Claim 0:
1. An apparatus for forming plastic material preforms into plastic material containers, said apparatus having a transport device configured to transport the plastic material preforms along a predetermined transport path, wherein this transport device comprises a plurality of transport devices for transporting the plastic material preforms, a heating device configured to heat the plastic material performs, and a forming device which is arranged along the transport path of the plastic material preforms after the heating device, wherein the apparatus comprises a first transport device configured to feed the plastic material preforms individually to the heating device, wherein the heating device comprises a second transport device configured to transport the plastic material preforms during their heating,
wherein
the first transport device comprises a first drive device and the second transport device comprises a second drive device and, wherein the first drive device and the second drive device are controllable independently of each other,
wherein the first transport device is configured to be driven at a different transport speed with respect to the second transport device, and the first transport device is configured to be stopped while the second transport device is in continued operation,
wherein the first drive device of the first transport device is only moved when a transfer of the plastic material preforms has to take place, so that the first transport device acts as a transport lock, wherein
the transport device has a third transport device which is configured to transport the plastic material preforms from the heating device to the forming device, and the third transport device has a drive device and which is configured to be controllable independently of the drive device of the first transport device and/or the drive device of the second transport device,
wherein the forming device is a blow moulding machine which is configured to transform the plastic material preforms into plastic material containers by acting upon a gaseous medium,
wherein a fourth transport device, which is assigned to the forming device, is a blowing wheel and a plurality of forming stations is arranged on the blowing wheel,
wherein the forming stations have stretching bars, and
wherein the apparatus has a sorting device which is configured to sort and align the plastic material preforms from a preform chute, and at least one sensor device which is configured to detect faults in the transport of the plastic material preforms, wherein in response to such an error of the transport device, a transport drive can be slowed down or switched off.
