  • Patent number: 10569987
    Abstract: A method for implementing a correct winding of a wire on a spool. The method is characterized in that it comprises a step for calculating the angular speed of a motor displacing a wire dispensing device according to the wire winding pitch and according to the pulling error, detected in relation to a given pre-set set-point and to a tolerance value, in order to determine the presence of a possible “valley error”, or of a possible “peak error”. Furthermore, if during the spool winding a “valley error” or a “peak error” is detected, the control device decides whether to slow down or to increase the speed of the wire dispensing device with the aim of filling the valley or of skipping the peak.

  • Patent number: 10480044
    Abstract: A resistance annealing furnace for annealing a metal wire, strand, string, wire rod or strap having at least two electric axes provided with respective pulleys to convey the metal wire and a DC voltage generator suppliable with an AC voltage to generate an annealing voltage applied between the two electric axes so as to provoke the annealing due to Joule effect. The DC voltage generator has active supplying means supplied with the AC voltage so as to generate an intermediate DC voltage, a pulse width modulator to transform the intermediate voltage into a first PWM voltage with the same amplitude, a voltage transformer to transform the first PWM voltage into a second PWM voltage with a smaller amplitude, and a voltage rectifier stage to transform the second PWM voltage into the annealing voltage.

  • Patent number: 10011456
    Abstract: Method for implementing a correct winding of a wire on a spool (100). The method also comprises a step for calculating the angular speed of a motor (43) displacing the wire dispensing device (40) according to the wire winding step and according to the dancer error, detected by a position sensor (35) that provides an analogical signal with respect to a zero position and to a tolerance value, in order to determine the presence of a possible “valley error”, or of a possible “peak error”. In this method, if during the spool winding, a “valley error” or a “peak error” is detected, the control device decides whether to slow down or to increase the speed of the wire dispensing device (40) with the aim of filling the depression or skipping the peak.
