Abstract
The invention relates to a method and apparatus for the treatment of continuously moving tubular fabric (1) in the wet state, in which this tubular fabric is deliberately expanded in an expansion zone (3) by blowing air in and the fabric width (WB) effectively obtained is measured. The actual value obtained for the fabric width is compared with a predetermined theoretical value and in the event that they differ a correction value is formed and the quantity of air blown into the tubular fabric is controlled as a function of this correction value. The tubular fabric (1) is expanded immediately after wet treatment and is then delivered to the expansion zone free of tension and with a sealing material store. In this way a compact apparatus is achieved which functions simply and reliably.
