发明名称 Disposable self-pleating drapes and method for making same
摘要 A disposable self-pleating drape comprises an elongated sheet of expendable material. A pleating strip extends along an upper marginal portion of the sheet and is connected in face-to-face relation to the sheet at a longitudinally series of pleating locations. At least two prong receiving openings are formed between the pleating strip and the sheet at each pleating location and are spaced apart a distance substantially greater than the distance between corresponding parallel prongs on an associated drapery hook used to hang the drape. A continuous form assembly of series connected disposable self-pleating drapes is made by continuously advancing an elongated web of disposable material, folding a longitudinally extending marginal portion of the advancing web in overlying relation with another portion of the web, and connecting the marginal portion in face-to-face relation with the other portion of the web at a longitudinal series of pleating locations to form at least two prong receiving pockets at each pleating location.
