Claims (21)

1. A process for the conditioning of fibres or other particles prior to their suspension in a liquid bath for the manufacture of a continuous web of non-woven textile,. or paper, wherein, during a first period of time, the fibres or particles are finely dispersed in a gaseous fluid, during a socond period of time the thus dispersed fibres or particles are deposited in the form of a sheet on a movable support which enters a liquid bath for the wetting of the sheet of fibres or particles carried with the support, and during a third period of time the wet sheet of fibres or particles Is detached from the support and the thus wetted fibres or particles are suspended in a liquid bath for the manufacture of a web.
2. A process according to Claim 1, wherein the fibres OF particles are dispersed mechanically and directly deposited on the movable support,
3. A process according to Claim 1, wherein the fibres or particles are dispersed mechanically and taken up by a stream of gas to bo transported to the movable support.
4. A process according to Claim 5, wherein the fibres or particles, along their path of travel in the gas stream, are submitted to auxiliary treatments and/or to the addition of additives.
5. process acoording to Claim 1, wherein the wetting of the fibres or particles is effected by passing a stream of liquid under pressure through the sheet of fibres or particles oarried by the support, during the passage of the latter through the wetting bath.
6. Δ process according to Claim 1, wherein the fibres or particleo, after being detached from the support, are stored in the form of a highly concentrated suspension, adapted for later dilution for the manufacture of a *eb.
7. « A process according to Claim 1, wherein the fibres or particles are detached from the movable support by a stream of liquid, traversing the permeable support from the interior outwardly, the fibres or particles together with the liquid used for detaching thorn, forming the suspension adapted for the manufacture of a web.
8. A process according to Claim 7, wherein the fibres or particles are maintained on the support during a first part of ita passage through the bath, and are detached from the support and extracted, during a second part of its passage through the bath, by means of a, liquid stream,
9. A process according to any one of Claims 1 to 5, wherein the liquid in the wetting bath contains in suspension other fibres or particles capable of adding to the sheet of fibres or particles already formed on the movable support, during the passage of said support through the, wetting bath.

13. Apparatus according to Claim 12, wherein the connecting conduit passes through a chamber for dispersing the mixture and for the pretreatment of the fibres in the gaseous medium
14. Apparatus according to Claim 11, wherein the movable support passes underneath the exit of the hopper, which latter comprises at its base a device for the mechanical dispersion of the fibres and for their deposition on the movable support.
15. ·: Apparatus according to Claims 11, 12 or 13, wherein the movable support consists of a perforated drum.
16. Apparatus according to Claims 11, 12 or 13, wherein the, movable support consists of an endless sheet passing over a perforated drum hich penetrates the bath.
17. » Apparatus according to Claims 11, 12 or 13, wherein the movable support consists of two endless sheets which advance at equal velocities and are pressed to each other over a part of their paths during ifhich they pass through the wotting bath, the fibres being deposited on at least one of th sheets, upstream of said part of the path, and held between the two sheets during their passage through the wetting bath.
18. Apparatus according to Claim 11, wherein the means for depositing the fibres on the support consists of at least one suction box, over which the support-sheet passes, the fibres being deposited on the permeable sheet by suction of a gaseous fluid inwards.
19. Apparatus according to Claim 16, which comprises means for evacuating the wetting liquid which penetrates through /the perforated drum and for maintaining the liquid inside the drum at a lower level than on its outside.
20. Apparatus according to Claim 11, wherein the means for detaching the sheet of fibres from the movable support consists of a liquid stream forced through the permeable sheet fro the inside outwardly so as to entrain the fibres and form the suspension -adapted to being fed into the web-manufacturing machine,
21. Apparatus according to Claim 11, which comprises a single vat divided into two parts by the movable support, an upstream part eorving as a wetting chamber, and a downstream part opening into tho suspension- eed conduit, the wetting and suspending liquid passing through the endless sheet, successively, from the wetting chamber into the interior of the endless sheet and from the interior towards the sus ension-feed conduit. 22· Apparatus for the conditioning of fibres according to any one of Claims 11 to 20» substantially as herein described with reference to the attached drawings.
