Abstract
Abstract 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.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
263 words
A roll for cleaning garments or the like, comprising an elongated convoluted flexible web having an inner side, an outer side and a plurality of at least substantially equidistant transversely extending weakened portions along which the web breaks in response to the application of tensional stresses and which divide the web into a file of neighboring sections each having a leader adjacent to the preceding weakened portion and a trailing portion adjacent to the next-following weakened portion; an adhesive coat provided at the outer side of said web; a plurality of first substantially strip-shaped layers consisting of a material which does not adhere to the adhesive coat and being provided at the inner sides of the leaders of said sections so that such leaders do not adhere to the adhesive coat at the outer side of each of those sections which are in overlapping relationship therewith, the width of each of said layers, as considered in the longitudinal direction of the web, being a small fraction of the distance between two neighboring weakened portions and each of said layers extending all the way to the preceding weakened portion; and a plurality of second strip-shaped layers consisting of a material which does not adhere to the adhesive coat and being provided at the inner sides of the trailing portions of said sections so that such trailing portions do not adhere to the adhesive at the outer side of each of those sections which are in overlapping relationship therewith, said first and second layers extending transversely of said web and completely surrounding said weakened portions.
Claim 2
Dependent Claim
