Abstract: A process for thermoforming a discrete section of an amorphous pliable thermoplastic sheet in a temperature-controlled thermoforming mold to provide a discrete thermoformed section having one or more discrete shaped articles formed therein and to heat the shaped articles to a temperature below the Tm but above the Tg of the polylactic acid polymer in the sheet to induce crystallization of the polylactic acid polymer in the shaped articles. While unconstrained by the thermoforming mold, the discrete thermoformed section is tempered at a temperature such that the polylactic acid polymer in the shaped articles achieves a degree of crystallization of at least about 5% (as measured by X-ray diffraction) to thereby increase heat resistance of the shaped articles.

Abstract: The present invention relates to a process for applying optical brightening agent (OBA) to a sheet of paper or paperboard substrate. The process comprises the step of spraying an aqueous composition comprising an optical brightening agent onto at least one surface of a sized paperboard substrate to form a treated paperboard substrate. The treated paperboard substrate includes a layer of OBA on at least one surface of the paper or paperboard substrate in which the brightness of the treated paper or paperboard substrate is greater than the sized paper or paperboard substrate before treating thereof.

Abstract: An apparatus for folding box blanks into completed boxes includes a feeding station having a swing guide assembly designed to provide an abutting surface which makes contact with flaps/panels of the box blank as the box blank is feed from the feeding station into a folding station. The swing guide assembly can be synchronized with a feed assembly which moves box blanks from a hopper assembly to a first feed position. Actuating drives operating at different speeds can be used to move the box blanks from the feeding station to a first and second folding station. Critical actuating motions used in the process of folding and advancing the box blanks can be performed at a different speed than other non-critical actuating motions.

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.

Abstract: A refining member for a pulp refiner comprising a refining body with a refining surface comprising refiner bars separated by refiner grooves and teeth. Each of the refiner bars extend from a radially inward position on the refining surface to a first radially outward position on the refining surface, and the teeth extend to a second radially outward position on the refining surface. The second radially outward position is nearer to an outermost part of the refining body than the first radially outward position. The refiner bars are adapted to refine wood fibers, and the teeth are adapted to break up fiber bundles.

Abstract: A refining member comprising a refining body with a refining surface comprising first and second refiner bars separated by first and second refiner grooves, respectively. The first refiner bars extend from a radially inward position to a first radially outward position. The second refiner bars extend to a second radially outward position that is nearer to an outermost part of the refining body than the first radially outward position. The second refiner bars have a longitudinal length from about 0.6 cm to about 10 cm. The first and second refiner bars have a respective first and second maximum height extending upward from a floor of a respective, adjacent first or second refiner groove. The second maximum height is at least 0.35 mm less than the first maximum height. The first refiner bars are adapted to refine wood fibers and the second refiner bars are adapted to break up fiber bundles.
