Spool for receiving winding material and spool part system

Abstract

A spool is provided for receiving winding material, having a rotationally symmetrical, in particular conical, spool core for receiving the winding material, wherein the spool core has a first end and one or more first latch areas, and a first flange comprising one or more first latch elements. In order to enable the first flange to be mounted on the spool core as reliably as possible and with a simplified construction, one or more second latch areas are provided on the first end of the spool core and one or more second latch elements are provided on the first flange, wherein the second latch areas are formed on the spool core and the second latch elements are formed on the first flange, such that the second latch elements engage with the corresponding second catch areas when the first catch elements are engaged with corresponding first latch areas.
