The product of pressure multiplied by time is a useful parameter to describe the combined effect of these two factors. This product is called "press impulse". The press impulse can be determined from the quotient of two readily known variables in pressing, the line loading (N/m) divided by speed (m/s).

Due to its high rotational speed and heavy load, the die has to be securely harnessed to the shaft. This is achieved by means of a two-piece die cover assembly (10) and 12 strong bolts (11). The rollers usually have a hardened shell with indentations on the surface to provide traction and to reduce slippage of feed.
