Abstract: In a spiral steamer, the deflecting rollers are arranged in the lower areas of the individual windings of the spiral in such a way that the fabric web approximately follows a chain line.

Abstract: The treatment device includes a container for a treatment fluid, in which a drum around which the web loops rotates eccentrically. The drum is made up of axis-parallel, hollow, sealed rods and possesses a drum shaft structured as a hollow shaft, which together produce a buoyancy which makes up a significant part of the weight of the drum and the drum shaft. The drum is suspended at one end via stretchably elastic drive belts, and at the other end on tension springs, which catch the remaining weight. The drum shaft is eccentrically mounted on an eccentric shaft. The eccentric shaft is provided with equalization weights. All of the measures act together to allow low-vibration operation, towards the outside, of the treatment device.

Abstract: A wide jet nozzle for applying a bath to a substrate such as a textile web. The nozzle has a housing made of bent sheet metal upon which a discharge port is formed by two bent nozzle lips which lie parallel to one another, extend in the longitudinal direction of the housing, and define a discharge jet plane. A single feed conduit is provided which discharges transversely to the jet plane into the housing. Further provision is made in a plane transverse to the longitudinal direction of housing and intersecting the axis of section, adjacent to housing, of feed conduit for at least three deflection surfaces, one after the other in the direction of flow, which are generally transverse to the local direction of flow and off of which the flow is able to be deflected in each case by 90.degree..
