Abstract
Self-gripping devices having a base with a plurality of the gripping element attached are disclosed. The gripping elements are capable of releasably self-gripping fibrous materials without damaging same include a stiffly rigid stem with at least one flexible self-gripping means attached thereto. The self-gripping means can be one or more retaining nibs integral with or attached to the stem and are generally inclined downward so as to offer relatively little resistance upon penetration into a fibrous material and greater resistance to pulling out.
Claims11
A self-gripping device for engagement with fibrous materials comprising a base sheet and a multitude of bristle-like gripping elements mounted in dense profusion in all directions over the surface of the base sheet, the said gripping elements comprising a stiffly rigid stem of constant cross sections and a plurality of flexible retaining nibs for retaining fibers or fiber bundles of fibrous materials, said nibs arranged one above the other on said rigid stem, each of the said retaining nibs attached in transverse orientation to the said stiffly rigid bristle-like stems and bending towards said base sheet, a plurality of said stems passing into a fibrous sheet and being secured thereto such that the nibs thereof engage said fibrous sheet.
Self-gripping device of claim 29 wherein said base sheet comprises a surface and said gripping elements extend from either of the sides of the two surfaces with the base sheet.
