Abstract

Ein als Gapformer betriebener Doppelsiebformer (3) mit einem Innensieb (4) und einem Außensieb (5) enthält im initialen Formierbereich eine Formierwalze (8) mit mindestens 800 mm Durchmesser. Nach dem Ablaufen der Siebe von der Formierwalze gelangen sie in eine mit Formierleisten (10, 11) versehenen Bereich, in dem die Siebe relativ steil abwärts laufen. Die so gebildete obere Lage (6) wird auf eine untere Lage (7) abgelegt, die auf dem Primärlangsieb (2) bereits gebildet wurde.

Figure 00000001
A twin wire former (3) operated as a gap former with an inner wire (4) and an outer wire (5) contains a forming roller (8) with a diameter of at least 800 mm in the initial forming area. After the sieves have run off the forming roller, they reach an area provided with forming strips (10, 11), in which the sieves run relatively steeply downwards. The upper layer (6) thus formed is placed on a lower layer (7) which has already been formed on the primary longitudinal screen (2).
