One of the most common applications for which industrial brushes are used, aside from cleaning, is the application of stickers in labeling machines.
Labeling machines are devices whose primary mission is to attach a label to a container or bottle. Their operating principle is based on: the label feeder positions the labels on the adhesive scraper and moves them to the gluing cylinder where an adhesive base is applied. The labels are then placed on the containers or bottles through the labeling carriage.
Once the labels are positioned on the container, they slide along a mechanical belt that guides them to pass between these industrial PA6 nylon fiber brushes. These brushes apply constant pressure to properly fix the adhesive and smooth the label over its entire surface.
In the case of multiple labeling, which occurs in some wine bottles, one set of brushes handles the smoothing and adhesion of the main labels, while another set takes care of the smaller labels.
Technical brushes for labeling machines tend to be somewhat more complex than usual due to the geometry they need to have.
For labeling bottles and containers, it is very common for the labeling machine to be designed with a brush that matches the shape of the bottle. This requires manufacturing the brush either on elastic bases or on rigid bases with the preform curve.
Additionally, it is very common for brushes for labeling machines, especially those designed for smaller labels, to be slats with inner holes, either square or round. These are moved by a guide or calibrated bar inserted into the hole, allowing very effective positioning, which is necessary for a good labeling process.
The main advantage of using industrial brushes for applying stickers in labeling machines, compared to other technologies and components, is that the brush ensures constant, progressive, and smooth pressure across the entire contact surface. This avoids the formation of bubbles, as the bristles of the brush start to press on one side and expand the contact surface to the other side to evacuate the air.
