ROLLER CENTERING APPARATUS

摘要

An apparatus for centering a strip of elastomeric material within a processing apparatus comprising noncontact edge sensing means for sensing at least one edge of the strip of elastomeric material as it is moving through the apparatus and at least two rotatable guide wheels pivotally mounted in a spaced relationship beneath the strip of elastomeric material and having pointed projections about the periphery for penetrating a bottom surface of the strip and for supporting the strip, the wheels being relatively narrow with respect to the transverse width of the strip. Steering means are adapted to pivot the wheels about axes orthogonal to the surface of the elastomeric material in response to electrical signals received from the edge sensing means for centering the material.
