Abstract

Abstract A method and apparatus for forming more than one shape in a material wherein a first group of pairs of opposed rollers are arranged to impart a first shape to the material and a second group of pairs of opposed rollers following the first group are arranged to impart a second shape to the first-shaped material. One roller or each pair of the second group being readily releasable and conjointly movable away from the other associated roller of each pair to a non-shaping position to alternately form only the first shape or the first and second shapes in the material. A roller bending arrangement at the inlet end bends the material with a coil set against the coil set to a substantially flattened condition prior to contact with the first and second groups of rollers to reduce the tendency thereof to buckle or ripple during the shaping thereof.

Claim 8
Dependent Claim 220 words
In apparatus for forming a coiled material with a coil set into more than one desired shape, the combination comprising: support structure means; bending means supported by the support structure means for bending the coiled material as it unrolls from the coil against the coil set to a substantially flattened condition, a first group of pairs of opposed shaping rollers supported for rotary movement on the support structure means, said first group of pairs of rollers being shaped to impart a first shape to the material upon being progressively passed between successive pairs thereof; a second group of pairs of opposed shaping rollers shaped to impart a second shape to the first-shaped material upon being passed between successive pairs thereof; and a pair of opposed support members supporting the ends of a plurality of rollers of said second group to move said plurality of the lower rollers of the second group between an upper operative position and a lower retracted position spaced from the other associated roller of each pair of said second group to allow the material with the first shape to pass between the opposed rollers of each pair of the second group without altering the shape thereof whereby to alternately form the first and second shapes in the material or only the first shape in the material.
Claim 9
Dependent Claim 61 words
In apparatus as set forth in claim 6 wherein said bending means includes a bending roller positioned adjacent the inlet end of the shaping Rollers arranged so that the material passes in a reverse direction away from the shaping rollers back around the bending roller and then passes toward the shaping rollers to bend against the coil set in the material.
Claim 10
Dependent Claim 74 words
In apparatus as set forth in claim 6 wherein said bending means includes a first bending roller positioned adjacent the inlet end of the shaping rollers and a second bending roller above the first bending roller, the bending rollers being arranged so that the coiled material passes around the second roller and reverses back around the first roller and again reverses toward the shaping rollers to bend against the coil set in the material.
