Spinning device

The invention relates to a spinning device, in which at least one fibrous strip (2) is split into individual fibres (4), the individual fibres, in the form of an opened out fibrous veil, being placed on a mobile collecting surface (5) which is in the form of an air-permeable transporting strip (6). During the transport on the collecting surface, the fibrous veil (7) is compacted into a fibrous structure (8), transversally in relation to its direction of displacement. Said fibrous structure, now resembling a sliver, is transported through a clamping line and rotated by means of a swirl nozzle (11) to form a thread (12). The aim of the invention is to gently transfer the individual fibres from a combing cylinder (16), which unravels the fibrous structure, to the collecting surface (5). To this end, the outer side of the transport strip (6) surrounds a partial region of the circumference of the combing cylinder.

DRAWING DEVICE FOR CONTINUOUS RING SPINNING

Pressure roller for spinning machines

Drafting mechanism - has feed guide maintaining the roving under tension

The roving passes between co-operating guide surfaces pref. the surfaces of a pair of guide rolls, which exert a braking effect on the roving and maintain it under tension between the guide surfaces and the feed rollers of the drafting mechanism. Pref. the guide rolls and resiliently biassed together and are provided with brakes which oppose rotation caused by contact with the advancing roving. Alternatively the guide surfaces may be defined by a pair of aprons. The tension imparted to the roving reduces twist variation, and ensures correct fibre alignment as the roving is presented to the drafting mechanism.
