ABSTRACT:
A storage device for filamentous material formed by a base sheet and a cover sheet. The base sheet has a vertical row of peaked or arched slots and the cover sheet a corresponding number of horizontal slots. The slots in the base sheet define parallel ribbons and the slots in the cover sheet define horizontal ribbons. The cover sheet is secured to the base sheet by spot-welding. The peaks of the base sheet ribbons are welded to the horizontal ribbons and the sheets are welded at the sides to form thereby a partition defining intermediate pockets for the filamentous material.
