1. An apparatus for heating plastic preforms, said apparatus having a transport device which includes a circulating carrier configured to transport the plastic preforms along a predefined transport path, wherein the transport device comprises holding devices which are arranged on the circulating carrier, for holding the plastic preforms, wherein said transport path has at least one heating portion inside which the plastic preforms are heated with a heating device which is arranged stationarily at least in portions along the transport path and which heats the plastic preforms transported by the transport device during their transport through the heating portion, wherein the heating device has at least one stationary applicator device which is configured for bombarding the plastic preforms with microwaves in order to heat the plastic performs,
wherein
at least in the heating portion, the transport device is arranged relative to the applicator device such that at least parts of the holding devices are arranged outside the applicator device, wherein the applicator device is configured to receive several plastic preforms simultaneously for at least some of the time, and
wherein the applicator device is constructed as an element or unit having a slot through which the plastic preforms are transported, and the apparatus comprises a microwave generating device which is arranged outside the applicator device.
