Abstract: The object of the invention is a method for manufacturing in a foam medium a sheet of paper or non-woven. In the invention, the surfactant used to form the foam is a nonionic compound of an ethoxylated alcohol of the Formula I:R--(OCH.sub.2 CH.sub.2).sub.n --OH (I)wherein n is an integer from 2 to 22 and R is a linear or branched alkyl group having 6 to 20 carbon atoms or where R is in the form of R'--X wherein X is an aromatic nucleus and R' is a linear or branched alkyl group having 2 to 16 carbon atoms. In particular, the invention applies to making household papers such as paper towels.

Abstract: A dust and fiber control device for paper making apparatus is described. The device includes a wall in conjunction with a feed spout for providing a water curtain. The water curtain serves to capture and remove air suspended dust and fiber particles from ambient air. The device is positioned transversely to the motion of a paper web underneath the web between a drying cylinder and a rewinder. The water curtain device is utilized in conjunction with air flow devices for assisting in controlling the collection of air suspended dust and fiber particles from the ambient air.

Abstract: The cellulose fiber (tissue) product of the invention, such as a handkerchief or napkin, is made by combining at least two tissue plies cut into a desired format and connected to one another along a peripheral zone, and is characterized in that the plies are adhesively bonded along the perhipheral zone in such a manner that they evince a minimum delamination strength of 1 g/cm, and the peripheral zone is less than 50% of the total product surface.

Abstract: The general application of the invention is a finishing process for an air-laid nonwoven web composed of short cellulosic fibers, bound by a thermoplastic binder and having a less than perfect homogeneous fiber distribution. In the invention, the process includes deforming under hot stress the web between an undeforming hard engraved cylinder and a slave cylinder having a hardness between about 60 and 90 degrees shore hardness D. The slave cylinder is resilient and deformable at the pressure applied to it by the engraved cylinder.
