Abstract
A texturizing device for a yarn conditioning plant comprises a stuffer box, which is made from one piece. The cross section of the stuffer box channel is circular and predominantly constant; however, a taper and/or a yarn retarding lid can be arranged at the exit end of the stuffer box channel. In order to attain a crimping effect when the production is started, the stuffer box comprises at least one air inlet opening, which leads into the stuffer box channel, and which is directed against the channel inlet opening.
