ABSTRACT:
An apparatus for continuous drying and shrinking of textile knitted or woven good incorporates at least one drying station that includes several oppositely disposed and oppositely hot-air nozzles which are offset relative to each other and directed into a through-channel defined thereby. At least upper and lower endless rotating, porous guide belts limit the channel above and below. An endless rotary web-tentering frame passing along the through-channel limited by the guide belts conveys a web of material to be treated through the at least one drying station, wherein a first vertical distance between the frame and a lower strand of the upper guide belt and a second vertical distance between an upper strand of the lower guide belt are defined such that, as the apparatus operates, within a predetermined effective range of a hot-air nozzle directed thereon, a web, in a locally limited area, secured in and conveyed by the webtenter frame, comes into contact with a portion of a corresponding guide belt, whereby the lower and/or upper guide belt moves at greater speed than that of the tenter frame. A supply mechanism for conveying the web to be treated to the tenter frame includes a device for securing the material with forward slip to the tenter frame.
