Abstract

Tenter driers are frequently used for drying textile webs whose edges have an increased weight per unit area or have been treated with glue. It is extremely difficult to dry the edges to the same degree of residual humidity as the remainder of the web. In the inlet region, the blower box has been replaced by blower pipes extending parallel to the chain rails. The pipes are connected to the recirculated air system of the drier and provided with nozzle apertures directed towards the web edges. Since only a low drying capacity is available, the drier either has to be extended or the throughput speed has to be decreased. With the drier according to the invention, a longitudinal section which starts at the inlet and extends over at least 20% of the total length is equipped with blower pipes (27, 28) aligned parallel to the chain rails (13, 14). Blower boxes (18, 19) are also mounted in this longitudinal section, both above and below the textile web (15). In order to feed drying medium to the blower pipes (27, 28), an additional blower (32) which is connected to a blower box (18) in the inlet region (1) is provided.
