Pneumatically driven rotary plates can be used to support sidelays in sidelay bridges and align sheets during sheet transport.
Sidelay bridges make it possible to position 2 rotary plates as far apart as possible. The plates rotate in such a way as to tauten the print material between them, thereby ensuring that the sheet runs smoothly. Sheet tautening is a particularly useful means of ensuring correct sheet arrival when working with thin paper.
The arrangement of one or more pneumatic rotary plates in series or across the width of the sheet facilitates the alignment of individual sheets during sheet transport.
