Self-supported steam joint

The FSB 100 steam joint with stationary siphon is suitable for speeds up to 3,000 fpm with a steam pressure of 60 psi. Many older, open-gear machines may now be upgraded to stationary siphons. Also, the F Series steam joint with stationary siphon allows mills to increase production on dryer-limited machines while reducing downtime and maintenance. The balanced mechanical seal offers improved seal life—typically 2 to 4 times the current joint seal life.

Coating pigment

Mirafilm 300 kaolin-based coating pigment from Engelhard is designed for metering size press (MSP) operations. It provides a range of features, including improved print and sheet gloss, good fiber coverage at low coat weight, and excellent runnability. When compared with a 90-brightness control pigment in pilot trials, Mirafilm 300 increased sheet gloss by 5 points and print gloss by 7 points.

Roll covers

Jalon Yellow—a roll cover by Stowe Woodward—can be applied to metal cores, as well as filled rolls, for use on conventional or new generation supercalenders. Available in two hardnesses—90 and 93 Shore D—Jalon Yellow roll covers ensure long grinding intervals, damage tolerance, and a smooth surface topography. It is 0.5 in. to 0.6 in. thick and is heat resistant (Tg from 260°F to 350°F).

Turret unwind stand

Wolverine’s turret unwind stands continuously unwind paper in roll form up to 180-in.-wide. As one roll is expiring, a second roll is mounted in another position on the same unwind stand. The turret indexes the new roll into the proper unwinding position, providing uninterrupted operation. Features include heavy gauge side frames, shafts, chucks, indexing components, dancer roll tension control system, and on-machine electrical controls.

Organic micropolymers

Hercules polyflex organic micropolymers combine the qualities of an inorganic microparticle with the runnability, handling ease, and cost of conventional emulsion polymers. They deliver enhanced performance in neutral and alkaline grades without adversely affecting sheet formation. These nonsettling microemulsions do not require recirculation in bulk storage. They contain no APE surfactants and are FDA approved.

Sensor mountings

The Papermatex linear retraction assembly by Rosemount provides maximum sensor life and reduced maintenance costs to processes where cleaning and maintenance under pressure is required. When used with a timer, it eliminates routine maintenance by a plant operator and allows for a continuous process flow coupled with efficient and reliable cleaning all in one loop. When not in use, the sensor is stored in the wash port in water or in another solution.

Screen Seal

The Thermotek screen seal from Thermo Black Clawson is a mechanical screen seal designed in a new cartridge for easy installation. With no special training required for installation, the Thermotek seal saves time and reduces downtime. The cartridge design maintains the seal's integrity and eliminates the risk of cracking seal elements during installation. The design has no connection between the seal sleeve and finger so there is no risk of sleeve lock-up.

Continuous sheeting system

A new programmed continuous operation system for sheeting from Maxson allows uninterrupted production. At a preset count, the sheeter ramps down to minimum speed. When the last sheet passes through the tape section and enters the stacker, the load table automatically lowers while the tape section continues at creep speed. When the load table is in position, the sheeter returns to the previous line speed and overlap percentage.

Web tension controller

Warner Electric/Dana’s MCS 2000 digital tension control system provides a universal interface for any type of control product used in winding/rewinding, intermediate zone, and unwind applications. It operates in an open loop mode and responds to a variety of sensors for closed loop control such as load cells, dancer feedback systems, roll followers, and ultrasonics. It handles 16:1 roll-to-core ratios without external diameter sensing devices.
