Transparent label dispensers

The category "Electronic Label Dispensers for Transparent Labels" includes machines designed to handle low-visibility substrates through specific detection systems. They ensure precise, consistent, and perfectly controlled dispensing despite the transparency of the labels.

Particularly suited for demanding applications, this equipment ensures reliable detection and excellent repeatability. They optimise productivity, reduce labelling errors, and integrate effectively into industrial environments, where precision, consistency, and performance are essential for the smooth running of operations.

Frequently asked questions about transparent label dispensers

What is a transparent label dispenser?

A transparent label dispenser is an electronic device that separates each label from its liner and presents it ready to be picked up by the operator. As soon as the label is removed, the machine advances the roll to automatically present the next one. This facilitates repetitive labelling and packaging operations.

Why is a specific dispenser needed for transparent labels?

The low visibility of a transparent label can make it difficult to detect for a conventional optical system relying on a difference in colour or contrast. A suitable dispenser therefore uses a system capable of detecting the presence of the label in other ways to ensure a steady feed and avoid dispensing errors.

How does a dispenser detect a transparent label?

The detection system depends on the model. Some dispensers use a mechanical sensor that physically detects the passage of the label. Others analyse the difference in thickness between the label and its liner using an electromagnetic sensor. These solutions allow operation without relying solely on the colour or contrast of the substrate.

What is the difference between a dispenser for opaque and transparent labels?

A dispenser for opaque labels can generally use a standard photoelectric cell to distinguish the label from its backing. For a transparent label, mechanical, electromagnetic, or specially adapted detection may be necessary. Some versatile dispensers accept both types of labels, but this compatibility must be checked for each model.

How to choose a dispenser for transparent labels?

The choice mainly depends on the width and length of the labels, the outer diameter of the reel, the diameter of the core, and the desired speed. It is also important to consider the detection system, the presence of a counter, the feeding mode, and any potential need to dispense particularly wide or long labels.

Can large width transparent labels be dispensed?

Yes, some dispensers are designed to accommodate large width labels and reels. However, the capacity varies by model. It is necessary to check the maximum accepted width, the diameter of the reel, the length of the labels, and the guiding system to ensure smooth unwinding and correct presentation.

How to check the compatibility of transparent labels with a dispenser?

It is advisable to check the dimensions of the label and the reel, the winding direction, the spacing between labels, the thickness of the liner, and the ease of peeling. DERFI can conduct a test with the actual roll used to check detection, liner separation, and the regularity of dispensing.
