Abstract
An apparatus for reshaping plastic preforms into plastic containers includes a plurality of blow-molding stations that each have at least one receptacle space, within which the plastic preforms can be expanded into the plastic containers. The apparatus also includes a conveying device that conveys the containers along at least one specified travel path, wherein the apparatus has a plurality of heating devices that are arranged along the travel path of each container, upstream of the blow-molding stations, wherein at least one heating device is allocated to at least one blow-molding station.
Claims22
Apparatus for reshaping plastic preforms into plastic containers, comprising:
- a plurality of shaping stations each having at least one receiving chamber within which the plastic preforms can be expanded to produce the plastic containers;
- a transport device which transports the plastic preforms along at least one predetermined transport path;
- and
- a plurality of heating devices which are disposed along the at least one predetermined transport path upstream of the shaping stations;
- at least one heating path for transporting the plastic preforms through the heating device, wherein the at least one heating path is distinct from the transport device,
- wherein a first heating device in the plurality of heating devices is associated with a first shaping station in the shaping stations, the first heating device operating at a first temperature,
- wherein a second heating device in the plurality of heating devices is associated with a second shaping station in the shaping stations, the second heating device operating at a second temperature which can be distinct from the first temperature,
- wherein a coordination between the plurality of heating devices and the shaping stations is established,
- wherein the coordination between the plurality of heating devices and the shaping stations enables individual treatment of different plastic preforms at different temperatures.
