Process and winding machine for winding a material web

An apparatus for winding a material web comprising:

• a reel spool;
• a carrying roll;
• said reel spool and said carrying roll positioned to form a winding nip, wherein the material web is guided over said carrying roll and through the winding nip;
• at least one contactless cutter adapted to cut a web leader during a reel spool change;
• and
• at least one separation element positioned for additionally cutting across an entire width of the material web.

A process for winding a material web comprising:

• guiding the material web over a carrying roll and through a nip formed between the carrying roll and a new reel spool;
• at least partially cutting the material web with at least one contactless cutter positioned downstream of the nip, relative to a web travel direction, during a reel spool change to form a new web leader;
• and
• additionally cutting across an entire width of the material web with at least one separation element.

• monitoring cutting by the at least one contactless cutter with a sensor;
• and
• activating the separation element when a defective cutting by the at least one contactless cutter is detected by the sensor.
