PRODUCT RANGE

Siegling – total belting solutions

Traditional conveyor belts are often
intended for generic use, but the design
features of Siegling Prolink modular belts
are aimed at providing specific processing and application benefits. This is why
the Siegling Prolink modular belts are aperfect addition to Forbo Movement
Systems existing wide range of belting
products. Our vast experience in conveying and processing applications, combined with our line of highly specialized
belts ensure that we can offer optimized
conveying solutions regardless of theapplication. The Forbo Movement
Systems name is synonymous with not
only superior product quality, but alsowith professional technical support andquality service.

SIEGLING PROLINK
PLASTIC MODULAR BELTING
Modular means adaptable
Siegling Prolink offer a wide product range with manydifferent module designs. Modules within individual
product series can easily be combined. As a result,
Siegling Prolink modular belts can be customized to suit
individual conveying and processing tasks. We will help
you identify the optimal solution for your specific needs.

Design and quality
Sophisticated module design, precise manufacturing and high-quality materials ensure
optimal belt and application performance.
Page 5Siegling Prolink is used successfully in a broad range
of applications in industries such as:– fruit and vegetable processing– baked goods manufacturing– logistics

Functions and types
The right belt for any application! The availability of a wide range of Siegling Prolink belts
are shown by pitch, surface options and application (straight running and side-flexing)

In these areas, Siegling Prolink modular belts often
play a significant role beyond conveying.

Page 7– meat, poultry and seafood processing– automotive and tire manufacturing

Benefits of modular belting
Modular belts are robust and durable and can handle
conveying and processing tasks which may not be
possible with conventional conveyor belting materials
and types.
When assembled and installed, modular belts are endless, but if damage occurs, individual modules canquickly be replaced, thereby minimizing down timeand maintenance costs. Modular belts can be suppliedin any length and width and if needed, functional
modules can be added at any time so belt properties
can be changed if required.
The Siegling Prolink System – Every belt is a specialist!

SIEGLING PROLINKDESIGN AND QUALITY
R & D Concepts
When developing Siegling Prolink modular belts and components, we
collaborate closely with OEMs and end-users to ensure that customer
expectations and application requirements are met. Many Prolink components are designed for particular conveying applications and processing
requirements. This is your guarantee for optimal application performance
when utilizing Siegling Prolink modular belts.

■ application-driven module designs

for challenging requirements■ efficient and effective

R&D processes■ exceptional value

Manufacturing quality
Our state-of-the-art design, tooling and processing technology reflect
the importance we place on the ability to manufacture flawless components and parts according to specifications. A smooth surface is one of
the hallmarks of superior-quality injection molded parts. We place anemphasis on maximizing the quality and consistency of all molded parts.

■ less contamination risk
■ easy to clean■ reliable conveying,even of sensitive products

Tolerances
Siegling Prolink injection molded modules and components as well asassembled belts are manufactured to tight tolerances. This is an integral
part of our overall product design and allows for easy and efficientfabrication, and belt repair if needed. Reliable, actual belt dimensions
are easily obtainable and can help simplify conveyor designs.

■ actual belt dimensions

easily obtainable■ simplified conveyor designs

Materials
We apply the same stringent requirements and demands from our material
suppliers as we do from ourselves. Close collaboration with suppliers andvendors not only guarantees consistently high-quality parts and components when using standard materials but also when special materials areneeded from time to time to meet specific application requirements andconditions. This is especially important if application temperatures areexcessive or if chemical degradation from sanitizers is likely.

5■ superior functionality under

all normal conditions■ long service life for belts

and components

Siegling Prolink modular belts can be customized by using modules with different
surface patterns and openings. Side
guards, profiles and other accessories suchas friction pads, wheel stoppers and Hold
Down tabs can be added to most belt
series, thereby optimizing the application.
Special modules and accessories for further
customization are available, or can be
developed according to customer specifications.
Please contact us if you have a specificrequest requiring a customized conveying
application.

Design characteristics

Design characteristics– Suitable for both straight and radius conveying– Suitable for both straight and radius conveying– Up to 45 % open area for excellent air circulationand drainage– 57 % open area for excellent air circulationand drainage– Stainless steel hinge pins for high load capacity,
lateral stiffness, fewer belt supports and minimum
belt lifting in curves– Stainless steel hinge pins for high load capacity,
lateral stiffness, fewer belt supports and minimum
belt lifting in curves– No potential belt edge catch points due tosafe fixing of hinge pins

– No potential belt edge catch points due tosafe fixing of hinge pin– The combination S5 ST/S11-45 GRT ensures highbelt pull capacety and small radii (CC 1.45) in one

Apart from designing module andsprocket features for specific applications, selecting the optimal materials is
also important in making sure that a belt
is well-suited for specific conveying orprocessing applications.
All materials are tried and tested in themost varied industrial environments. The
specific characteristics of the individualmaterials guarantee ability to handle awide range of applications.

HACCP requirements
New regulatory requirements are forcing food manufacturers to adopt increasingly stringent hygiene standards andsanitation procedures. Conventional conveyor and processing belts often cannot comply with these requirements,
but Siegling Prolink modular belts are designed to effectively support your HACCP concept.

Declaration of compliance
FDA/EU
Siegling Prolink modular belts made of the following materials are proven to comply with FDA 21 CFR as well as the(EU) 10/2011 and (EC) 1935/2004 regulations regarding the raw materials used and the migration thresholds:
