Forming Systems

A forming system comprises of devices and equipment that support and remove the water throughout the development of the web of paper until it reaches a state that will allow it to transfer to a pressing stage.  There are two types of forming systems, High-Resolution™ and FC Former™.

Forming products are the devices and equipment that support and remove the water throughout the development of the web of paper until it reaches a state that will allow it to transfer to a pressing stage. Forming products consist of forming boards, foil blades, deckles, deckle boards, wear surfaces, low vacuum units, high vacuum units, and top formers.

High Resolution™ Forming System

The High-Resolution forming system is designed for use with packaging grades of paper. This three-component system consisting of high-resolution drainage structures, Stepfoil™ technology, and high precision vacuum control provides the papermaker with excellent activity control across broad grade structures and different furnishes while maintaining an open sheet. The simple system with no moving on machine parts provides a robust and reliable system that increases table dewatering capacity and sheet activity control with a low total cost of ownership.

When equipped with consistency profiling ability, the Octopus stock approach system allows the control of CD basis weight profile while paper machines are operating.
  • Drainage Structures

    Drainage Structures

    Drainage structures are vital to water removal during the papermaking process. We provide drainage structure including forming boards, gravity foils, VID™ forming technology, and high vacuum single or multiple zone flatboxes.
  • Vacuum Control Systems

    Vacuum Control Systems

    Vacuum control systems provide efficient use of energy and precision control of the wet end dewatering process. We offer a complete range of vacuum control components including DCS vacuum interfaces, vacuum control piping systems, single-stage or multiple stage exhausters, and vacuum control valves.
  • Wear Surfaces

    Wear Surfaces

    Wear surfaces are one of the most overlooked papermaking components at the wet end. Forming board, gravity and vacuum assisted blades, and flatbox covers that resist wear and maintain their original shape over extended periods of operation ensure that the paper machine has optimum dewatering and activity performance. We offer ceramic and polyethene wear surfaces.

  • Multiple-Barrel Pressure Filter
Multiple-barrel pressure filters are designed to remove contaminants from a liquid filtration process while providing high cleaning efficiency, low flow restrictions, and easy maintenance.

ErGo™ Filtration System

The ErGo filtration system removes contaminants from a variety of applications including process water and fresh water. End results include the protection of shower nozzles and process equipment along with improved product quality. The “bottomless” barrel design provides easy element removal and cleaning. The ergonomically engineered system allows easy and safe access when changing filter elements. The filter is available with both internal and external backwash options.

MegaFlo™ Backwash System

The MegaFlo system can be designed with either internal or external backwash. Flow enters through the bottom inlet header and is distributed equally through each filter barrel. As contaminants build on the exterior filter screen, the differential pressure increases and backflushing occurs. A backwash system operates identically to the internal backwash system with an additional header at the top of the unit to introduce a secondary source of clean backflush fluid.

RapidKleen™ Auto-Strainer

RapidKleen™ Auto-Strainer
The RapidKleen auto-strainer is a high volume fresh water pressure filtration system.
The RapidKleen auto-strainer introduces the fluid to be strained to an inlet nozzle located in the lower shell section of the vessel. Contaminated fluid is directed to a filter assembly. The filter bundle captures particulates from the bottom and top entrances by way of the hollow core of the assembly. Cleaned fluid exits the unit through the outlet nozzle positioned in the shell housing between the top and bottom tube sheets of the filter element. The system backwashes automatically to clean the filter elements when the differential pressure switch setpoint is reached without interrupting the process flow.
