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.

Reel-up and associated method

A reel-up in which paper is reeled up on reeling drums to form paper reels is provided. The reel-up comprises two stand members provided with stand rails to support the reeling drum. A secondary system consisting of first and second secondary units for receipt of new reeling drums is provided adjacent to the stand members. Each secondary unit comprises a first and a second secondary member, each arranged adjacent one of the stand members. Both secondary members of each secondary unit are arranged at the outer sides of the stand members so that the deleterious effects of paper dust, etc. between the stand members are eliminated.

Reel-up

A reel-up in which paper is reeled up on reeling drums to form paper reels, said reel-up having two parallel stand members; a surface winding mechanism in the form of a rotating surface winding drum and/or a belt to carry the web and deliver it to one of said reeling drums or a paper reel formed or being formed thereon; and a secondary system including first and second secondary units for alternate receipt of new reeling drums. Each secondary unit, includes an outer first secondary member and an inner second secondary member, each of the secondary members having a linearly movable secondary body, an actuator for moving the secondary body, and a press device to maintain a predetermined linear pressure in the nip between the surface winding means and the paper reel as it increases in size. Each secondary body includes a bottom plate and a pivot unit pivotably journalled in a journalling element for turning between a position folded up from the bottom plate for collection of an empty reeling drum and a production position folded down to the bottom plate for reeling the web.
