[0050] figure 1 Denotes a plant 1 for the treatment of containers 2 which are preforms and containers produced from preforms by a stretch blow molding process, which are in figure 1 Shown by · or dots. The plant 1 comprises a stretch blow molding machine 10 , a labeling machine 20 and an infusion machine 30 .
[0051] In the stretch blow molding machine 10, a preform 10 of plastic material such as PET (polyethylene terephthalate) or PP (polypropylene) is heated in a heating device and passed through the stretch blow molding process Shaped as a container 2 for liquids, such as a bottle. The containers 2 for liquids produced by the stretch-blow molding machine 10 are fed via a transfer carousel 40 to a labeling machine 20, labeled by the latter, and then fed via a transfer carousel 50 to an infusion machine 30 which utilizes at least one The liquid fills the containers 2 and then seals them.
[0052] In the labeling machine 20, the rolled labels are supplied in bulk to the c...

[0070] The second embodiment is the same as the first embodiment except for the basis of determining whether to interrupt the labeling process of the container 2 . Therefore, only those parts of the second embodiment that are different from the first embodiment will be described below. The same parts and parts having the same function are provided with the same reference numerals.
[0071] A labeling machine according to a second embodiment, such as Figure 2-5 As shown and above, there is a storage device 60 for storing labels and a second detection device 61 for detecting a predetermined packing state of labels in the storage device 60 .
[0072] The second detection device 61 is designed in such a way that each label roll on which the label strip is wound is connected with a sensing tool, which detects the end of the label roll and is connected to the control device 24, that is, it can send The detection signal is sent to the control device 24 . To express it more precis...

[0079] The third embodiment is the same as the first embodiment except for the design of the labeling machine. Therefore, only those parts of the third embodiment that are different from the first embodiment will be described below. The same parts and parts having the same function are provided with the same reference numerals.
[0080] The labeling machine according to the third embodiment has two cutting devices or strip bending devices and two labeling devices. In this case, a cutting device or a labeling strip bending device is associated with a labeling device. The two cutting devices or strip bending devices and the two labeling devices are also referred to below as first and second cutting devices or strip bending devices and first and second labeling devices. The first cutting device or the label strip bending device and the first labeling device in the third embodiment are the same as the first cutting device 21 and the first labeling device 22 in the first embodime...
