Rod beds are characterized by three attributes: reliability, performance and reusability. By reliability we mean better and more stable runnability for your process. Performance includes long a lifetime with excellent results. Reusability means less waste and significant cost savings.
Significant cost savings
We divide our huge selection of rod beds into three main groups by their material and design. Polyurethane (PU) rod beds, polyethylene (PE) rod beds and insert rod beds.
Read about the performance of Valmet Rod Beds below in terms of paper quality, lifetime and cost effectiveness - with five stars the highest performance and one the lowest.
|Rod Bed||Description||Paper quality||Long lifetime||Cost efficiency|
|Rod Bed PU||Excellent profitability in smooth rod coating and superior tolerance against impurities in recycled fiber process|
|Rod Bed PE-UHMW||Long lifetime in virgin fiber grooved rod process|
|Rod Bed PE-insert||The most cost-effective rod bed type|
To compareValmet Rod Bed PU and a competing PE rod bed, we monitored the coat weight profiles in a customer’s machine with a two-sided film sizer. The coat weight was 8 g/m²/side.
The results proved Valmet Rod Bed PU’s excellent profitability – the basis weight profiles at the PM reel were much better than peaky profiles competing in the PE rod bed.
The excellent tolerance of Valmet Rod Bed PU against impurities from recycled fibers leads to increased lifetime for rod beds and therefore decreased costs.
It was shown in a customer’s machine that Valmet Rod Bed PU could be reused four times after the grooved rods have been worn out, leading to a six-week average lifetime for Valmet Rod Bed PU. At the same time, the average lifetime of competing PE rod beds was less than four weeks. The annual costs of rod beds decreased by 36%.
