摘要

The spinning point of an air-spinning machine, comprises a roller pair arrangement containing a drawing gear (28) and a spin box (20) arranged in spin direction with a fiber supply channel (26). A casing is arranged on the discharge side of the roller pair of the roller pair arrangement and is fixed to the spin box. The casing partially comprises the roller pair in an area of gussets. The roller pair is a discharge roller pair (32) and the casing is arranged between the fiber supply channel of the spin box and the discharge roller pair that consists of different radii. The spinning point of an air-spinning machine, comprises a roller pair arrangement containing a drawing gear (28) and a spin box (20) arranged in spin direction with a fiber supply channel (26). A casing is arranged on the discharge side of the roller pair of the roller pair arrangement and is fixed to the spin box. The casing partially comprises the roller pair in an area of gussets. The roller pair is a discharge roller pair (32) and the casing is arranged between the fiber supply channel of the spin box and the discharge roller pair that consists of different radii. The contour of the casing extends over the total width of the roller pair. The contour is concavely formed in the area of the fiber supply channel and has a ring sector in the cross-section form and a radial distance of 1.5-3 mm of the roller of the roller pair. The ring sector consists of an opening angle of 25-150[deg]. The spin box is so formed that it forms the casing.
