Apparatus for laminating sheets with a plastic film

Image Number 4 for United States Patent #4505772.

In an apparatus for laminating sheets of paper, card or board with plastic film which, for example, is clear and transparent, an intermittently running sheet feeder (2) is disposed upstream of a continuously running laminating device (4) and an intermittently running cross cutter (43) is disposed downstream of the laminating device. The sheet feeder (2) and cross cutter (43) have conveying drives, which can be switched on and off, and photoelectric barriers (27, 28, 50) which traverse the conveying track and, via timing elements and control devices, control the conveying drives in the sheet feeder and in the cross cutter in accordance with the mode of operation of the laminating device.
