Claim 3
Dependent Claim
132 words
Apparatus for shaping the edges of advancing metal strip comprising: a. a carriage mounted for straight line movement toward and away from a side of said strip, b. a pair of opposed rolls mounted one above the other on said carriage and adapted to be driven to counter-rotate in a direction from a side toward the center of said strip on axes which are parallel to the longitudinal axis of said strip and having a plurality of dIscs thereon, the discs on one of the rolls being staggered with respect to and overlapped with the discs on the other roll, c. resilient means to bias said carriage toward a side of said strip, and d. means mounted adjacent to and adapted to project fluid under pressure toward the edges of said strip.
