WEB DRIER

摘要

A drier for sheet-shaped photographic web materials has a housing in which first and second transport rollers are located for engaging the web at opposite major surfaces thereof to advance it in a predetermined path. One or more blowers with associated heating devices are provided for blowing warm air towards one of the major surfaces of the web. Perforated sheet metal walls establish adjacent this one surface intermediate the same and the blowers a pressure chamber which extends at least substantially over the cross-sectional area of the housing and which in the direction of flow of the airstream or airstreams has a dimension substantially smaller than its dimensions transversely to this direction. Thus, warm air enters the chamber from the blower or blowers and leaves it in direction towards the major surface of the web substantially evenly distributed over substantially the entire cross-sectional area of the housing.
