siegling transilon
plasterboard belts
are the very best themarket has to offer

At first glance you might think this is a bold claim to make. But we’re not only confident
it’s true, we have proved it with dozens of installations on all continents. After the market
launch in 2012 most of the major players in the gypsum board industry – both OEMsand end-users – trust in Forbo’s expertise.
In the past, rubber belts and thick high-maintenance PVC
belts were used as forming belts in plasterboard production.
Forbo Siegling has replaced these thick belts with a 9 mm
maintenance-free Siegling Transilon PVC belt including
high-tech fabric tension members.
The success of this product is based on:– Highly accurate thickness tolerances,also around the splice– Superb belt tracking– Extremely flat and hard surfaces– Top abrasion resistance– Superb friction values– Maintenance-free, low elongation– Excellent lateral stiffness

6

These characteristics are essential for the curing process
and make this belt a unique product for the market. What’smore, fast and reliable splicing and easy repair of the belt’ssurface are true solution-driven arguments for end-users.
Scratches and holes from the production process in the oldrubber belts led to vast quality problems occurring in the
gypsum boards and were almost beyond repair. The new
Siegling Transilon PVC belt means that repairs take only amatter of a few minutes without requiring any trained
personnel.
The belts are tensioned and tracked only once during the
run-in period. Due to the two-ply, high-tech fabric tension
member there’s no need to re-tension them every few days.

To fit the belts, Forbo Siegling can offer state-of-the-art
equipment for rental, close to where our customers are
based. A team of dedicated experts and local technicians
are at our customers’ disposal at all times.
Forbo Siegling offers customised support– for fitting endless belts(belts spliced in our factory in Hanover),– for fitting and splicing in the conveyor (belt delivered
as open roll material to the customer’s premises).
To ensure flawless, quick fitting, Forbo Siegling provides
its skills at the planning phase already by carrying out
on-site pre-inspections. The goal is to ensure the projectis planned perfectly and production is commenced after
only two days.

Wednesday, 8 a.m.
The fabrication equipment and plasterboard belt, provided
by Forbo Siegling, have arrived at the production facility.
It’s time to unload.

Thursday, 8 a.m.
Our specialists are experienced and work with state-of-theart equipment that’s especially for plasterboard fitting.
The stepped Z-splice is prepared carefully.

Wednesday, 2 p.m.
It‘s no easy feat, the belt is untensioned, cut, pulled out of
the conveyor and wound up.

Wednesday, 5 p.m.
Now it’s time to really get going. The new PVC belt is on
the special winding device provided by us and is inserted
into the conveyor.

Thursday, 11 a.m.
The splice is in the press. Ideal heating settings and control
units ensure the splice is strong and leaves no markings.

Thursday, 3 p.m.
The belt is tensioned and tracked. After inserting thetaper edge belts, production can start up again.

Production on
solid foundations
Our customers have good reasons to rely on our consistently best-in-class quality standards. In the case of our plasterboard belts, you can inspect belts prior to delivery via
factory acceptance test.
Furthermore all belts come with their own test certificatesand folders that include instructions for handling, cleaning, repairs etc.

TRAINING and Repairs
After each new belt is fitted, our experts train customers’
staff on how to operate, clean and maintain the new
Forbo Siegling belt in an excellent condition.
Forbo Siegling’s optional repair kit enables customers to
repair surface defects such as holes and small scratcheswithin the shortest possible time reliably and by themselves.
Therefore, they aren’t forced to wait and pay for any external
specialists. The tools and materials are chosen specifically for
Forbo Siegling’s unique PVC belt design.
Should serious damage occur and/or you require more
advice please contact us directly or our global service
network.

We offer almost any shape of taperedge belts based on a max. 2.0 mm

arguments for this for this reinforced

Infeed/outfeed,
transfer belts
Reliable board conveying, especially in
wet areas, is an essential criterion for
ensuring waste-free board production.
Exact positioning of the board withoutslippage on the belt protects theedges of belts from damage. Forbo
Siegling offers customized solutions forhard-wearing transfer belts in the crosstransfer, board flipper, dryer in-/outfeed, as well as stacking areas. Basedon customers’ requirements, the belt
can be fitted in horizontal, inclining or
declining positions.

11Power transmission belts
for live roller conveyors and processing machines
The combination of tension member and coating lend thebelts their special profile of characteristics customized tothe type of conveyor and drive task. Highly elastic elastomer
or polyurethane as coating materials ensure smooth andreliable transmission at any time. The splicing method(Z-splice) for aramid and polyester reinforced types does
not require any additional materials and has the necessary
flexibility and durability required for their specific purposeof use.

Modular Belting
Because of their construction conventional conveyor belts
are not suitable for certain applications. Siegling Prolink
plastic modular belts are an excellent solution in these cases:
The material is rot-resistant, durable and physiologically safe.
As a rule cleaning the belts is simple.

Endless technology
As a leading manufacturer of conveyor and power transmission belts, Forbo Movement Systems has in-depth theoreticaland applicational expertise in splicing technology. We keep procedures and equipment technology in tune with current
belting developments through close cooperation with users and equipment manufacturers. We provide innovative andfunctional solutions.
All components are compatible with each other and from one source – for effective and reliable endless splicing:– High quality tools with all the accessories– Comprehensive service– Detailed procedural instructions

For gypsum
fiberboArd plants
Due to its broad range of high quality lightweight conveyor belts,
Forbo Siegling products are well established in gypsum fiberboard plants.
They are found in raw material preparation for conveying gypsum and paper
fibers, to bunker bottoms, feeding and extracting belts, to spreading bin belts
and spreading belts. These are followed by press belts, upper press belts,
forming belts and various belts for board conveying, such as in-/out-feeders
for the dryers and stackers, as well as stack conveyors.
All these different processing tasks require specific belt characteristics such as
durability, lateral stiffness, optimized surface patterns and so on.
Forbo Siegling offers specialised belts for almost any application andprofessional technical support during fitting and maintenance. Please contact
