The document describes Maan Engineering's Inlinerless Module, which provides a fast, efficient way to apply silicone and hotmelt coatings to paper or film in a single pass. The module can be used as an upgrade to an existing machine or as a standalone system. It has a functional design and provides flexibility and high quality in silicone and hotmelt coatings. The module is controlled by a single control panel and includes stations for web control, silicone coating, hotmelt coating, and other optional components.

1. Inlinerless Module
For efficient top-quality linerless production
Maan Engineering’s Inlinerless Module is developed to provide paper or film with a silicone and hotmelt
coating in one passage in a fast, high-quality and efficient manner. The module, the result of 40 years of
knowledgeandexperienceinthefieldofsiliconeandhotmeltcoating,allowsforeasyproductionof(linerless)
label material. It is designed to be used as an upgrade of an existing machine, but thanks to the addition of
unwind and rewind stations it can also be deployed as a stand-alone system. The strength of the Inlinerless
Module lies in its functional design, as well as the flexibility and quality of the silicone and hotmelt coating.

Controlled by one control panel
All components of the Inlinerless Module and the connected glueing
equipment are controlled with one control panel. This panel is
mounted on a rail that is easily repositioned, so that the machine can
be controlled from any position. This control panel also performs live
monitoring of the values of the various measurements. The system is
based on Lenze software, and has a visual, efficient and user-friendly
interface.
Web tension measurement, web control and pre-treatment
When the label material has been fed into the module it passes through
the Web Control Service Station, which controls the web for all the
subsequent process steps. This is also where the web tension is
measured and controlled, and where corona pre-treatment takes
place. This improves the adhesion of the coating(s) to the substrate.
The corona pre-treatment system is optional in the Inlinerless Module.
Layer thickness measurement of hotmelt coating
The homogeneity and the thickness of the hotmelt coating layer are
essential to the production process of high-quality linerless labels. For
this reason the Inlinerless Module is equipped with an optional coating
thickness measurement system. This system measures the weight of
the hotmelt coating layer during production and provides a non-stop
coating weight distribution model.
Silicone coating with inert curing
The Silicone Coating Station is where the label material is coated with
a thin release coating. The silicone coating can be applied full-face
or in zones, using a 3-roller system. The optional 5-roller system is
available for a lower coating weight. After the silicone coating has been
applied it is instantly cured by means of UV in an inert chamber with a
controlled oxygen content. This results in extremely rapid curing, which
is essential for high-quality linerless labels.
Hotmelt with the high-precision DieRect Roller Coating Head
The pressure-sensitive adhesive coating layer is applied using the
DieRect Roller Coating Head. This applicator uses a roller for the precise
and direct transfer of the adhesive coating to the label material. Control
by three individual pumps allows for accurate setting and adjusting of
the coating weight over the width of the substrate. The coating can be
applied full-face or in zones. The Module can be equipped with a Slot
Nozzle Coating Head for the application of other coating patterns.

4. Development in the
entire label industry
essential to linerless
Linerless labels are the sustainable future
of the label industry. An increase in the
use of linerless labels can be expected
in the near future. Important factors
include the various developments in
labelling technology and cooperation
within the label chain.
Cooperation is essential
It goes without saying that the production
of high-quality linerless labels is
important. Silicone, adhesive, paper and
films suppliers also play an important
role. A growing number of parties are
specialising in the linerless field, thus
increasing the quality of the labels and
the possibilities they offer.
Processing the linerless labels
Processinglinerlesslabelsisanimportant
factor in the success of linerless. In
this field also there are a number of
parties who put considerable effort into
making the linerless product a success.
Dispenser manufacturers such as Digi,
HM systems, Altech and SATO have now
marketed several proven systems for the
processing of linerless labels: industrial,
print & apply, scales and hand apply
dispenser systems.

Controlled adhesive supply
The accuracy of the hotmelt coating is essential for
ensuring high-quality linerless labels. The Inlinerless
Module is equipped with a Drum Melter 200 as standard.
This is a Melt-on-Demand system. A Tank Melter 65 is
installed between the Drum Melter and the applicator.
This buffer unit guarantees a controlled glue supply and
facilitates the exchange of the adhesive drum during
production. Both systems are connected to the control
system of the Inlinerless Module.
