matched rigid and resilient rolls having complementary

mated or matched rolls afford a number of benefits including

Grupe, which discloses a web production method
having much in common with the methods disclosed by
Schulz `671 and Thomas, also teaches that

the concept of matched embossing rolls can be extended to
rubber rolls. As a result, any combination of
steel/rubber or rubber/rubber matched embossing rolls is
