摘要： A longitudinally extending web of lofty nonwoven abrasive surface treatment material is provided in a coreless roll form to the end user. Successive wraps of the nonwoven abrasive material have interengaging surfaces sufficient to maintain the material in a spirally wrapped configuration yet being readily separable. A plurality of longitudinally spaced and laterally disposed perforations through the web permit the user to successively separate the web into a plurality of sheets of abrasive surface treatment material. In a preferred embodiment, the roll is encased in a protective shrink wrap sheath, and each sheet is separated from the roll by separating said sheet from an innermost wrap of the roll. In another preferred embodiment, the abrasive surface treatment material includes abrasive particles of 1000 grade of finer.
