<p>A suction drum dryer (10, 11), for knitted fabrics (14) and the like, is provided with an adjustable width bellows mechanism (22) for masking side margins of the drums not occupied by the fabric web. Ambient air drawn into the suction drums (10, 11) is thus caused to flow substantially exclusively through the material to be processed. Significantly improved operating efficiencies are realized, as well as significantly higher production output from a given piece of equipment.</p> |
