    摘要： A method for perforating a sheet material provides for a perforating die located intermediate two orbital rollers. The two orbital rollers move in orbital paths in the same orbital direction at the same speed and in positions which are 180 degrees apart. Each roller acts as a temporary storage input and output in opposite phase from each other so that incoming sheet material is alternately stored and dispensed as a loop on the orbital roller. Since the rollers are out of phase, this permits a segment of the sheet material to be stopped intermediate the orbital rollers so that the perforating die can act on the stopped segment.

    摘要： 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.
