Abstract

A method and apparatus for the circumferential labeling containers where the individual containers may have at least one varying dimension, due to manufacturing tolerances. The method and apparatus may provide more consistent labeling of individual containers in the run of containers.

Claims

1. A method for the circumferential, wraparound labeling of containers comprising bottles or other such containers, the dimensions of which may vary from container to container within manufacturing tolerance, to thus provide a consistent appearance of the labeled containers, said method comprising:

sensing at least one of;

a circumference and a height of a container;

determining a length and/or a height of an individual label to be cut which corresponds to the sensed circumference and/or height of said container;

printing label information on an endless strip;

cutting an individual label for said container to the determined length and/or height;

wrapping said cut label around at least a part of the circumference of said container; and

repeating the above steps for additional containers to compensate for manufacturing tolerance of the additional containers and providing a consistent labeled appearance for the additional containers.

2. The method according to claim 1, wherein said wrapping comprises wrapping said cut label about said container without any overlap of any portions of said cut label.

3. The method according to claim 2, wherein said wrapping comprises wrapping said cut label about said container and abutting edges of said cut label to one another.

4. The method according to claim 3, wherein said label information comprises an image, and said printing comprises adjusting dimensions of said image to correspond to the sensed circumference and/or height of said container, and then using a print head to print said image on said endless strip.

5. The method according to claim 4, wherein said image is provided with angle marks for the actuation of a cutting device and/or of a print head as a function of the angle in the circumferential direction and/or the vertical axis direction of said container.

6. The method according to claim 5, wherein the image is stored in a control unit and is provided with the angle marks.

7. The method according to claim 6, wherein said print head is at a fixed, specified distance from said endless strip, or the distance of said print head from said endless strip is set adjustably.

8. The method according to claim 7, wherein said printed image comprises both artwork and a pattern, which are applied individually or both to the container without any overlap.

9. The method according to claim 8, wherein one of (i), (ii), (iii):

(i) said artwork is applied to said endless strip perpendicular to the circumferential direction on the basis of its dimension in the vertical axis direction;

(ii) said artwork is applied to said endless strip perpendicular to the circumferential direction on the basis of its dimension in the vertical axis direction; and

said artwork is applied to said endless label strip on the basis of the size and shape of the container, and wherein there are different distances between individual pixels in the circumferential direction and/or the vertical axis direction, or the distances between the pixels in the circumferential direction and/or the vertical axis direction is varied or fixed;

(iii) said artwork is applied to said endless strip perpendicular to the circumferential direction on the basis of its dimension in the vertical axis direction;

said artwork is applied to said endless label strip on the basis of the size and shape of the container, and wherein there are different distances between individual pixels in the circumferential direction and/or the vertical axis direction, or the distances between the pixels in the circumferential direction and/or the vertical axis direction is varied or fixed; and

said artwork partly or completely fills said pattern.

10. The method according to claim 9, wherein:

said artwork is applied to said endless strip perpendicular to the circumferential direction on the basis of its dimension in the vertical axis direction;

said artwork is applied to said endless label strip on the basis of the size and shape of the container, and wherein there are different distances between individual pixels in the circumferential direction and/or the vertical axis direction, or the distances between the pixels in the circumferential direction and/or the vertical axis direction is varied or fixed;

said artwork partly or completely fills said pattern; and

said artwork is provided with one set of angle marks, and said pattern is provided with another set of angle marks.

11. The method according to claim 10, wherein said method steps are performed for a run of containers of a same nominal size.

12. The method according to claim 11, wherein said containers comprise blow-molded plastic containers.

13. The method according to claim 1, wherein said method steps are performed for a run of containers of a same nominal size.

14. The method according to claim 13, wherein said containers comprise blow-molded plastic containers.

15. The method according to claim 14, wherein said wrapping comprises wrapping said cut label about said container without any overlap of any portions of said cut label.

16. The method according to claim 15, wherein said wrapping comprises wrapping said cut label about said container and abutting edges of said cut label to one another.

17. The method according to claim 16, wherein said wrapping comprises wrapping said cut label about said container and abutting cut edges of said cut label to one another.
