A system that applies strips of material, such as labels, to a cylindrical body, such as a bottle. The system includes a vacuum cylinder that holds the labels. The vacuum cylinder rotates bringing the labels into contact with a rotary application head that applies hot melt adhesive to the passing labels. The rotary application head includes a feed channel system that cooperates with a mask cylinder to controllably apply the adhesive. The adhesive covered label then is fixed to a bottle or other device that is rotating in a carousel.

What is claimed is: 1. A rotary application head for applying hot melt adhesive to a passing label strip material comprising: a housing having a cylindrical chamber passing through the housing and an axially parallel application gap; a vertical feed cylinder arranged coaxially in the cylindrical chamber to form a cylindrical annular space interrupted by the axially parallel application gap, wherein the vertical feed cylinder includes at least one feed channel system running parallel to the application gap; and a rotationally drivable mask cylinder arranged in the cylindrical annular space including outlet openings, wherein the outlet openings controllably expose the at least one feed channel system in the feed cylinder to the axially parallel application gap during rotation; wherein the rotationally drivable mask cylinder is configured to apply the hot melt adhesive during contact thereof with the passing label strip material. 2. The rotary application head according to claim 1, wherein at least one feed channel system in the feed cylinder comprises at least one axially parallel or coaxial central channel and at least one axially parallel row of radial feed holes which lead from the central channel to the surface of the feed cylinder. 3. The rotary application head according to claim 2, wherein the central channel is connected to an exterior annular groove via a plurality of radial holes and the annular groove is connected to a housing hole supplied with liquid adhesive. 4. The rotary application head according to claim 1, wherein the vertical feed cylinder is rotatably adjustable and comprises a plurality of feed systems comprising rows of feed holes wherein the feed systems can be adjusted to the circumferential position of the axially parallel application gap. 5. The rotary application head according to claim 4, wherein the length of the rows of feed holes is different. 6. The rotary application head according to claim 4, wherein both sides of a row of feed holes of a feed system in the vertical feed cylinder have elastically supported closure strips which abut against the mask cylinder. 7. The rotary application head according to claim 1, wherein provided in one or both of the housing and the vertical feed cylinder are wiper devices running parallel to the axially parallel application gap for acting on the rotating mask cylinder before the outlet into the application gap. 8. The rotary application head according to claim 1, wherein a plurality of axially parallel rows of outlet openings are formed in the mask cylinder and distributed unequally over the circumference of the mask cylinder. 9. The rotary application head according to claim 1, wherein at least two rings of outlet openings formed in the mask cylinder extend over the circumference. 10. The rotary application head according to claim 1, wherein lines of outlet openings are formed in the mask cylinder that define a closed curve when unwound. 11. The rotary application head according to claim 1, wherein the rotationally drivable mask cylinder defines an outer circumference extending outwardly of the housing through the application gap. 12. A labelling installation for applying labels to cylindrical bodies, such as bottles, comprising: an unrolling device for label strip material; a rotationally drivable vacuum drum for supplying label strip material or individual labels; a cutting device for separating individual labels from label strip material; a rotating application head for liquid adhesive, wherein the rotating application head cooperates with the vacuum drum, the rotating application head further comprising: a housing with a cylindrical chamber that passes through an axially parallel application gap defined through the housing; a vertical feed cylinder arranged coaxially in the cylindrical chamber that forms a cylindrical annular space interrupted by the axially parallel application gap; and a feed channel system running parallel to the axially parallel application gap; and a mask cylinder arranged rotatably drivably in the cylindrical annular space, the mask cylinder having outlet openings that exposes in a controlled fashion during rotation the feed channel system in the vertical feed cylinder through the axially parallel application gap; a carousel for passing the cylindrical body past the vacuum drum, the carousel further including a bottle carrier for the cylindrical bodies, wherein the bottle carrier brings about a rolling of the cylindrical bodies on the vacuum drum; and a device adapted to charge and discharge the cylindrical bodies onto and from the carousel; wherein: the axes of the vacuum drum, rotary application head and carousel are arranged parallel to one another, and the mask cylinder is configured to apply the liquid adhesive during contact thereof with the passing label strip material. 13. The labelling installation according to claim 12, wherein the rotary drives of the vacuum drum and the mask cylinder are mechanically coupled. 14. The labelling installation according to claim 12, wherein the drives of the vacuum drum and the carousel are mechanically coupled using rotational means. 15. The labelling installation according to claim 12, wherein the vertical feed cylinder is rotationally adjustable and comprises a plurality of feed systems with respectively one row of feed holes, wherein the feed systems can be adjusted to the circumferential position of the application gap. 16. The rotary application head according to claim 15, wherein the length of the rows of feed holes is different. 17. The labelling installation according to claim 15, wherein the feed cylinder is adjustably drivable by a servomotor via a pulley. 18. The labelling installation according to claim 12, wherein both sides of a row of feed holes of a feed system in the feed cylinder include elastically supported closure strips that abut against the mask cylinder. 19. The labelling installation according to claim 12, wherein provided in one or more of the housing and feed cylinder are wiper devices running parallel to the application gap that act on the rotating mask cylinder before the outlet into the application gap. 20. The labelling installation according to claim 12, wherein a plurality of outlet openings are formed in the mask cylinder and distributed unequally over the circumference. 21. The labelling installation according to claim 12, wherein at least two rings of outlet openings formed in the mask cylinder extend over the circumference. 22. The labelling installation according to claim 12, wherein lines of outlet openings are formed in the mask cylinder that define a closed curve when unwound. 23. The labeling installation according to claim 12, wherein the mask cylinder defines an outer circumference extending outwardly of the housing through the application gap.
