Abstract: The papermaking machine contains at least one water pervious dewatering wire or the like for forming a fiber web, particularly one layer of a multi-ply fiber web, and at least one headbox for infeeding a fiber stock suspension to be applied in the form of a free jet to the dewatering wire. Between the headbox and a section of the dewatering wire extending along the headbox there is arranged at least one deflecting device for separating and withdrawing a partial flow or stream of the fiber stock suspension. The deflecting device can be inserted into a marginal region of the free stock jet. Such an arrangement enables, for example, a continuous or infinitely variable adjustment of the format width of the fiber web to be produced. During use of the deflecting device, the partial flow or stream of the stock is deflected prior to the formation of the fiber web and is kept away from the following operational or working sections of the papermaking machine, in particular from a second fiber web or ply located thereat. If desired, the deflected partial stock flow can be returned to the fiber stock suspension supply or infeed system preceding or upstream of the headbox for re-use of the unmixed fiber stock material.

Abstract: The wet section of a twin wire papermaking machine is provided with an open forming roll at the lower wire and with the combination of a suction box at the lower wire and a vacuum suction box at the upper wire. Furthermore, by selecting the elevational position or level of the individual wire sections there can be obtained particularly advantageous conditions for the operation of the papermaking machine throughout a wide field of application, especially heavy types of paper at relatively low operating velocities of the papermaking machine. Gap-former and hybrid-former constructions of the papermaking machine are possible.

Abstract: A twin-wire papermaking machine contains a headbox for forming a first fiber ply which is essentially downwardly dewatered at a section of a first wire. At the end of this wire section, forwardly or upstream of the inbound or on-running location of a second wire there is arranged a second headbox for forming a second fiber ply which is essentially upwardly dewatered along a subsequently arranged common path of both wires. The common path advantageously extends over an essentially water impervious, convex domed contact surface of a slide shoe and/or a jacket surface of a guide cylinder or roll. During operation, the second fiber ply is deposited upon the already extensively dewatered first fiber ply and upon passage through the common path of both wires this second fiber ply is dewatered upwardly away from the first fiber ply. This enables separate dewatering of both fiber plies, and there is particularly avoided deflocculation of individual fibers, and thus, impairment of the fiber formation in the initially formed ply.
