Abstract
An apparatus on a textile machine for cleaning fibre has a high-speed first roller conveying a fibre web, and second and third rollers. Second roller is arranged downstream of third roller and so co-operates with first roller, that fibre is detached, the fibre is transferred to nip, with third roller and is conveyed by third roller to nip with first roller where it is transferred back to the first roller. A separating knife is arranged downstream of the second roller. In order to improve the degree of cleaning between separating knife and the nip of first roller with second roller there is a separation opening of width about from 40 to 60 mm.
Claims18
An apparatus on a textile machine for cleaning fibre material, wherein the apparatus comprises:
- a first rotating roller arranged to convey a travelling fibre web;
- a second rotating roller co-operating with the first roller to form a first nip;
- a third roller co-operating with the second roller to form a second nip and with the first roller to form a third nip, the second roller being downstream of the third roller;
- a drive arrangement arranged to rotate at least one of the second and third rollers in the opposite direction to the direction of rotation of the first roller;
- the arrangement being such that fibre material is opened and detached at the first nip, and the detached fibre material is transferred to the second nip and is conveyed by the third roller to the third nip, where it is transferred back to the first roller;
- and
- the apparatus further comprising a separating element co-operating with the first roller and arranged downstream of the second roller, and a separation opening between the separating element and the nip between the first and second rollers, the separation opening having a width of about from 40 to 60 mm.
An apparatus on a flat card, roller card or the like for cleaning fibre material, comprising a high-speed first or main roller, which is adapted to support or convey a travelling fibre web, associated second and third rollers, which have respective nips with one another and with the first roller on rotation of the three rollers, and drive means for rotation of the rollers, which drive means are so arranged that the second roller is rotated in a direction of rotation that is the same as that of the first roller and opposite to that of the third roller, wherein the second roller is arranged downstream of the third roller and so co-operates with the first roller that a fibre mat is opened and detached, the fibre mat is transferred to the nip with the third roller and is conveyed by the third roller to the nip with the first roller, where it is transferred back to the first roller, a separating knife being arranged downstream—seen in the direction of rotation of the first or main roller—of the second roller, wherein between the edge of the separating knife and the nip of the first or main roller with the second roller there is a separation opening having a width of about from 40 to 60 mm.
