Abstract (en)
[origin: EP2177118A1] The method involves providing a wrapping material strip i.e. cigarette paper (14), with zones in which oxygen permeability in comparison to regions of the wrapping material strip outside the zones. An edge region of the wrapping material strip is mechanically changed, and an adhesive is applied on the wrapping material strip for manufacturing a rod-shaped article of a tobacco processing industry. The edge region is abrasively processed by roughening or perforating. A material is stripped by the edge region by an energy effect by laser beams (28, 29). An independent claim is also included for a tobacco processing industry device for processing a wrapping material strip for a rod-shaped article of a tobacco processing industry.
