摘要： A winding machine for electrical coils to be wound into layers has a device (2) which supplies a material (14) to the coil to be wound in order to separate adjacent layers of the coil from one another. The device (2) has a device (18) for producing a predetermined breaking point in the material (14), and a measuring unit (20). The measuring unit (20) determines when the device for producing a predetermined breaking point is to be activated in order to produce a predetermined breaking point in the material (14). The device also has a guide device (26) which fixes the material (14) on the coil to be wound in the vicinity of the predetermined breaking point at a predetermined time, in order to sever the material at the predetermined breaking point. The winding machine therefore anticipates when a layer change is required, in order to then produce a predetermined breaking point in the material at a distance from the coil. The predetermined breaking point is pulled through as far as the coil, and this enables the material to be guided in a controlled and reliable manner. The material is torn off at the predetermined breaking point only after the material is secured on the coil.
