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.
A micro-switch operated apparatus for feeding web material, including webs and sheets, comprising first and second sets of endless bands respectively trained around co-operating pairs of driven and driving rollers, the opposed reaches of the bands in each set being movable in the same direction and defining a passageway for conveying web material between the bands, a deflector fixedly located with respect to the rotative axes of said rollers and disposed in said passageway, said deflector engaging and deflecting the passageway defining reach of at least one of the bands of the second set away from the bands of the first set, and a micro-switch mounted fixedly with respect to said roller axes and located laterally between adjacent bands of the first set with an actuating member of the micro-switch disposed in the space between the deflected reach of the bands of the second set and the opposed reaches of the bands of the first set.
