Abstract
A winding machine for electrical coils to be wound into layers has a device which supplies a material to the coil to be wound in order to separate adjacent layers of the coil from one another. The device has a device for producing a predetermined breaking point in the material, and a measuring unit. The measuring unit 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. The device also has a guide device which fixes the material 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.
