  • Publication number: 20070235578
    Abstract: A winding machine has a pay-off unit for unwinding a single- or multiple-end type wire material, a feed bobbin, and an optional take-up unit for rewinding the wire material onto one or more bobbins. The pay-off unit is associated with a wire guide device having a motorized carriage, which can slide along the axis of motion, and has an arm that rotates with respect to the carriage and is equipped with an idler wheel onto which material unwound from the feed bobbin is wound. An angular position sensor detects the inclination of the arm with respect to the carriage and a control unit governs the carriage movements as a function of the signals provided by the sensor. The optional winding unit features at least one take-up device with a gripper to grasp an end of the wire material and actuators to reduce the gripping force of the gripper during winding.
