Abstract
Apparatus comprising a feed carriage which can traverse back and forth in the running direction A of a base. Two cutting units are arranged on the feed carriage, which units consist of lifting cylinders to which vacuum bars and holding beams with cutting bands are fixed respectively. Photoresist webs to be laminated onto the base are advanced by a pair of transport rollers by way of deflection rollers and drawn to the vacuum bars which are lowered and raised, respectively, in the direction of the base in order to press the photoresist webs onto the two sides of the base. An optical sensor detects the front and rear edges of each base and controls the moving together and apart of the vacuum bars, the application of negative pressure to the vacuum bars, as well as the neutralizing of the negative pressure, and the cutting movement of the cutting bands.
