Width machine modification description – to respond to market needs.
In the dry-end section the shrinkage of the format has been obtained by occluding both sides sections of TAD honeycomb, TAD rolls and Yankee hoods. The pressure roll covering in the same way has been adapted for the new width. In the-wet end the shrinkage was obtained only by mounting narrower formation wire - 3100 mm.
