Abstract: The invention provides a dryer for a printer such as a print on demand wallpaper printer. The dryer has a compartment with an opening across the top. The opening is in a path of a moving media web which is printed on by the printer. The opening is optionally covered by a door. A source of heated air is located above the opening and blows heated air downwardly onto the door, or the opening if the door is open. In general, the door covers the opening and acts to support the web when the door is closed. When the door is open, the moving web can enter the compartment.

Abstract: A double backer for curing the web bonding adhesive and drying the corrugated paperboard web utilizes a web holddown apparatus for maintaining the web in intimate drying contact with the lower heating units which does not require the use of a driven holddown belt. The holddown is provided instead by a series of parallel, flexible, closely spaced strips suspended above the web in the heating section and extending in the direction of web travel. Supplemental holddown force may be provided by banks of spring fingers supported above and in contact with the holddown strips on a transverse support rod which may be rotated to vary the amount of supplemental holddown force. Alternately, the holddown strips may comprise continuous cables in which one run of the cables rests upon the moving web to provide the web holddown and a second run includes high friction cable portions which are movable into driving contact with the upper surface of the web to pull it through the heating section, as for initial web thread up.

Abstract: In the case of an arrangement for the continuous heat setting of yarns, which are guided by means of transport belts into, and then out of, a heat setting chamber using superheated steam, at least one central mast is provided which is equipped with several circulating transport belts, arranged in polygonal form when viewed in cross section. At least one yarn is wound around the central mast and the transport belts in controlled loops. The transport belts are themselves subdivided into circulating belt sections, which are arranged consecutively at transfer points, the transfer points being arranged directly upstream and/or downstream of the heat setting chamber.
