A reel change device whereby a first strip, unwound off a runout reel, and a second strip, unwound off a new reel, are fed along an S-shaped path defined by two adjacent suction conveyor rollers with selectively-activated suction devices; the speed and timing of the strips are synchronized; the strips are then cut simultaneously along a first portion of the path, defined by the first roller, and are connected end-to-end as they travel at constant speed along a second portion of the path; and the cut-off portion of the second strip is fed by the first roller to a disposal container.
