Patent number: 10569987Abstract: 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.Type: GrantFiled: September 23, 2015Date of Patent: February 25, 2020Assignee: SAMP S.P.A.

Patent number: 10011456Abstract: 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.Type: GrantFiled: April 3, 2015Date of Patent: July 3, 2018Assignee: SAMP S.P.A.
