Abstract
Disclosed are folded configurations in coiled sheets enabling formation of masking sheet rolls for improved dispensing and unfolding, in combination, with adhesive tape securable to a walled surface.
Claims4
A folded roll of thin and flexible masking material having a longitudinal axis and first and second folded end portions axially spaced from each other along the longitudinal axis, the folded roll of masking material comprising:
- opposing, first and second outermost layers extending in a direction of the longitudinal axis between the first and second folded end portions;
- a slit formed in the first outermost layer, the slit defining first and second elongated edges in the first outermost layer;
- a first radially extending end portion extending between the first and second outermost layers at the first folded end portion;
- a first intermediate layer immediately adjacent the second outermost layer, the first intermediate layer and the second outermost layer directly connected at a first fold formed at the second folded end portion;
- a second intermediate layer immediately adjacent the first outermost layer;
- and
- a third intermediate layer disposed between the first and second intermediate layers, the third intermediate layer directly connected to the first outermost layer at a second radially extending end portion at the second folded end portion;
- wherein the second intermediate layer is longitudinally between the first and second radially extending end portions.
