Abstract
An apparatus, including a manifold pipe, for applying variable amounts of steam to sections of a calenderable material to control certain properties of the material such as gloss. Built-in steam flow control valves are provided along the manifold pipe to control the amount of steam applied to each section. Bucket nozzles provided on the valves decrease the velocity of the steam jetted from the valves and eliminate any condensate present in the steam before discharging the steam against a surface of the calenderable material. Condensate which may form on the apparatus may be channeled away from the calenderable material by a pair of gutters.
