To provide for a horizontal offset (x) of the apex of a folding triangle former (2,42), the former triangle, together with a substrate removal or run-out roller (11,51) is movable in a plane positioned at the angle of inclination ( alpha ) of the folding former, for example by interengagement of projection-and-recess means formed on a frame (5,45) holding the former triangle in sidewalls (11,12;52,53) of the apparatus, the recess extending, for example in the form of an elongated slot, at the angle of inclination of the folding former.
