Abstract
The invention relates to a spinning device for the manufacture of a spun thread from a fiber bundle, surrounding a nozzle block (20) with one or more nozzles (21), which take effect on a fiber bundle which is conveyed at a suction drum (4) through the channels (14 and 15) against a spindle (32), and in this situation the rear fiber ends are taken up and rotated in the direction of rotation of the air flow in such a way that they rotate the front ends of the fibres which are already located in the yarn guide channel (45) to form a yarn (46). In this situation, the channel (14) features a longer middle conveying length (24.13) than the middle conveying length (24.14) of the channel (15).
Claims14
A method for the manufacture of a spun fibre from a fibre bundle the fibres of which are subjected to a rotating air flow and as a result are rotated in an intake mouth (35) of a yarn channel (45) of a spindle (32) to form a thread, whereby the fibres are predominantly divided into at least two fibre bundles, each of which is conveyed under predetermined processing features between a fibre delivery point (P, K, K.1) and the spindle intake mouth (35), characterised in that the processing features are capable of being adapted in such a way that an influence can in this way be exerted on the structure of the thread.
A device for the manufacture of a spun thread from a fibre bundle, in which the fibres are subjected to a rotating air flow in a nozzle block (20) with one or more nozzles (21), and as a result are rotated in an intake mouth (35) of a yam channel (45) of a spindle (32) to form a thread, whereby the fibres are predominantly conducted to the nozzle block through one fibre conveying channel (8) each to guiding the fibres of a separate fibre bundle in each case, each under predetermined device features between a fibre discharge point (P,K,K.1) and the spindle intake mouth (35), characterised in that the device features are capable of being adapted by corresponding measures in such a way that an influence can as a result be exerted on the structure of the fibre.
