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.
