Device for optimising sheet location at front stop edge of printing machine - comprises feed table with conveyor belts beyond which is connected locator working in time with printing machine

摘要

The running speed of the components (9,11,3a,4b) transporting the scaled flow of paper sheets is adjustable to the speed of the printing machine. The phase of the work cycle of the locator (2) is adjustable in relation to that of the printing machine (1), dependent upon the speed variation. In the drive sequence between the printing machine and the locator is a positioning gear (21), whose output is phase-adjustable in relation to its input. In the drive sequence, leading to the components transporting the scaled flow of paper, an adjustable transmission gear (17) is provided. Both these gears are stagelessly adjustable. ADVANTAGE - To obviate twisting and curling of the leading edges.
