ABSTRACT:
A cold sheet metal forming apparatus in which the forming rolls are held at each end by bearing housings in each case held by screw-threaded rods engaging the housings and being secured directly to a main supporting frame.
Such an arrangement leaves additional room between adjacent pairs of rolls and a second set of rollers are nested between the first set also with the simplified support arrangement at each end of each roll so as to allow a second rolling line to be kept in position and available for prompt use without as has hitherto been the case the necessity to change rollers.
