SPOOL FILLED WITH MULTIPLE ELONGATED ELEMENTS WOUND CLOSELY TOGETHER

摘要

A spool (10) filled with two or more elongated elements (14, 16) such as steel cords wound in parallel and in several windings upon the spool is provided. The distance s between two neighboring elongated elements, as measured along a line parallel to the axis (18) of the spool (10), is not more than 10 mm along 90 % of the length of each elongated element. The advantage is that unwinding problems such as sags and downstream processability problems are avoided.
