Abstract
A winding spool for a transportable package is disclosed. In one aspect, the winding spool includes a first flange and a second flange, wherein the winding core top is arranged detachably with at least the first flange at the first end of a winding core top and is connected with the second flange. The conical hollow section of the winding core top has a thin-walled configuration. The conical hollow section has a length l between the first and second flanges, and an average wall thickness t. The conical hollow section has a modulus of elasticity in the range of 1000 N/mm2 to 30000 N/mm2. An aspect ratio of l/t is selected for this conical hollow section in dependence of the modulus of elasticity. The product of the modulus of elasticity and the aspect ratio can be greater than 0.1×106 and less than 2.5×106.
