Abstract: The operation of paper machines making light weight webs at higher speeds wherein satisfactory drying of the webs is frequently precluded by the occurrence of web flutter within the drier section, is made possible by the provision of floater headers integrated with the hood structure of the Papridrier (T.M.), to provide support to the web substantially throughout its length until a sufficient degree of dryness is reached whereat the web is sufficiently strong to withstand flutter generated forces.

Abstract: Disclosed herein a web-treating system equipped with web-threading apparatus having as principal structure, pulleys in endwise coaxial relation with web-conveying rolls, an endless drive cable extending over the pulleys, and a web-tail gripping device with transversely elongate elements thereof supported in the web path by the drive cable. Such elements and the pulleys are especially constructed to engage in an interlock condition as the elements traverse portions of the web path around the rolls so as to prevent the elements from centrifugally swinging away from the web path.

Abstract: Apparatus for treating webs, such as found in pulp dryers, consisting essentially of elongate housings aligned transversely of a web path and having dispensing apertures for air or other fluid and feed openings arranged with respect to the apertures to direct the air perpendicularly toward the web path. Disclosed also are housings having duct means for returning the air dispensed by the housing to an air circulation system.
