Method for controlling the tension of a sheet and/or the register

摘要

The method involves processing a product web i.e. paper (101), in a processing device. Elasticity modulus of a material of the web is changed by dampness entry into the material of the web and/or dampness discharge from the material of the web. A variable e.g. control parameter, input variable, precontrol value and reference value, assigned to the dampness entry into the material of the web and/or the dampness discharge from the material of the web is considered during controlling a web tension and/or a register. Independent claims are also included for the following: (1) a computer program with a program code unit for executing controlling steps of a method for controlling a web tension and/or a register in a processing machine (2) a computer program product with a program code unit for executing controlling steps of a method for controlling a web tension and/or a register in a processing machine.
