PURPOSE:To strip effectively a cover film by pressing and sticking an adhesive film to the cover film given a slit in advance, then withdrawing the adhesive tape to strip the cover film from a printed wiring board and feeding the film securely into a winding conveyor. CONSTITUTION:A printed wiring board 9 is carried with a roller conveyor 6, and the forward end of the board 9 is positioned. Cutters 8 rise and descend so as to pinch the board 9 and to slit cover films 11. The conveyor 6 carries the forward end of the board 9 right under both pressing rolls 14. Tape heads 10 rise and descend toward the board 9 till the rolls 14 reach the faces of the board 9. Adhesive tapes 13 rotate to stick the films 11 and wind them. Stripping of them is facilitated by blowing air into the undersurface of the films 13 (the surface to be stripped). The stripped films 11 are carried into cargoes 20 with the winding conveyors 21. |
