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
100 words
The method of forming a pattern roll for use in opposition to a sonic horn for fusing heat responsive material interposed therebetween, which method comprises preparing a mill for a predetermined pattern of discrete horn opposing elements projecting from a base rib, applying said mill to a roll body for partially raising said pattern at the roll body surface, coating the partially raised pattern with a resist and etching the roll body to the base of the pattern rise, and then repeating the mill application and etching steps until the predetermined pattern is fully raised at the roll body surface.
Claim 2
Independent Claim
100 words
The method of forming a pattern roll for use in opposition to a sonic horn for fusing heat responsive material interposed therebetween, which method comprises preparing a mill for a predetermined pattern of discrete horn opposing elements projecting from a base rib, applying said mill to a roll body for partially raising said pattern at the roll body surface, coating the partially raised pattern with a resist and etching the roll body to the base of the pattern rise, and then repeating the mill application and etching steps until the predetermined pattern is fully raised at the roll body surface.
Claim 3
Dependent Claim
27 words
The method of forming a pattern roll as defined in claim 1 wherein said roll is rotated during application of the mill thereto for raising said pattern.
Claim 4
Dependent Claim
39 words
The method of forming a pattern roll as defined in claim 1 wherein the projecting faces of the fully raised horn opposing elements are abraded to an even projecting height and with a curvature concentric with the roll axis.
Claim 5
Dependent Claim
27 words
The method of forming a pattern roll as defined in claim 3 wherein, after fully forming and abrading the raised pattern, said roll body is chrome plated.
