Patent ID: 7255030

Claim:
Method for longitudinal cutting of a running, unseparated web in at least two web portions, wherein the unseparated web ( 2 ) is printed in a high-speed printer ( 1 ), and wherein the unseparated web ( 2 ) is cut longitudinally in at least said two web portions ( 2 a , 2 b ) by means of a cutting mean ( 7 ), characterized in that the unseparated web ( 2 ) is brought to run between a first and a second edge support ( 8 , 9 ) such that longitudinal outer edges ( 2 d , 2 e ) of the unseparated web ( 2 ), extending in the running direction (T), can cooperate with said edge supports ( 8 , 9 ), that at least when the width (B) of the unseparated web ( 2 ) varies and/or changes, this variation and/or change is read, and that the second edge support ( 9 ) and the cutting means ( 7 ) are continuously controlled to move in a lateral direction (S) relative to the running direction (T) of the unseparated web ( 2 ) and in dependence of said continuously read variations and/or changes of the width (B) of the unseparated web ( 2 ), such that incorrect cutting of the running, unseparated web ( 2 ) is avoided if the width (B) thereof varies and/or changes.
