  • the fibres are picked from bales by a picker, so as to obtain tufts transported by currents of air.
  • the fibre in tufts is subsequently treated in a device for removing impurities, such as stones or non- ferrous materials mixed with the tufts, before passing to an axial opener, where the tufts undergo a first opening of the fibre and a first separation from the impurities.

  • the opener 8 comprises cleaning means suitable to cooperate with a respective roller 16, 22 to separate impurities from the fibres being processed.
  • the cleaning means comprise a grid 50 which extends in an arch around its respective cleaning roller 16, 22 along said rotation axis Y, Z, in the area below this in the direction of the force of gravity.
  • the grids 50 are positioned under the rollers 16, 22, so that by centrifugal force and reciprocal collision of the fibres, impurities such as husks are separated from the tufts being processed.
  • the grids 50 are adjustable, so as to enable adjustment according to the type and degree of dirt of the fibre to be processed.
  • the impurities separated from the fibre are removed from the opener by appropriate conveyance and transport devices of the accumulated impurities.
  • the fibre to be processed F in other words the fibre in tufts still considerably dirty and mixed with impurities, is transported, for example aspirated, towards the feed device 4, where the small impurities and dust are separated by collision
  • the fibre to be processed F is then sent to the input pipe 10 which contemporaneously feeds the two compartments 18, 24, separating the flow of fibre into two flows, each processed by an opener roller.
  • deviator means for example functioning with a jet of air.
  • the separation which is performed downline of the separator device, takes place in fact in a section in which the fibre is already evenly spread over the width of the feed pipe to the rollers and in which the speed of the flow is low, helped by the force of gravity.
  • this makes the separation less influenced by agents such as the high speed of the flow or different suction powers, which might otherwise cause one compartment to fill more or less than the other, as happens in T or Y separators positioned along the feed pipes to the machines.
  • each opener roller processes about half of the total fibres being treated on the processing line, advantageously minimising the quantity of fibre processed in the individual compartments and the differences in the degree of processing of the two flows of fibre, with excellent quality results of the processing performed and of the homogeneity of the tufts.
  • the tufts entangled on the pegs of the opening means tend to pass from one peg to another, progressively moving towards the exit, for example by air suction, undergoing a sort of unravelling which opens the tufts.
  • the tufts dragged in rotation collide against the grid 50, so as to cause the separation of further impurities such as husks.
  • the opener according to the present invention resolves the drawbacks of the known art inasmuch as it renders unnecessary the design of openers for large quantities of fibre difficult to construct and unacceptably large while also enabling high quality, uniformly processed fibre tufts to be obtained.
  • the opener according to the present invention makes it possible to reduce construction costs compared to constructing two independent fibre processing lines.
  • the opener according to the present invention makes it possible to concentrate in a single machine the salient treatments, high technological and important for the quality of the fibre, dividing the flow of fibre to achieve high quality, while the transport of the fibre between the various machines occurs for the entire flow of fibre in a single pipe.
