A heater of preforms comprises a heating chamber, loading and unloading areas and a closed movable loop. The movable loop is made at least in the form of two superposed disks with radial grooves for preforms, above each disk in a circle retaining guides for preforms are located, and under each disk from both sides of preforms heaters are placed in a circle. Such design implementation of the device allows to simplify its design, to reduce the size and to eliminate the dynamic load on the elements of the device and thus improve its reliability and performance. |
