Description

technical field [0001] The present invention relates to a new type of compact unit in the forming section of a paper machine, more precisely to a self-supporting pre-assembled compact unit with an integrated save-all tray. On this unit are mounted rolls supporting the outer forming wire and / or the inner forming wire. Background technique [0002] A forming section in a conventional paper machine with, for example, a C-former and a crescent former typically comprises two rings of industrial clothing running around a plurality of guide rolls and guide rolls, to which the papermaking stock is conveyed via a headbox. between the clothings to form the web therebetween. One ring of the clothing forms the outer wire ring, while the second ring forms the inner wire ring. The paper stock is partially dewatered in the forming section and the water is drained through the wire and collected by a recovery trough located below the wire. The gutter is usually made of sheet metal and ext...
