Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
100 words
Apparatus for aligning a travelling sheet of material against a reference edge (23:41) parallel to the direction of sheet travel, comprising a first roll (21:36) skewed towards the reference edge in the direction of sheet travel, and a mating roll (22:35) on the opposite side of the sheet travel path, one of the rolls being driven and the coefficient of friction of the first roll being greater than that of the mating roll, characterised in that the mating roll (22:35) is skewed oppositely to the first roll (21:36) away from the reference edge (23:41) in the direction of sheet travel.
Claim 2
Dependent Claim
