Claims (15)

1. A method of labeling containers, comprising: providing tape labeling material; supply of individual labels to the vacuum drum; capturing individual labels with a vacuum drum at a first vacuum level created through a first cavity inside the vacuum drum; holding individual labels on the vacuum drum at a second vacuum level created through a second cavity located inside the vacuum drum, wherein the above second cavity is located separately from the first cavity, and the above second vacuum level exceeds the first vacuum level; impact on individual labels while holding individual labels on a vacuum drum with a second vacuum level; and applying individual labels to containers.  2. The method according to p. 1, characterized in that the operation of cutting the tape into individual labels is performed by a cutting device having a cylindrical wall through which a vacuum is applied to hold the tape of the labeling material during the cutting operation, while the specified cutting device has a knife protruding radially outward from a cylindrical wall that rotates relative to the cutting edge, and said cutting device has an opening for creating a vacuum and an arcuate cavity extending from the point near the knife to a second point circumferentially at a certain distance from the knife, while the specified opening for creating a vacuum opens into an arcuate cavity and is located closer to the second point than to the first point, and the degree of vacuum in the arcuate cavity decreases near the knife along compared with rarefaction in an arcuate cavity near the hole to create a vacuum.  3. The method according to p. 2, characterized in that the vacuum of a lower level in the arcuate cavity near the knife reduces the tension on the tape of the labeling material during the cutting process and in which a relatively large degree of vacuum in the arcuate cavity near the opening to create a vacuum leads to the application of increased holding force to the tape of the labeling material in the area located around the circumference at a certain distance from the knife.  4. The method according to p. 1, characterized in that said tape of the labeling material is provided in the form of a roll and is unwound before being fed into the cutting device.  5. The method according to p. 1, characterized in that the specified operation of feeding individual labels to the vacuum drum begins before the end of the cutting operation and the first vacuum level is maintained below a predetermined level to reduce the tension on the individual labels, thereby minimizing the displacement of individual labels on vacuum drum and tearing the labels before the end of the cutting operation.  6. The method according to p. 1, characterized in that the specified operation of exposure to individual labels includes applying adhesive to predefined areas on individual labels.  7. The method according to claim 6, characterized in that said adhesive is a solvent that forms an adhesive surface at the site of application.  8. The method according to p. 6, characterized in that said adhesive is hot-melt adhesive.  9. The method according to p. 6, characterized in that the said adhesive is an adhesive for cold bonding.  10. The method according to p. 1, characterized in that the specified operation of applying individual labels on the container includes, in addition, providing openings for pressurized air on the vacuum drum in that place of the vacuum drum, where the trailing edge of a separate label is separated from the vacuum drum and applied to the container.  11. A method for labeling containers, comprising: feeding a label to a rotating vacuum drum; moving labels onto the vacuum drum initially by means of a first adjustable vacuum level created in the first cavity in the vacuum drum, holding the labels on the vacuum drum by means of the second adjustable vacuum level created in the second cavity of the vacuum drum during rotation of the label by the vacuum drum, processing the surface of the label during it holding the second adjustable vacuum level, and the specified first and second adjustable vacuum levels are regulated Irrespective and applying the labels to the container when it is in partial vacuum drum holding the second variable vacuum level.  12. The method according to p. 11, characterized in that during the specified processing operation creates a third adjustable level of vacuum in the third cavity of the vacuum drum, and the above third cavity has an opening leading to the surface of the vacuum drum at a point during rotation of the vacuum drum, where the adhesive is applied on the front edge of the label.  13. The method according to p. 11, characterized in that the labels are cut into separate segments prior to performing the above moving operation, the above labels are pre-coated with activated adhesive, and the above-mentioned first adjustable vacuum level is maintained below the second adjustable vacuum level.  14. The method according to p. 13, characterized in that the pre-applied adhesive is a heat-activated adhesive applied to the label, which is heated in a certain area while holding the label with a second adjustable level of vacuum.  15. The method according to p. 11, characterized in that the labels are fed during the operation of feeding from a stack of labels.
