Multiblanking lines are used to produce small, accurately shaped blanks directly from large coils. Modern lines can process many different types of material over a range of thicknesses, while still allowing quick changeovers and minimal maintenance. New technology is available in several key areas that limit the capacity of a typical multiblanking line, which include leveling, slitting, feeding, shearing, and stacking.

Gripper or roll-type feeds operate on the principle of feeding force, which is a product of the coefficient of friction between the grippers or feed rolls and the material being fed. Reviewing each force as a factor of the feeding equipment or feeding conditions helps in evaluating the feeding process.
