Abstract
An apparatus for plastically deforming a work piece. The apparatus comprises at least two cylindrical guide rolls rotatable in a first direction, a bendable strip having a portion of at least one surface in communication with a portion of an outer circumference of each of the at least two cylindrical guide rolls, a first cylindrical feeding roll rotatable in a second direction opposite to the first direction, and a plastic deformation passage having a first surface and a second surface, at least a portion of the first surface being defined by a portion of the bendable strip, and at least a portion of the second surface being defined by the outer circumference of the first cylindrical feeding roll. One or both of the bendable strip and the cylindrical feeding roll, when in motion, propel the work piece through the plastic deformation passage wherein the work piece is plastically deformed.
