A sheet (not shown) fed by belt 1 is laterally registerable against a side lay 5b, the transverse position of which is adjustable, eg to position 5b', and over the whole extent of adjustability, a belt 7 provides part of and/or an extension to the surface(s) supporting the sheet. Sheet supporting surfaces (2a and 2b, figure 1) are separated by a gap, along the length of which the lay is adjustable, and the gap is covered by the belt 7, both to the right and left of the lay. <IMAGE> |
