MANUFACTURING DEVICE FOR LITHIUM THIN FILM PIECE

PURPOSE:To enable mass production of an Li thin film piece having a fixed thickness by holding together the endless belt of a rotary belt mechanism and a band Li thin film while using an endless belt having plural punched holes in the longitudinal direction. CONSTITUTION:Firstly, a band Li thin film is pulled out from the Li hoop 42 of a feeder mechanism 38 for being moved along the upper part of the endless belt 7 of a rotary belt mechanism 8 and one end of the thin film is wound about the coiling bobbin 53 of a coiling mechanism 51. Next, a punch 37 on the underside of a base stand 33 is made to go down. At this time, plural punched holes are opened in the belt 7 in its longitudinal direction so that punching of the Li thin film is performed. Next, while the belt 7 makes turning motion smoothly, the band Li thin film is moves by the length corresponding to travel stroke of a stand plate 10. At this time, the mechanism 38 is suspended by a lifting mechanism 43 with a load 49 balancing with its weight so that the tension to be applied to the thin film part near the mechanism 38 at the time of carrying the band Li thin film can be suppressed.
