摘要

A device, for separating the paper from the cores of rolls or logs of paper or similar products, which is based on a combination of a mandrel that receives trimmings from a roll or log where the mandrel has an outer diameter that is less than the inner diameter of a core of at least one log. The mandrel is provided with at least one axial recess that is directed along several contiguous generatrices of the mandrel. Above the axial recess is arranged a circular rotating blade which cuts both said trimmings the core.
