Abstract
In an apparatus for consolidating a conveyable fibre web, for example of cotton, synthetic fibres or the like, there is provided, at the exit from a flat card, roller card or the like, a web funnel together with take-off rollers, the outlet region of the web funnel has a substantially rectangular cross-section, and an endlessly revolving consolidating device, for example comprising two rollers, is provided downstream of the web funnel. In order to improve the apparatus for consolidation, the consolidating device comprises at least two roller pairs arranged one behind the other, which are biased by a force and the speed of rotation of which can be controlled.
Claims45
An apparatus for consolidating a conveyable fibre web in a carding machine, comprising:
- a web funnel for receiving a web of fibre material;
- a consolidating device downstream of the web funnel wherein:
- the consolidating device comprises at least two roller pairs arranged one behind the other, each pair of rollers being biased;
- and
- there is at least some control of the speed of rotation of the rollers.
A consolidating device for consolidating a conveyable fibre web, comprising at least two roller pairs arranged one behind the other, at least one roller of each pair being biased, and wherein there is at least some control of the speed of rotation of the rollers, the consolidating device being arranged to receive a web of carded fibre material.
An apparatus for consolidating a conveyable fibre web, wherein a web funnel together with take-off rollers is provided at the exit from a flat card, roller card or the like, the outlet region of the web funnel has a substantially rectangular cross-section, and an endlessly revolving consolidating device comprising two rollers, between which the fibre web passes, is provided downstream of the web funnel, wherein the consolidating device comprises at least two roller pairs arranged one behind the other, which are biased by a force and there is at least some control of the speed of rotation of the rollers.
