Abstract

Die Erfindung betrifft eine Vorrichtung zum Führen bzw. Überführen einer Papier-, Karton- oder anderen Faserstoffbahn von einer bahnabgebenden Bahnführungsfläche (3) einer ersten Bearbeitungs- bzw. Herstellungsstation zur nächsten Station (4) bzw. zu einer bahnaufnehmenden Bahnführungsfläche (5) entlang eines Bahnlaufweges (L) innerhalb einer Maschine (6) zur Herstellung und/oder Veredelung der Faserstoffbahn (2). Die Vorrichtung weist wenigstens eine Randdüse (7) auf zum Ablösen der Bahn bzw. eines von der Bahn abgetrennten Einfädelstreifens von der bahnabgebenden Führungsfläche (3) mittels eines aus der wenigstens einen Randdüse (7) ausgestoßenen Luftstrahles. Die Vorrichtung weist ferner einen Bandförderer (10) auf zum Ansaugen und Weitertransportieren der Bahn bzw. des Einfädelstreifens (2b) zur nächsten bahnaufnehmenden Bahnführungsfläche (5). Der Bandförderer (10) weist einen Unterdruckkasten (12) sowie ein luftdurchlässiges endloses Förderband (13), welches über eine stromaufwärtige Walze (14) und eine stromabwärtig angeordnete Walze (15) geführt ist, auf. Die stromaufwärtige Walze (14) ist als Saugwalze ausgebildet und bildet ein stromaufwärtiges Ende (16) des Bandförderers (10).The invention relates to a device for guiding or transferring a paper, board or other fibrous web from a web-emitting web guide surface (3) of a first processing or manufacturing station to the next station (4) or to a web-receiving web guide surface (5) along a Web path (L) within a machine (6) for producing and / or finishing the fibrous web (2). The device has at least one edge nozzle (7) for detaching the web or a threading strip separated from the web from the web-dispensing guide surface (3) by means of an air jet ejected from the at least one edge nozzle (7). The apparatus further comprises a belt conveyor (10) for sucking and further transporting the web or the threading strip (2b) to the next web-receiving web guide surface (5). The belt conveyor (10) has a vacuum box (12) and an air-permeable endless conveyor belt (13), which is guided over an upstream roller (14) and a downstream arranged roller (15) on. The upstream roller (14) is formed as a suction roller and forms an upstream end (16) of the belt conveyor (10).

Erfindungsgemäß ist vorgesehen, dass die stromaufwärtige Walze (14) einen geringeren Durchmesser als die stromabwärtige Walze (15) aufweist, wodurch der Bandförderer (10) nahe an die bahnabgebende Bahnführungsfläche (3) heranreicht, und dass dem stromaufwärtigen Ende (16) ein in Querrichtung wirkendes Trennelement (11) zur Abtrennung der Bahn bzw. des Einfädelstreifens (2) und Bildung eines neuen Bahnanfanges zugeordnet ist.

Figure imgaf001
According to the invention, it is provided that the upstream roller (14) has a smaller diameter than the downstream roller (15), whereby the belt conveyor (10) comes close to the web-delivering web guide surface (3), and that the upstream end (16) in a transverse direction acting separating element (11) for separating the web or the Einfädelstreifens (2) and forming a new web start is assigned.
