Abstract
An off line apparatus for converting a rolled web into a fan-fold web and method of fan folding a web is described. The apparatus has a creasing station capable of receiving the web at a feed rate. The creasing station has a first die roller, wherein the first die roller comprises a first blade and a first cushion, and a second die roller. A coupling mechanism synchronizes rotation of the rollers such that the first blade engages the second cushion and the second blade engages the first cushion during one each rotation. A reader determines the location of a gap between the labels. A controller receives the location of the gap from said reader and communication with a drive mechanism to adjust the rotation rate such that the first blade and the second cushion engage.
