  • the orientation of the second alignment features 18 of the container 2 may be different with respect to the transport direction 24.
  • the partial sleeve 36 with the first alignment feature 6 was applied.
  • the fourth to ninth container 2 with the respectively applied partial sleeve 36 are fixed by the two follower belt 37.1, 37.2 in height. These two belts 37.1, 37.2 engage the containers 2 before a partial sleeve 36 is applied, so that it rests on them after application and is thus fixed at a height.
  • this container 2 can be discharged by means of the pusher 32 and collected in a collecting container 34 ,
  • FIG. 5A shows a schematic plan view of a container 2 of a film sleeve 3, 36, which must be aligned so that it is not arranged in a desired position 42.
  • the first alignment feature 6 and the second alignment feature 18 have an angular deviation 40 with respect to the longitudinal axis 39 of the film sleeves 3, 36.
  • the desired position 42 is predetermined by the arrangement of the second alignment feature 18, which does not rotate the container 2 itself, but merely aligns the film sleeve 3, 36.
  • the range corresponding to ⁇ 5% deviation is indicated by reference numeral 41. Since the first alignment feature 6 is outside the area 41, the film sleeve 3, 36 is not in the desired position 42, but must be rotated to reach the desired position 42 by the angle value 40, ie, be aligned.
  • FIG. 5B shows a view of FIG. 5A After the film sleeve 3, 36 was aligned and thereby spent in the desired position 42.
  • FIG. 6 shows a plan view of a container 2, with a film sleeve 3, 36, which need not be aligned, since the arrangement conditions are met.
  • the first alignment feature 6 and the second alignment feature 18 are in the range of ⁇ 5% deviation 41.
  • the film sleeve 3, 36 can therefore be regarded as being in the desired position 42.
  • FIGS. 7 (I) and 7 (II) Figure 11 is a flow chart of a method of aligning a film sleeve applied to a container using the apparatus described above for aligning a film sleeve applied to a container.
  • step 100 the device is supplied with a flat film tube having a first alignment feature.
  • step 101 when the device comprises a perforating unit, a perforation is formed transversely to a longitudinal direction of the flat film tube by means of the perforating unit.
  • step 102 the flat film tube, without or with perforation, passed over an expanding mandrel and expanded by the Aufweitdorns.
  • step 103 an image or a plurality of images of the expanded film tube is created by means of a first camera device.
  • Image data of the one or more images can be supplied to an evaluation device in step 104 and evaluated by means of the evaluation device.
  • a film sleeve is cut off from the expanded film tube by means of a cutting device when the device comprises the cutting device.
  • a film sleeve is torn off the expanded film tube by means of conveyor rollers when the device comprises the perforation unit.
  • a partial sleeve or in step 108 a full sleeve can be produced in step 107.
  • a container with a second alignment feature is brought into an effective range of the fixing means in step 109, for example by means of a transport device.
  • step 1108 the sub-sleeve is applied by the expanding mandrel to the container by means of the second conveyor rollers.
  • the partial sleeve is thereby fixed by the fixing means on which it rests at least partially in a height of the container.
  • one or more images of the container with the applied partial sleeve are created by means of the second camera device.
  • Image data of the one or more images can be supplied to the evaluation device in step 112 and evaluated by means of the evaluation device.
  • the evaluation by means of the evaluation device can determine the arrangement of the first alignment feature of the sub-sleeve for the arrangement of the second alignment feature of the container. On the basis of the evaluation, it can be determined which angle value of the partial sleeve is to be rotated on the container in order to reach a desired position or also whether it can remain in the applied, current position since this is already at a desired position equivalent.
  • the evaluation can be based on arrangement conditions that may have previously been defined.
  • the placement conditions may specify that a desired position exists when the first and second registration features overlap one another or ⁇ 5% deviation, such as a length measured on the shell surface of the container along the vessel perimeter or with respect to angular deviation from the vessel longitudinal axis ,
  • step 113 if necessary, that is, if an alignment of the sub-sleeve to achieve a desired position is required, driving the rotating means to align the sub-sleeve by turning by the determined angular value.
  • a first shrinkage of the partial sleeve then takes place by means of one or more preshrunk nozzles, so that at least partial fixing of the partial sleeve takes place on the container.
  • step 115 the container with the at least partially fixed partial sleeve is deployed from an effective range of the fixing agent.
  • step 116 the full sleeve is applied to a container having a second alignment feature.
  • step 117 fixing agents engage in a sealing area of the container.
  • step 118 one or more images are taken of the container with the applied full sleeve by means of the second camera device.
  • Image data of the one or more images can be transmitted to the evaluation device in step 119 and evaluated by means of the evaluation device.
  • the evaluation can, as already described in step 112, take place.
  • step 120 the container is introduced into the effective region of the hold-down, whereby the container is fixed between the hold-down and the transport device.
  • step 121 i.e., if alignment of the sub-sleeve to achieve a desired position is required, driving the rotating means to rotate and align the full-sleeve by the determined angular value.
  • step 122 a first shrinkage of the full sleeve takes place by means of one or more pre-shrunk nozzles, so that an at least partial fixation of the full sleeve on the container takes place.
  • step 123 the container with the at least partially fixed full-sleeve is deployed from an effective region of the hold-down device and the fixing means.
  • step 124 an image or multiple images of the container with the at least partially fixed partial sleeve / full sleeve is created by means of the third camera device.
  • Image data of the one or more images can be supplied to the evaluation device in step 125 and evaluated by means of the evaluation device.
  • the evaluation can, as already described in step 112, take place.
  • step 126 the container is discharged in step 126. If the partial sleeve / full sleeve is in the desired position, then in step 127 the container is transported through a steam tunnel in which a second shrinkage, the final shrinkage, of the partial sleeve / full sleeve takes place.
  • step 1208 one or more images are taken of the container with the partial sleeve / full sleeve by means of the fourth camera device.
  • Image data of the one or more images can be supplied to the evaluation device in step 129 and evaluated by means of the evaluation device. The evaluation can, as already described in step 112, take place. If the partial sleeve / full sleeve is not in a desired position, the container is discharged in step 130. If the partial sleeve / full sleeve is in the desired position, then in step 131 the container is supplied to further uses.
