Abstract:
1. A method for blow molding containers, in which a preform made of a thermoplastic material is subjected to thermal conditioning along a conveyance path in a heating line and then molded into a container in a blow mold by the action of blowing pressure, and in which the thermal conditioning is carried out by several radiant heaters arranged one above the other, which are activated by a control unit that presets at least one heating profile, wherein the radiant heaters ( 41 ) are activated according to a first heating profile during a production operation and according to a second heating profile that is different from the first heating profile during a standby operation, wherein during the standby operation no preforms in the region of the heating line are heated and no preforms are introduced into the heating line, the second heating profile providing a different distribution of heating power in the region of the heating line compared to the first heating profile.
