Abstract: Webs can be embossed using matched embossing elements with shoulders located off-centered. Such a configuration increases the bulk of the web and maintains the web's strength. The shoulder of one roll is located above or below the embossing surface mid-plane. The shoulder of the second roll substantially matches the off-centered elements of the first roll.

Abstract: An improved system for embossing a pattern on an absorbent consumer paper product such as a paper towel includes a first pair of embossing rollers that are patterned to impress a relatively fine preparatory base pattern onto the web, and a second pair of embossing rollers that are patterned to impress a final pattern onto the web. The final pattern is of a type that would cause bursting of the absorbent paper web if the absorbent paper web was passed through the second pair of embossing rollers without first being passed through the first set of embossing rollers. As a result, the formation of the preparatory base pattern by the first set of embossing rollers creates stretchability in the absorbent paper web that enables the final pattern to be impressed thereon by the second pair of embossing rollers without bursting the absorbent paper web.

Abstract: An improved method, and resulting product, for creping a web of papermaking fibers by adhering the web to a creping dryer and with a creping blade removing the web from the creping dryer which provides increased absorbency with less reduction in strength. The improvement comprises reducing the cohesive forces between the fibers to a greater extent than reducing the adhesive forces between the web and the creping dryer accomplished by applying a fluid at least primarily comprising water overall to the side of the web away from the creping dryer in sufficient quantity and at a position to accomplish the improved results. The method is particularly useful in the practice of wet creping wherein the web is creped from the creping dryer at a dryness of from 45% to 60%.

Abstract: An embossed sanitary paper product and method of making such product. The paper is embossed to form in the paper a midplane and an array of bosses extending up and down from the formed midplane. Each upward extending boss is flanked on two sides, in each of two directions, by a downward extending boss, and in at least one of the two directions, the paper between an upward extending boss tip and an adjacent downward extending boss tip on one side has a higher strain than the paper between the upward extending boss tip and an adjacent downward extending boss tip on the opposite side. The forming of a higher strain region and a lower strain region on opposite sides of a boss can be accomplished by forming asymmetric bosses with each upward extending boss rotated 180.degree. about an axis perpendicular to the plane of the paper with respect to its adjacent downward extending bosses.

Abstract: The reaction rate of the process for making nonlinear polyesters, i.e., conventional alkyds, is accelerated by using relatively large proportions of solvent, e.g., 15-50% by weight of an aromatic or ketonic high boiler, and, optionally, an esterification catalyst, e.g., tin oxalate. The process results in alkyds having more evenly distributed molecular weights with significantly reduced reaction times and at lowered reaction temperatures with consequent energy savings.
