Film transfer apparatus

摘要

A film storage unit is disposed vertically above a film transfer cylinder, and an unwinder device and a rewinder device are disposed vertically above the film storage unit. The unwinder device and rewinder device are vertically aligned with each other. With this arrangement, a large-diameter unwinding reel and a rewinding reel can be mounted in the unwinder device and rewinder device, respectively, from above a foil transfer unit. Also, given operation spaces can be ensured on the front and rear sides of the unwinder device and rewinder device.

主权项

1. A film transfer apparatus comprising:
an unwinder device which rotatably supports an unwinding reel including a film wound therearound, and unwinds the film from the unwinding reel; a film storage unit which forms a U-shaped portion in the film supplied from said unwinder device and stores the film; a film transfer cylinder which is supported rotatably and presses the film delivered from said film storage unit against one of a sheet and a web; and a rewinder device which rotatably supports a rewinding reel, and rewinds around the rewinding reel the film transferred via said film transfer cylinder, wherein said film storage unit includes an air blow device which blows air toward a bottom portion of the U-shaped portion of the film an infeed roller which pulls the film stored in said film storage unit out of said film storage unit to transfer the film onto said film transfer cylinder, a suction film feed device disposed on a side on which the film is supplied from said unwinder device, and a suction film delivery device disposed on a side on which the film is delivered by said infeed roller, wherein said suction film feed device includes a feed-side suction unit which includes a feed-side guide surface opposed to one side surface of the U-shaped portion of the film, and draws the one side surface by suction, and a conveyor belt which is disposed between said feed-side suction unit and the one side surface of the U-shaped portion of the film, and transports a one-side surface portion of the U-shaped portion of the film, and wherein said suction film delivery device includes a delivery-side suction unit which includes a delivery-side guide surface opposed to the other side surface of the U-shaped portion of the film, and draws said other side surface by suction, wherein an other side surface portion of the U-shaped portion of the film is pulled out of said film storage unit by only said infeed roller.
