ABSTRACT:
A method and apparatus for cutting predetermined lengths of panels from a continuous strip of flexible material and for forming the lengths of panel members to have a preselected panel profile. The strip is reel fed to a first strip driving station which drives the strip through a shearing station, over a hump table, to a second strip driving station and through a strip forming station. In sequence, the second strip driving station brakes the leading portion of the strip to effect a strip hump over the hump table, which is detected by a protoelectric sensor for hump height and signals the first strip driving station to vary its feed rate to maintain the hump; the second driving station is then signaled to commence driving the lead portion of the strip to the strip forming station. When a predetermined panel length is detected by the first strip driving station, it slows and stops the strip and signals the shearing station to cut the strip, whereupon, during this strip feed pause, the hump dissipates as it continues to feed the terminal portion of the panel length to the strip forming station.
