In order to maintain a desired treatment atmosphere in the treatment room, a material transfer device which is free from wear and trouble and has a good sealing effect. The material transfer device has a passage element, an inlet opening of which has a variable cross-section. The cross-section is either varied by a pressure device or by internal forces in a circumferentially expansible tube. Further, a pulling device pulls the strand material through the passage element. A plurality of chambers are arranged one behind the other, through which chambers the strand material travels both towards and out from the treatment chamber. The material passages of the chambers each have locks.
