Abstract: Apparatus for feeding a continuous web of photosensitive paper into a reprographic machine so that the leading edges of the paper and a transparent master sheet to be copied are co-incident as they enter exposure and developing stations, and to ensure that the tail end of the paper is cut, during continuous forward movement of the leading edge, so that the trailing edge of the severed paper co-incides with the tail end of the master sheet. The feed path of the paper includes a curved portion defined by an arcuate-section guide and a concentrically mounted roller. A loop of paper is formed by moving the roller out of the guide and the rear end of the paper is then held stationary and cut by a guillotine while the paper forming the loop is continuously fed forward. The timing of the feeding and cutting operations on the paper is controlled by micro-switches actuated by the leading and trailing ends of the master sheet.

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.
