Abstract
Apparatus for crimping filaments using turbulent heated fluids to which the filaments are exposed in two treatment chambers connected to one another. The first treatment chamber is constructed in two parts, the parting plane between the two parts is stepped and the filament guide means are intersected by the parting plane. The filaments are easy to introduce and the operating temperature need not be reduced in the event of any filament breaking.
