BFN 7033 METHOD AND APPARATUS FOR TENSIONING METALLIC STRIPS ON A SLITTING LINE ABSTRACT OF THE DISCLOSURE A method of tensioning metallic strips on a slitting line is combined with the steps of un- coiling a metallic web having a non-uniform cross sectional thickness from an uncoiler, slitting the web into a plurality of strips having varying thick- nesses, and recoiling the strips into individual strip coils on a recoiler, the tensioning method being the additional step of depositing a strippable polymeric compound onto thinner strips so that the effective cross sectional thicknesses of the thinner strips is increased to that of the thicker strips so that the strip coils formed from the strips are of similar diameter and recoil the strips at the same rate, thereby preventing the formation of slack strips. The apparatus includes a hot melt unit for generating strippable plastic in liquid form, a hot melt gun communicating with the apparatus, a support frame and movable arm on which the gun is mounted, and a motor driving a rack and pinion for posi- tioning the hot melt gun over a selected strip coil.
