Method and apparatus for treating continuous sheet material

Abstract

The method for treating continuous sheet material for use in the manufacture of rod-shaped articles comprises the steps of providing a continuous sheet material comprising a crimping structure running in a longitudinal direction of the continuous sheet material. It further comprises the step of providing a first roller and a second roller, the first roller and the second roller comprising a plurality of circumferentially running cams, the circumferentially running cams of the first roller and the circumferentially running cams of the second roller engaging each other. The method further comprises the step of guiding the continuous sheet material comprising the crimping structure between the circumferentially running cams of the first roller and of the second roller. Thereby the continuous sheet material comprising the crimping structure is provided with a wavelike structure, the wave-like structure runs in a longitudinal direction of the continuous sheet material and overlays the crimping structure.
