Abstract

A yarn treatment chamber for thermal treatment of a running yarn, with a center zone, in which a pressurized hot, gaseous or vaporous medium acts on the yarn, and end zones on both sides of the center zone, in which a cooling, gaseous medium is active. The end zones have a yarn inlet or outlet openings with a yarn sluice, which seals the associated end zone and the yarn treatment chamber. The yarn inlet and outlet openings (2, 3) are arranged such that the yarn (14) must change direction, and the yarn treatment chamber (21 has yarn deflection means (12) to guide the yarn (14) between the yarn inlet and outlet openings (2, 3). Both the yarn sluice (23A) and the yarn sluice (23B) are accessible without problems to operating staff at an ergonomically favorable height below the yarn deflection means (12) of the yarn treatment chamber (21).
