CONVEYING AND PROCESSING JOBS
Horizontal conveying
Even a conveying task which seems quite simple can require a whole hostof belt properties. Forbo Siegling has the best belt type for various goods,conveying speeds, reversing systems, stop & go and accumulation conveying,and other operating conditions. Some examples of the diverse features ofSiegling Transilon include:– troughable to particularly laterally stiff types– exceptionally low-noise to flame-retardant– pyrolysis-resistant to suitability for conveying unpackaged food– non-antistatic to highly conductive and ATEX-approved– surfaces suitable for accumulation ­conveying and especially good grip.

here ensures that the goods can be discharged to the side smoothly,even on wide belts. Flame‑retardance is a “must” in modern airports.

Belts for telescopic conveyors – here being used to unload
lorries – must be designed to run with counter bending andat the same time, to withstand high punctual loads.

4Inclined conveying

Curved conveying

Goods can be conveyed at an incline even on
smooth belt surfaces. The conveying angle isdependent on a variety of factors such as thetype of goods being conveyed, the top face coating and external factors like dust, moisture, etc.

Curved belts from Forbo Siegling are suitable for use in conjunction with a diverse array of belt tracking systems and are
in use on the conveyors of numerous major manu­facturers.

For large conveying angles and for the conveyingof small pieces and bulk goods, Forbo Siegling
offers patterned belts or belts equipped withlateral profiles.

Thanks to largely-automated fabrication, we guarantee
strict adherence to the geometrical shapes and dimensions
required when supplying finished belts.
Dividing curves into several segments makes for a favourable distribution of force vectors in the belt so even heavy
goods can be carried without any problems.

Inclined conveying in the tobacco industry. In this area,
conveying angles of up to 22° are possible for belt types
with smooth surfaces.

5Collection and distribution
When pushers and ploughs are used, the belt’s laterally stiff design
guarantees that it will lie flat and continue to run in a straight line
reliably. The lateral loading and discharge of goods is achieved byusing very smooth, wear-resistant surfaces. Lateral sorters (e.g. carriercells), on the other hand, require very thin, flexible belts whose
surfaces have high coefficients of friction.
Their special tension member construction means that they havevery low energy consumption.

the belt surface to have an extremely high coefficient of friction.

Processing belts
With Siegling Transilon, the gap is often bridged between the classical­conveying function from “A” to “B” and an active function in theproduction process.
For example, in the textile industry our processing belts stack thin layersof web, in large bakeries they form balls of dough, in the wood industry
they compress chip mat in the pre-press, in dairies milk is coagulated on
the belts to form cheese.
Here are just a few examples of process operations.

directly between the belts places
extremely high demands on theprocessing belts.

Top face ➀Tension member ➁Underside ➂Various coating materials, thicknesses
and patterns determine grip, chemical,
physiological and mechanical properties of the belt.

The use of various special fabrics
largely determines the suitability forspecific applications. Belt tracking
properties, load/elongation properties, electrostatic properties, flatness,knife edge and curve suitability are
directly dependant on the fabric construction.

The design of the underside determines the noise emission, wear,and suitability for sliding‑or rolling
support of the belt.

SIEGLING TRANSILONPATTERNS
Forbo Siegling has developed and optimised a wide range of surface patterns
for very different applications. The appropriately optimised surface patterns
ensure for example, ideal grip with demanding goods such as roller suitcasesand good release properties with dough and are also used to emboss
manufacturer-specific patterns on the under­side of chocolate.
Siegling Transilon patterned belts can run at incline angles of up to 30°
without profiles. For larger incline angles they can also be fitted with profiles
and sidewalls (see page 11).

SPECIAL FEATURES
AND PROPERTIES

Food safety

Electrical properties
In numerous conveying and processing functions,the electrical properties of the belt material are
important for smooth operation. As a standard,Siegling Transilon belts are equipped with aconductive tension member which preventselectrostatic build-up in the belt.
Siegling Transilon non-antistatic belts (NA) are notelectrically conductive. They facilitate special
engineering solutions for produc­tion conveyors
where high frequencies are used or regulation
is carried out electromagnetically e.g. in security
screening and in quality control.
Siegling Transilon highly conductive belts (HC)can also divert electrostatic build-up in the goods
conveyed because of their highly conductive
coating and/or the tension member. For the safe
conveying of elec­trical components and otherelectronically sensitive goods.

Thanks to numerous product innovations, Forbo Siegling
contributes significantly to the hygienic conditions in thesensitive production areas of the food industry. This supports you in implementing your HACCP concept. And users
and end users know food has been produced safely.
FDA/EU: All materials used in our food types comply with
the FDA 21 CFR, (EU) 10/2011 and (EC) 1935/2004 regulations
on the materials used and migration thresholds.
Halal: In the food segment, the majority of the Siegling
Transilon PU- and PVC-types are certified as complying
with Halal regulations by IFRC Asia (a member of theWorld Halal Council).

Further special products
In addition to these patterns and features of conveyor andprocessing belts, Forbo Siegling offer numerous special
deve­lopments for various applications including:– belts resistant to UV– belts with silicone coatings– flame-retardant belts– belts for hot goods– silent belts– wear-resistant belts– knife edge belts– troughable belts– ATEX-compliant belts– elastic belts

SPECIAL PROCESSING
Numerous combinations of tension member‑design and coating design are possible. But certain conveyingand processing tasks require more: mechanical, physical or chemical belt properties which can be provided
only by special production processes, combinations of materials and/or finishing (see page 9 and 10).
Brochures 317 and 318 provide information about storing, finishing and fitting, as well as special features andproperties. Further information on request.

Profiles/Sidewalls

Perforations

Belt edge sealing

Conveyor belts with profiles are used
for the inclined and declined conveying of bulk goods and small pieces.
Profiles are available in various shapes
and sizes and can in some cases besupplied as roll material.
To contain goods on the sides when­conveying bulk goods, sidewall profiles
are used – often in conjunction with­lateral profiles.

It is possible to maintain very narrow­tolerances for practically any patternof per­forations in Siegling Transilonmaterial. (Belt material with perforations can not be used for form-fit
transmission of power.)

Belt edge sealing prevents oil, grease,water, foreign bodies and bacteria
from penetrating the belt. At the sametime, it increases the service life of theconveyor belt.

11This additional predection can beapplied to virtually every Siegling
Transilon conveyor belt.

SIEGLING TRANSILONSPLICING TECHNIQUES
Types of splices
The splicing method appropriate for individual applications is dependent on the belt types used
and the prevailing operating conditions. In addition to splice reliability, flexibility of the splice andthe effort required for fabrication are decisive criteria for the selection of the splicing method.
Detailed instructions for all splicing procedures are available on request.

Hot-pressing➀A hot-pressed splice provides the highest durability
and flexibility. Following types are available:➀ Z-splice
Meets the most rigorous of requirements for uniformityof thickness. Very flexible splice, required particularly forknife edge belts. Standard splice for 1 and 2-ply
belt‑types.

➁➁ Stepped Z-splice
Properties comparable to those of the Z-splice. Also
suitable for rugged operating conditions (e.g. soileddrums). Possible for various 2 and 3-ply belt types.
➂ Wedge splice
Splice type for solid-woven fabric and NOVO types.

➂➃ Stepped overlap splice
Especially for 2 and 3-ply belt types with duroplasticcoatings.

➃Cold-pressing
It is possible to cold-press wedge or stepped overlap splices
in independent fitting repair jobs on site. Please notethat such splices have limited strength and flexibility.

12Mechanical fasteners

Splicing Equipment

Mechanical fasteners make it possible to

For reliable hot-pressing (splicing) of Siegling Transilon
conveyor and processing belts, a diverse, tried-and-tested
range of equipment is available.

– 	quickly fit and remove the belt without
disassembling machine components,– 	repair a belt at short notice by insertinga piece of belt material,(please inquire about lacers).

The equipment required for splicing depends mainly on thetype of splice. Other important factors include the conditions under which the splice is to be fabricated (workshopor on-site fitting) and the width of the belts to be spliced.
