An opening roller and a guiding surface are adapted for unfolding the conveyor belt by means of separating the first and second segments. A spreader roll is adapted to keep the conveyor belt unfolded while a tail of said web material is placed on said first segment. A folding roll is adapted for folding said second segment over said first segment for to enclose the tail in the conveyor belt. The spreader roll comprises a first roll portion, a second roll portion and a circumferential guiding track separating the roll portions. The first roll portion, which is adapted for supporting said first segment, has a cylindrical outer surface.
