A method for effecting a set change in a winder (14) for a papermaking machine, comprises skip-slitting the paper web (W) across the width of the web (W) transversely to the direction of web travel in the winder (14). An adhesive stripe (44, 44') is appli- ed to the web (W) on either side of where the skip-slit (50) is located. The skip-slit (50) and application of the glue is done at a location upstream of the winder (14) to avoid the problems associated with mounting and operating such equipment beneath the winder (14). The paper web (W) is severed by advancing the skip-slit (50) to a position near the 10 o'clock position over the sur- face of a first winder drum (12) where the web (W) is halted and the wound paper roll (R) is urged off its support on the first win- der drum (12) to thereby increase the tension in the web between the wound roll (R) and web (W) supported on the first winder drum (12) to sever the web. The adhesive stripes (44, 44') on either side of the severance are then applied to the wound roll (R) and a new core, and the process is repeated.
