Abstract
The present invention relates to a roll made of a succession of single-use absorbing paper sheets separated along at least one side thereof, perpendicular to the unwinding direction of the roll by parallel pre-cuts, the sheets being further separated by cuts extending along at least 80% of the cut side of the sheets, and the cuts and pre-cuts alternating in the roll unwinding direction.
Claims18
A roll comprising a succession of sheets of single-use absorbent paper, wherein the succession of sheets is partially defined by a first connecting region that is partially defined by a first cut arrangement, the first cut arrangement extending along at least 80% across the succession of sheets and a second connecting region that is partially defined by a second cut arrangement, the second cut arrangement extending along at least 80% across the succession of sheets, the succession of sheets including a first in-line alternation of connecting regions and cuts extending across the succession of sheets, the length of each of the connecting regions and the length of each of the cuts of the first in-line alternation of connecting regions are substantially similar, the first in-line alternation of connecting regions and cuts arranged between the first cut arrangement and the second cut arrangement in the succession of sheets.
