An apparatus and method for engaging a reel spool with a Pope reel on a web winding machine. Primary forks lower a new reel spool into nip contact with the Pope reel. After being brought into nip contact, the reel spool is supported by the Pope reel and support plates mounted on the primary forks. As the primary forks continue to lower the reel spool, the contact area between the supporting plates and reel spool changes so as to maintain a substantially constant pressure between the reel spool and Pope reel. The primary forks lower and transfer the reel spool onto reel tracks. The primary forks are then repositioned to receive the next reel spool.

Method and apparatus for winding a web

The present invention relates to an apparatus for decelerating the jumbo roll of a paper or a board manufacturing machine in order to minimize the time required for a reel drum exchange and the amount of paper or board wasted as the jumbo roll slackens. The apparatus comprises brake shoes (9, 11) and arms (8) provided with means (13) producing the decelerating force. The arms can simultaneously transfer and decelerate the jumbo roll (2) whereby also a loop in the web is formed rapidly and easily.

Method and apparatus for decelerating a jumbo roll of a paper or board

A method and apparatus for on-machine winding of a web, including a Pope reeling drum (10) and a reel spool (11). The web (W) to be wound passes over the drum. An empty reel spool (11') is brought into the grip of primary arms in such a way that bearing members (25) of the reel spool (11') are supported by guiding elements located at both sides of the drum (10) in such a manner that the reel spool (11') is not engaged with the drum (10). The empty reel spool (11'), preaccelerated to winding speed, is then brought into nip contact with the rotating reel drum (10), by moving the spool into recesses (21) in the guiding plates thereby forming a nip (10) through which the web (W) passes. The web breaks off and begins to wind onto the empty reel spool (11).

A method of charging reel drums (4) of a paper or a board manufacturing machine winder to the front end of a store (12) disposed on top of the winder; and of lowering the reel drums (4) from the store (12). During the charge of the reel drums (4) to the store, the reel drums (4) already in the store (12) are pushed from the front end (13), i.e. loading and discharge end of the store towards the rear end at least by a distance (D) equal to the diameter of the reel drum (4). When a reel drum (15) is lowered, the drums (4) which are in the store displaced at a distance equal to the reel drum diameter from the front end (13) of the store (12), are kept in place.

Apparatus for transferring reel drums to the winder of a paper or board

A web of a paper or board manufacturing machine is severed utilizing a severing tape in a fully automatic operation. A main (Pope) cylinder and reel drum are part of a winder for the web, and have a nip therebetween, the cylinder and drum mounted for rotation about parallel axes. A severing tape is attached by adhesive tape to a cardboard card mounted by a pivotal arm on a first side of the winder, with an intermediate portion of the tape held outwardly from the arm by a tape dispenser with spring clip. On the second side of the winder a swing guide is mounted for pivotal movement about an axis perpendicular to the main cylinder, and mounts a spool of tape for rotation about an axis parallel to the main cylinder. The card is inserted in the nip when web severing is desired, tape is taken up on the reel drum, and after the tape is tensioned and severs the web the tape is cut by a pair of cutting blades mounted at the second side of the winder. The operation may then be repeated for another web after attaching the severed end of the tape to another card.

Apparatus for severing a web

A method and an apparatus for winding of webs of paper, board and the like on cores wherein the wound web roll is supported on two parallel supporting drums. A new core is brought into the space formed by the wound web roll and the supporting drums. The web is fastened to the new core by fasteners such as nails or staples and severed while the wound web roll is being supported by the supporting drum adjacent to the supporting drum on the infeed side of the apparatus and the web is running over the periphery of the new core.
