Abstract
In an apparatus for consolidating a conveyable fibre web, for example of cotton, synthetic fibers 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.
Claims39
An apparatus for consolidating a conveyable fibre web in a carding machine, comprising:
- a web funnel for receiving a web of fibre material;
- take-off rollers for taking-off fibre material from the web funnel;
- a consolidating device downstream of the take-off rollers and the web funnel, wherein the consolidating device is in the form of a drawing mechanism comprising at least two roller pairs arranged one behind the other, each pair of rollers comprising an upper roller and a lower roller biased against one another, and wherein there is at least some control of the speed of rotation of the rollers;
- and
- a web-guiding device arranged between the take-off rollers and the drawing mechanism, the web-guiding device comprising two endlessly revolving conveyor belts co-operating with one another.
An apparatus for consolidating a conveyable fibre web, comprising:
- a web funnel together with take-off rollers provided at the exit from a flat card or a roller card, wherein the outlet region of the web funnel has a substantially rectangular cross-section,
- a web-guiding device arranged downstream of the web funnel, the web-guiding device comprising two endlessly revolving conveyor belts co-operating with one another, and
- an endlessly revolving consolidating device provided downstream of the web funnel and the web-guiding device, wherein the consolidating device comprises at least two roller pairs, between which the fibre web passes, the at least two roller pairs arranged one behind the other, each of the at least two roller pairs including an upper roller and a lower roller biased by a force against one another, and wherein there is at least some control of the speed of rotation of the rollers.
