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.
Claims3
A storage device having pockets for receiving filamentous material, said device being formed by a base sheet and a cover sheet, said base sheet having formed therein at least one vertical row of arched cuts, said cover sheet having formed therein spaced horizontal cuts corresponding in number to each arched cut formed in said base sheet, said cover sheet being superposed over said base sheet and being secured thereto at at least one point adjacent each peak of each of said arched cuts and between said horizontal cuts of said cover sheet to form pockets to receive filamentous material suitable for storage, and said device further including vertical welds between said base sheet and said superposed sheet and laterally of said arched cuts to form lateral boundaries to said formed pockets.
A storage device having pockets for receiving thin filamentous articles, said device being formed by a base sheet and a cover sheet, said base sheet having formed therein at least one vertical row of peaked cuts to form peaked ribbons, said cover sheet having formed therein spaced horizontal cuts corresponding in number to said peaked cuts formed in said base sheet, said cover sheet being superposed over said base sheet and being secured thereto at at least one point along each of said peaked ribbons and between said horizontal cuts of said cover sheet, and being further secured by vertically disposed weldings adjacent the ends of said horizontal cuts and laterally of said peaked cuts to form pockets to receive said filamentous articles for storage.
A storage device having pockets for receiving filamentous material, said device being formed by a base sheet and a cover sheet, said base sheet having formed therein at least one vertical row of arched cuts, said cover sheet having formed therein spaced horizontal cuts corresponding to said arched cuts formed in said base sheet, said cover sheet being superposed over said base sheet and being secured thereto at at least one point adjacent the peak of each of said arched cuts and between said horizontal cuts of said cover sheet, and said base sheet and said cover sheet being further secured to each other vertically adjacent the ends of said arched cuts to form lateral boundaries to pockets formed between said horizontal cuts and said arched cuts.
