Claim:
1. An apparatus for treating plastic preforms, with a first transport facility transporting the plastic preforms along a predefined transport path at a first predefined pitch, with at least one heating means heating the plastic preforms at least at times during their transportation and with a second transport facility arranged downstream with respect to the first transport facility in transport direction of the plastic preforms, the second transport facility comprising a plurality of holding means for holding the plastic preforms and which is constructed and arranged to alter a pitch between consecutive plastic preforms, wherein the apparatus comprises, a further transport facility arranged in the transport direction of the plastic preforms between the first transport facility and the second transport facility, in which a pitch between the plastic preforms is altered; wherein the first transport facility comprises a circulating transport means, on which a plurality of different holding means for holding the plastic preforms is arranged, and wherein: the pitch is altered in two parts to counteract excessive pitching speeds or accelerations which act upon the plastic preforms, the two parts including the further transport facility that alters the pitch and the second transport facility that further alters the pitch.
