Abstract
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.
Claims20
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 defining an outer side opposite the other stand member, each of said stand members further 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 alternately receiving each empty reeling drum and engaging the reeling drum against the winding surface to wind the web onto the reeling drum, each of said pairs comprising;
- a linearly movable first secondary member supported at the outer side of one of the stand members for supporting and enabling linear movement of one end of the reeling drum along a respective stand member,
- a linearly movable second secondary member supported at the outer side of the other stand member for supporting and enabling linear movement of the other end of the reeling drum along a respective stand member such that the reeling drum is moved by a pair of secondary members which are both arranged outside of the stand members, and
- wherein the first and second pairs of secondary members are positioned and arranged not to interfere with each other as the pairs of secondary members alternatively receive and engage the reeling drums against the winding surface.
A stand arrangement for a reel-up in a paper machine in which paper is produced in a continuous web and reeled up on reeling drums by a winding surface to form paper reels, said reel-up comprising:
- two elongate parallel stand members, each defining an outer side opposite the other stand member, each of said stand members further having an upstream end and a downstream end;
- and
- first and second pair of secondary members for alternately receiving each empty reeling drum and engaging the reeling drum against the winding surface to wind the web onto the reeling drum, each of said pairs comprising;
- a linearly movable first secondary member supported at the outer side of one of the stand members for supporting and enabling linear movement of one end of the reeling drum along a respective stand member,
- a linearly movable second secondary member supported at the outer side of the other stand member for supporting and enabling linear movement of the other end of the reeling drum along a respective stand member such that the reeling drum is moved by a pair of secondary members which are both arranged outside of the stand members, and
- wherein the first and second pairs of secondary members are positioned and arranged not to interfere with each other as the pairs of secondary members alternately receive and engage the reeling drums against the winding surface.
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:

- and
- first and second pairs of secondary members for alternately receiving each empty reeling drum and engaging the reeling drum against the winding surface to wind the web onto the reeling drum, each of said pairs comprising;
- a linearly movable first secondary member for linear movement of one end of the reeling drum, said first secondary member having,
- a support member for supporting the first secondary member at the outer side of the 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 the support member for engaging the end of the reeling drum, and
- an actuator for pivoting the press device between a collection position folded away from the support member and a production position where the press device is folded towards the support member, and
- a linearly movable second secondary member for linear movement of the other end of the reeling drum, said second secondary member having,
- a support member for supporting the second secondary member at the outer side of the 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 the support member for engaging the end of the reeling drum,
- an actuator for pivoting the press device between a collection position folded away from the support member and a production position where the press device is folded towards the support member, and
- wherein the first and second pairs of secondary members are positioned and arranged not to interfere with each other as the pairs of secondary members alternately receive and engage the reeling drums against the winding surface.
