<p>A roll of convoluted crepe paper, thin plastic foil or like web material has an outer side which is provided with a continuous coat of adhesive, transversely extending uniformly spaced weakened portions in the form of perforations or slits, and layers of a material which does not adhere to the adhesive. Such layers are applied to the inner side of the web so that they flank the weakened portions and allow for rapid engagement of the leader of the web by two fingers when the user wishes to remove one or more sections or panels between neighboring weakened portions. The roll can be used for the cleaning of garments or for analogous purposes. The length of each layer, as considered in the longitudinal direction of the web, is a small fraction, preferably less than one-third, of the distance between two neighboring weakened portions.</p> |
