  • Process and device for one- or two-sided stripping of protective films
    Patent number: 5277738
    Abstract: A process and a device are described for one- or two-sided stripping of protective films from board-shaped objects, whereby the protective film is first raised at the leading edge of the circuit board and guided to a takeup reel via a transport mechanism. To assure that the stripping moment of the protective films on the circuit boards is as slight as possible, provision is made that the edge of the protective film is first scratched with extensible hollow needles and raised with a blast of air and that, in the course of the continuing advance of the circuit board, the protective film is lifted onto plate-shaped guide blades and transported away.
