Method for producing a fibrous product comprising: passing a texturized yarn (10) through a first passage (12) having a first outlet (14); projecting the texturized yarn (10) from the first outlet (14), inside a chamber (20), so as to fill the chamber (20) with the texturized yarn (10), thereby form
Method for producing a fibrous product comprising: passing a texturized yarn (10) through a first passage (12) having a first outlet (14); projecting the texturized yarn (10) from the first outlet (14), inside a chamber (20), so as to fill the chamber (20) with the texturized yarn (10), thereby forming a first segment (31) of the fibrous product; moving the first segment (31) away from the first outlet (14); and forming a second segment (32) of the fibrous product in place of the first segment (31) and contiguously to the first segment (31), as many segments as necessary being contiguously formed by repeating the above steps. Apparatus for implementing the method.

1. An apparatus for producing a fibrous product between a first surface and a second surface, the apparatus comprising: means for texturizing at least one yarn comprising a plurality of glass fibers into a texturized yarn;a first passage having a first outlet;a first chamber including the first surface and the second surface;a shaft extending through the first chamber, wherein a surface of the shaft forms at least part of the second surface;means for projecting the texturized yarn into the first passage, such that the texturized yarn passes through the first outlet and into the first chamber;means for applying a binder to the texturized yarn after the texturized yarn exits the first outlet and before the texturized yarn enters the first chamber; andmeans for conveying a first segment of the fibrous product, formed when the texturized yarn with the binder applied thereto fills the first chamber between the first surface and the second surface, away from the first outlet, along a first axis, thereby allowing a second segment to be formed in place of the first segment and contiguously to the first segment. 2. An apparatus for producing a fibrous product between a first surface and a second surface, the apparatus comprising: a nozzle for transforming at least one yarn comprising a plurality of glass fibers into a texturized yarn;a first passage having a first outlet;a first chamber including the first surface and the second surface;a shaft extending through the first chamber;a binder injector; anda conveying system comprising a moving band;wherein the nozzle is interfaced with a source of compressed air for projecting the texturized yarn from the nozzle into the first passage, such that the texturized yarn passes through the first outlet and into the first chamber;wherein the binder injector is operable to apply a binder to the texturized yarn after the texturized yarn exits the first outlet and before the texturized yarn enters the first chamber;wherein the texturized yarn with the binder applied thereto fills the first chamber between the first surface and the second surface so as to form a first segment of the fibrous product;wherein a surface of the moving band forms at least part of the first surface;wherein a surface of the shaft forms at least part of the second surface; andwherein the conveying system is operable to move the first segment away from the first outlet, along a first axis, thereby allowing a second segment to be formed in place of the first segment and contiguously to the first segment. 3. The apparatus of claim 2, wherein the first surface extends substantially parallel to the first axis. 4. The apparatus of claim 2, wherein the first chamber has a constant cross-section. 5. The apparatus of claim 2, wherein the first outlet rotates around the first axis, with the texturized yarn passing through the rotating first outlet. 6. The apparatus of claim 5, wherein the first outlet continuously rotates 360 degrees around the first axis. 7. The apparatus of claim 5, wherein the first outlet rotates around the first axis at a rate between 40 rev/min to 600 rev/min. 8. The apparatus of claim 2, further comprising a folding shoe through which the moving band passes, the folding shoe being configured to wrap the moving band around the first axis. 9. The apparatus of claim 2, further comprising a suction device for applying suction through the moving band. 10. The apparatus of claim 2, further comprising a curing unit for curing the binder on the segments. 11. The apparatus of claim 2, wherein the second surface extends substantially parallel to the first axis. 12. The apparatus of claim 2, wherein the first passage is formed within the shaft. 13. The apparatus of claim 2, wherein the shaft rotates within the first chamber. 14. The apparatus of claim 2, wherein the texturized yarn is projected from the nozzle at a rate between 50 m/min to 600 m/min. 15. The apparatus of claim 2, wherein the moving band travels at a speed between 1 m/min to 50 m/min. 16. An apparatus for producing a fibrous product between a first surface and a second surface, the apparatus comprising: a nozzle for transforming at least one yarn comprising a plurality of glass fibers into a texturized yarn;a passage having an outlet;a chamber including the first surface and the second surface;a first shaft extending through the chamber;a second shaft extending through the chamber;a conveying system comprising a moving band;wherein the nozzle is interfaced with a source of compressed air for projecting the texturized yarn from the nozzle into the passage, such that the texturized yarn passes through the outlet and into the chamber;wherein the texturized yarn fills the chamber between the first surface and the second surface so as to form a first segment of the fibrous product;wherein a surface of the moving band forms at least part of the first surface;wherein a surface of the first shaft forms at least part of the second surface;wherein a surface of the second shaft forms at least part of the second surface; andwherein the conveying system is operable to move the first segment away from the outlet, along a first axis, thereby allowing a second segment to be formed in place of the first segment and contiguously to the first segment. 17. The apparatus of claim 16, wherein a belt extends around the first shaft and the second shaft within the chamber, the belt forming at least part of the second surface. 18. The apparatus of claim 16, wherein the chamber has an asymmetric cross-section. 19. The apparatus of claim 16, further comprising a binder injector, wherein the binder injector is operable to apply a binder to the texturized yarn after the texturized yarn exits the outlet and before the texturized yarn enters the chamber. 20. The apparatus of claim 19, further comprising a curing unit for curing the binder on the segments.
