Abstract:
In a laminating system for manufacturing a laminated printed circuit board blank where said circuit board blank has a leading edge and a trailing edge, said laminating system being of the type that includesan inlet zone and a discharge zone spaced from each other along a path along which the printed circuit board blank travels as it being laminated, said inlet zone including means for receiving a thin sheet of metal into which the circuit is to be printed and a layer of light sensitive material, a plurality of sets of heated rollers, the rollers in each set being heated and being in selective pressing engagement with each other to press the layer of light sensitive material into close engagement with the thin sheet of metal so that said layer of light sensitive material is bonded to said thin sheet of metal to form a lamination, and said discharge zone is for receiving said laminated circuit board blank,the improvement comprising;a frame disposed along said path of travel and adjacent to said discharge zone of said laminating device for receiving said laminated printed circuit board blank after it is received in said discharge zone,said frame supporting a plurality of sets of heated rollers, said sets of rollers being disposed longitudinally along the path of travel of said laminated printed circuit board blank,each of said sets of rollers including two rollers, the axes of said rollers in each of said sets being in vertical alignment with respect to each other so that the path of travel through each set of rollers is in the horizontal plane,means interconnected between the rollers on one side of the horizontal plane for driving said rollers on said one side of the horizontal plane in the direction of the path of travel of the laminated printed circuit board blank,means for heating the rollers in each of said sets of rollers, andmeans for selectively moving the roller in each of said sets on the other side of the horizontal plane vertically toward and way from the roller on said one side of the horizontal plane as said laminated circuit board blank moves through said sets of rollers along said path of travel.
