Abstract

Method for closing packages and / or for labeling articles or packages (8), wherein a closure or labeling section (6) is provided with a printed image (3) on one side and with an adhesive application (5) on the other side before it is applied to the article or package (8).

Description

The invention relates to a method for sealing packaging and / or for labeling articles or packaging.

Various such methods are known, but all operate with predetermined label sizes and shapes. In addition, these are usually pre-printed.

The use of liners on which the labels are delivered is standard.

Predetermined sizes, shapes and imprints make the use very inflexible. The use of liners to cover adhesive surfaces produces unnecessary waste.

The object of the invention is therefore to propose a method which overcomes the disadvantages mentioned. Use of standard papers is desirable.

This object is achieved in that a closure or labeling section is provided with a printed image on one side and with an adhesive coating on the other side, before it is applied to the article or packaging.

Thus, standard papers can be used, which are customized only when used and provided with the required adhesive.

In this context, it is also very advantageous if the adhesive application takes place in advance and this is activated only directly before use.

This significantly expands the available adhesive spectrum.

Another very advantageous embodiment of the invention is when the closure or labeling sections are provided as band material available and cut to length.

As a result, on the one hand to work continuously, but still very flexible.

It is also very advantageous according to the invention if the printed image is applied individually to the sealing or labeling section by means of a thermal method, transfer belt, laser printing and / or ink printing.

So each section can be customized. Color printing is conceivable.

According to the invention it is also very advantageous if the closure or labeling sections are formed linerless.

This avoids unnecessary waste.

Another very advantageous development of the invention is when the adhesive application or its activation by means of spraying, rolling, or by means of a transfer device, whereby thermal methods are conceivable.

This can be realized in a simple manner, the adhesive or its activation.

According to a further embodiment of the invention, it is also very advantageous if first the closure or labeling section is printed, this is then cut or cut according to the printed image or the required dimension, this section then taken with a gripping tool, preferably a vacuum device and before or thereafter provided with the adhesive or activated before the section is automatically or manually placed on the package or article.

As a result, the sections can not only be designed individually but also individually adapted to their size.

It is also very advantageous according to the invention if the trimming of the closure or labeling sections takes place with a cutting device or a punch, wherein a punch can be designed as a rotary punch which can also separate different lengths.

Depending on the application, a cutting device or a punch can have advantages.

It is also very advantageous according to the invention if the trimming of the closure or labeling section takes place not only with respect to its dimensions but also with respect to its contour.

This can also produce irregular shapes of the sections.

According to the invention it is very advantageous if the processing of the closure or labeling sections is endless, wherein the material used can be taken from a roll or coil.

Thus, an at least approximately continuous operation can be created. When using several rolls of material you can work continuously at any time.

It has proved to be extremely advantageous if, when reaching the end of the stock of material, a further supply of material is recognized, wherein the resulting double point is discarded and cut out in the material, this rejection can be done automatically.

This ensures a consistent quality of the sections.

Another very advantageous embodiment of the invention is when a dispersion or a solvent-containing or solvent-free adhesive is used.

This can be glued to many surfaces.

Furthermore, it is very advantageous if the adhesive used is food or drug compatible.

As a result, contamination of the contents are avoided.

Furthermore, it has proved to be very advantageous according to the invention, when the adhesive used is designed to be resolvable again.

In this way, applied sections can be detached again in a simple manner.

In the following the invention is illustrated by means of an embodiment.

The single figure shows a schematic sequence of the method according to the invention.

From a supply roll 1, on which a paper tape 2 is wound material is withdrawn. This paper tape 2 is preferably white, but may also have other colors.

On this paper tape 2 is first in a printing process, there are, for example, transfer prints, laser printing, ink printing monochrome or multicolored conceivable, a printed image 3 applied to the paper tape 2, which may contain, for example, a label or the like.

With appropriate design of the paper tape 2 with so-called thermal paper, thermal printing is also conceivable.

The paper tape 2 can be formed one or more layers.

It is also conceivable that a protective layer 4 is placed over the printed image 3. Here are impregnations or the like conceivable.

On the side facing away from the print image 3 side further an adhesive application 5 is applied.

The adhesive application 5 is preferably a dispersion adhesive. Other types of glue are conceivable. It is conceivable, for example, that first a non-pressure-sensitive adhesive application 5 is made, which is made adhesive, for example by moistening, activation with heat or the like.

Any solvent-based and solvent-free adhesives are conceivable.

Before or after the application of the adhesive, a portion 6 is cut or punched from the paper tape 2.

When cutting or punching not only the length of the section 6 can be set, but also the contour of the respective section 6 are provided.

The thus finished section 6 can then be taken for example with a vacuum device 7, for example a vacuum plate and applied to a package 8 or an object.

The process of making individual labels or closure strips can thus be automated. There are no special adhesive tapes with, for example, PSA adhesive or the like necessary, which must usually be covered with a liner to prevent premature bonding.

Only after activation or application of the adhesive, for example by spraying or by means of transfer rollers, transfer brushes or the like is this active. Depending on the solvent and adhesive used, the open time is different and can be adapted to the respective intended use.

By each individual production of the sections 6, these can be customized, for example, with serial numbers or the like. Even small series with only small quantities can be produced as well as large series.

By the independent shaping of the individual sections 6, for example by trimming or punching, here a rotary punch 9 can be used, can be varied in many ways.

It can also automate the labeling of bottles and still be individualized.

By using color printing, it is no longer necessary to prepare large items of labels or sealing adhesives in advance. These are individually generated on demand and automatically processed.

In this context, it is also conceivable that subsequently soluble adhesives are used again. For example, it is necessary for bottles that the labels can be removed when washing the bottles again.

In addition, no special and therefore expensive use of material is required by the adhesive application when individualizing the sections 6.

If a roll of material 1 now approaches its end, a further or new roll of material 1 can be applied, for example, by pasting over the strips 2.

The resulting double or Ansetzstelle can be manually, semi-automatically or fully automatically cut out, so that all sections 6 have the same quality.
