Abstract: An apparatus and method for removing crushing rolls from a crushing apparatus is disclosed in which arms means mounted on a movable frame supporting movable crushing rolls which move with the movable frame are utilized to remove stationary crushing rolls mounted on a stationary supporting frame to a position at which the stationary rolls may be lifted from the crushing apparatus. With the stationary and movable frames adjacent to each other, the arm means are placed in supporting engagement with the stationary crushing rolls mounted on the stationary frame. The crushing rolls mounted on the stationary frame are then released from its support so that the stationary crushing rolls are supported by the arm means. The movable frame is then moved away from the stationary frame to move the stationary crushing rolls supported by the arm means to a position at which the stationary crushing rolls may be lifted from the arm means.

Abstract: A die for repetitively cutting shapes out of material such as paper and cloth includes a continuous, seamless metal wall defining a central opening having a predetermined shape substantially the same as a shape it is desired to cut. A cutting surface is disposed at the top of the metal wall, the cutting surface defining the outline of the shape it is desired to cut. Such dies are formed by cutting a die blank out of a block of metal, the outline of the die blank corresponding generally to the shape it is desired to cut. At least part of the interior of the die blank is removed to form a modified die blank with a central opening having substantially the same shape as the shape it is desired to cut. A cutting edge is formed on one surface of the modified die blank adjacent the central opening by electric discharge machining.
