ABSTRACT:
The web or sheet feeding apparatus of a reprographic machine consists of first and second sets of endless bands respectively trained over co-operating pairs of driven and driving rollers. These rollers are arranged so that adjacent reaches of the bands of the two sets extend parallel to each other to define a passageway along which web or sheets are fed by the moving bands. One or more micro-switches controlling the operation of the apparatus are mounted between adjacent passage-defining reaches of bands of the first set and have actuating arms which extend into the passageway for actuation by the web or sheets. To accommodate these actuating arms, the passage-defining reaches of the bands of the second set adjacent the micro-switches are passed below spindles so as to deflect these reaches away from the micro-switches. The passage-defining reaches of the other bands of the second set pass between the spindles and the adjacent reaches of the bands of the first set and so are not deflected.
