Apparatus for the manufacture of aluminum strip conductors

Claim 1

In an apparatus for reshaping the edges of an aluminum strip conductor wherein said strip is moved from a supply roll to a recoil roll while said edges are pressed by a plurality of grooved reshaping rolls, said apparatus including a base frame, at least one pair of reshaping roll assemblies mounted in opposing fashion on said base frame and movable thereon toward one another to press said strip therebetween; the improvement wherein said at least one pair of reshaping roll assemblies comprises a first pair of reshaping roll assemblies, each of the rolls of which have therein a V-shaped groove with angles of 1*30* above and below the horizontal center line thereof; and a second pair of reshaping roll assemblies, each of the rolls of which have therein a U-shaped groove with angles of 1*- 20* above and below the horizontal center line thereof; and forming an arc at the apex thereof having a radius of from 0.05- 0.7 mm. at a predetermined distance from the edge of said roll; each of said reshaping roll assemblies comprising slide means mounted on said base frame for movement in a direction transverse to the movement of said strip, a lower block mounted on said slide means and movable in said direction, fluid pressure means operably connected to said lower block for sliding said lower block in said direction, a stud bolt pivotally mounted in said lower block and extending upwardly therefrom, an upper block attached to said stud bolt and mounted above said lower block, said rolls rotatably mounted on said upper block, whereby said rolls of each of said reshaping roll assemblies may be selectively pressed against said edges of said strip.
