1. A web processing system for processing a processed continuous web of material into a plurality of folded sheets, comprising:
- a web handling arrangement;
a cutting arrangement, the web handling arrangement supplying a processed continuous web of material to the cutting arrangement, the cutting arrangement cutting the processed continuous web of material into a stream of sheets, the cutting arrangement includes a knife roll;
a first folding arrangement downstream from the cutting arrangement configured to receive sheets from the cutting arrangement and form first folded sheets, the first folding arrangement includes counter-rotating first and second folding rolls;
a second folding arrangement downstream from the cutting arrangement configured to receive sheets from the cutting arrangement and form second folded sheets, the second folding arrangement includes counter-rotating first and second folding rolls;
a first lap roll operably positioned between the knife roll and the first folding roll of the first folding arrangement; and
a second lap roll operably positioned between the knife roll and the first folding roll of the second folding arrangement;
whereinone of the first and second folding rolls of the first folding arrangement includes a tucker and the other one of the first and second folding rolls of the first folding arrangement includes a gripper that operatively cooperates with the tucker to fold the first sheets; and
one of the first and second folding rolls of the second folding arrangement includes a tucker and the other one of the first and second folding rolls of the second folding arrangement includes a gripper that operatively cooperates with the tucker to fold the second sheet.

Abstract
A web processing system is provided. The web processing system supplies a processed continuous web of material to a cutting arrangement. The cutting arrangement forms sheets from the continuous web of material. The sheets are then supplied to multiple folding arrangements such that a single web of material is used to supply sheets to multiple folding arrangements.
