Description

Einspannvorrichtung f ür zum Durchschreiben bestimmte Blätter und Formulare. Bei Einspannvorrichtungen, wie sie z. B. bei dez Durchsichreibebuchhaltung benutzt werden, ist es wichtig, die eingespannten Blätter unter den Klemmschienen unter möglichst gleichmäßigem Druck zu halten. Die Klemmschienen können deshalb mit Gununipuffern ausgerüstet sein. Solche Gumrnipuffer erfüllen aber ihren Zweck nur dann, wenn Unterlagsplatte und Klemms,chiene vollständig gerade sind und die Gununipuffer mit ihrer Aufsetzflädie gleichfalls in derselben Ebene. liegen, damit alle Gummipuffer zum gleichmäßigen Andruck auf das, #eingeklemmte Papierblatt kommen. Tritt jedoch die geringste Krümmung der Unterlagsplatte ein, dann wird der Andruck über die Länge der Klemm.-schiene ungleich, und das Papier könnte bei =beabsichtigtem Zug sich entweder verschieben oder -ar stellenweise ausreißen.Chuck f or by writing to certain sheets and forms. In jigs as they are, for. B. are used for decontrol bookkeeping, it is important to keep the clamped sheets under the clamping rails under the most even pressure possible. The clamping rails can therefore be equipped with Gununi buffers. Such rubber buffers only fulfill their purpose, however, if the base plate and clamping rail are completely straight and the gununi buffers with their mounting surfaces are also in the same plane. so that all rubber buffers come to press evenly on the clamped paper sheet. However, if there is the slightest curvature in the base plate, then the pressure over the length of the clamping rail will be unequal, and the paper could either move or tear in places with the intended pull.

Vorä,eende Erfindung ermöglicht eine genaue Einstellung der Gummipuffer auch bei, nicht ebener Unterlagsplatte bzw. nicht vollständig geradex Klemmschiene dadurch, daß jeder Gummipuffer in ein-er sch#aubbaren Hülse angeordnet ist, die an ihrem Kopfende. einen von innen nach- außen führenden Kanal besitzt. Mittels dieser Rülse läßt sich jeder- Gununipuffer einzeln genau einstellen.The previous invention enables precise adjustment of the rubber buffers even if the base plate is not level or the clamping rail is not completely straight in that each rubber buffer is arranged in a push-in sleeve which at her head end. has a channel leading from the inside to the outside. Means Each Gununipuffer can be individually adjusted to this sleeve.

Die Erfindung ist auf der Zeichnung 111 einem Atisführungsbeispiel dargestellt, und zwar zeigt Albb. i den Gunimipuff-er mit Metallhülse, für sich, Abb. 2 einen Längsschnitt durch die umgekehrte Klemnischienk mit einem eingesetzten PuffeT und Abb. 3 eine Einspannvorrichtung in Oberansidlit mit hochgeklappter Nebenschiene, sv daß die Gummipuffer von der Seite sichtbar sind.The invention is shown in the drawing 111 of an exemplary embodiment, namely Albb. i the Gunimipuff-er with metal sleeve, for itself, Fig. 2 a longitudinal section through the inverted Klemnischienk with an inserted PuffeT and Fig. 3 a clamping device in upper view with folded up side rail, sv that the rubber buffers are visible from the side.

In eine Hülse a ist ein Gummipuffer b einvulkanisiert oder eingeleimt. Die Hülse a be- sitzt am Kopfende einen Kanal c, durch den beim Einvulkanisieren -oder Einkleben des Gummipuffers, b die Luft oder ilberflüssiger Klebstoff austreten kann. Die Hülse a besitzt am Umfang Gewihde d, mit dem sie in die Gewindelöcher g, der Klemmsichiene / eingeschraubt werden kann. Eine Gegenmutter e dient zur Sicherung der Hülse a mit Pufferb in der eingestellten Höhenlage. Die Klemmschiene (Abb. 2) zeigt Über ihre Länge sechs Gewindelöcherg., in deren einem bereits. eine Hülsea mit Pufferb eingeschraubtist. Die Hülsea selbst kann ausi beliebigem Werikstog bestehen. A rubber buffer b is vulcanized or glued into a sleeve a. The sleeve a loading sits at the head of a channel c, by gluing -or- during vulcanization of the rubber buffer, the air or adhesive ilberflüssiger b can escape. The sleeve a has thread d on the circumference, with which it can be screwed into the threaded holes g, the clamping rail /. A lock nut e is used to secure the sleeve a with buffer b in the set height. The clamping rail (Fig. 2) shows six threaded holes over its length, one of which already has. a sleeve a with a buffer b is screwed in. The sleeve itself can consist of any Werikstog.
