An apparatus for producing, in bulk, long tailed neps, the apparatus including a housing supporting a main rotor the periphery of which has a plurality of teeth and beaters which co-operate with teeth on a set of feed rollers mounted in the housing alongside the periphery of the main rotor, the housing having an intake chute and a closeable discharge door, the arrangement being such that, in use, a synthetic or material fibrous material fed to the intake chute, while the discharge door is closed, is fed into the housing by the feed rollers, the fibrous material being removed by the beaters and teeth of the rotor from the feed rollers, the fibrous material being spun in the housing and the interaction between the teeth and the beaters of the main rotor and the teeth of the feed rollers causing the fibrous material to be entangled and felted to form a plurality of long tailed neps which are discharged from the housing when the discharge door is opened.
An apparatus for producing, in bulk, long tailed neps, the apparatus including a housing supporting a main rotor which has on its periphery a plurality of teeth and beaters which cooperate with teeth positioned on a set of feed rollers mounted on the inner periphery of the housing, the housing having an intake chute and a closeable discharge door, the arrangement being such that, in use, a synthetic or material fibrous material fed to the intake chute, while the discharge door is closed, is fed into the housing by the feed rollers, the fibrous material being removed by the beaters and teeth of the rotor from the feed rollers, the fibrous material being spun in the housing and the interaction between the teeth and the beaters of the main rotor and the teeth of the feed rollers causing the fibrous material to be entangled and felted to form a plurality of long tailed neps which are discharged from the housing when the discharge door is opened.
