ABSTRACT:
Apparatus is described for preventing web weave from occurring at the exit from a corrugator bridge wherein a single face corrugated board is being drawn from the bridge by a glue machine. The single face web may be present on what is termed the upper bridge or the lower bridge and control is maintained by providing a friction plate faced with canvas which is biased against the single face web as it is traveling over an exit guide roll. Typically, a single face board is produced on a corrugator in widths of 80 to 86 inches and the friction plate is less in length than half the width of the paper. The drag force is regulatable by an operator adjustment of air pressure being delivered to biasing air cylinders.
