A drawing machine () for drawing a tube (), defining a longitudinal axis (Y), comprising a first die () for carrying out the drawing of the tube by means of the use of a mandrel (); a device for varying the inclination () of the tube inlet into said first die (); a second die () for carrying out a skin pass operation on the tube, arranged downstream of said first die (); an in-line system for detecting the eccentricity of the tube; a data processing system () for processing signals originating from said detection system and sending input data to said device for varying the inclination () of the tube to vary the inclination of the tube so as to correct the eccentricity of the tube in-line; wherein said in-line system for detecting the eccentricity of the tube comprises a first detection head comprising at least three first transducers () arranged downstream of said first die ().

Drawing machine for drawing tubes

A peeling machine includes a rotating head installed rotating around an axis of rotation and provided with a central cavity. During use, an oblong product to be worked is disposed and a plurality of support sliders are installed thereon to support respective tools and a plurality of adjustment units configured to move the support sliders in a radial direction with respect to the axis of rotation. The peeling machine also includes a transmission unit configured to transmit motion from a first motor to the rotating head and to make the latter rotate, and also to transmit motion from a second motor to the adjustment units to simultaneously adjust the radial position of the tools.

Peeling machine for oblong products

A method or classifying metal tubes in which the measuring of the eccentricity over the entire length of the tube is provided, and in which the classification occurs on the basis of the length of the tube portions which have eccentricity either higher or lower than one or more eccentricity thresholds.

A laying head for the production of coils in hot rolling mills comprises a central body provided with a central cylinder and at least a shaped feed pipe, attached to the central body by means of clamping elements and bolts, and at least a circumferential guide disposed on the periphery of the cylindrical element. The circumferential guide consists of a plurality of elementary segments.
