Abstract

Vorrichtung und Verfahren zum Bewegen eines Empfangselements (S) in eine ausgerichtete Beziehung mit einem sich bewegenden, bildtragenden Element in einem Registersystem (100). Die Vorrichtung und das Verfahren berücksichtigen Empfangselemente (S), die außerhalb eines normalen betrieblichen Zeitfensters an dem Registersystem (100) eintreffen. Wenn ein Empfangselement (S) zu spät eintrifft, wird das Empfangselement (S) auf eine Geschwindigkeit (230) beschleunigt, die höher als die des sich bewegenden, bildtragenden Elements ist, und zwar für eine Zeitdauer, die ausreichend bemessen ist, um die verspätete Ankunft zu berücksichtigen. Das Empfangselement (S) wird dann auf eine Geschwindigkeit verzögert, die im Wesentlichen gleich der Bildtransportgeschwindigkeit (220) ist.Apparatus and method for moving a receiving element (S) into aligned relationship with a moving image bearing element in a register system (100). The apparatus and method consider receiving elements (S) that arrive at the register system (100) outside of a normal operational time window. When a receiving element (S) arrives too late, the receiving element (S) is accelerated to a speed (230) higher than that of the moving image-bearing element for a time sufficiently longed for Arrival to be considered. The receiving element (S) is then delayed to a speed substantially equal to the image transport speed (220).

Wenn das Empfangselement (S) zu früh eintrifft, wird das Empfangselement (S) für eine Zeitdauer angehalten, die ausreichend bemessen ist, um die zu frühe Ankunft zu berücksichtigen. Das Empfangselement (S) wird dann auf die Bildtransportgeschwindigkeit (220) beschleunigt.

Figure imgaf001
If the receiving element (S) arrives too early, the receiving element (S) is stopped for a period of time sufficient to accommodate the early arrival. The receiving element (S) is then accelerated to the image transport speed (220).
