ABSTRACT:
A winder for winding a running web of paper, foil or similar. A support drum of web width is provided, and a winding drum on which the web is wound to a roll. A pair of primary swivel levers each feature on one end a fork for receiving a winding drum bearing and is mounted with its other end in the region of the support roll axis in such a way that the winding drum, in swiveling from a first position above the support roll, will in the running direction of the web approach the support roll while moving around it, passing in the process a primary section until reaching a second position. The winding drum with the still unfinished paper roll is taken over by a pair of secondary swivel levers with an essentially horizontal guideway extending from the second position across a secondary section up to a third position. A contact device forces the winding drum onto the support roll, and a drive is coordinated with the winding drum. A slide features guideways for guidance of the drive as it passes through the primary section, and is connected with the primary levers in such a way that it also will perform their swivel movement. A connecting link guide adjusts the radial position of the slide according to the current paper roll diameter, and ensures the slide tracking according to the increase in paper roll diameter. A guide rod clutch is arranged between the drive and the winding drum.
