Description
Der Gegenstand der durch das Patent 1090 618 geschützten älteren Erfindung ist eine Einrichtung zum Einklemmen des Bandendes an einer spreizbaren Haspeltrommel, zwischen deren Segmenten radial verstellbare Keilleisten liegen, die die Trommeloberfläche im Spreizzustand zu einer annähernd lückenlosen Zylinderfläche ergänzen, wobei das Bandende beim Spreizen der Trommel zwischen Greifflächen selbsttätig einklemmbar ist. Insbesondere schützt das ältere Patent eine Ausführungsform, bei der die eine der Greifflächen einen Vorsprung hat, während die andere abgefedert ist.The subject matter of the prior invention protected by patent 1,090,618 is a device for clamping the end of the tape on an expandable reel drum, between its segments radially adjustable V-ledges, which approximate the drum surface in the expanded state Complete the uninterrupted cylinder surface, with the end of the tape between gripping surfaces when the drum is spread is automatically clamped. In particular, the earlier patent protects one embodiment one of the gripping surfaces has a protrusion, while the other is cushioned.
Diese ältere Erfindung wird nun erfindungsgemäß dadurch verbessert, daß die abgefederte Greiffläche der Keilleiste von einem auf dieser befestigten Gummikissen gebildet wird. Wenn der Vorsprung der einen Greiffläche das Blechband an das Gummikissen anpreßt, dann wird in das Band eine entsprechende Vertiefung eingedrückt, und diese Vertiefung wird in das Kissen hineingepreßt. Dadurch wird das Bandende zuverlässiger eingeklemmt, als es der Fall ist, wenn die abgefederte Greiffläche der Keilleiste aus Metall besteht. Das wirkt sich besonders vorteilhaft aus, wenn die vorspringende Rippe ungleichmäßig abgenutzt ist und wenn mehrere Blechbänder nebeneinander eingeklemmt werden und diese Bänder ungleichmäßig dick sind.This older invention is now improved according to the invention in that the cushioned gripping surface the V-ledge is formed by a rubber cushion attached to it. If the lead of the a gripping surface presses the sheet metal band against the rubber cushion, then a corresponding one is inserted into the band Depressed depression, and this depression is pressed into the pillow. This will be the end of the tape more reliably clamped than is the case when the sprung gripping surface of the V-ledge is off Made of metal. This is particularly advantageous if the protruding rib is uneven is worn and when several metal strips are jammed next to each other and these strips are uneven are thick.
Bei einer Greifzange einer Blechstreckbank ist es bereits bekannt, das Klemmbackenwiderlager als Gummikissen auszubilden, in das sich das Blechband beim Klemmvorgang eindrückt, um ein von den Unregelmäßigkeiten des Blechbandes unabhängiges, gleichmäßiges Anpressen der Klemmbacken an die Metallbandoberfläche zu erreichen. Dem vorliegenden, auf die Verbesserung der älteren Erfindung gerichteten Zusatzpatent kommt daher nur die Bedeutung eines nachgeholten echten Unteranspruchs zu.In a gripping pliers of a sheet metal stretching bench, it is already known to use the clamping jaw abutment as Form rubber cushions, into which the sheet metal band is pressed during the clamping process, in order to avoid the irregularities independent, even pressing of the clamping jaws against the metal strip surface. The present one Therefore, only the meaning is given to the additional patent aimed at improving the older invention a real subclaim that has been made up for.
Vorzugsweise ist das Gummikissen durch eine Unterlage aus einem Werkstoff versteift, der härter als der Werkstoff des Gummikissens ist.The rubber cushion is preferably stiffened by a base made of a material that is harder than the material of the rubber cushion.
