CONVEYING AND PROCESSINGWOOD EFFICIENTLY
Forbo Siegling products used in wood-panel manufacturing are the result of specificresearch and close collaboration with OEMs and users for over 50 years. Which is why
our sophisticated belting products can help you exploit the potential of your production
machinery to the full and minimize scheduled and unscheduled downtime.
Splicing equipment and straightforward splicing methods make on-site splicing
and handling child’s play. The belts have long service lives and are easy to track –saving time and costs.
More than 300 service points worldwide ensure spare parts and services.

Power transmission belts Conveyor, metering

Former, accelerator
and transfer belts

The tension members in the various
materials (even in truly endless types)
are embedded in a thermoplastic intermediate layer. Highly elastic elastomer,
urethane, chrome leather, polyamide,
polyester or blended fabrics are used
as coatings. Compared with otherpower transmission products, Siegling
Extremultus power transmission belts
stand part for their better efficiency(≥ 98 %), accurate and even tracking
plus easy handling.

The wide range of Siegling Transilon
belts make any type of cleaning, sieving, metering and gluing jobs possible.

The tension member made of
HighTech-fabric provides a linear, steep
load/exten­sion curve. The top face has
a micro­s­copically thin, matte coating.
All of the belt is very thin and manufactured with low weight tolerances(<  ±1 %).

– Patterned top faces for inclined
conveying–	No caking of the chip mat–	­Consistent speeds– Profiles on the top face andunderside to seal edges in silosor to act as guides– Very flexible lengthways– Flexible and highly accurate Z-splices– Very good directional stabilityproperties– Long service lives– Short take-up ranges, little creep– Good damping characteristics– Superior strength up to 1850 kW–	Bevel- and taper-cone drives

Depending on type, the belts canbe customized for special tasks (alsoas a combination) with:–	­Urethane, PVC and silicone coatings– Good release characteristics–	Especially low fluctuations insplice thickness and weight forcheck-weigher belts– Mechanical fasteners– Minimal load on the chip matlengthways– Precise manufacture of thin sheets–	No elongation during constantoperation– Very short lead times, rapidly reaches
dynamic operational condition– Does not tend to deform after
standing still for a long time on thedrums– Highly laterally stiff– Flexible Z-splice– Highly resistant to hydrolysis–	Best release properties, high release6

Pre-press belts

Ventilation belts

Conveying andprocessing

Forbo Siegling pre-press belts have ahighly modular tension member, madeof aramide fabric with a tensile force ofapprox. 140 N/mm at operational elon­
gation. So they are suitable for heavy ­pre-presses with a nip pressure of up
to 3000 N/cm and belt pull of up to1800 N/cm.

The Forbo Siegling ventilation belts
for pre-presses consist of a special
blended fabric that is durable andstrong. They have a high proportionof warp threads, are highly air permeable and have a very smooth surface.

For the subsequent conveying andpro­ces­sing of the boards Siegling
Transilon conveyor and processing
belts and Siegling Extremultus live
roller power transmission belts withdifferent properties are used. Fromrobust all-­rounders right up to absolutespecialists.

– Minimal expansion of the mat
between the pressure rollers

The extremely strong Z-splice, developed by Forbo Siegling leaves absolutely no marks:– Minimal load on the chip mat
lengthways–	No electrostatic build-up and lower
fire risk, uninterrupted production– Very durable surface–	No adhesion of chips/fibers– Low creep–	Excellent ventilation of thechip mat / fiber mat– Very short take-up ranges.
Differences in the thickness of themat and the resulting different tensile
forces over the width of the belt or
the lateral forces occurring as a resultof the belt tracking are compensatedfor by– Higher level of lateral stiffness and– Higher level of resistance to diagonal
warping.

7– Very good surface quality of theboards– Reliable splice– Different splicing techniques

The belts must have low elongation,
be durable and need little maintenance for simple conveying tasks andwhen cutting to size.
In finishing (veneering, varnishing,coa­ting) the demands rapidly increase:the belts used must be able to position
accurately, be resistant to heat andsolvents and easy to clean.
