Abstract: Device to form spirals in a coiling machine for trolled stock located downstream of a rolling train provided with drawing rollers, wherein the coiling machine includes a reel able to rotate around an axis of rotation, including a guide element suitable to guide the rolled stock in a segment between the drawing rollers and the coiling machine, first translating means being suitable to cooperate with the guide element to displace at least one end of the latter in a direction substantially parallel to the axis of rotation of the reel.

Abstract: Coiling machine for rolled stock located downstream of a rolling train, including a mandrel mounted rotatably around an axis or rotation on a stationary structure, the mandrel being mounted cantilevered on the stationary structure and including an inner wall orthogonal to the axis or rotation and an outer end with which a cylindrical plate is suitable to selectively cooperate, the cylindrical plate being movable from a working position, where it is arranged substantially orthorgonal to the axis of rotation so as to define a side wall parallel to the inner wall, to allow the coil of rolled stock to form and an inactive position wherein it is distanced and lowered with respect to the mandrel so as to allow the coil of rolled stock to be axially removed.

Abstract: Device to separate rolled bars (12), the bars (12) emerging from the cooling zone and being fed by conveyor means in a direction substantially transverse to the axis of the bars (12) and displaced along a plane by movement means (14), the movement means (14) being separated lengthwise, there being included a counting device (13) to form bundles consisting of a desired and defined number of bars (12), the device comprising a plurality of separator units (15) aligned lengthwise parallel to the bars (12) and each arranged between two adjacent movement means (14), each separator unit (15) comprising at least a pair of distancing pins (16), the distancing pins (16) including a first inactive position lowered and “retracted below the plane (“x”) on which the bars (12), lie and a second active position raised and protruding with respect to the plane (“x’”) on which the bars (12) lie and inserted between two adjacent bars (12), the distancing pins (16),in the first inactive positio

Abstract: Device to separate rolled bars (12) advancing on a carrier plane (11) with a direction substantially orthogonal to their axis towards a tying and/or packing zone, the carrier plane (11) comprising a plurality of movement elements (14) arranged in the direction of advance of the bars (12) and longitudinally separated, there being included a counter/spacer device (13) suitable to separate the bars (12) from each other in correspondence with a leading end segment, the device comprising a plurality of separator assemblies (10) arranged in alignment along a direction parallel to the longitudinal axis of the bars (12) and each arranged in the space between two adjacent movement elements (14), each separator assembly (10) comprising separator elements having a first inactive position arranged retracted below the carrier plane (11) of the bars (12) and a second active position wherein they are taken progressively above the carrier plane (11) and, inserting themselves between two adjacent bars (12), cause the progress

Abstract: Method to coil metal wire made of steel arriving directly from an in-line rolling plant, in which the metal wire is delivered to a rotating loop-forming head (11) cooperating coaxially with a hollow drum (12) to form the coil (13), the hollow drum (12) having a controlled rotary movement, the relative speed of the loop-forming head (11) and the drum (12) together being functional to the layer being formed, the drum (12) being associated with an alternate axial moving system.

Abstract: A method to form bundles (11) of one or more layers (20) of adjacent rolled sections (12). The method comprises discharging the rolled sections (12) from a terminal end (13a) of a transporter to cause the rolled sections (12) to fall from the terminal end (13a) onto discharge rods (14); forming at least one layer (20) of the rolled sections (12), which fall from the terminal end (13a) of the transporter (13) onto the discharge rods (14), the discharge rods (14) being arranged parallel to the transporter (13) and underneath the upper plane where the sections (12) are transported on the transporter (13). The discharge rods (14) are axially displaced with respect to the transporter (13) to define from time to time a lateral discharge space ("s") adjacent the terminal end (13a), for placing the sections (12) on the rods (14), wherein the lateral discharge space ("s") equals a transverse dimension of each rolled section (12).

Abstract: Method and device to obtain vibrations in the walls of the crystalliser (11) in an ingot mould (10) by use of actuators, the ingot mould (10) including a channel use (13) for the circulation of cooling liquid, the ingot mould (10) being associated with a conventional system of oscillation, there being induced on the crystalliser (11) vibrations of small amplitude and high frequency and acceleration obtained by exciting an actuator (16) comprising an element in magnetostrictive alloy (18) arranged in cooperation with at least one face of the crystalliser (11) itself, the element in magnetostrictive alloy (18) being excited by an electromagnetic field.
