Abstract:
A paper roll-holder on a wall-mounting base (1), for blotting paper suitable to kitchen uses, makes easier the paper tearing, having pivotedly mounted on said base (1) two L-shaped rods (3, 4). The respective pivoting axis (3a, 4a) is parallel to the longer, transverse leg (3c, 4c) of the formed L and one (3) of said rods has at the free end of the transverse leg (3c) a short extension (3b) which is bent with right angle and directed parallel to the shorter leg (3b) of connection to the pivoting axis (3a). The rod (3) is designed to serve as a support of a paper-roll (R) and the other (4) to rest against it from above.

Abstract:
On enduit des polymères de styrène dilatables particulaires avec un produit de monoglycéride acétylé distillé, afin de réduire le temps de refroidissement de particules moulées à partir de tels polymères de styrène dilatables. On obtient le revêtement du polymère de styrène particulaire dilatable en mettant le polymère en contact avec une émulsion d'un monoglycéride acétylé distillé et de l'eau avec un tensio-actif approprié. Le monoglycéride acétylé distillé est un liquide à température ambiante et est sensiblement complètement acétylé.
Abstract:
Disclosed is a method for preparing modified cellulosic fibers comprising reacting linear, water-wettable polysaccharides with N,N'-methylenebisacrylamide under special conditions. The materials are useful in the preparation of products characterized by their increased bulk and absorbency.
Abstract:
Release coating provided by a coating composition having an acrylic functional component which has been polymerized by electron beam radiation. In a preferred embodiment the coating composition does not contain polysiloxane. In another preferred embodiment some of the acrylic functional component has one acrylic group per molecule and some has three or more acrylic groups per molecule before polymerization.
Abstract:
There is described a papermaking machine of the type wherein a web of lignocellulosic fibers is formed, and wherein the formed web is transferred to a dewatering and imprinting felt, said felt and web then passing through a nip formed by a pressure roll and a drying cylinder so as to deposit the web on the drying cylinder, said web having a dryness level between 7 percent and 35 percent as it enters said nip, characterized by the felt having imprinting yarn strands forming knuckles adjacent to the web contacting surface of the felt, the imprinting yarn strands having a spacing of about 6 to about 25 per 0.0254 meters but not significantly exceeding the average fiber length, the felt having a web facing greater than about 153 grams per square meter, and the felt having a ratio of face web in grams per square meter to the diameter in meters of the imprinting yarn strands adjacent to the web contacting side of the felt of from about 60,000 to about 600,000 wereby the web is differentially pressed onto the dryer surface. The machine of this invention is especially useful in manufacturing sanitary paper tissue and towel products.
Abstract:
Cellulosic fibers, characterized by a lack of swellability and incapable of natural fiber-to-fiber bonding, are produced by a process which comprises treating an aqueous slurry of the fibers with a formaldehyde-free polymeric compound, heating the treated fibers to cause the polymeric compound to react with the fibers, and refiberizing to separate individual, treated fibers. The fibers are useful in the preparation of improved cellulosic webs characterized primarily by their increased bulk and improved softness.
Abstract:
There is disclosed a superior method of providing a desired surface effect in a release coating on a porous sheet-like substrate by applying a coating of an electron beam radiation curable composition or material directly to one side of a base coated paper web, pressing the coated side of the substrate against a replicative surface having the desired surface effect, irradiating the coating with electron beam radiation through the substrate to cure the coating at least sufficiently to permanently adhere it to the substrate and to enable it to be removed with the substrate and with the replicated surface effect in the coating being maintained, the irradiation step taking place after sufficient time has passed to cause the coating to penetrate into the coated paper and to be in continuous intimate contact with the coated paper. Also disclosed is the apparatus for carrying out the method and the resulting product.
