US 4,142,393 A · Profiling machine

Abstract

A machine for shaping elongate strips, especially of metal, into a variety of profiles comprises a cascade of working stations in which the strips are subjected to progressive deformation between rollers, some or all of which may be driven to advance the strips along their transport path through the several stations. Each working station has an annular or star-shaped carrier, rotatable on a support about a horizontal axis, with a plurality of peripherally spaced roller mountings adapted to hold a pair of coacting rollers, the various roller pairs on each carrier being differently shaped to produce a selected profile upon being brought into an operating position -- e.g. horizontal on a level with the axis -- by rotation of the carrier. The operatively positioned roller pair can be coupled with a drive mechanism, individual to the respective station or common to all working stations, for positive rotation thereby.

Dependent claims

A machine for profiling flat elongate workpieces by progressive deformation of their cross-sections, comprising:

a plurality of cascaded working stations disposed along a transport path and provided with shaping means engageable with a workpiece to be profiled, at least one of said working stations comprising a stationary support having an at least partly ring-shaped body on an axis parallel to said transport path and an annular carrier coaxial with said support encompassing said transport path, said carrier being rotatably held on said support and being fitted with a plurality of peripherally spaced, inwardly extending roller mountings selectively placeable in an operating position in line with said transport path by rotation of said carrier, said shaping means including differently contoured roller pairs respectively held on said mountings for potential engagement with a workpiece arriving over said transport path;
and
drive means for advancing said workpieces along said transport path.

Dependencies are inferred from the claim text.
