## Abstract

The invention is directed to a method of expanding the width of an embossing roll which is composed of two or more embossing sleeves. Spacer washers are positioned between the sleeves to provide an embossing roll of the desired width. The outer edge of the spacer washers are then shaped to the pattern of the embossing sleeves so as to blend the pattern on the edge of one embossing sleeve to the pattern on an adjacent edge of another embossing sleeve.

## Claims

### Claim 1

A method of expanding the width of at least two or more embossing sleeves mounted on an embossing mandrel, comprising the steps of:
(a) assembling said sleeves on said mandrel with a washer positioned between each of said sleeves, said washer having a thickness equal to a fraction of the width increase that one desires to expand the embossing roll, with each said washer having a diameter greater than the maximum diameter of the embossing sleeves, and
(b) cutting and shaping the outside edge of each washer to a contour pattern so that there will be a blending of the pattern from the edge of one sleeve to the edge of the other sleeve there the two sleeves are spaced apart by a washer with the surface of the washer shaped to provide the blending of the two patterns.
