Patent ID: 8151615

Claim:
A profiling machine for forming U, C and Z profiles, comprising: an initial profiling unit comprising two parallel initial fixed shoulders, a plurality of initial profiling rollers being supported by the two parallel initial fixed shoulders; and a final profiling unit comprising, a first final fixed shoulder inclined in relation to a vertical plane, a plurality of first profiling stations being supported by the first final fixed shoulder, each first profiling station comprising pairs of first profiling rollers, and a second final shoulder, a plurality of second profiling stations being supported by the second final shoulder, each second profiling station comprising two pairs of second profiling rollers, the first and second final shoulders having opposing planar faces, wherein the second final shoulder is hinged on a longitudinal axis to enable passing from, a first position for forming Z profiles, in which longitudinal planes along the planar faces are mutually parallel, and, for each opposing first and second profiling stations, the first profiling rollers are symmetrical with a first one of the two pairs of the second profiling rollers about a longitudinal axis of the final profiling unit, to a second position for forming C and U profiles, in which longitudinal planes along the planar faces lie at an angle to each other and, for each opposing first and second profiling stations, the first profiling rollers are symmetrical with a second one of the two pairs of second profiling rollers about a vertical longitudinal plane of the final profiling unit, wherein rotational axes of the first profiling rollers are disposed in vertical planes spaced from vertical planes in which rotational axes of the second one of the two pairs of the second profiling rollers are disposed.
