Abstract
The invention relates to apparatus for treating a multi-panel or multi-sheet web of paper or similar electrostatically chargeable material. A multi-layer web of such material is advanced toward and through at least one cutter to yield a succession of stacks which are ready for assembly into piles and/or for other processing. The arrangement for moving the web and there-upon the stacks lengthwise includes a first unit up-stream and a second unit downstream of the cutter, and an ionizing unit is installed adjacent the path of the web and stacks, either between the first moving unit and the cutter or between the cutter and the second moving unit. In either event, the ionizing unit is closely adjacent the cutter. If the stacks are to be assembled into a succession of piles downstream of the second moving unit, the apparatus further comprises an electrostatic discharging device in the region of the pile forming station.
