  • Patent number: 8871059
    Abstract: Processes for making fluff pulp sheets mechanically eliminate many unwanted fiber-to-fiber bonding (fiber bundles) in the sheet. Pulp slurry is deposited on a moving bottom forming wire to form a stock web. Pulp slurry is brought into contact with a moving top forming wire. The stock web is subjected to up and down dewatering creating separately formed layers to reduce fiber-to-fiber bonding. The stock web can be subjected to strong pulsating shear forces as it is being advanced along the bottom forming wire to break fiber bundles. The pulp slurry can be deposited on the bottom forming wire utilizing a headbox with dilution control to selectively adjust the concentration of the pulp slurry. Shoe presses can be used to dewater the web after it is subjected to the pulsating shear forces.

  • Publication number: 20140284893
    Abstract: A box with a wheel assembly platform has a tow strap with a folded position stowed in a recess in the platform and an unfolded position accessible outside the box. In one embodiment, the strap is incorporated in a pre-assembled handle pack positioned in the recess. The strap may be retracted by a torsion spring, and may be coiled in the pack by use of a rotating fork. In one embodiment axles projecting from rollers are supported in recesses formed in the platform, and in another embodiment the axles are supported in notches in the bottom end of cylinders mounted in cutouts in the platform. In a further embodiment a box has hand holes in opposite walls with a spacer panel providing finger access behind the holes. The platform may have hinged panels. A thermoformed skin may be applied to the platform or constitute the platform.

  • Publication number: 20140257719
    Abstract: Multiple groups of sensors are circumferentially spaced apart at each cross-directional position along a sensing roll of a nip press to measure and cancel or nearly cancel the effects of rotational variability which may be acting on the sensing roll. The strategically-placed sensors are designed to measure the pressure being placed against the web that is being advanced through the nip press. The average of the measurements of multiple sensors spaced circumferential apart provides a good cancellation of any rotational variability that might be found at a cross-directional position on the sensing roll. In this manner, a more true measurement of the nip pressure profile can be obtained and better adjustments made to reduce nip pressure profile variability. In addition, the nip variability profile may be used as a predictor of cover or bearing failures, resonant frequencies and other roll anomalies.

  • Publication number: 20140174684
    Abstract: Expandable microspheres formed by suspension polymerization using a shot growth method are provided. The microspheres are formed of a continuous, gas impermeable shell surrounding a blowing agent. The shell includes a first polymer layer formed from primary monomers and a second layer that includes a chemically reactive monomer or a high Tg monomer. To form the microspheres, the primary monomers are polymerized in a reaction vessel to an approximate 90% polymerization, at which time a secondary monomer that is either a monomer having a Tg of at least 85° C. or a chemically reactive monomer, is added to the reaction vessel to drive the polymerization reaction to completion. The outer layer thus contains either a larger amount of the high Tg monomer or a chemically reactive monomer that possesses the ability to covalently bond a cationic species. The microspheres may be used in papermaking processes to increase the paper bulk.
