The Octopus™ stock approach system is a radial-type distributor that supplies forming devices (vats, hydraulic formers or headboxes) with uniform paper machine profiles across the width of the machine without the need for header balancing by recirculation.

When equipped with consistency profiling ability, the Octopus stock approach system allows the control of CD basis weight profile while paper machines are operating. The profile management tool permits the papermaker to minimize variations, improve sheet properties, and increase profitability.

Drainage structures are used to remove water during the papermaking process. Drainage structures are a combination of components that may include forming boards, gravity foils, VID™ forming technology, and high vacuum single or multiple zone flatboxes.

A vacuum control system provides efficient use of energy and precision control of the wet end dewatering process of a paper machine. The V1000™ vacuum control system components include DCS vacuum interfaces, vacuum control piping systems, single-stage or multiple stage exhausters, and vacuum control valves.

Durwear polyethylene wear surfaces are in direct contact with a paper machine’s clothing. Each Durwear grade is formulated to give a distinct set of characteristics. All are manufactured to ensure critical blending, extrusion, and machining standards are continuously monitored.

How long does a wear surface last?

Paper machines demand high-quality durable ceramic wear surfaces also known as foil blades, forming blades, or drainage elements to meet the everyday challenges of production. Ceramic wear surfaces provide the support on the drainage structures in the forming and pressing sections of a paper machine.

How long does a wear surface last?

A hybrid wear surface uses a combination of Durwear polyethylene and a premium Ultrawear™ ceramic wear surfaces.

Blade holders position the doctor or roll cleaning blade firmly against the roll, accommodate roll surface irregularities, facilitate rapid blade changes, and, within limits, compensate for thermal expansion.

Doctor & Roll Cleaning Blades

A ceramic tip creping blade is used in tissue production to add bulk, stretch, absorbency, and softness. A doctor or creping blade holder is used to load the blade against the Yankee, the heart of the tissue-making process. A ceramic tip creping blade helps create a smoother surface, which can lead to a finer crepe and better handfeel.

Unlike other ceramic creping blades, CeraEdge™ creping blades break in quickly and have a no-chip ceramic tip, making them an optimal choice for providing long life for tissue machine productivity. The CeraEdge S blade is recommended for applications where tissue softness is the main priority. The CeraEdge L blade is recommended when maximizing blade life is priority. Both CeraEdge blades provide stable performance for tissue production, are safer to the Yankee surface than traditional ceramic blades, and produce less dusting and linting due to a smoother wear edge.

The Ultra C doctor blade is designed for applications that require extended life and a blade to conform to the roll surface at lower pressure for cross-machine flexibility.

The Ultra C doctor blade's unique design is recommended for doctoring ceramic, granite, and composite press rolls, dryers, and calender rolls. It maintains a clean, sharp edge with low pressure and provides excellent chemical resistance, low friction, long blade life, and enhanced machine direction strength for reduced energy consumption and effective sheet shedding.

A doctor blade will only effectively clean a roll’s surface if its leading edge remains strong enough. The nanotechnology-enhanced resin matrix is engineered to increase the longevity of the blade and its leading edge. Kadant Research & Development experts have engineered nanotechnology-enhanced doctor blades for rolls where the removal of contaminants is particularly challenging and extended blade life is required. Longer life translates directly to fewer blade changes and lower operating costs while maintaining the cleaning function necessary for machine efficiency.
