The rotary head is shown in detail in FIG . It consists of two parts 12a and 12b of different diameters according to the diameter of the upper and lower part of the container to be labeled. The two parts 12a and 12b have ribs and grooves 15 and 14 on the boar part and 15 and 16 on the lower part. The flutes 14 and 16 take belts or straps 17 and on, so-called. Smoothing belts, the speed of which corresponds exactly to the linear speed on the circumference of the upper and lower part of the container to be labeled, without any slippage between the belts and the corresponding cylindrical parts of the container, so that there is no pinching or pressing of the labels.

To hold the labels 2 and 5 on the upper and lower parts of the rotary head, suction holes 19 and provided, which are provided on the top of the ribs 15 and 15 of the two parts of the rotary head. By corresponding channels, these suction holes are connected to a vacuum line. About the difference in diameter balance between the top and bottom of the turret 12 and place the labels on delrv To transfer containers, the belts 17 and 18 are urged back by independent guide rollers 21 and 22, the go back and forth against the axis of the transport path 25 can, so that a precisely defined Aufbringstellung arises, the - ^ en different diameters of the cylindrical parts dss pi ':? - ^ _ers corresponds.

One sees in Fig. 2 in thick lines the individual phases of the unwinding of the labels 2 on the upper and lower part of the container, where 2b is the beginning of the label 2 and '^ b is the beginning of the label 5 . in jig. 2 it has been assumed that the large label t> covers the surface of the container over the entire circumference.

You can see in Pig. ;> that the container is out of the way are advanced by a feed screw 27 without Loss of time each container in the interior of the glci / rolling limited gutter brings. You can also see the Ge andrucicvorrichtung. The containers are in the smoothing path pushed through the rear part of the feed screw. One m advantageously for this purpose the pitch length of the Increase the feed screw in the last, working part. When the snail loses contact with the container, then this is already on the smoothing path in a length that corresponds to a part of the rope diameter This arrangement avoids the disadvantage of other known labeling devices? which for a certain period of time Container - simply placed on the conveyor belt - freely left to seibot. This arrangement also allows great accuracy of the distribution of the containers at the start of the smoothing device with regard to the distribution of the labels It also makes it possible to select the beginning of the application of the label with great accuracy.
