Abstract

The sheet transporting device of the invention includes: a transferring device (64) adapted to transfer a sheet (30), a conveying device (66; 66A) for conveying a sheet transferred from the transferring device (64) onto the conveying device, and a controlling means (76) adapted to control the speed of the conveying device (66; 66A) and defining a transfer cycle (CT). The controlling means (76) is adapted to slow down the conveying device (66) when a sheet is conveyed by the related conveying device and to accelerate the conveying device when no sheet is present on said conveying device. The invention can be used for the cutting devices of rotary printing machines.
