When it is desired to put a reverseflange for a door or manhole in the plate being flanged, thisis accomplished by means of the overhead ram, which is ad-justed radially from the center of the press, thus greatly econ-omizing time and avoiding the necessity of reheating the platefor a second operation. In addition to the flanging work, a large amount of otherwork is done on this press, including bending, punching andshaping of material required in the building of internal clamping ram exerts a pressure of 100 tons, andthis pressure may he added to the effective pressure of themain ram, if desired.
