Abstract: A roller for guiding a sheet (101) by friction has a contact surface (2) designed to be in contact with the sheet (101), the contact surface (2) having, overall, a shape of revolution when the roller (1) is at rest, a central portion (6) configured to mechanically connect the roller (1) to a rotating drive element, and a deformation portion (10) located between the contact surface (2) and the central portion (6), the deformation portion (10) being configured to deform elastically when the roller (1) guides the sheet (101) by friction.
The deformation portion (10) comprises at least one cut (12) extending from the contact surface (2) to the central portion (6), the cut (12) being arranged such that the deformation portion (10) comprises at least one elastically deformable segment (16).

Abstract: A method for locally modifying a structure of a paperboard. A penetrating region (114) of the paperboard (110) is penetrated by laser radiation (102) such that moisture in the penetrating region (114) evaporates for locally modifying the structure of the penetrating region (114) e.g. by weakening the paperboard at the region and for deforming it there.
