Paper web coating assembly - has a deflection roller between two drying cylinders to bridge the gap if web is not to be treated

摘要

The assembly to give a selective processing action of a running web of paper or cardboard, or allow the web to pass through without any action, at least one deflection roller is in the intermediate zone between two neighbouring drying cylinders (46,49) of a final drying group, which is max. two drying cylinder dias. The deflection roller bridges the gap in the event that the web is not to be treated by spreaded unit (3,3'). At least one further deflection roller (19) is in this zone as a guide for the web, below the spreader (3,3'), which is above the intermediate zone between the drying cylinders (46,49). USE/ADVANTAGE - The assembly is for online processing of running paper or cardboard webs, such as coating pigmenting, applying an adhesive and the like, and to determine whether the action is not to be applied. The structure gives a diverting path away from the coating station, without much space, simply installed to give a short run.
