Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
117 words
A cluster mill for rolling articles such as strip, sheet or the like, comprising upper and lower work rolls; upper and lower bearing rolls for applying forces for rolling; a set of intermediate rolls comprising at least one combination of upper and lower first intermediate rolls in contact with said work rolls and at least one combination of upper and lower second intermediate rolls in contact with said bearing rolls; said work rolls and intermediate rolls being longer than the width of articles to be rolled therein; said second intermediate rolls being undercut from the ends thereof toward the roll''s center to provide a force-transmitting surface substantially equal to the width of said article to be rolled.
Claim 2
Dependent Claim
117 words
A cluster mill for rolling articles such as strip, sheet or the like, comprising upper and lower work rolls; upper and lower bearing rolls for applying forces for rolling; a set of intermediate rolls comprising at least one combination of upper and lower first intermediate rolls in contact with said work rolls and at least one combination of upper and lower second intermediate rolls in contact with said bearing rolls; said work rolls and intermediate rolls being longer than the width of articles to be rolled therein; said second intermediate rolls being undercut from the ends thereof toward the roll''s center to provide a force-transmitting surface substantially equal to the width of said article to be rolled.
Claim 3
Dependent Claim
28 words
