Abstract
A method and mechanism for assembling paper machine filled rolls including a lower support with a cylinder and a piston for receiving a roll mandrel, vertically extending bolts for supporting a plate to press on relatively soft disks slid over the mandrel end, a variable speed vibration generator connected to the upper end of the mandrel with a vibration speed control so that the mandrel can be vibrated through natural frequencies and harmonics thereof with a device to monitor mandrel vibration frequency and displacement so that the disks on the mandrel compact more effectively and the friction between the disks and mandrel is reduced.
