ABSTRACT:
A method of tensioning metallic strips on a slitting line is combined with the steps of uncoiling a metallic web having a non-uniform cross sectional thickness from an uncoiler, slitting the web into a plurality of strips having varying thicknesses, and recoiling the strips into individual strip coils on a recoiler, the tensioning method being the additional step of deforming the thinner portions of the web intermediate the uncoiling and recoiling steps so that a raised pattern is imparted to the thinner portions thereby increasing the effective cross sectional thicknesses of the thinner strips to that of the thicker strips so that the strip coils formed from the strips are of similar diameter and the strips can be recoiled at the same rate, thus preventing the formation of slack strips. The apparatus includes a deforming station having a forming roll with a raised pattern formed on its surface, a pressure roll having a width less than that of the forming roll, and a frame for supporting the forming roll above the pressure roll. The frame includes a movable support for the pressure roll which positions the pressure roll and urges it toward or away from the forming roll.
