ABSTRACT:
Articles to be dried are conveyed through a tentering frame in a path. Air is heated and then directed into contact with the articles in direction transversely of the path. The air is directed by at least one crossflow blower unit and a plurality of channel elements, each of which has a foraminous wall which faces the articles passing through the frame. The blower is driven by a motor drive which is operative for circulating the heated air in direction through the blower unit and into the channel elements. Thereupon, the air passes through the respective foraminous walls to impinge against and thereby dry the articles. After impingement, the air is guided away from the articles by a plurality of air outlet passages which are respectively formed between adjacent ones of the channel elements which are successively arranged along the path at a predetermined spacing from each other. Each outlet passage has a relatively narrower cross-section closer to the path, and a relatively wider cross-section further from the path.
