The suction port 72 being connected in vacuum pump 71 is located at above the side of containing case 71, and because being provided with large through hole 77 in the top of division board 76, above the containing case 71 in the source of self-conductance approach 74, air comparatively strongly attracts.Its result, imports road 74 by the residual part film F r of removing with in great power inspiration containing case 71.On the other hand, because the through hole 77 be located at below division board 76 is little, self-gravitation mouth 72 becomes stable in the attraction of distant place containing case 71 lower air, and the residual part be sucked in containing case 71 drops down onto the below (Fig. 4) of containing case 71 from body weight by it.
Even if how many residual part film F r falling to the below of containing case 71 is floated by the attraction of self-gravitation mouth 71, because having division board 76 at the end of containing case 71 and suction port 72, residual part film F r is sucked into suction port 72 and does not stop attracting.
Control part 80, only makes lower roll 61b rotate both after fixing turn, motor 64 is stopped.Thus, residual part film F r overall by carrying roller to 61, and collecting is in the containing case attracting resettlement section 70.In addition, vacuum pump 73 stops, and makes top roll 61a rise (step S18) by roller elevating mechanism 65.As done above, waste wood and residual part film F r are from excision base station 51 removal.
Thereafter, get back to step S11, step S11 repeatedly ~ S18.As done above, circular release film sheet material is by continuously and make unchangeably.
So, if by the thin-film sheet device for excising 30 of the present embodiment, to often make residual part film F r (waste wood) that a slice release film sheet material produces from long band release film F severing and from excision base station 51 removal, because long band release film F is reconfigured by fixture 42, the distortion that the situation as batched in the past at this point that can not produce produces or gauffer.In addition, in the recovery of residual part film F r, the laminar flow also by utilizing the attraction of air to be formed, can prevent electrostatic from causing the problems such as the attachment of residual part film F r guide approach 74.
