At least two flexible belts each having a pair of longitudinal edges are fed parallel to each other to a uniting station with one edge of one unfinished belt transversely confronting one edge of the other unfinished belt. The two unfinished belts are laterally separated at the station so that their one edges are spaced from and parallel to each other and a separator belt is inserted into a space defined between the one edges. Then the two unfinished belts and the separator belt are fed together into a press, and are there hot pressed.
