Abstract:
A method monitors/controls unwinding and supplying thread from a supply device to a textile machine. The supply device includes a control unit and a thread collection and supply unit moved by a motor. A first sensor detects first data indicative of a current driving torque applied to the collection and supply unit. A second sensor detects second data indicative of a current tension value of thread supplied to the textile machine. A first indicator representing driving torque values is calculated, each variation of the first indicator representing a variation of the driving torque value to compensate for a deviation of the first data. A second indicator is calculating representing tension values applied to the thread supplied to the textile machine. Each variation of the second indicator representing a deviation of the second data. Based on the indicators, malfunctions in the unwinding and supply of thread are detected and signaled.
