Abstract:
1. A winding machine for winding a thread-shaped winding material, comprising: a winding motor; a motor housing arranged on the winding motor; a motor shaft arranged on the winding motor that rotates around a shaft axis; a spool holder connected to the motor shaft; a reel arranged on the spool holder; a thread-feeding device connected to the reel that feeds the thread-shaped winding material to the reel; a positioning drive that positions the spool holder axially along the shaft axis relative to the motor housing while the motor shaft is rotating around the shaft axis, said positioning drive including a rotor, said rotor configured to rotate about the shaft axis; a control device that drives the winding motor and the positioning drive coordinately; wherein the positioning drive is arranged in the motor housing, and wherein said positioning drive rotor is configured to rotate within a thread on the motor shaft, and wherein said spool holder is configured to axially shift along the shaft axis relative to the motor housing, based on an angle of rotation of said positioning drive rotor with respect to the shaft axis, and a pitch of the thread on the motor shaft.
