Abstract

Die Erfindung bezieht sich auf eine Vorrichtung zur Streckung von Materialbahnen (2) quer zu ihrer Laufrichtung, bestehend aus mindestens einer sich quer zur Laufrichtung der Materialbahn erstreckenden drehbaren Breitstreckwalze.The invention relates to a device for stretching webs of material (2) transversely to its running direction, comprising at least one rotatable spreader roll extending transversely to the running direction of the web of material.

Um zu erreichen, dass eine solche Vorrichtung sehr leichtgängig läuft, die zu streckende Materialbahn (2)kaum belastet und dementsprechend auch für eine Querstreckung dünner Kunststoff- und Metallfolien geeignet ist, optimal auf die technologischen Vorgaben eingestellt werden kann und ein so geringes Trägheitsmoment besitzt, dass sie auftretenden Geschwindigkeitsänderungen der Materialbahn (2) leicht folgen kann, ist die Breitstreckwalze aus mindestens zwei axial zueinander ausgerichteten Rundrohren (3a, 3b) gebildet, die sich über Gelenklager (6,7) auf Stegen (9) abstützen, die ihrerseits verstellbar auf einem Grundgestell (10) montiert sind.

Figure imgaf001
In order to achieve that such a device runs very smoothly, the web of material to be stretched (2) hardly loaded and therefore suitable for a transverse extension of thin plastic and metal foils, can be optimally adjusted to the technological specifications and has such a low moment of inertia, that it can easily follow occurring changes in speed of the material web (2), the spreader roller from at least two axially aligned circular tubes (3a, 3b) is formed, which are supported by joint bearings (6,7) on webs (9), which in turn adjustable a base frame (10) are mounted.
