In an elongate exposure assembly in a copying machine, an illumination cylinder is nested in an array of elongate rolls which cooperate with endless elastic belts to drive the cylinder and feed the originals and copy sheets around the same. The rolls are of minimum stiffness, but are nevertheless capable of acting to feed the sheets correctly by reason of one or more self-locating spreader plates arranged at appropriate positions along their lengths to hold the rolls locally in the proper relationship to each other. Each such plate is provided with a throat opening into the cylinder receiving opening to provide access for the sheets to be exposed.
