Provided is a method for heating plastic preforms, wherein the plastic parison are transported along a predetermined transport path and are heated during this transport, wherein at least one first heating section with at least one first heating element as well as at least one second heating section with at least one second heating element is arranged along the transport path, by a first temperature measuring device an actual temperature of the plastic preforms is measured in or before a start region of the transport path, and as a function of this actual temperature of the plastic preforms the at least one first heating element is controlled in such a way that the plastic preforms reach a predetermined target temperature after heating by this at least one first heating element.

Method and apparatus for heating plastic preforms

A system for processing containers with a transport device which transports the containers along a predetermined transport path, wherein a plurality of holding devices for holding the containers is arranged on the transport device, wherein the system has at least one rotating device which rotates the plastic parisons with regard to a rotational position with respect to the longitudinal directions thereof. According to the invention the rotating device has an electrically operated driving device for producing the rotary movement of the plastic parisons with respect to the longitudinal directions thereof as well as at least one measuring device, which at least at times determines at least an electrical characteristic quantity of this driving device.

System and method for processing containers with monitoring of drive motors

Provided is an apparatus for expanding plastics material parisons into plastics material containers by a liquid medium with at least two transforming stations which fill and expand the plastics material parisons with the liquid medium with at least one common delivery device, which delivers the liquid medium to both transforming stations, wherein the transforming stations in each case have filling devices which fill the liquid medium into the plastics material parisons. According to the embodiments these transforming stations and/or filling devices in each case have a throttle device which are suitable and intended for changing the volume flow of the liquid entering the plastics material parisons.

Apparatus for transforming and filling plastics material containers with controlled filling

ABSTRACT The invention provides a method for leakage detection in a device for shaping container preforms, comprising a compressed air system which is connected to a compressed air source and comprises at least two fluidically connected regions that can be separated from each other and/or from the environment by shut-off elements. The method comprises a leakage test run conducted in an automated manner in which at least one of the blocking elements and/or the compressed air supply into the compressed air system is controlled in such a way that it can be determined separately for each region whether compressed air escapes therefrom.

Method for leakage detection in a device for shaping container preforms

Provided is an apparatus for heating plastic preforms, with a transport device which transports the plastic preforms along a predefined transport path, wherein this transport device has a plurality of holding elements for holding the plastic preform, and with at least one first heating section which is arranged along the transport path, and at least one second heating section which is arranged along the transport path downstream of the first heating section, wherein the heating sections each include a plurality of independently controllable heating elements which allow heating of the plastic preforms in several heating zones, lying above each other in the longitudinal direction of the plastic preforms, with a temperature profile which changes in the longitudinal direction of the plastic preforms, wherein the apparatus includes a control device for controlling these heating sections.

Apparatus and method for heating plastic preforms with controllable heating power

A machine for expanding plastic parisons into plastic containers by a liquid medium with at least two transforming stations. These transforming stations fill and expand the plastic parisons with the liquid medium, with at least one pressure generating device. This pressure generating device is suitable and intended to deliver the liquid medium to at least one filling device which fills the plastic parisons with the liquid medium, wherein at least one shut-off device is installed in at least one connection channel between the pressure generating device and the filling device, inside which the liquid medium is conveyed. This shut-off device is configured and provided in order that a fluid path inside the connection conduit can be at least partially interrupted.

Machine for expanding plastic containers with shut-off valve between pressure generating device and filling device

An apparatus is provided for producing plastic containers, comprising a heating device that heats plastic preforms, and including a shaping device provided downstream of this heating device in the transport direction of the plastic preforms, which shaping device shapes the plastic preforms into the plastic containers, wherein a tempering device for tempering the plastic preforms heated by the heating device is provided in the transport direction of the plastic preforms between the heating device and the shaping device, which tempering device has at least one tempering unit provided on a carrier rotatable about a predetermined rotary axis, and which tempering unit has at least two contacting devices, between which at least one section of the plastic preform can be received, which contacting devices can be moved in relation to one another along a predetermined direction.
