Abstract
A coil-forming head, defining a longitudinal axis, for forming coils of a substantially rectilinear metallic product, comprising a fixed supporting structure, a rotor, adapted to turn about said longitudinal axis and rotatably fixed to said supporting structure, wherein the rotor comprises a bell-shaped member, which expands outwards with respect to said axis and has an outer surface thereof provided with at least one spiral-shaped groove, dimensioned to convey and form coils of a metallic product having diameter from 5 to 8 mm, and comprises at least one spiral-shaped tube, arranged inside and integrally fixed to said bell-shaped member, and dimensioned to convey and form coils of a metallic product having a diameter from 8 to 25 mm, wherein feeding means are provided to feed the product to said at least one groove or to said at least one tube.
Claims5
A coil-forming head, defining a longitudinal axis X, for forming coils of a substantially rectilinear metallic product, comprising
- a fixed supporting structure,
- a rotor, adapted to turn about said longitudinal axis X and rotatably associated to said supporting structure,
- wherein the rotor comprises
- a bell-shaped member, which expands outwards with respect to said longitudinal axis X and has an outer surface thereof provided with at least one spiral-shaped groove, dimensioned to convey and form coils of a metallic product having a first diameter,
- and at least one spiral-shaped tube, arranged inside and integrally fixed to said bell-shaped member, and dimensioned to convey and form coils of a metallic product having a second diameter greater than said first diameter,
- wherein there are provided feeding means to feed the metallic product to said at least one groove or to said at least one tube.
