Die Erfindung betrifft einen rohrförmigen Wickelkern aus einer gewickelten Bahn aus Pappe oder dergleichen.The invention relates to a tubular winding core made of a wound web of cardboard or the like.
Derartige Wickelkerne sind aus der Praxis bekannt. Sie besitzen einen sehr einfachen Aufbau, denn sie sind aus einer Pappbahn oder dergleichen gewickelt» wobei zur Verbesserung der Stabilität die einzelnen Lagen miteinander verbunden sind. Aufgrund dieses Aufbaus endet die Pappbahn mit einer Endkante auf der Oberfläche des Winkelkerns. Werden nun empfindliche Material bahnen, z. B. aus Samt oder Kunststoffolie, auf den Wickelkern aufgewickelt, dann bildet sich die Endkante der Pappbahn und/oder die Endkante der Materialbahn auf den inneren Lagen dieser aufgewickelten Materialbahn ab. Da diese Abbildung Druckstellen hinterlaßt, die meistens nur schwer oder garnicht zu beseitigenSuch winding cores are known from practice. They have a very simple structure, because they are wound from a cardboard web or the like, whereby the individual layers are connected to one another to improve stability. Due to this structure, the cardboard web ends with an end edge on the surface of the angle core. If sensitive material webs, e.g. made of velvet or plastic film, are wound onto the winding core, then the end edge of the cardboard web and/or the end edge of the material web is formed on the inner layers of this wound material web. Since this formation leaves pressure marks that are usually difficult or impossible to remove, ist, müssen die inneren Lagert der aufgewickelten Material·is, the inner bearings of the wound material·

eingangs beschriebenen Gattung so zu Verbessern, daß die inneren Lagen der äUfgewiekel ten Materiälbähn frei von Druckstellen bleiben*To improve the type described above so that the inner layers of the wound material strips remain free of pressure points*
Diese Aufgäbe wird dadurch gelöst, daß auf der äußeren Oberfläche des Wickelkerns durchgehend ein Polster angeordnet ist. Dieses Polster deckt die Endkärite der äußeren Papplage ab und bildet ein nachgiebiges Widerlager der aufgewickeiten Material bahn * Eine bevorzugte Ausführung der Erfindung ist dadurch gekennzeichnet» daß das Polster aus auf die Oberfläche aufgef1ockten Fasern besteht. Diese Fasern genügen bereits, um die gewünschte Polsterwirkung zu erzeugen.This task is solved by a continuous padding on the outer surface of the winding core. This padding covers the end edge of the outer cardboard layer and forms a flexible abutment for the wound material web. * A preferred embodiment of the invention is characterized in that the padding consists of fibers flocked onto the surface. These fibers are sufficient to produce the desired cushioning effect.
Im folgenden wird ein in der Zeichnung dargestelltes Ausführungsbeispiel der Erfindung erläutert; die einzige Figur zeigt eitlen Querschnitt durch einen rohrförmigen Wickel kern.In the following, an embodiment of the invention shown in the drawing is explained; the only figure shows a cross-section through a tubular winding core.
Der dargestellte Wickelkern besteht aus einer zu einem Rohr aufgewickelten Pappbahn, von der nur die innere Lage 1 mit innerer Endkante 2 und die äußere Lage 3 mit äußerer Endkante 4 dargestellt sind. Die anderen Lagen sind mit gestrichelten Linien angedeutet. Alle Lagen der Pappbahn sind miteinander verbunden. Auf der gesamten äußeren Oberfläche des Wickelkerns ist ein Polster 5 angeordnet, das bei der dargestellten Ausführung aus auf die Oberfläche aufgeflockten Fasern besteht. Das Polster 5 erstreckt sich insbesondere auch über den Bereich der äußeren Endkante 4 und verhindert durch seine nachgiebigen Eigenschaften, daß die Erhöhung der Endkante 4 über die Oberfläche des Wickelkerns oder die Endkante der Materialbahn sich auf den inneren Lagen einer auf den Wickelkern aufgewickelten empfindlichen Material bahn, z. B. aus Samt oder Kunststoffolie, nicht mehr abbildet.The winding core shown consists of a cardboard web wound up into a tube, of which only the inner layer 1 with inner end edge 2 and the outer layer 3 with outer end edge 4 are shown. The other layers are indicated with dashed lines. All layers of the cardboard web are connected to one another. A cushion 5 is arranged on the entire outer surface of the winding core, which in the embodiment shown consists of fibers flocked onto the surface. The cushion 5 extends in particular over the area of the outer end edge 4 and, thanks to its flexible properties, prevents the elevation of the end edge 4 above the surface of the winding core or the end edge of the material web from no longer being reflected on the inner layers of a sensitive material web wound up on the winding core, e.g. made of velvet or plastic film.
