A method for controlling paper web reel-up, particularly in a Pope-type reel-up apparatus, wherein a reeling cylinder provides power to a paper web reel being formed on a reeling drum at a nip formed between the periphery of the reeling cylinder and the periphery of the web reel being formed. The reeling operation is begun with the reeling drum held in primary forks. The reeling drum and inner section of the web reel formed on it are removed from the primary forks and delivered to secondary forks in which the final steps of the reeling operation are carried out. The primary and secondary forks are coupled to power equipment by which the loading of the power-transmitting nip is generated. In accordance with the invention, the nip loading force provided by the power equipment during the reeling operation is adjusted by control signals determined by the position of the primary and secondary forks in a manner such that a substantially even load distribution will occur even in the exchange step in which the reeling drum and web reel being formed on it are moved from the support of the primary forks to the support of the secondary forks.
A method for controlling a paper web reeling operation in reeling apparatus including a reeling drum around which a paper web reel is wound and a reeling cylinder for transmitting power required for reeling to the paper web reel mainly through a nip formed between the periphery of said reeling cylinder and the periphery of the paper web reel being formed, and wherein the reeling operation is begun with said reeling drum supported in primary forks from which said reeling drum and an inner section of the paper web reel wound therearound are transferred to secondary forks in which the reeling operation is completed, and wherein power equipment is coupled to said primary and secondary forks for loading the nip between said reeling cylinder and the paper web reel, comprising the steps of:
