Abstract
Abstract To a roll of sheet material which is rotating on one or more drums of a cloth winder, a piece of paper is fed from below into the space between the roll of sheet material and a drum on which it is being wound, the roll being pressed against the drum. Overlapping the forward edge of the piece of paper is adhesive tape with the adhesive directed toward the roll of sheet material, and this adheres to the roll. The piece of paper is fed to surround the roll, and the rearmost edge of the piece of paper has adhesive tape overlapping it with the adhesive directed toward and bonding with a previous turn or wrap of the paper.

Claim 3
Dependent Claim
65 words
A machine of claim 1, in which the means for securing the forward edge of the piece of paper to the roll comprises means for applying adhesive tape longitudinally to the forward edge of the piece of paper extending beyond the forward edge, with the adhesive toward the roll of sheet material, said extension of the adhesive tape adhering to the roll of sheet material.
Claim 4
Dependent Claim
62 words
A machine of claim 2, which comprises means for applying adhesive tape longitudinally of the rearward edge of the piece of paper extending beyond the rearward edge, with the adhesive toward the roll of sheet material, said piece of paper wrapping completely around the roll of sheet material, said extension of the adhesive tape at the rearward edge adhering to the paper.
Claim 5
Dependent Claim
145 words
A machine of claim 1, in combination with mEans for cutting a web of paper transversely to make a succession of pieces of paper, and means for applying adhesive tape simultaneously to the rearward edge of each piece of paper extending beyond the rearward edge and to the forward edge of the web of paper adjoining each cut extending beyond such forward edge, so that when it contacts the roll of sheet material each piece of paper has adhesive tape extending beyond both its forward and rearward edges, the extension of the adhesive tape beyond the forward edge securing the piece of paper to the roll of sheet material, the piece of paper wrapping completely around the roll of sheet material, and the extension of the adhesive tape beyond the rearward edge of the piece of paper adhering to the paper to secure the wrap.
Claim 6
Dependent Claim
23 words
