PRESSURE ROLLER DEVICE FOR A MACHINE THAT IS USED TO CUT WOUND LAMINAR MATERIAL

摘要

The invention relates to a pressure roller device for a machine that is used to cut wound laminar material. The inventive device includes a support bar (10) to which a pressure roller (20) is rotatably mounted, said pressure roller comprising a plurality of adjacent pressure segments (25) which each have an outer cylindrical surface (21) that is disposed opposite a roll (30). The invention also includes guide means for guiding the movements of the pressure segments (25) radially in relation to the support bar (10) and push means for individually and independently pushing each pressure segment (25) that is guided by the guide means against the roll (30). The outer cylindrical surfaces (21) of the pressure segments (25) can be positioned off-centre in relation to a central line (15) of the support bar (10) with different eccentricities which are each pre-determined by the contact between the outer cylindrical surface (21) of each pressure segment (25) and the roll (30).
