Description
Einspannvorrichtung mit Einspannscheiben und Bremse für die ablaufenden Papierrollen der Vervielfältigungsvorrichtungen. Für das richtige Arbeiten mit Vervielfältigungsvorrichtungen ist es von Bedeutung, däß nicht Rollen verschiedenen Umfanges oder Gewichtes, sondern nur die vorher jeweils berechneten und in Betracht kommenden Papierrollen zur Verwendung gebracht werden können. Diese Bedingung soll durch den Gegenstand der vorliegenden Erfindung erfüllt werden. Er ist in der Zeichnung in einer Ausführungsform in. Abb. i in Seitenansicht und`..AufriB dargestellt, während Abb. 2 die einander gegenüberstehenden Stirnflächen der Wickelwalze für die Papierrolle und der Einspannscheibe zeigt. Die Stirnfläche 3 der Kernwalzen ist mit Vertiefungen oder Erhöhungen: in Form von Figuren oder Zeichen versehen. Die Einspannscheibe q. trägt den Vertiefungen oder Erhöhungen bei 3 entsprechende Erhöhungen oder Vertiefungen. Die Scheibe 4 kann gegen die Kernwalze gedrückt und von ihr abgezogen werden. Im ersteren Falle treten die Erhöhungen in die Vertiefungen, die Papierrolle wird eingespannt.. Im letzteren Fall wird sie freigegeben. Gegen die Handscheibe d drückt eine Feder 7, die zugleich als Bremsfeder wirkt.Clamping device with clamping disks and brake for the expiring Paper rolls of the duplicating devices. For working properly with duplicating devices it is important that not roles of different size or weight, but rather only the previously calculated and considered paper rolls are used can be brought. This condition is intended by the subject matter of the present Invention are met. It is shown in one embodiment in the drawing. i shown in side view and '.. AufriB, while Fig. 2 the opposite Shows end faces of the winding roller for the paper roll and the clamping disc. The end face 3 of the core rolls is depressions or elevations: in the form of Figures or characters. The clamping disc q. carries the wells or Elevations at 3 corresponding elevations or depressions. The disc 4 can pressed against the core roller and withdrawn from it. Step in the former case the elevations in the depressions, the paper roll is clamped. In the latter Case it will be released. Against the hand disk d presses a spring 7, which at the same time acts as a brake spring.
