Winding machine for web-type materials and method for operating such a winding machine

A winding machine for web material, comprising:

• a feeding device;
• and
• at least one winding shaft which is capable of being driven and designed to receive a winding core for winding of the web material,
• wherein the winding machine is allocated a system for regulating and/or reducing an electrostatic charge of the web material during the winding process;
• wherein the winding machine further comprises a cross-cutting device for cutting through the web material during or at an end of a winding process and/or during or at a start of a turning procedure, wherein the cross-cutting device can be displaced or pivoted relative to the winding core accommodated by the at least one winding shaft;
• wherein the cross-cutting device is allocated an applying device for laying a new web material start onto an empty winding core accommodated by the at least one winding shaft, wherein the applying device comprises an electrostatic discharging/charging device associated with the system for regulating and/or reducing the electrostatic charge;
• and
• wherein the electrostatic discharging/charging device of the applying device is configured to selectively electrostatically discharge the web material wound onto the winding core accommodated by the at least one winding shaft, wherein the electrostatic discharging/charging device comprises:
• an active positive electrode array comprising one or more active needle-like individual positive electrodes, and which is electrically connected to a positive high-voltage source during operation of the electrostatic discharging/charging device;
• an active negative electrode array comprising at least two active needle-like individual negative electrodes, and which is electrically connected to a negative high-voltage source during operation of the discharging/charging device;
• and
• a sensor electrode array comprising at least two needle-like individual sensor electrodes, and which is electrically connected to a ground during operation of the discharging/charging device.
