Abstract: In a method for treating ropelike textile goods in a closed container that contains at least two axially adjacent J-boxes for receiving textile goods during at least part of the treatment time, a driving motion in a feeding direction is imparted to the textile goods, by means of a gaseous flow of feeding medium made to act on the rope via feed nozzle means. The textile goods, before entering each J-box, pass through separate feed nozzle means assigned to that J-box. Upon exiting from these feed nozzle means, the textile goods are introduced selectively into the respective associated first J-box or a second J-box adjacent to this J-box, or in the case of at least one J-box are conducted along a predetermined path, which carries the textile goods away from this J-box.

An annular groove extending between the conical faces has an end facing away from the combustion chamber which acts as a sealing edge upon contact of the valve sealing face with the valve seat. Recesses embodied in the valve seat and/or on the valve sealing face hydraulically connect the annular groove with a portion of the second conical face located on the combustion chamber side of the annular groove.

The rope emerging from the feed nozzle means is lapped, on entering a J-box located in the treatment tank, by the feed nozzle means itself, which execute a reciprocating motion.
