Abstract
The present invention relates to a method of guiding a web with a shifting path of the web to a substantially constant centration point. It comprises the steps of providing a web with a shifting path of the web from a source of the web, measuring upstream of said centration point, the position and/or orientation of said web by a sensor arrangement, and guiding said web to said centration point in accordance to the measurement results. The present invention advantageously relates to operations in the manufacturing of absorbent articles such as unwinding web rolls that are wound in a shifted manner, in particular spirally wound web rolls, and removing web from containers of loose web material. The invention also relates to a device for the execution of the method.
