Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Bei der Papierfabrikation hat man die Erfahrung gemacht, daß jeder Entwässerungsfilz bei Naßpressen in kurzer Zeit verschmutzt und dadurch die Papierbahn stellenweise zerpreßt; -infolgedessen mußte die Papiermaschine abgestellt und der Filz ausgewechselt werden.In paper manufacture, experience has shown that every dewatering felt soiled in a short time in wet presses and thereby crushed the paper web in places; -As a result, the paper machine had to be switched off and the felt replaced will.

Diese Stillstände zu vermeiden und die Filze zu sparen, ist der Zweck der neuen Einrichtung. The purpose of the new facility is to avoid these downtimes and to save felt.

Zwischen dem Preßfilz α und der unteren Preßwalze c ist nach Fig. ι ein starker durchlässiger, endloser Unterlagsfilz d unter Benutzung von Führungswalzen durchgeführt, welcher das Wasser aus dem Preßfilz a an der Preßstelle aufnimmt, so daß der Preßfilz a stets trocken und durchlässig bleibt und somit Wasser aus der Papierbahn gut aufnehmen kann. Α between the press felt and the lower press roll c in FIG. Ι a strong permeable, endless Unterlagsfilz d conducted by use of guide rollers, wherein the water from the press felt a receives at the nip so that the press felt a dry at all times and permeable remains and thus can absorb water from the paper web well.

Dadurch kann die Papierbahn stärker aus- ao gepreßt und Filze erspart werden.As a result, the paper web can be pressed out more and felts can be saved.

Nach Fig. 2 umspannt der Filz d zum Teil die Preßwalze c; der Filz d dient in diesem Falle als Ersatz für den bekannten Filz- oder Gummiüberzug der unteren Preßwalze.According to FIG. 2, the felt d partially spans the press roll c; the felt d serves in this case as a replacement for the known felt or rubber cover of the lower press roll.
