Description

Stoffauflauf für Papier-, Karton- und Pappeninaschinen Die Erfindung bezieht sich auf einen Stoffauflauf für Papier-, Karton- und Pappeismaschinen und bezweckt eine bessere Verfilzung der Fasern.Headbox for paper, board and cardboard machines The invention refers to a headbox for paper, board and cardboard machines and aims to improve the felting of the fibers.

Stoffaufläufe, die den Zweck verfolgen, die Austrittsgeschwindigkeit des auf das Sieb auflaufenden Stoffes gleich oder annähernd gleich der Siebgeschwindigkeit zu machen, sind bekannt, geben aber den zwischen ihren Lippen austretenden Stoffasern vorzugsweise eine parallele, längsgerichtete Lage, die die Querfestigkeit der Papierbahn beeinträchtigt. Versuche, die Querfestigkeit durch Ablenkungsschaufeln an Stoffaufläufen zu verbessern, sind bekannt geworden bei Staulatten. Sie besitzen den Nachteil, daß die festen Stege, die die Ablenkungsschaufeln tragen, bis unmittelbar auf das Sieb herunterreichen, und daß zwischen diesen Stegen jeweils nur voneinander getrennte Austrittsöffnungen für den Stoff verbleiben, die in ihrer Gesamtheit weniger als die Hälfte der Siebbreite zum Austritt für den Stoff freigeben. Gegenstand der Erfindung ist, diese Mängel durch eine Vorrichtung abzustellen, die es gestattet, den Stoffstrom in voller Breite so auf das Sieb zu bringen, daß den Fasern beim Auflauf auf das Sieb eine schräg zum Sieblauf gerichtete Bewegung verliehen wird. In der Zeichnung ist in Aufriß, Grundriß und Seitenriß ein Ausführungsbeispiel der Erfindung schematisch dargestellt.Headboxes that have the purpose of the exit speed of the substance running onto the sieve is equal to or approximately the same as the sieving speed to make, are known, but give the fabric fibers emerging between their lips preferably a parallel, longitudinally oriented layer that increases the transverse strength of the paper web impaired. Attempts to increase the transverse strength by using deflector vanes on headboxes to improve, have become known in the case of stowage laths. They have the disadvantage that the solid webs that carry the deflection vanes, except for the Reach down sieve, and that between these webs only separate from each other Outlet openings for the substance remain, which in their entirety are less than release half of the wire width for the material to exit. Subject of the invention is to remedy these deficiencies by a device that allows the material flow in full width on the sieve in such a way that the fibers run onto the Sieve a movement directed obliquely to the sieve path is imparted. In the drawing Figure 3 is schematic in elevation, plan and side elevation of one embodiment of the invention shown.

In die obere und untere Lippe A 1 und A 2 der Auslaufschnauze eines Stoffauflaufes sind Rillen B1, B2 eingearbeitet, die schräg zu dem durch den Pfeil angezeigten Sieblauf gerichtet sind und dem auflaufenden Stoff eine schräg zum Sieblauf gerichtete Bewegung erteilen, wodurch vermieden wird, daß sich die Fasern vorwiegend in der Richtung des Sieblaufes einstellen.In the upper and lower lip A 1 and A 2 of the outlet spout one Grooves B1, B2 are incorporated into the headbox, which are inclined to the one indicated by the arrow The screen run indicated are directed and the accumulating material is inclined to the screen run give directional movement, thereby avoiding that the fibers predominate set in the direction of the sieve travel.

Die Vorrichtung ermöglicht eine gute Verfilzung selbst bei großen Siebbreiten und hohen Arbeitsgeschwindigkeiten.The device enables good matting even with large ones Screen widths and high working speeds.
