The apparatus comprises at least one drafting device arranged anterior of knitting position for drafting fiber strips and a material feed roller pair. The material feed roller pair constitutes material feed clamping lines. A apparatus for separating the air flow rotating with the material feed roller pair from the material feed clamping lines region is provided adjacent to the material feed roller pair. A belt lace pair is provided in which the material feed roller pair can be prefixed to form shim gap with the material feed clamping lines, the apparatus for separating the rotating air flow is arranged at outer of the shim gap and can be arranged adjacent to the material feed roller pair and the belt lace pair. The apparatus can further include different mechanisms for disrupting the boundary layer of air flow on at least one roller of the roller pari. |
