Abstract
An anvil drum for a rotary cutting apparatus having a rotary axis comprises an axle on each axial side of the anvil and concentric with the axis. Each of the axles is adapted to receive a bearing, and an anvil surface substantially concentric with the rotary axis. A reference portion is provided including an axial reference surface coaxial to the axis and a radial surface perpendicular to the axis. At least one connection device is provided for connecting a cover member on each axial side of the anvil so as to cover the bearing, respectively. An anvil assembly is further provided with such an anvil drum and the bearings, each cover member being provided with a blind opening adapted arranged coaxially with respect to the axis.
