ABSTRACT:
Easy starting rolls of perforated tissue product which have a reduced tendency to ply separate are formed with an adhesively secured doubled over tail tab folded against the roll. The strength and location of the bonds are controlled by controlling the penetration of the adhesive into the tissue. The dry tensile strength of the projecting folded over tail tab exceeds 400 g/3″ and the caliper thereof exceeds one mil The adhesive bonds are spaced away from lines of perforation joining sheets in the initial sheets of the roll.
