To attach the free toothed-belt ends (10, 11) to the guide block (26) the former are each passed over a part of a toothed wheel, in particular a toothed half-wheel (toothed half-wheel roller 20, 21), fixed to the guide block (26), while the complementary toothed systems of toothed belt and toothed wheel or toothed roller engage positively.
