Definitions
- a drafting system for a spinning machine for stretching a fiber structure, comprising at least a first pair of rolls consisting of a top roll and a bottom roll, and a second pair of rolls consisting of an output top roll and an output bottom roll. ze, and with a downstream of the output roller pair fiber compression for compression of the stretched fiber structure.
- the fiber compression device has a pneumatic compression device with a fiber-bundling zone and with a suction tube looped around and sucked by a sieve element.
- FIG. 1 shows a schematic representation of a longitudinal section of a spinning machine according to the prior art, in particular a ring spinning machine. Shown are, by way of example, individual components of the spinning machine, namely a drafting system 2 and a spinning device 10.
- the drafting system 2 consists of three roller pairs, an input roller pair 3, a pair of apron rollers 4 and a pair of output rollers 5. However, it is also conceivable in the drafting system two or four pairs of rolls.
- the output roller pair 5 is formed by an output top roller 6 and an output bottom roller 7.
- the two rollers of a pair of rollers 3, 4 and 5 are pressed against each other and form a nip at their point of contact, a first nip K1 passing through the apron roller.
