Abstract
Abstract Apparatus and method for making a multi-ply web product having at least two plies at different angles with respect to the web. An endless belt is looped helically around a cylindrical mandrel; an optional first ply is laid longitudinally along the belt. As the belt moves a second ply is wrapped helically around the first helix but at a different angle. A third ply is also wrapped around the mandrel, belt, and first ply, and this is at an angle different from the second ply. Finally, the second and third plies are cut by slitting along the edge of the belt.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
224 words
Apparatus for forming a multi-ply web product having at least two plies at different angles with each angle being acute relative to the longitudinal dimension of the web, comprising: means for moving a first flexible elongated medium helically about a generally cylindrical mandrel at an angle between about 10* and 30* between said first medium and the mandrel axis, means for depositing a second elongated flexible medium helically on said first medium while said first medium is on said mandrel, and at an angle between said second medium and the mandrel axis different from the angle between said first medium and the mandrel axis, means for depositing a third elongated flexible medium helically on said second medium while said first medium and said second medium are on said mandrel and at an angle between said third medium and the mandrel axis different from the angle between said second medium and the mandrel axis, said depositing means each including a rotatable carrier having an axis of rotation coincident with the mandrel axis and means for rotating said carriers at different speeds and in opposite directions, means for cutting at least said second medium along the edges of said first medium to produce a multi-ply web product having at least two plies at different angles within said web product and means for bonding said plies together.
Claim 2
Dependent Claim
224 words
Apparatus for forming a multi-ply web product having at least two plies at different angles with each angle being acute relative to the longitudinal dimension of the web, comprising: means for moving a first flexible elongated medium helically about a generally cylindrical mandrel at an angle between about 10* and 30* between said first medium and the mandrel axis, means for depositing a second elongated flexible medium helically on said first medium while said first medium is on said mandrel, and at an angle between said second medium and the mandrel axis different from the angle between said first medium and the mandrel axis, means for depositing a third elongated flexible medium helically on said second medium while said first medium and said second medium are on said mandrel and at an angle between said third medium and the mandrel axis different from the angle between said second medium and the mandrel axis, said depositing means each including a rotatable carrier having an axis of rotation coincident with the mandrel axis and means for rotating said carriers at different speeds and in opposite directions, means for cutting at least said second medium along the edges of said first medium to produce a multi-ply web product having at least two plies at different angles within said web product and means for bonding said plies together.

Claim 8
Dependent Claim
201 words
Method of forming a multi-ply web product having at least two plies at different angles with each angle being acute relative to the longitudinal dimension of the web, comprising: moving a first flexible elongated medium helically about a generally cylindrical mandrel at an between angle of about 10* and 30* between said medium and the mandrel axis, depositing a second elongated flexible medium helically on said first medium while said first medium is on said mandrel, and at an angle between said second medium and the mandrel axis different from the angle between said first medium and the mandrel axis, depositing a third elongated flexible medium helically on said second medium while said first medium and said second medium are on said mandrel, and at an angle between said third medium and the mandrel axis different from the angle between said second medium and the mandrel axis, said second and third mediums being wound helically about said mandrel at different speeds and in opposite directions, cutting at least said second medium along the edges of said first medium to produce a multi-ply web product having at least two plies at different angles within said web product and bonding said plies together.
Claim 9
Dependent Claim
201 words
Method of forming a multi-ply web product having at least two plies at different angles with each angle being acute relative to the longitudinal dimension of the web, comprising: moving a first flexible elongated medium helically about a generally cylindrical mandrel at an between angle of about 10* and 30* between said medium and the mandrel axis, depositing a second elongated flexible medium helically on said first medium while said first medium is on said mandrel, and at an angle between said second medium and the mandrel axis different from the angle between said first medium and the mandrel axis, depositing a third elongated flexible medium helically on said second medium while said first medium and said second medium are on said mandrel, and at an angle between said third medium and the mandrel axis different from the angle between said second medium and the mandrel axis, said second and third mediums being wound helically about said mandrel at different speeds and in opposite directions, cutting at least said second medium along the edges of said first medium to produce a multi-ply web product having at least two plies at different angles within said web product and bonding said plies together.
