Abstract: A calendering method which enhances the smoothness of surface sized paper/paperboard by a combination of temperature and moisture gradient calendering processes without the fiber sticking/picking problems that affect runnability and without using waterboxes. The moisture gradient calendering is performed so that the cross direction moisture profile can be corrected and high smoothness levels can be obtained. Heated calender rolls form a hot pressure nip having a temperature greater than the temperature of the moisturized web. Lubricant is applied to both sides of the web to prevent fiber sticking/picking in the hot nip. The lubricant may be applied by the size press, by the moisturizing showers or by separate lubricant showers. The smoothness developed by moisturizing and hot nip calendering is substantially irreversible.

Abstract: The invention relates to a process for the thermomechanical surface treatment of flat webs of material, particularly those made of paper and carton, and to agents for performing said process. According to the process of the invention, adhesion between the flat web of material and the surface of the tool used in thermomechanical surface treatment, e.g., a roll or a press, is reduced or prevented by using an abhesive agent, which contains dicarboxylic dialkyl esters and/or diisoalkyl esters of C.sub.2 -C.sub.12 dicarboxylic acids with C.sub.1 -C.sub.13 n- and/or iso-alkanols as component with abhesive effect. The abhesive agent is preferably employed as an oil-in-water emulsion and is either applied to the surface of the tool used in said thermomechanical treatment or is added to the impregnating fluid or the paper coating mass or the moistening water or the steam in pre-moistening, or is applied to the paper web after the impregnating unit or directly before the smoothing roll.

Abstract: An aqueous paper and paperboard coating composition is provided containing as a lubricant a vegetable oil triglyceride which is hydrophobic and non-ionic.

Abstract: A method for coating surgical fibers and surgical braids employing dual capillaries (10) in series.

Abstract: A decorative composite is formed by extruding a plurality of colored rods to form an elongated decorative composite article having a decorative pattern throughout defined by the individual rods. The decorative composite can be formed into decorative consumable articles, such as soap bars, deodorants, air fresheners or candy. A decorative veneer can be formed by slicing thin sections in a direction generally perpendicular to the longitudinal axis of the decorative composite article. A decorative wax veneer can be formed by employing colored wax rods. The decorative wax veneer is applied to a core to form a decorative article, such as a clear wax core to form a glowing candle. Enhanced resolution of the decorative pattern is achieved by generating an enlarged digitized image of the decorative pattern comprising a plurality of colored pixels and selecting individually colored rods in accordance with the observed colored pixels of the enlarged digitized image.

Abstract: The method comprises the application of a liquid film to a paper or paperboard rawstock web in a controlled and uniform manner to achieve a moisture gradient in the Z-direction thickness of the web to a depth of less than about one-half of the web thickness, and then pressing the treated web in at least one nip of a calender device before drying the web. The liquid application plasticizes only the surface fibers of the web so that the paper fibers at or near the surface become deformed and bonded under pressure to achieve a substantially irreversible smoothness upon being rewetted in a coating application or the like.

Abstract: A method of reducing the number or amount of chemical additives normally incorporated into paper pulp furnish before transferring the latter to the continuous wire mesh of a papermaking machine in the manufacture of paper sheet involves the use of a hydrolyzed proteinaceous foam which does not appreciably affect the degree of sizing of the finished paper sheet. The use of such foam in paper manufacture can render unnecessary the chemical treatment of effluent from the papermaking machine which is normally required to avoid environmental pollution.
