FOUR COLUMN POSITIONING MECHANISM FOR CALENDER MACHINES Abstract of the Disclosure A positioning mechanism for four column calender machines is disclosed. The mechanism employs an interconnected piston and cylinder arrangement to permit the rolls to be quickly separated and subsequently automatically re- positioned. The rolls are supported on a plate assembly movable on a vertically disposed way mounted on the columns. A lost motion arrangement is pro- vided in the plate assembly so that when a paper break occurs or when it is otherwise desired to separate the rolls quickly, the cylinders are released permitting rapid relative movement between the rolls to prevent damage.
