    • 1. A rotary cutting apparatus, comprises a frame (4), a first rotary device, such as a rotary cutter (6) or a rotary anvil (8), comprising a first shaft (10 or 24) concentrically arranged about a first rotational axis (A-A or B-B) and a first drum (12 or 26), such as an anvil drum (26) or a cutter drum (12) concentrically arranged on said first shaft , said first shaft (10 or 24) being provided with a first pair of bearing housings (14 or 30) arranged on either sides of said first drum (12 or 26), a second rotary device comprising a second shaft (10 or 24) concentrically arranged about a second rotational axis (A-A or B-B), and a second drum (12 or 26), such as an anvil drum (26) or a cutter drum (12) concentrically arranged on said shaft (10 or 24), said second shaft being provided with a second pair of bearing housings (14 or 30) arranged on either sides of said second drum (12 or 26), said first and second rotary devices being arranged in said frame (4) in such a way that said first and second axes (A-A, B-B)are substantially horizontal and substantially in the same vertical plane; said second shaft (10 or 24) being connected to the frame (4) via said second pair of bearing housings (14 or 30); said first shaft(10 or 24) being associated with said frame (4) via said first pair of bearing housing (14 or 30), said first pair of bearing housings being movable relative to said frame (4) in a transverse direction to said first rotational axis (A-A or B-B) by means of a force means (38).According to the invention, means is provided for passive vibration attenuation of at least said first shaft (10 or 24), said means for passive vibration attenuation (46) comprising a mass damper (47) having a housing (48) and a damping body (50) movably arranged inside said housing (48), wherein said mass damper (47) is associated with said first pair of bearing housings (14 or 30).

    • L'invention concerne un dispositif de couplage à vitesse angulaire variable.
      Le dispositif selon l'invention permet un couplage de vitesse angulaire entre un bras d'entrée (41) et un bras de sortie (47) commandant un organe (2, 3, 4, 5) destiné à être mis en engagement avec un support mobile entraîné à vitesse sensiblement constante, ledit dispositif comprenant une paire de cames conjuguées dont les profils respectifs permettent un déplacement angulaire relatif entre le bras d'entrée (41) et le bras de sortie (47), de manière à conférer audit organe une vitesse linéaire sensiblement identique à la vitesse du support mobile, lorsque ledit organe est en engagement avec ledit support mobile.:
