Abstract
Abstract The self-centering edge conditioning unit for a moving sheet metal strip is an element placed in a strip conditioning line to assist in removing non-uniform terminal residual stresses which may be produced therein and which may actually result in physical deformation of the strip, such lateral curvature sometimes being known as ''''chamber.'''' The edge conditioning unit comprises a pair of assemblies pivotally mounted on two composite arms which have a common pivotal connection to a base frame. The arms are provided with lateral extensions, one of which is connected to a bracket for mounting an air cylinder and the other of which is connected to a piston rod projecting from the air cylinder. When energized, the air cylinder moves the arms in such fashion that the self-centering edge conditioning assemblies engage the opposite edges of a moving sheet metal strip. Each assembly comprises spaced bottom and top plates with the spacer at the center of each assembly serving as the pivot point for connecting that assembly to one of the pairs of arms. Each assembly also includes a pair of spaced-apart floating edge rolls having a central peripheral notch or recess in which the edge of the strip is engaged. Each edge engaging roll rotates against a pair of backup rolls which are pivotally mounted upon and between the top and bottom plates. The edge engaging rolls do not have a fixed center of rotation and are prevented from falling free of the assembly by a pair of pins which may be engaged by the periphery of the strip edge engaging roll when no strip is placed or passing between the assemblies.
