Abstract
The tensioning machine serves for a heat treatment of lengths of material which are guided widthways, particularly textile material. Two tensioning chains convey the lengths of material in the usual way through an inlet zone, a plurality of heat treatment zones and an outlet zone, and the advancing and returning strands of the tensioning chain are supported and guided in chain guide rails. In order to cool the tensioning chains very effectively and thereby to be able to prolong the operational life of the high-temperature grease which is used, cooling air blowing arrangements by which the used cooling air can be introduced into the heat treatment zones as preheated fresh air are associated with the long sections of the chain guide rails running inside the heat treatment zones.
