The present invention is directed to a device for the continuous tension-free treatment, such as drying, shrinking, finishing and the like, of textile fabric sheets so that the sheets can be lifted upwardly from a transport belt in at least onetreatment zone by directing jets of air from below across the full width of the sheet. The fabric sheet is conveyed from one treatment zone to another in the transport direction in a gathered condition. At least one lower nozzle, extending transverselyof the transporting direction, is located below the transport belt and is connected with a compressed air source. A closing member is arranged for selectively opening and closing the lower nozzle. A separating walls are positioned above the lowernozzle and above the transport belt and the walls extend transversely relative to the transport direction with adjacent separating walls defining a treatment zone.
