Provided is an apparatus for heating plastic parisons, including a transport device or transporter, which transports the plastic parisons at least in sections along a predefined transport path, wherein the transport device or transporter has a plurality of holding devices or holders for holding the plastic parisons, with a heating device or heaters for heating the plastic parisons at least at times, while they are being transported by the transport device or transporters, wherein the apparatus has at least one heat shielding device or heat shield which is suitable and intended to counteract the heating of mouth regions of the plastic parisons.
An apparatus for heating plastic parisons, comprising a transporter, which transports the plastic parisons at least at sections along a predefined transport path, wherein the transporter has a plurality of holders for holding the plastic parisons, with a heater for heating the plastic parisons at least at times, while they are being transported by the transporter, wherein the apparatus has at least one heat shield which is suitable and intended to counteract the heating of mouth regions of the plastic parisons, wherein the at least one heat shielding devices has at least one first heat shielding element and a second heat shielding element which can be moved relative to one another and which, in at least one relative position with respect to one another, at least partially surround a portion of a plastic parison in the circumferential direction thereof.
A shielding element for shielding heat from plastic parisons which are being transported upright, with a holder in order to fasten the shield at least indirectly to a transporter for transporting plastic parisons, with a first recess which is suitable and intended to receive at least a portion of a first plastic parison, wherein this recess extends over a circumferential angle of less than 180°, wherein the shield has a second recess which is suitable and intended to receive at least a portion of a second plastic parison, wherein this second recess extends over a circumferential angle of less than 180°.
A method for heating plastic parisons wherein the plastic parisons are transported by a transporter along a predetermined transport path and are heated at least at times during this transport, wherein a heating of mouth regions of the plastic parisons is counteracted by a heat heat shield, wherein the heat shield in each case have a first heat shielding element and a second heat shielding element which can be moved relative to one another and which, in at least one relative position with respect to one another, at least partially surround a portion of the plastic parison in the circumferential direction thereof.
