摘要： A roll of masking material comprising a coiled elongate thin flexible sheet, which sheet has longitudinal folds defining, in some embodiments with elongate edges of the sheet, edges of longitudinally extending portions of said sheet. Those longitudinally extending portions of the sheet include pleat-like portions of the sheet each having opposite major surfaces generally parallel with the axis of the roll, which pleat-like portions are superimposed major surfaces to major surfaces to form a laminate with outermost ones of the superimposed pleat like portions defining the opposite outer surfaces of the laminate. At least some of the edges of the superimposed pleat like portions are positioned generally radially aligned at the first end of the roll, and the longitudinally extending portions of the sheet further including a first radial portion extending radially along the radially aligned edges at the first end of the roll from the edge of one of the outermost pleat like portions at the first end of the roll, and a first distal portion having one of the elongate edges of the sheet and extending for a short distance along the outer surface of the laminate toward the second end of the roll from the edge of the first radial portion opposite the outer most pleat to which the first radial portion is attached. If the sheet has longitudinal edges they may be separably attached, having been formed by longitudinally scoring a tube of the sheet material during manufacture of the roll. Also, a large percentage of the folded sheet can be positioned adjacent one end of the roll to facilitate cutting it on a dispenser.
