The Blanket Cloth Washer Assembly is installed on to the press and its mated to a small pneumatic cylinder with a pointed rod in the middle, when Blanket Cloth Washer Assembly is installed the pointed rod of the pneumatic cylinder is depressed that is when the air leaks but it does not leak when pointed rod of of the pneumatic cylinder is not depressed ( Blanket Cloth Washer Assembly not installed ).
