Abstract

A reel apparatus for reeling a traveling web produced on a papermaking machine comprises a rotatable support drum which is fixedly mounted in a frame. A pair of parallel, horizontally disposed rails are mounted to the frame with the tops of the rails above the apex of the support drum. New reel spools are brought into supporting engagement on the rails at a location downstream of the apex of the support drum and intermediate the apex of the support drum and a jumbo-sized wound web roll which is being wound while being powered by a centerwind assist drive, as well as nipping engagement with the support drum. Each reel spool is supported in a pair of carriages which are mounted to travel over the rails. Hydraulic cylinders selectively move each pair of carriages reciprocally along the rails between a new-reel- spool-receiving, or ready, position, a reeling position where the reel spool/newly-started- wound-web roll is nipped against the support drum, a downstream position where the wound paper web roll is disengaged from its nip with the support drum, and an ejection position where the wound web roll is moved against stops at the far end of the rails away from the support drum.

Claims11

Dependent claims

Apparatus for reeling a traveling paper web into a wound web roll on a reel spool having a journal at either end thereof, the apparatus having front and back sides and comprising, in combination:

a frame;
a support drum, having an axis of revolution, rotatably mounted to the frame in a fixed position with its axis of revolution horizontally disposed;
support drum drive means operatively linked with the support drum for rotatably driving the support drum;
a pair of parallel, substantially horizontally disposed rails mounted to the frame with the top surfaces of the rails located above the apex of the support drum surface with one rail mounted at each of the front and back sides of the apparatus, the rails extending from spool-supporting proximity of the reel spool with the support drum surface downstream in the direction of travel of the on-coming web;
carriage guide means operatively associated with each of the rails for supporting carriages for longitudinal movement parallel with each of the rails;
a pair of cooperating carriages, each of said carriages mounted on a carriage guide means associated with a corresponding rail, each carriage initially selectively positionable for receiving a new reel spool in a ready position downstream in spaced adjacency relative to the support drum and for being subsequently positionable upstream of the ready position and into nipping engagement with the support drum for receiving the traveling web to be wound into a wound web roll thereon, the ready position being downstream of the apex of the support drum surface;
centerwind drive means for selectively engaging and rotatably driving the said new reel spool when the said new reel spool is supportingly mounted in the said pair of carriages;
position means for selectively 1) positioning the said pair of carriages into the said ready position relative to the support drum to receive a new reel spool for reeling the traveling web onto the said new reel spool, the said ready position being downstream of the apex of the support drum, 2) positioning the said pair of carriages supporting the new reel spool into a reeling position where it is downstream of the apex of the support drum surface and in nipping engagement with the support drum for reeling the traveling web into a wound web roll thereon, and 3) controllably positioning the said pair of carriages downstream to control the nip pressure between the web roll being wound and the support drum during the reeling of the wound web roll, and to move the wound web roll from nipping engagement with the support drum, as desired;
whereby the wound web roll is moved downstream while being horizontally supported, rotatably driven, and in controlled nipping engagement with the support drum, continuously until the desired diameter wound web roll is reached.

6 more elements

A method for reeling a traveling paper web into a wound web roll on a reel spool having a journal at either end thereof, the method utilizing a support drum for nipping engagement with the web roll and a new reel spool, comprising the steps of:

supporting a new reel spool in a ready position for rotation, and for translational movement substantially horizontally, the ready position being downstream of the apex of the support drum surface such that the new reel spool is in spaced adjacency with the support drum;
engaging the support drum with a drive means for rotatably driving the support drum;
selectively engaging a journal at one end of the new reel spool in the ready position with a centerwind drive means for rotatably driving the new reel spool and bringing it up to a desired speed;
positioning the new reel spool into a reeling position in nipping engagement with the rotatable support drum, which support drum is fixedly mounted in a frame to rotate about a horizontally disposed axis of rotation thereof, the reeling position also being downstream of the apex of the support drum surface relative to the direction of the traveling web;
directing the on-coming traveling web into the nip between the new reel spool and the support drum;
reeling the traveling web onto the new reel spool to begin the formation of a wound web roll thereon;
maintaining horizontal support of the wound web roll as its increasing diameter allows the wound web roll to move translationally downstream of the support drum:
selectively maintaining controlled nip pressure between the paper web roll being wound and the support drum;
maintaining rotational drive of the new reel spool of the web roll as it is wound to desired wound web roll diameter;
supporting another new reel spool in the ready position for rotation, and for translational movement substantially horizontally, while maintaining nipping engagement between the web roll being wound and the support drum, the said another new reel spool being in spaced adjacency with both the support drum and the web roll being wound while in the ready position;
selectively engaging a journal at an alternate end of the said another new reel spool, relative to the end of the preceding said new reel spool engaged by a centerwind assist drive means, with another centerwind drive means for rotatably driving the said another new reel spool and bringing it up to a desired speed;
removing the wound web roll from nipping engagement with the support drum when the wound web roll has reached a desired diameter;
positioning the said another new reel spool in a reeling position in nipping engagement with the support drum;
severing the traveling paper web from the web roll being wound to produce a finished wound web roll;
transferring the traveling paper web onto the said another new reel spool;
removing the finished wound web roll from its horizontal support while the traveling web is reeled onto the said another new reel spool.
