Rod holders (sometimes called rod beds) are used to evenly support the metering rod across the entire face width of the web during the coating process. Without support across its entire length, the metering rod would not remain straight during operation and it would be impossible to maintain a consistent coating weight across
the width of the web.
Buschman rod holders are used in paper mills all over the world, in all types of coating machines. We offer the longest lasting, best fitting metering rod holders in the industry for every coating application and machine type.
The stability, durability, and quality of Buschman rod holders is unmatched. We are the only metering rod manufacturer in the world that manufactures our own Hot Cast Polyurethane (PU) rod holders and UHMW Polyethylene (PE) rod holders in our own facility under one roof. We have the unique capability to control ALL aspects of production and quality to deliver the precision required from today’s papermaking industry.
Our proprietary in-house manufacturing and machining process produces rod holders and rod beds that give the metering rod a more uniform and consistent fit along the entire length of the holder. Our rod holders reduce rod vibration, increase rod and holder life, and promote a more uniform coating.
Buschman can engineer and manufacture custom rod holders to your exact specifications. We can also manufacture standard rod holders for any machine, including but not limited to:
- Valmet (Metso)
- Black Clawson
Buschman rod holders are available in UHMW Polyethylene and Hot Cast Polyurethane. Some of the material differences include:
|Hot Cast Polyurethane (PU)
||UHMW Polyethylene (PE)
|Available in lengths up to 11.58 meters (456’)
||Available in lengths up to 11.58 meters (456’)
|Casting provides a high level of consistency and accuracy between orders
||Precision machining allows for nearly infinite customization to the holder profile
|Soft rod cradle conforms to the threads to create a seal and prevent leakage
||Harder rod cradle can act as a scraper blade, keeping the rod cleaner in operation – especially for smooth rods
|Softer material minimizes vibration
||Harder material is rigid, offering a lower coefficient of friction over traditional PU material
|Available with antifriction additives which offer superior wear characteristics over traditional PU
