Abstract
An apparatus for heating plastic preforms includes a first transport device that transports the plastic preforms in a separated manner, wherein said first transport device has a plurality of recesses for receiving the plastic preforms, and a second transport device that takes over the plastic preforms transported by the first transport device and transports the plastic preforms along a predetermined transport path. The apparatus has at least one sensor device that detects at least one measured value that is characteristic of at least one of the two drive devices, and a control device that is designed to control the drive device for moving the holding elements as a function of this characteristic measured value.

An apparatus for heating plastic preforms, comprising a first transport device that transports the plastic preforms in a separated manner, wherein said first transport device has a plurality of recesses for receiving the plastic preforms, comprising a second transport device that takes over the plastic preforms transported by the first transport device and transports said plastic preforms along a predetermined transport path, wherein the second transport device has a plurality of holding elements for holding the plastic preforms and at least one heating device that heats the plastic preforms transported by the second transport device, wherein at least the first transport device is a circulating transport device, wherein the apparatus comprises a drive device for moving the holding elements in a longitudinal direction of the plastic preforms, and the apparatus has at least one drive device for driving at least one transport device,
- wherein
- the apparatus has at least one sensor device adapted to detect at least one measured value that is characteristic of at least one of the two drive devices, and a control device adapted for controlling the drive device for moving the holding elements as a function of this characteristic measured value.
A method for heating plastic preforms, wherein the plastic preforms are transported in a recess of a first transport device and are taken over by a second transport device in a predetermined take-over position and are transported by said second transport device by holding elements that hold the plastic preforms along a predetermined transport path, and are heated, at least temporally, during the transport along the transport path by at least one heating device,
- wherein
- at least one drive device drives at least one transport device and the holding elements are moved in the longitudinal direction of the plastic preforms by a further drive device,
- wherein
- at least one measured value that is characteristic of at least the drive device is detected and the further drive device is controlled as a function of this measured value.
