Apparatus for producing a spun yarn |
摘要 |
For producing a yarn (4) spun from a loose fibre array (2) using a vortex flow an apparatus is used in which between a fibre supply duct (1) and a yarn take-off tube (5) a vortex chamber (3) is provided. Into the vortex chamber (3) a fluid is injected via tangentially oriented nozzles (6), which subsequently is drained via an exhaust duct (7). This apparatus comprises a wall limiting the vortex chamber downstream zone formed e.g. by a wall plate (20). This plate separates the vortex chamber (3) from the exhaust duct (7), but for completely draining the fluid is provided with a plurality of openings (21) extending to the exhaust duct (7). Owing to the functional separation of the vortex chamber (3) from the exhaust duct (7), in which the inventive apparatus differs from the state of the art, the fibre losses are reduced.
