Abstract

Es wird eine Vorrichtung zum Führen einer Bahn von einer ersten Position zu einer zweiten Position, insbesondere von einer Abwickelstation zu einem Wickelabschnitt einer Rollenwickeleinrichtung, angegeben mit einer Hilfseinrichtung (21), die die Bahn an der ersten Position in voller Breite erfaßt.A device is provided for guiding a web from a first position to a second position, in particular from an unwinding station to a winding section of a reel-winding device, having an auxiliary device (21) which engages the web at the first full-width position.

Man möchte auf einfache Weise die Bahn im Bereich ihres Anfangs in voller Breite erfassen können.One would like to be able to easily grasp the web at its beginning in full width.

Hierzu ist vorgesehen, daß die Hilfseinrichtung (21) ein erstes Halteelement (31), das sich quer zur Längserstreckung der Bahn (9) und mindestens über die Breite der Bahn (9) erstreckt, und ein zweites Halteelement (35) aufweist, das gegenüber dem ersten Halteelement (31) in eine Öffnungsposition, in der zwischen den beiden Halteelementen (31, 35) ein Raum (48) zur Aufnahme eines Bahnanfangs (30) gebildet ist, und in eine Schließposition verlagerbar ist, in der die beiden Halteelemente (31, 35) unter Zwischenlage des Bahnanfangs (30) aneinander anliegen, wobei eines der Halteelemente (31, 35) eine Magnetanordnung (38) aufweist, die in der Schließposition das andere Halteelement (35, 31) festhält.

For this purpose, it is provided that the auxiliary device (21) has a first holding element (31) which extends transversely to the longitudinal extent of the web (9) and at least over the width of the web (9), and a second holding element (35), opposite the first holding element (31) in an opening position, in which between the two holding elements (31, 35) a space (48) for receiving a web start (30) is formed, and in a closed position is displaceable, in which the two holding elements (31 , 35) with the interposition of the web start (30) abut each other, wherein one of the holding elements (31, 35) has a magnet arrangement (38) which holds the other holding element (35, 31) in the closed position.
