Paper converting plant

A paper converting plant for converting paper webs, comprising:

• a rewinder that is adapted to produce paper logs and has an inlet for feeding a paper web, a winding station where the paper logs are formed and an exit station for unloading the finished logs, wherein the rewinder is provided with a plurality of walls delimiting a chamber inside which the paper logs are formed, and an air suction channel disposed and acting at a lower part of said chamber, said air suction channel being adapted to exert a suction that causes the formation of an air flow directed from the top to the bottom inside the chamber, wherein said chamber is subdivided into two semi-chambers both communicating with the air suction channel such that a vertical air flow directed downwards is generated in each of them, said chamber being provided with regulating means for regulating said vertical air flows to provide vertically oriented identical air flow rates in the semi-chambers.
