The single-faced corrugated board is fed across the bridge to the bridge guide and bridge brake before it is bonded in the glue unit. An even bonding requires a smooth, shock-free and accurate supply of the corrugated web as well as consistent paper web tension. A number of guide, transfer and tension rolls allow the daily production of several hundred-thousand meters of paper web. At this point, only one cylinder bearing failure can result in downtime and production delays. LUBCON bearing lubricants for the use in corrugated machines feature good temperature resistance, high load carrying capacity and protect cylinder bearings permanently against wear, even at high speeds.
