A method and mechanism for manufacturing long-tailed neps useful as a fill or effect material the method including feeding a synthetic or natural fibrous material to a woollen opening mechanism with its outlet closed, running the opening mechanism for a predetermined period, opening the outlet of the opening mechanism so that a rotating fan doffer roller of the opening mechanism throws therefrom a plurality of modified fibre neps, each of which has a nep-shaped region from the fibres of which extends a tail (long-tailed neps). The fibrous material can be scoured wool, a synthetic fibrous material or woollen fibres in an unclean state with vegetable matter and other contaminants entrained therewith. The mechanism includes a housing having a closable inlet and a closable outlet, the housing forming a chamber in which a rotating roller member is mounted, the rotating roller member having on its periphery a plurality of teeth which co-operate with teeth located in the chamber, the mechanism operating on the fibrous material fed through the inlet to spin it in the closed chamber for a predetermined period and by the interaction of the teeth, form it into a plurality of long-tailed neps.
In an apparatus for manufacturing long-tailed neps useful as a fill or effect material, said apparatus including
A method of converting fibrous material into long-tailed neps useful as a fill or effect material using a woollen opening mechanism which includes a housing which defines a treatment chamber therein and provides having an inlet opening and an outlet opening, a drum having outwardly-extending teeth positioned in said treatment chamber, cooperating teeth positioned in said treatment chamber adjacent the outwardly-extending teeth of said drum, and a fan doffer roller positioned in said treatment chamber between said drum and said outlet opening, said method comprising the steps of
