A method for determining the optimum procedure for a job change on a printing-material processing machine () with at least one control computer. The data of a first machine job is compared to the data of a subsequent machine job using a control computer, and the comparison is used to establish an order of the operations to be carried out during the job change. Also provided is a device for determining the optimum procedure for a job change on a printing-material processing machine () with at least one control computer. The control computer is intended to compare the data of a first machine job to the data of a subsequent machine job, and to use the comparison to establish an order of the operations to be carried out during the job change.

Method and device for optimizing a job change

A device and a method for lateral alignment of a sheet () in a sheet processing machine, in which the sheet () is movable essentially across its direction of transport () into an alignment position (); a side pull lay device is used for moving the sheet () into the alignment position (). The side pull lay device has at least two side pull lays () which are activatable independently of one another for transporting a sheet () toward the alignment position (). The method includes that at least two side pull lays () of the side pull lay device are activated independently of one another for transporting a sheet () toward the alignment position ().

Independently activatable side pull for lateral alignment of a sheet

A method for the register-true alignment of sheets ( ) before the transfer to a sheet-processing machine with the assistance of a carrier ( ) that is movable in the machine cycle and is driven as a function of a signal, in order to feed the sheets individually to an aligning stop. To permit exact and reliable alignment even at high machine speeds with an uncomplicated mechanism, the signal is generated when a sheet edge ( ) to be fed passes a predetermined location between the carrier ( ) and aligning stop ( ), and in response to the signal, the carrier performs a preset movement, identical from sheet to sheet, by which the carried-along sheet ( ) is fed to the aligning stop with a speed greater than zero, but substantially less than the maximum sheet speed during the feeding movement. The method is particularly suitable for side-edge alignment, but is also suitable for leading-edge alignment.
