LAMINATOR

PROBLEM TO BE SOLVED: To supply film to a base automatically and continuously by arranging a pair of shafts to which a paper tube with a film stock wound around and a paper tube for taking up a cover film are fitted, on a rotary disc in a freely rotatable manner and thereby switching the supply of the film continuously. SOLUTION: Paper tubes 10, 20 around which film stocks 11, 21 are wound and paper tubes 14, 24 for taking up cover films 13, 23 are fitted to drive shafts 15, 25 for supply and drive shafts 16, 26 for take-up respectively. These paired shafts are arranged on a freely rotatable rotary disc 5. A film 12 obtained by peeling the cover film 13 from the film stock 11 is deposited on a base 1. In this case, when the film 12 is almost exhausted, the rotary disc 5 is rotated clockwise to thermally deposit a following film 22 on the preceding film 12 and the film 12 is cut slightly upstream from the thermally deposited spot of the film. After that, the rotary disc 5 is rotated as far as it reaches an opposite position to its home position and a new film stock is mounted on the rotary disc 5.
