The MiniCoater line of roller coaters places lubricant on coil stock before it enters the die. Computer control allows the MiniCoater to dispense the correct amount of lubricant on each cycle of the press. Individual manifolds can be

A less-obvious cause of carrier-web stretching is roll pressure in the feed sys- tem. In general, the pressure on the feeder rolls should be set as high as possible without causing damage to the material. High roll pressure allows the feeder to accelerate aggressively without the material slipping. However, excessive feed-roll pressure can induce edge wave in the material.
When a die closes on material with edge wave—especially thin materials—the pressure provided by the stripper plate will flatten these waves, causing the car- riers to increase in length during the die operations. When the die opens, the waves return to their original shape and the carrier will become shorter again. This con- dition can create all kinds of in-process variation that can be very difficult to iden-
tify, especially if one is not looking for it.
