Abstract
The stretching chamber arrangement comprises a stretching chamber with a first closeable feed conduit, a return conduit, a liquid container and a pump for the circulation of the liquid through the stretching chamber. For premoistening the yarns to prevent dry friction during the start-up of the arrangement, a second feed conduit is provided which by-passes the closing valve of the first feed conduit and which opens out into the yarn duct through small premoistening openings situated in the direction of the yarn travel in the area of the yarn entrance in front of the first yarn guiding element of the arrangement.
