Multi-reel apparatus in a paper machine
First Claim
1. A multi-reel apparatus for winding a continuous travelling web onto each of a plurality of cores to form a plurality of rolls in a web manufacturing machine, comprising:
- a web support that supports said travelling web along a path of travel that extends from a first vertical level to a second vertical level spaced vertically from the first vertical level;
vertically stacked first and second reeling stations located respectively at the first and second vertical levels, each reeling station having at least one reeling device operable to hold and rotatably drive a core onto which the web is wound to form a roll, and being further operable to move the core into engagement with the web on the web support to initiate reeling of the web onto the core, and to move the core away from the web support when the roll is fully wound so that the web can begin reeling onto the core held in another reeling device.

Abstract
A multi-reel apparatus for use in a drying section of a papermaking machine allows a web to be continuously wound without interruption. The apparatus includes a web support and a pair of vertically stacked reeling stations located along an inclined portion of the web support. Each reeling station has at least one reeling device operable to hold and rotatably drive a core onto which the web can wound to form a roll. Each reeling device is further operable to move the core into engagement with the web on the web support to initiate winding of the web onto the core, and to move the core away from the web support when the roll is fully wound. Winding is alternated between reeling devices, allowing the completed roll to be removed and a new core to be loaded at one reeling station while the other reeling station continues in full winding operation.

34. A method for winding a continuous travelling web sequentially onto each of a plurality of cores to form a plurality of rolls in a web manufacturing machine, comprising the steps of:
-
advancing the web, supported on a web support, along a path of travel that passes adjacent to a first reeling station at a first vertical level and a second reeling station at a second vertical level;
holding and rotatably driving a core with a reeling device in each of the reeling stations;
moving the core held by the reeling device at the first reeling station into engagement with the web being directed by the web support;
winding the web onto the core held by the reeling device at the first reeling station and thereby forming a completed roll;
moving the core and completed roll away from the web support and out of engagement with the web with the reeling device at the first reeling station;
winding the web onto the core held by the reeling device at the second reeling station; and
alternating between winding in the first and second reeling stations so that the web is continuously wound. - View Dependent Claims (35, 36, 37, 38, 39, 40, 41, 42)

43. A method for winding a continuous travelling web onto each of a plurality of cores to form a plurality of small rolls in a web manufacturing machine, comprising the steps of:
-
dividing the web into a pair of partial-width web portions;
advancing the web portions, supported on a web support, along a path of travel that passes adjacent to a first reeling station at a first vertical level and a second reeling station at a second vertical level vertically spaced from the first vertical level;
holding and rotatably driving a pair of cores with a pair of adjacent reeling devices in each of the reeling stations;
moving the cores held by the reeling devices at the first reeling station into engagement with the two web portions on the web support;
winding each web portion onto a respective one of the cores held by the reeling device at the first reeling station and thereby forming a pair of completed small rolls;
moving the cores and completed small rolls away from the web support and out of engagement with the web with the pair of reeling devices at the first reeling station;
winding the web onto the cores held by the reeling devices at the second reeling station; and
alternating between winding in the first and second reeling stations so that the web is continuously wound.

44. A method for winding a continuous travelling web onto each of a plurality of cores to form a plurality of small rolls in a web manufacturing machine, comprising the steps of:
-
dividing the web into first and second partial-width web portions;
advancing the first web portion, supported on a web support, along a path of travel that passes adjacent to a first reeling station at a first vertical level and advancing the second web portion, supported on the web support, along a path of travel that passes adjacent to a second reeling station at a second vertical level vertically spaced from the first vertical level; and
simultaneously winding the first web portion in the first reeling station and the second web portion in the second reeling station. - View Dependent Claims (45, 46)
holding and rotatably driving a pair of cores with a pair of reeling devices vertically stacked in each of the reeling stations; and
alternately winding the first web portion first in one then in the other of the reeling devices of the first reeling station, and alternately winding the second web portion first in one then in the other of the reeling devices of the second reeling station.
