Abstract (en)

An apparatus, comprising two parallel connecting rods (1) oscillating around a lower horizontal axis (X) and each having a fork (2) at the upper end to accommodate the mandrel (3) of a coil (4) constantly pressed peripherally against a winding roller (5), and a device to regulate the nip pressure between the coil (4) and the winding roller (5), comprising a control unit (6), which processes, according to a pre-determined algorithm, the signals coming from a linear potentiometer (9) that measures the movements of the connecting rods (1) with respect to a reference position, to obtain signals indicative of the actual weight of the coil, which are used to control a hydraulic actuator (7) that regulates the pressure of the connecting rods (1).
