Abstract

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.

Claims22

Dependent claims

A reel-up in a paper machine in which paper is produced in a continuous web and reeled up on reeling drums to form paper reels, said reel-up comprising:

two elongate parallel stand members each having an upstream end and a downstream end;
a moving winding surface arranged at the upstream end of the stand members to carry the web and deliver the web to a reeling drum;
a primary device for moving empty reeling drums to a position adjacent to the parallel stand members to commence a reeling operation;
and
first and second pairs of secondary members for alternate receipt of each empty reeling drum, one secondary member of each of said pairs being arranged between said stand members and the other secondary member of the respective pair being arranged outside of said stand members, each of said secondary members comprising;
a support member adjacent to a respective stand member,
a linear actuator for linearly moving the support member in a direction parallel to the stand member,
a press device pivotally supported on said support member for engaging an end of an empty reeling drum and pressing the reeling drum against the winding surface so that a predetermined linear nip pressure is maintained as the paper reel increases in size, and
an actuator for pivoting the press device between a collection position folded away from the support member for collection of an empty reeling drum and a production position folded towards the support member for reeling the web onto the collected reeling drum.

6 more elements

A secondary system for a reel-up of a paper machine having a moving winding surface for carrying and delivering the web, said secondary system comprising:

a first pair of secondary members for receipt of an empty reeling drum, each of said secondary members comprising;
a support member,
a linear actuator for linearly moving the support member in a direction towards the winding surface,
a press device pivotally supported on said support member for engaging an end of an empty reeling drum and pressing the reeling drum against the winding surface so that a predetermined linear nip pressure is maintained as the paper reel increases in size, and
an actuator for pivoting the press device between a collection position folded away from the support member for collection of an empty reeling drum and a production position folded towards the support member for reeling the web onto the collected reeling drum, and
a second pair of secondary members for alternate receipt of an empty reeling drum, each of said secondary members comprising;
a support member,
a linear actuator for linearly moving the support member in a direction towards the winding surface,
a press device pivotally supported on said support member for engaging an end of an empty reeling drum and pressing the reeling drum against the winding surface so that a predetermined linear nip pressure is maintained as the paper reel increases in size, and
an actuator for pivoting the press device between a collection position folded away from the support member for collection of an empty reeling drum and a production position folded towards the support member for reeling the web onto the collected reeling drum.
