Abstract
In order to be able to operate chambers for the continuous fluid treatment of textile yarns and which comprise several chamber parts with an improved sealing effect, even at elevated pressures and temperatures when aggressive fluids are used, one or both sealing faces of superimposed sealing face pairs undergo shape correction. The shape correction opposes the elastic deformation undergone by the sealing faces when loaded under operating conditions.
