ABSTRACT:
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.
