Enclosure having a controlled atmosphere for the continuous treatment of textile yarns deposited on a continuous conveyor belt outside the enclosure and transported by the conveyor belt through the enclosure. The enclosure is at least partially sealed and includes an inlet and an outlet which are traversed by the conveyor belt, each having a sealing head with rollers, in which each sealing head includes at least one lower roller and an upper roller which are positioned transversely and across from one another below and above the conveyor belt, respectively. The sealing head is arranged to have a biasing force exerted by one of the rollers in the direction of the other in a manner so as to tighten the conveyor belt and yarns that it carries between them. The biasing arrangement includes at least one hydraulic jack connected to a hydraulic pressure source via a control and adjustment device.
