A method is described for shaping the bottom of hot-filled containers, in which the bottoms of the containers are forced inwardly from a state bulged outwardly, in particular as they cool down. Complex mechanisms for forcing the bottom inwardly are dispensable for the reason that the bottoms are forced inwardly by at least one fluid jet and/or fluid pressure wave. In addition, shaping the bottom can advantageously be carried out in a production region immediately downstream of a closer.

Method for shaping the bottom of hot-filled containers

A heating device for tempering preforms before processing in a stretch blow device. The heating device includes a heating alley with a plurality of infra red emitters, arranged parallel to the longitudinal axis of the tempered preforms. At least one back reflector and/or one filter is assigned to the infra red emitters, whereby the at least one back reflector and/or the at least one filter is segmented.

Heating device for the tempering of preforms

A heating device and a heating method for a blow molding machine comprise a heating element for radiating heat radiation for heating of preforms. A bottom reflector is movable relative to a counter reflector and is arranged opposite to the heating element for reflection of heat radiation radiated by the heating element in the direction of the preforms. A setting device is used for setting a position (L+BM, L+BM) of the bottom reflector relative to the counter reflector.

Heating device and heating method for blow molding machine as well as blow molding machine

A rotary-type furnace for conditioning preforms with a heating wheel at which several heating modules for heating one preform each are arranged, wherein the heating modules are each a heating chamber and a holding device for the preform. The furnace has a lifting device for lifting and lowering the holding device and/or the heating chamber to change between a loading or withdrawal position, in which the preform does not overlap with the heating chamber in the direction of its main axis, and a radiation position in which a section of the preform is arranged within the heating chamber, a particularly quick and reliable transfer from an infeed starwheel can be realized.
