In a packaging machine a planar web of packaging laminate is reshaped to an annular tube of packaging laminate by means of a forming section, which comprises, - a bending roller, designed to deflect the path of the planar web, - a lower forming tool, downstream the bending roller, defining an aperture through which the packaging laminate is led and given an annular shape, and - guide means between the bending roller and the lower forming tool for guiding the path of the packaging laminate. The forming section is characterized in that the bending roller is arranged slidably on a bar extending in the direction of the web path upstream the lower forming tool, such that the forming distance between the lower forming tool and the bending roller may be varied by moving the latter along the bar. |
