Abstract
Abstract A pattern roll is provided for use in opposition to a sonic horn for fusing responsive material interposed between the roll and horn. The pattern of the roll is formed integrally on the roll body in a manner that provides a much more serviceable roll and one in which the pattern possibilities are greatly increased in relation to pattern rolls of this sort heretofore available.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
103 words
An improved pattern roll for use in opposition to a sonic horn for fusing heat responsive material interposed between said roll and horn, said pattern roll comprising a cylindrical body having discrete horn opposing elements projecting from a continuous base rib raised at the surface of said body, said elements and base rib being integral with said body and following a predetermined and independently selected pattern as to course of said base rib and cross-sectional shape and spacing of said elements, said horn opposing elements are finished at an even projecting height and with a projecting face curvature concentric with the roll axis.
Claim 2
Dependent Claim
103 words
An improved pattern roll for use in opposition to a sonic horn for fusing heat responsive material interposed between said roll and horn, said pattern roll comprising a cylindrical body having discrete horn opposing elements projecting from a continuous base rib raised at the surface of said body, said elements and base rib being integral with said body and following a predetermined and independently selected pattern as to course of said base rib and cross-sectional shape and spacing of said elements, said horn opposing elements are finished at an even projecting height and with a projecting face curvature concentric with the roll axis.
Claim 3
Dependent Claim
32 words
An improved pattern roll as defined in claim 1 wherein the horn opposing elements for a pattern repeat lengthwise of the roll body are spaced for opposition at a single sonic horn.
Claim 4
Dependent Claim
19 words
An improved pattern roll as defined in claim 1 wherein said horn opposing elements taper from said base rib.
Claim 5
Dependent Claim
46 words
An improved pattern roll as defined in claim 3 wherein said base rib is raised sufficiently on said roll body to provide an aggregate height of base rib and horn opposing elements sufficient to accommodate interposed material readily between the roll and an opposed sonic horn.
