Abstract
An apparatus for heating plastic parisons includes a transport device which transports the plastic parisons along a predetermined transport path (T), and with at least one heating device, which is disposed stationary with respect to the transport path of the plastic parisons. The heating device has at least one first radiation source which emits thermal radiation as well as at least one reflector device which reflects at least a proportion of the thermal radiation emitted by the radiation source in the direction of the plastic parisons. The reflector device has a first section with a substantially parabolically curved configuration as well as a second section with a curved configuration, of which the curvature progression differs from the curvature progression of the first section.

An apparatus for heating plastic parisons comprising a transport device which transports the plastic parisons along a predetermined transport path (T), and at least one heating device, which is disposed stationary with respect to the transport path of the plastic parisons, wherein the heating device has at least one first radiation source which emits thermal radiation as well as at least one reflector device which reflects at least a proportion of the thermal radiation emitted by the radiation source in the direction of the plastic parisons, wherein the reflector device has a first section with a substantially parabolically curved configuration as well as a second section with a curved configuration, of which the curvature progression differs from the curvature progression of the first section.
A heating device for heating plastic parisons, wherein the heating device has at least one first radiation source which emits thermal radiation as well as at least one reflector device which reflects at least a proportion of the thermal radiation emitted by the first radiation source in the direction of the plastic parisons, and wherein the heating device has at least one second radiation source which is disposed offset with respect to the first radiation source, as well as a second reflector device which reflects at least a proportion of the thermal radiation emanating from the second reflector device in the direction of the plastic parisons, wherein the reflector device has a first section with a substantially parabolically curved configuration as well as a second section with a curved configuration, of which the curvature progression differs from the curvature progression of the first section.
A method for heating plastic parisons, wherein plastic parisons are transported by a transport device along a transport path and are heated by a heating device during this transport, wherein the heating device has at least one first radiation source which emits thermal radiation for heating the plastic parisons as well as at least one reflector device which reflects at least a proportion of the radiation emitted by the first radiation source onto the plastic parisons, wherein the reflector device reflects the thermal radiation of at least one first section with a substantially parabolically curved configuration, as well as a second section with a curved configuration, of which the curvature progression differs from the curvature progression of the first section, onto the plastic parisons.
