Abstract:
1. A device for treatment of a traveling yarn with a steam-creating medium, comprising: a column of several chambers provided with yarn inlet- and yarn outlet-channels and arranged one over the other, of which one of the chambers is a steam treatment chamber provided with a steam inlet and a condensate outlet; and mixing chambers respectively operated upstream and downstream of the steam treatment chamber, each mixing chamber respectively having an air inlet and a condensate outlet, the yarn inlet- and yarn outlet-channels of the steam treatment chamber having an opening cross section that, on the one hand, makes possible a pneumatic yarn threading-in and, on the other hand, controls the exchange of air and steam between the chambers such that a steam-air-mixture atmosphere sets in that substantially forecloses the entrance of air into the steam treatment chamber, and the steam-air-mixture atmosphere being controlled by regulation devices that regulate the steam- and air-supply into the steam treatment chamber or, respectively, into the mixing chambers, wherein the air inlet in the mixing chamber downstream of the steam treatment chamber includes a jet terminating in the vicinity of the yarn travel path to which are connected protection plates.
