A storage arrangement for empty cores for a reel-up in which paper is wound to form reels of paper, said storage arrangement having a stand comprising a feed-out ramp and a container with a top, a bottom and four vertical sides consisting of a front side facing the feed-out ramp, a rear side and two sides, said four sides between them defining a space for empty cores, which container also comprises an upper inlet opening and a lower outlet opening in conjunction with the upstream end of the feed-out ramp. According to the invention a plurality of downwardly inclined planes are arranged one beneath the other inside the container, directed alternately from the front side and the rear side, each plane having a downstream end located a predetermined distance from the adjacent rear side or front side to provide an opening therebetween so that each empty core rolling down an upstream plane continues freely to the next plane in a continuous path from the inlet opening to the outlet opening. The stand also includes a stand table, at which the container is exchangeably arranged in conjunction with the feed-out ramp to enable transport of the container to a filling station.

Storage arrangement for cores of a papermaking machine

A reel-up for reeling a paper web onto reeling drums (2), comprising stand parts (5) with rails (9), along which the reeling drums (2), rotatably carried by their bearing housings (4), are displaced, a surface winding drum, over which the paper web runs and which is rotatably journalled in bearing housings (13) on the stand parts, a secondary system, and a primary system, having primary arms (24) with gripping members (33) for retaining a reeling drum (2), which primary arms have actuators (28) for moving the reeling drum (2) along the envelope surface of the surface winding drum. Each primary gripping member has outer and inner locking arms (34, 35), pivotably journalled about a common journalling shaft (36) on the primary arm, a first actuator (44), carried by the gripping member to open and close the same by pivoting the outer locking arm (34) about the journalling shaft (36) in relation to the inner locking arm so as, in the open position, to receive the reeling drum and, in the closed position, retain the same in its bearing housings (4), and a second actuator (45), mounted between the primary arm and the inner locking arm (35). The outer and inner locking arms and the first actuator constitute a pivotable unit for regulating the linear load.

Reel-up and method of controlling nip load therein

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.

Reel-up

A reel-up in a paper machine in which the web is reeled onto reeling drums provided with cores, the reel-up having an upper pair of parallel rails extending from the downstream end of the reel-up to its upstream end to support a stock of reeling drums provided with cores, and a handling station for handling finished reels of paper, reeling drums and cores, the handling station having a vertically movable lifting table for receipt of a finished reel of paper, a device for moving a reeling drum out from a reel of paper on the lifting table and for subsequently inserting the reeling drum into at least one core on the lifting table, and a device for feeding cores out onto the lifting table. According to the invention the handling station is provided with a lifting device comprising two lifting elements arranged to be brought into engagement with a reeling drum provided with core(s) and situated on the lifting table, and to lift this and deliver it to the upper pair of rails. Actuators are connected to the lifting elements to move them from the lifting table to the delivery point at the upper pair of rails.

Reel-up and multi-functional handling device therefor

An apparatus for removing dust released, for instance, during the production of a soft crepe paper web which is creped off a Yankee cylinder and spread laterally. The apparatus comprises a dust suction box consisting of a housing with an inner suction chamber, said housing having a first inlet in the form of a suction gap, a main part and first and second parts which define said suction gap between them. According to the invention the main part is in the form of part of a cylinder to provide a corresponding curved inner side in the suction chamber, and the suction gap comprises an outer gradual throttling and an inner gradual enlargement, said throttling and enlargement merging at a transition where said throttling is maximal. The first inlet forming part preferably comprises a flat surface that defines its side of said enlargement whereas the second part forming the inlet comprises both a curved surface having a predetermined radius and such an arc length that it defines the whole of its side of the throttling and an initial part of the enlargement, and also an inner, flat surface extending at a tangent from the curved surface and forming an acute angle .alpha. with a tangent to the curved surface at said transition.

Dust removal apparatus

A reel-up in which paper is reeled up on reeling drums to form paper reels, said reel-up comprising two stand members each having a stand rail to support the reeling drum; a surface winding mechanism over which the web runs; and a secondary system with at least one secondary unit for receipt of a reeling drum, wherein the secondary unit comprises first and second secondary bodies which are linearly movably journalled in said stand members. According to the invention each secondary body comprises a lifting mechanism for lifting the reeling drum from the stand rail to a production level in which the reeling drum is free from the stand rails and the load of the paper reel and the reeling drum is taken up by the secondary bodies and transferred to the stand members. The lifting mechanism comprises a top rail with an upper support surface parallel to the adjacent stand rail, and at least one actuator to bring the support surface of the top rail into contact with the reeling drum and effect the lifting through vertical movement of the top rail.

A reel-up in which paper is reeled up on reeling drums to form paper reels, said reel-up having two parallel stand members; a surface winding mechanism in the form of a rotating surface winding drum and/or a belt to carry the web and deliver it to one of said reeling drums or a paper reel formed or being formed thereon; and a secondary system including first and second secondary units for alternate receipt of new reeling drums. Each secondary unit, includes an outer first secondary member and an inner second secondary member, each of the secondary members having a linearly movable secondary body, an actuator for moving the secondary body, and a press device to maintain a predetermined linear pressure in the nip between the surface winding means and the paper reel as it increases in size. Each secondary body includes a bottom plate and a pivot unit pivotably journalled in a journalling element for turning between a position folded up from the bottom plate for collection of an empty reeling drum and a production position folded down to the bottom plate for reeling the web.
