and the sheet 31 forms steep inclination passline. After that, upon controlling the position of mouldings, the auxilary rollers 10 and 11 lower so that the mouldings are placed in a punching hole 17a in such a way that the punching blades 7 and 8 punch a moulding P.
