Adhesive tape automation | Guide

Cross bobbins are generally used in automated production processes and workflows. Reason enough to take a closer look at the topic of "adhesive tape automation". In addition, we will shortly be presenting you with options that will significantly simplify the use of cross bobbins.

How is tape applied automatically?

It is important to note that the exact details and procedures for automatic or semi-automatic tape application can vary depending on the specific application and the machines used.

First, the tape is unwound from a roll or dispenser. It is then fed through guiding elements to ensure that it remains in the correct position. In some cases, it is cut by cutting units before being applied to the substrate to obtain the desired length, width or shape.

The next step is to apply the tape to the substrate. This can be done by various methods, such as rolling or pressing. The selection of the appropriate method depends on various factors, such as the type of tape, the surface of the workpiece and the specific requirements of the application.

In semi-automatic tape application, part of the process is carried out manually, while other steps are automated. In such cases, for example, the operator can position the tape manually, while an automated system takes over the pressing.

Adhesive tape application with which materials?

It is important to note that the suitability of a specific adhesive tape for further processing depends on various factors, such as the type of adhesive tape, the surface of the substrate and the specific requirements of the application. In addition, the adhesive tape can be applied in different versions, such as rolls, adhesive strips or adhesive die-cuts, either individually or in multiples.

Acrylic adhesive tapes: These double-sided versions are suitable for a wide range of structural applications and offer good adhesion to various surfaces. The strong, high-performance tapes are often used for permanent bonds in the automotive, construction and other industries.

Double-sided tapes: These types have an adhesive layer on both sides and are often used for assembly and fastening applications. For example, they can be used to join parts together or fix materials to surfaces.

Film-based adhesive tapes: These consist of a thin plastic film with an adhesive layer and are available in different variants. After application, only the adhesive layer remains on the substrate. They can be used for applications such as packaging, labeling, electronics and covers.

Special adhesive tapes: There are also a variety of specialized adhesive tapes that have been developed for specific applications. These include high temperature tapes, anti-slip tapes, insulating tapes and electrically conductive versions. The suitability of these special types for automatic application depends on the requirements of the application in question.

This list is not exhaustive, and there are many other types of adhesive tape that can be used for various applications.

How does adhesive tape automation work?

Please note that specific applications may vary by industry and product. Here are some examples:

Automotive: In the automotive industry, adhesive tape is used for a variety of applications. It can be automatically applied to body parts such as door panels, bumpers, interior trim, emblems and moldings. Adhesive tape is also used for bonding cable harnesses, sealing and vibration damping.

Electronics industry: In the electronics industry, it is automatically applied to circuit boards, display modules, housings, touchscreens and other electronic components. It is used for assembly, fixing components, insulation and protection against moisture.

Packaging industry: In the packaging industry, adhesive tape is automatically applied to cartons, boxes and packaging to seal them securely. It can also be used for applying labels and packaging inscriptions.

Construction industry: In the construction industry, it is used automatically for mounting and bonding components such as window frames, roof membranes, insulation materials and façade panels. It can also be used for sealing, insulation and for fixing floor coverings.

Medical devices and products: In medical technology, adhesive tape is automatically applied to medical devices such as sensors, catheters, dressing materials and skin plasters. It can also be used in the manufacture of medical packaging and plasters.

Problems with adhesive tape application

These problems can have various causes and often require careful analysis and adaptation of the processes and the system. Here are some of the most common challenges:

Positioning inaccuracies: precise positioning of the tape on the substrate is crucial for good adhesion and optimal results. Inaccuracies can occur if the tape is not aligned or guided correctly. This can lead to unclean edges, overlaps or uneven adhesion.

Poor adhesion: The adhesion of the tape may be impaired if the surface of the substrate is not properly prepared. Grease, oil, dust or moisture can affect adhesion. Insufficient pressure during application can also lead to poor adhesion.

Waste of adhesive tape: When applying tape automatically, excessive consumption can occur if the tape is not cut or positioned efficiently. This can lead to unnecessary material waste and higher costs.

Machine malfunctions: Tape application machines are complex systems and can experience malfunctions due to mechanical, electronic or software failures. Such malfunctions can lead to interruptions in production, quality problems and delays.

Changing materials: When applying adhesive tapes automatically, different types or sizes of adhesive tape occasionally need to be used. Switching between materials can be time-consuming and requires careful adjustment of the machine parameters.

Cross Bobbins for process automation

Tailored to your application, we manufacture cross bobbins in cutting widths from 2 mm and running lengths of up to 100 km, depending on the material properties. The spools are made to fit your production line perfectly and avoid the problems mentioned above.

Positioning inaccuracies: Individual cutting widths help you to match the belt material precisely to the production line.

Inferior adhesion: Due to the wide range of materials available, we are able to customize your individual adhesive to suit your production line.

Waste of adhesive tape: Customized and precisely cut adhesive tape materials prevent waste as well as pre- and post-processing in the production process.

Machine malfunctions: The right adhesive tape in the right dimensions can help make process interruptions a thing of the past.

Material and roll changes: Due to the enormous running lengths, the frequency of roll changes is significantly reduced.

To minimize the problems mentioned above, it is important that the machines are properly maintained and calibrated. Regular tape quality checks, operator training and accurate process control can also help to reduce the problems associated with automatic tape application.
