Unit in a forming section of a papermaking machine

Abstract

The invention discloses a pre-assembled self-supporting unit (1) for a twine wire forming section. The unit comprises an integrated save-all tray (25) and other integrated elements such as cross walkway (17) , piping beam (10) , connecting arms (8) . The rolls (2) for supporting at least one forming clothing loop (4) and the other elements are mounted onto this separate unit instead of being mounted onto the same machine frame. The unit provides a diminished foot print for the forming section, and it is dimensioned to fit in a standard transport container.

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...
