CORE-WINDING TUBE
Document Type and Number:
WIPO Patent Application WO/2018/152782
Kind Code:
A1
Abstract:
Disclosed is a core-winding tube, comprising a tube body (1) for winding material (4). The outer surface of the tube body is provided with a step portion (2) along the axial direction thereof. The height of the step portion is equal to the thickness of the material. A cutter groove (3) is provided on a side, close to the axial centre of the tube body, of the step portion. An elastic clip (5) for clamping the material is fixedly provided in the cutter groove, the upper end of the elastic clip being connected to an opening on one side of the cutter groove, and the lower end thereof being inclined towards the other side of the cutter groove. The core-winding tube positions a cutter by means of the cutter groove being added, and the elastic clip firmly clamps the cut material in the cutter groove, not only ensuring the splicing of the material and the step portion, but also having a good fixing effect, and thereby preventing the appearance of folds and creases during the process of winding the material.
