PURPOSE: Provided is a laminator, and more particularly, an improvement in the structure of a film holding member which is provided near a laminate roll to laminate a film on a plate. CONSTITUTION: A laminator which employs the auto-cutting method includes, as its main components, a pair of laminate rolls (pressure rolls) 2, 2, a film holding member 5, tacking members 1, 1, a film cutter 3 (shown in Figs. 14 and 15), and a cutter backup 4. There is also a film 6 provided upward in the form of a film roll. Here, film 6 means a dry photo-resist film (DRF). The dry photo-resist film (DRF) has the three-layer structure of a base film, a photo-resist film, and a cover film when it is wound around the film roll. In laminating the dry photo-resist film on a plate 7 described below, only the cover film is removed and the photo-resist film plane is applied to plate 7. Tacking members 1, 1, cutter backup 4, and film holding member 5 are connected to a negative pressure supplying apparatus. Film sucking bores 10 which can be supplied with negative pressure are provided in such contact surfaces of tacking members 1, 1, cutter backup 4, and film holding member 5 that are in contact with film 6. By properly applying negative pressure to film sucking bores 10 using the negative pressure supplying apparatus, film 6 is sucked and held as necessary. Film cutter 3 has a rotary circular blade, and cuts film 6 by moving in the width direction of cutter backup 4 while rotating the rotary circular blade. |
