Abstract
A reel-up in a paper machine has two primary arms, each of which has an elongate beam that is pivotably journalled on stand members in the reel-up, and a carriage that is displaceably journalled on the beam and has a gripper on its side that faces the surface winding drum for gripping a reeling drum collected from a top drum stock. Each beam has a free end located at a lesser distance from the pivot axis of the primary arm than the distance between the pivot axis and the empty reeling drum located in the drum stock. Each carriage can be displaced outwards from the beam so that the gripper is beyond the free end of the beam at a distance from the free end so as to assume a position for receipt of a reeling drum. One of the carriages carries a central drive device with a coupling device for axial movement into operating engagement with a coupling device on one end of the reeling drum, so as to rotate the reeling drum and bring its peripheral speed up to the speed of the traveling paper web while the primary arms are lowering the reeling drum to engage it with the surface winding drum of the reel-up.
