摘要： The invention relates to a cylinder (54) for transporting a flat substrate, said cylinder comprising a cylindrical base body (70) which has a cylindrical surface (74) consisting of a first material, and openings (82) leading out onto the cylindrical surface. The transport cylinder (54) comprises a sleeve (72) arranged on the cylindrical surface (74), said sleeve having a plurality of through-holes (92) aligned with at least some of the openings (82). The sleeve (72) has an outer surface (88) consisting of a second material. The surface energy of the outer surface (88) is lower than the surface energy of the first material. The invention is applicable to rotary presses.

摘要： 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.
