    摘要： 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).

    摘要： A rotary cutting apparatus comprises a cutter drum having at least one cutting member and an anvil dram having a rotary axis, arranged in a cutting relationship to one another, and a pressure actuating means for subjecting pressure on said cutting member in relation to said anvil drum, said pressure actuating means comprises a pair of levers rotatable about at least one hinge means having a horizontal axis, said horizontal axis being parallel to but non- concentric with said rotary axis, wherein a bearing housing is arranged on each axial side of the anvil drum. In accordance with the invention, a frame is provided for supporting the cutter drum and the anvil drum in a rotatable relationship, wherein said pair of levers are releasably connected to the bearing housing, respectively, in such a way that the anvil dram is allowed to be removed from the frame.
