support body for an apparatus having an extended nip, support body assembly for an apparatus having an extended nip, apparatus for treating a fiber network, method of forming an extended nip in an apparatus for treating an a fiber net, a method of controlling the load in an extended nip in an apparatus for treating a fiber net and using a support body. It is a support body (7) for an apparatus having an extended nip (n) formed between the support body and a back pressure member, which has a work surface (13), is elastically deformable, and comprises a plurality of pressurized pressure chambers (94, 96, 98) for controlled expansion towards the work surface in order to carry the nip (n) according to the invention, the support body comprises a plurality of reinforcement profiles (100, 106, 108) arranged in at least one chamber of the pressure chambers, wherein the interiors of the profiles are in fluid communication with each other through holes (102), with a profile wall facing said one. work surface includes holes (104, 107, 109) for fluid communication between the interior of the profile and the chamber in which said profile is located, and said profiles provide an internal wall support defining at least one chamber. Ara. The invention also relates to a support body assembly for an apparatus having an extended nip comprising said support body and a retainer (8) for the support body forming an outer support for all sides of the support body having said chambers, except the work surface side. The invention also relates to an apparatus for treating a fiber net comprising said support body assembly. Also provided are methods of forming an extended nip and controlling the load in an extended nip in said apparatus.
