Abstract

The invention relates to a method of a set change in a slitter-winder, in which method a set change is performed in a winder (10) of the slitter-winder by a set change system (10), which winder (10) is a two-drum winder and comprises two winding drums (11, 12), of which winding drums (11, 12) at least one is movable to adjust distance between the winding drums (11, 12), and a rider roll unit (20), in which winder customer rolls (15) are wound on support of the winding drums (11, 12) of partial webs of a slitted fiber web, which set change system (40) comprises an adhesive application device (23), a cutting device (22), roll pusher (21) and a core placer (24), which method is performed to remove a set of complete customer rolls (15) from the winder and to provide new cores for winding next set of customer rolls (15), in which method the adhesive application device (23) applies adhesive on partial webs running towards the customer rolls (15) and when the adhesive has reached surface of the customer rolls (15), the partial webs are cut by the cutting device (22), set of the completed customer rolls (15) are removed by the roll pusher (21) and new cores are set on support of the winding drums (11, 12) by the core placer to begin winding of next set of the customer rolls (15), wherein when the set of the complete customer rolls (15) have been removed, the winding drums (11, 12) are moved back towards their position for beginning of the winding and the new cores (14) are set by the core placer (24) on support of the winding drums (11, 12) from above simultaneously, when the roll pusher (21) reaches its turning point between its pushing movement and its return movement back to its rest position. In the method simultaneously with the movement of the roll pusher (21) back to its rest position the rider roll unit (20) is moved downwards towards its position at beginning of the winding of the next set of customer rolls (15) The invention also relates to a slitter-winder comprising a set change system (40).
