Abstract

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).

Claims (12)

1.- A pressure roller device for a wound web material cutting machine comprising in combination:
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), each of said pressure segments (25) having an outer cylindrical surface (21) opposite an outer cylindrical surface of at least one reel (30);
guide means adapted for guiding movements of the pressure segments (25) in a radial direction in relation to said support bar (10); and thrust means adapted for individually and independently thrusting each pressure segment (25) guided in said guide means against said at least one reel (30), whereby said 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 individually determined by the contact of the outer cylindrical surface (21) of each pressure segment (25) with an outer cylindrical surface of the reel (30).
2.- The device according to claim 1, characterized in that said thrust means comprise an expandable element (60) driven by pressurized fluid for individually thrusting the pressure segments (25) with a common pressure.
3.- The device according to claim 2, characterized in that said guide means comprise two parallel planar outer faces (11) formed in the support bar (10) and in sliding contact with corresponding parallel planar inner faces (41) formed in a cavity (42) of a core (40) on which the pressure segment (25) rotates such that said core (40) together with the pressure segment (25) can be moved radially in relation to the support bar (10).
4.- The device according to claim 3, characterized in that said thrust means further comprise for each pressure segment (25) at least one thrust member (50) located between the support bar (10) and the core (40) of the pressure segment (25), said expandable element (60) being located along the support bar (10) between the support bar (10) and said thrust members (50) for individually thrusting the thrust members (50) against the corresponding cores (40) with a common pressure, and therefore radially moving the corresponding pressure segments (25) in relation to the support bar (10).
5.- The device according to claim 4, characterized in that the support bar (10) has a housing (12) formed therealong having a longitudinal opening located between said two planar outer faces (11), and each of the thrust members (50) comprises a guide portion (51) inserted in said housing (12) of the support bar (10) such that it can slide outwardly and inwardly thereof in a direction parallel to the two planar outer faces (11) of the support bar (10), and a projecting portion (52) adapted for applying pressure against an inner surface of said cavity (42) of the core (40) of the pressure segment (25) when said thrust member (50) is moved outwardly from the housing (12).
6.- The device according to claim 5, characterized in that said expandable element (60) is in the shape of an expandable sleeve (60) arranged in said housing (12) along the support bar (10) between a bottom surface of the housing (12) and an end surface of each of said guide portions (51) of the thrust members (50), said expandable sleeve (60) being able to be connected to a pressurized fluid source through valve means associated to the support bar (10).
7.- The device according to claim 6, characterized in that the thrust member (50) has protuberances (53) formed next to an inner end of the guide portion (51), and said longitudinal opening of the housing (12) of the support bar (10) has flanges interfering with said protuberances (53), so that the thrust member (50) is retained in the housing (12) with limited sliding possibility.
8.- The device according to claim 7, characterized in that in at least one end of the support bar (10) projecting from the pressure roller (20), the longitudinal opening of the housing (12) has a widening (13) with a sufficient size to allow the passage of the guide portions (51) of the thrust members (50).
9.- The device according to claim 8, characterized in that inside a portion of the housing (12) opposite said widening (13) a stop (14) is fixed for retaining the thrust members (50) inside the housing (12) of the support bar (10) against a movement in the direction of the central line (15).
10.- The device according to claim 9, characterized in that each pressure segment (25) is rotatably mounted on its corresponding core (40) by means of a pair of bearings (26), which are further adapted for retaining the pressure segment (25) on its corresponding core (40) against a movement in an axial direction.
11.- The device according to claim 10, characterized in that between each two adjacent pressure segments (25) at least one separator (27) is arranged, said at least one separator (27) being fixed to the core (40) of one of the two adjacent pressure segments (25) and in sliding contact with a side surface of the core (40) of the other one of the two adjacent pressure segments (25).
12.- The device according to claim 11, characterized in that next to each of the two pressure segments (25) located at the ends of the pressure roller (20) at least one stop (28) is arranged, said at least one stop (28) being fixed to one of the planar outer faces (11) of the support bar (10) and in sliding contact with a side surface of the core (40) of the corresponding pressure segment (25).
