  • Patent number: 6553881
    Abstract: The configuration enables the introduction of a material web, which can be divided up into material sub-web strands, into the conveying paths of an angle-bar superstructure of a rotary printing machine. A slitting arrangement, which can be positioned in a variable manner in the angle-bar superstructure, and web drawing-in devices and components for attaching the material web or the material sub-web strands to the web drawing-in devices are provided. Assigned to the web-running plane is an adjustable advancement element which bridges a contact-pressure gap in relation to a mating roller, accommodated in the angle-bar superstructure, and by way of which one of the material sub-web strands or can be attached to an introduction element which can be moved into the web-running plane.

  • Patent number: 6147635
    Abstract: A timer for an A/D converter generates a request signal for A/D conversion by the A/D converter. In addition to the usual request signal, the timer produces a further signal which is used, before one cycle of the timer has elapsed, to block the A/D converter for low-priority requests from other requesting devices and to reserve it for the timer. In this manner, the signal to be converted from the timer can be sampled at reproducible, equidistant instants without having to wait for the end of the last conversion.
