The invention relates to a pressure roller device for a wound web material cutting machine comprising a support bar (10) on which a pressure roller (20) is rotatably mounted, said pressure roller being formed by a plurality of adjacent pressure segments (25) which each have an outer cylindrical surface (21) opposite a reel (30). The invention includes guide means for guiding the movements of the pressure segments (25) in a radial direction in relation to the support bar (10) and thrust means for individually and independently thrusting each pressure segment (25) guided in the guide means against the reel (30). The outer cylindrical surfaces (21) of the pressure segments (25) can therefore be positioned off-centre in relation to a central line (15) of the support bar (10) with different eccentricities individually determined by the contact between the outer cylindrical surface (21) of each pressure segment (25) and the reel (30).
L'invention concerne une barre support (10) sur laquelle est monté rotatif un rouleau de presse (20) composé de plusieurs segments de presse (25) adjacents, chacun d'eux avec une superficie extérieure cylindrique (21) faisant face à une bobine (30). Le dispositif de l'invention comprend également des éléments de guidage destinés à guider les déplacements des segments de presse (25) dans une direction radiale par rapport à la barre support (10) et des éléments de poussée destinés à pousser de façon individuelle et indépendante chaque segment de presse (25) guidé par les éléments de guidage contre la bobine (30). Ainsi les superficies extérieures cylindriques (21) des segments de presse (25) sont susceptibles de rester décentrés par rapport à une ligne centrale (15) de la barre support (10) avec des excentricités différentes déterminées de façon individuelles par le contact de la superficie extérieure cylindrique (21) de chaque segment de presse (25) avec la bobine (30).
