Title: Continuous web winding method and device with suction-induced winding start of empty core mandrels

Abstract: A method is disclosed for winding a continuous web of material on a core mandrel, the winder comprising a cutter that actuates to provide a new end of web material. The cutter itself comprises a source of vacuum for creating an airflow around a new core mandrel between the mandrel and a guide wall which extends around at least one fourth of the mandrel surface, the airflow causing the new web end to follow the mandrel around and tuck said new end between the mandrel circumference and the tensioned web extending between the new mandrel and upstream equipment.
