Abstract

An open end spinning device has a spinning cup to which discrete fibres are fed through an annular feed channel defined between the inner surface of a fixed, pref. trumpet shaped feed duct arranged with its large dia. mouth in the mouth of the spinning cup and pref. correspondingly shaped centre-body arranged co-axially in the feed duct, whereby the fibres are fed to all regions of the fibre collecting surface of the spinning cup. The centre body may be secured to the feed duct by one or more vanes which may be radial or helical and pref. the annular feed channel terminates in the region of max. dia. of spinning cup. The spun yarn may be withdrawn through the bottom of the spinning cup or through a bore in the centre-body. A more uniform distribution of fibres on the fibre collecting surface of the spinning cup is achieved thereby providing a better quality yarn.
