  • Printing press with a dynamic expansion band adjusting mechanism
    Patent number: 5313883
    Abstract: A self-locking mechanism (10) for selectively dynamically adjusting expansion bands (12) of a running cylinder (11) of a rotary printing press during rotation includes a cylindrical adjustment member (30, 72) with a diameter substantially the same as the diameter of the running cylinder which engages a band box (22, 80) rotating with the running cylinder (11) to make the selected adjustments in response to rotation of cylindrical adjusting member (30, 72) at a speed different from the speed of the running cylinder (11). The speed difference is produced by a differential (52, 75) stationary with respect to the running cylinder (11) which engages the cylindrical member (30, 72) and the running cylinder (11). The cylindrical adjusting member (30, 72) is mounted to the running cylinder (11) on an interrupted journal (35). The cylindrical adjusting member (30) has an inner engagement surface (38) for engagement with the band box (22) and another engagement surface (39) for engagement with the differential.
