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.
