Abstract (en)
The method involves determining a web tension (S1) of a web tension section (111), which is provided in a product web (101), based on the modulus of elasticity of product web materials, the speed of a transport axle and the drive torque of the axle. The drive torque of the axle depends on the diameter of the axle. Web tensions (S2, S3, S4) of web tension sections (112, 113, 114) are determined based on the determined web tension (S1). The change in the expansion characteristics of the product web is evaluated. Independent claims are also included for the following: (1) a processing unit for determining the web tension of the web tension section (2) a computer program with a program code for determining the web tension of a web tension section (3) a computer program product with a program code structure for determining the web tension of a web tension unit.
