Description
Langsiebpapier-, Karton- oder Pappenmaschine, bei der die Begrenzung der Stoffbahn durch zwei in der Breite verstellbare Begrenzungsstreifen und durch Wasserstrahlen erfolgt ,Die vorliegende Erfindung bezieht,sich auf eine Forrnatbegren.zung an Langsiebpapier-, Karton- oder Pappenmaschinen und hat eine besondere Art der Abdichtung der Begrenzungsleisten zum Gegenstand.Fourdrinier paper, board or cardboard machine where the limit the length of the fabric through two width-adjustable boundary strips and through The present invention relates to a format limitation on Fourdrinier paper, board or cardboard machines and has a special type of Sealing of the delimitation strips to the object.
Diese Formatbegrenzung wird .durch je ein in an sich; bekannter Weise feststehendes Lineal und einen auf dieses Lineal :gerichteten Wasiserstrahl auf jeder Seite des Siebes bewerkstelligt, ,doch wird bei .der vorliegenden Erfindung -der Wasserstrahl nicht von oben an das feststehende Lineal .gespritzt, sondern von unten durch ;das Sieb hindurch. Dadurch wird erreicht, daß :der Wasiser strahl auf die ganze Breite :der Begrenzungsleiste gerichtet werden kann, :die Begrenzungsleiste auf ihrer vollen Breite bestrichen wird, und daß zwischen Leiste und Stoff eine Ausbreitung des Wasserstrahles in Gestalt eines Wirbels auftritt, der den Stoff wirksam daran hindert, unter .der Leiste durch nach außen herauszutreten.This format limitation is .by one in itself; known way fixed ruler and a jet of washer directed at this ruler accomplished on each side of the screen, but in the present invention -The water jet is not sprayed onto the fixed ruler from above, but through from below; through the sieve. This means that: the Wasiser shines can be directed to the entire width of: the delimiting bar,: the delimiting bar is coated over its full width, and that between the strip and the fabric Propagation of the water jet occurs in the form of a vortex, which the substance effectively prevents it from stepping out from under the bar.
Die Ab.b. I und 2 zeigen schematisch eine solche Vorrichtung, Ab b. 3 und 4 in vergrößertem Maßstab die Wirbelbildung und Abidichtungdurch den von unten gegen die AUidichtungsleiste gerichteten Wasserstrahl.The fig. I and 2 schematically show such a device, Ab b. 3 and 4, on an enlarged scale, the vortex formation and sealing by the from below water jet directed against the sealing strip.
Das Sieb a läuft über die Registerwalzen b1, b2, b3 usw. Die Breite der Papierbahn c wird bestimmt durch :die Formatleisten dl, d2, die, um ihre Abnutzung zu vermeiden und das Sieb zu schonen, dieses nicht berühren. Die Spalte e1 und e2 sind durch einen Wasserwirbel ausgefüllt. Die unterhalb des Siebes befindlichen Spritzrohre g1 und g2 sind so gebohrt, daß die .austretenden Wasserstrahlen gegen den unteren Rand der J3egrenzungsleisten dl, d2 gerichtet sind,The sieve a runs over the register rollers b1, b2, b3, etc. The width the paper web c is determined by: the format strips dl, d2, the, to their wear to avoid and to protect the sieve, do not touch it. The column e1 and e2 are filled with a water vortex. The ones below the sieve Spray pipes g1 and g2 are drilled so that the .ausende water jets against the lower edge of the limit strips dl, d2 are directed,
