The invention provides an apparatus for forming a panel comprising a mesh support (10) and a transfer plate ~ (20) comprising at least one surface (30) comprising a plurality of pores having an average pore diameter of about 1200 microns or less. The invention further provides a method comprising (i) forming an aqueous composition comprising a fiber material, (ii) depositing the composition onto a movable mesh support (10) to form an entangled fiber material containing water; (iii) removing at least a portion of the water from the entangled fiber material, and (iv) transferring the entangled fiber material from the movable mesh support (10) by passing it over a transfer plate (20), wherein the transfer plate (20) comprises at least one surface ' (30) comprising a plurality of pores having an average pore diameter of about 1200 microns or less.
L'invention concerne un appareil pour la formation d'un panneau comprenant un support de maille (10) et une plaque de transfert (20) comprenant au moins une surface (30) comprenant une pluralité de pores ayant un diamètre moyen de pore d'environ 1 200 microns ou moins. L'invention concerne en outre un procédé comprenant (i) la formation d'une composition aqueuse comprenant un matériau fibreux, (ii) le dépôt de la composition sur un support de maille mobile (10) pour former un matériau fibreux enchevêtré contenant de l'eau; (iii) l'élimination d'au moins une partie de l'eau du matériau fibreux enchevêtré, et (iv) le transfert du matériau fibreux enchevêtré du support de maille mobile (10) en le passant sur une plaque de transfert (20), la plaque de transfert (20) comprenant au moins une surface (30) comprenant une pluralité de pores ayant un diamètre moyen de pore d'environ 1 200 microns ou moins.
