Abstract

METHOD FOR LABELING OBJECTS WITH LABELS BEARING A LEGIBLE STAMP PRINTING ON THEIR FRONT. AFTER OR BEFORE THE TAKING OF THE LABELS FROM A LABEL RESERVE STATION WITH SIMULTANEOUS GLUING OF THEIR REVERSE, THE STAMP PRINTING IS APPLIED IN A GLUE-FREE ZONE AND A PRINTING INK IS USED AND, FOR THE LABEL, A MATERIAL WHICH GUARANTEES A CROSSING OF THE INK TO ITS FRONT. THE RECIPROCAL AGREEMENT BETWEEN THE PRINTING INK AND THE LABEL MATERIAL MAY IN SUCH CASES BE MADE ACCORDING TO THE NATURE AND QUANTITY OF THE PRINTING INK AND ACCORDING TO THE NATURE AND THICKNESS LABEL MATERIAL.

Description

Method for labeling objects, such as bottles with

back glued.

  It is known, during the labeling process, to provide the labels with a stamp printing on their front or back In the case of bottles containing a

  drink, stamp printing is, for example, an indi-

  These two requirements are fulfilled by a marking on the back in the case of a transparent bottle With a dark colored bottle, on the other hand, stamping on the back can only be identified with difficulty C This is why, in this case, it was necessary to apply the stamping on the rectangle to the label.

  for optical reasons, but also from the point of view of the handling of the bottles As the front of the labels are often not very absorbent, the printing ink dries only slowly, so that there is a risk that the marking is erased by the brushes when applying

the label on the bottle.

  It is therefore an object of the invention to provide a method for labeling objects with labels bearing a readable stamp imprint on them.

  With a process of the aforementioned type, this result is achieved according to the invention by the fact that the labels are marked on their back before sizing or, after

  sizing, in an area free of glue, the ink of

  pressure and the label material being mutually tuned so that the ink of the stamp printing

  penetrates to the front of the label.

  According to another particularity of the invention, labels having a transparent coating are used.

  and impervious to ink on their front.

  The method according to the invention makes it possible to apply a clearly legible marking on the label The readability of the printing does not depend on the degree of transparency of the object As the application of the printing ink is carried out on the back of the label, there is no risk that the

  marking is erased during further processing of the label.

  quette, namely the intimate application of the label on the object by means of brushes, which immediately following the removal of the label on the object As the risk of erasure is removed, it is also possible to The use of such a printing ink is further advantageous in that it eliminates the risk of drying the ink in the ink mechanism and the characters of the stamp. the impression is visible only because the ink has passed through the label, so it is fuzzy and pale in color and, despite its good legibility, is not as aggressive to the eyes as it is

  In addition to the low proportion of solvent which decreases the risk of drying the ink in the ink mechanism and on the characters of the stamp, the ink must have a high viscosity so that the pulverized paper of the ink label to the front During tests, good results were obtained with an ink that is used by

  authorities for the stamping of fresh meat.

  In the alternative, apply the marking before sizing, for example on the labels still in the box, or after sizing, for example on the glued labels in the gripper cylinder, but still having a surplus free face, we prefer the first solution for two reasons First, it allows

cover this recess.

  Printing can be applied anywhere on the label, especially in the area

  The method according to the invention can be implemented on various known labeling stations However, a labeling station is preferred in which, on a support comprising non-uniformly driven sticking segments.
