Abstract

Described is a cut-sheet lamination using a laminator for the single or double-sided application of a film cut onto a printed circuit board using heated overlay rollers located opposite to each other in a housing. The printed circuit board and the cut film are fed to the overlay rollers simultaneously in the overlay region. The printed circuit board is led in with input rollers, and the film is pulled off a supply reel and is guided over input rollers to the printed circuit board. A cutting fixture is provided within the region of the input rollers. The cutting fixture cuts the film corresponding to the length of the printed circuit board in accordance with a sensor scan. The cutting fixture is put onto a lever capable of swivel motion. The cutting fixture travels along with the film at the cutting of the film, and the lead-in rollers for the film in the region where the cutting occurs are constructed as suction rollers. This provides continuous through movement of the printed circuit boards through the overlay rollers which reliably avoids damage to the photo-materials there.
