Supporting core for wound-up recording media
摘要:
A hollow-cylindrical supporting core for pancakes which is produced from recyclable plastic by injection molding is described, the arms, which may be angled off, which extend from the gating point and run to the inside diameter of the supporting core remaining in place after demolding of the injection mold and being suitable as holding grips for the supporting core.
