Abstract: A shear for cutting and simultaneously conveying one or more pairs of rolling wires or bars includes a mobile diverter with at least two channels in each of which a wire or bar slides and at least two pairs of counter-rotating knives, each pair of which acts upon the wire or bar to produce cut segments of wires or bars. The cut segments of wires or bars are then conveyed by a conveying device including at least one pair of mobile elements that may be configured to move independent of each other and to be synchronized with each other and with the mobile diverter for facilitating insertion of each of the cut sections of wires or bars into an output channel of at least two pairs of output channels, each pair of output channels corresponding to one of the mobile diverters.

Abstract: The single shear described herein for cutting and simultaneously conveying one or more pairs of rolling wires or bars (1, 2), comprises the following parts: a mobile diverter (5) consisting of at least two channels (6, 7) in each of which a wire or bar (1, 2) slides; at least two pairs of counter-knives (3, 4) each of which acts on a wire or bar (1, 2); a conveying device (9) for conveying the cut segments of wires or bars (1, 2), comprising—at least one pair of mobile elements (20, 20?) configured to be independent of each other and synchronized with each other and with the mobile diverter (5), for the separate management of each of said cut sections of wires or bars (1, 2), and—at least two pairs of output channels (A1, A2, B1, B2) for conveying the cut segments of wires or bars (1, 2).

Abstract: The single shear described herein for cutting and simultaneously conveying one or more pairs of rolling wires or bars includes a mobile diverter consisting of at least two channels in each of which a wire or bar slides. The single shear further includes at least two pairs of counter-knives, each of which acts on the wire or bar, and a conveying device for conveying the cut segments of wires or bars. The conveying device may include at least one pair of mobile elements configured to be independent of each other, but configured to be synchronized with each other and with the mobile diverter for the separate management of each of said cut sections of wires or bars. The single shear may finally include at least two pairs of output channels for conveying the cut segments of wires or bars.

Abstract: An apparatus (1) for cooling a bar (10) comprising: —an outer casing (3), —a passageway (2) defining a crossing direction (X) for the bar (10), —at least one drum (4) comprising a plurality of cooling lines (6) each having at least one respective through cavity (9) parallel to the crossing direction (X) and a respective cover (15) which can move between an open position and a closed position, the drum (4) being accommodated in the casing (3) and rotational about a rotation axis (Y) to move the cooling lines (6) between an operating position (11), in which the cavity (9) is aligned with the passageway (2), and at least one resting position (12), in which the cavity (9) is separated from the passageway (2), the casing (3) being shaped so as to touch and hold the respective cover (15) in the closed position when the cooling line (6) is in the resting position (12).

Abstract: A laying head for forming coils using continuous and substantially rectilinear rolled products such as rods or wire, having vibration damping means integrated in one of two rotor supports (3), preferably the one on the rolled product outlet side. Said means comprise a plurality of coils (6, 6?, 6?) arranged around the rotor (3), rotating about its axis (X), which generate a magnetic field actively controlled by a computer, the resultant force of which is perpendicular to the axis (X) and of a predetermined intensity so as to eliminate the inertial forces generated by the mass imbalances. Alternatively, the damping means incorporated in one of the supports are comprised of oil film bearings.
