Conveyor and processing belts
in the Tobacco Industry
As the worldwide leading manu­facturer of conveyor and processing belts of modern synthetics, Forbo Siegling have developed a product range especially suited to the requirements for
tobacco processing.

The Siegling Transilon product range for the tobacco industry is physiologicallysafe, conforms to pyrolysis regulations (if equipped with an A or E coating), impervious to oils and greases and con­forms to the legal regulations for the conveyingof unpackaged food.
Our close cooperation with original equipment manufacturers and the tobacco
industry ensures that Siegling Transilon, with its chemical and mechanical proper­
ties and the extensive range of accessories, meets the requirements for production reliability and productivity.
Siegling Transilon is quick and easy to splice, maintenance-free, simple to track
and has a long belt life. Further information about type selection, forms of delivery available and accessories can be found on the following pages.
Numerous other Forbo Siegling products are used in the secondary sector – fromthe conveying of the individual cigarette to the handling of larger packed units
for distri­bution. These products are presented only briefly in the overview of thisbrochure. Further information about these is avail­able on request.

3PrimaryProcessing
Bales, leaf tobacco, leaf stems, dry or
flavoured tobacco: in the numerous
stages of processing which tobacco
undergoes in the primary process frombale to finished blend, the con­sis­­tencyof the tobacco, the processing temperatures and the conveying tasks areconstantly changing.
The Siegling Transilon range has a beltwith the right properties to convey thetobacco reliably and smoothly throughall stages of the production process.
Since it can never be completely ruledout that particles of the belt surface
get into the tobacco due to damage ormigration, an ever increasing numberof tobacco manufacturers use belts
which conform to pyrolysis regulations.

Efficient skirting:➀➁➂➃ An appropriate skirt belt depends
heavily on the actual operating conditions.
Forbo Siegling provides innovative andhighly efficient solutions to reflect customer’sspecifications.

In many cases, conveyor belts
equipped with profiles can replace
conventional equipment withmetal rakes, therefore reducing
expensive set-up times.

Various surface patterns (here VN)
can be used when conveying at anincline of over 20°.

Conveying witha troughable belt.

Horizontal conveying on a shuttle
for the loading of the silo.
The belt types with smooth surfaces used here can also be used
for inclined con­veying up to angles
of about 20°.

Conveying of bales:
extreme punctualloads in stop-and-go
operation.

Smartseal belt-edge sealing:
Smartseal belt-edge sealing prevents
moisture and bacteria from penetrating thebelt. The sealing also extends belt life.
A special press heats the edges of the beltmaterial. The melted section at the sides isreshaped, seals the fabric reliably and caneven be repaired.

Guaranteed resistance to pyrolysis:
To be on the safe side for both you thecustomer and us the developer, we have had
the pyrolysis resistance of the corresponding
belts in our range certified by an independent
institute.

Splice types

Patterns– endless belts

The hot-pressed stepped Z-splice,
which is a standard for endless belts,
meets the highest requirements foruniformity of thickness and mechanicalstability (fig. ➀).

In many cases, patterned belts are anaffordable alternative to welded-on
profiles.

Various mechanical fasteners can beused to facilitate belt replacement andrepairs without requiring the conveyor
to be dismantled (fig. ➁➂➃).

– smooth belt run, low noise– open belts prepared for meltand bonded splices on site
– roll material for customer to finish– belts with mechanical fastener– belts with edge sealing (Smartseal)– belts with welded profiles(longitudinal, lateral or diagonal)
Profiles as roll material are also available.

Especially when combined with sideskirts, the VN pattern can be peeled off
at the belt edges. (see fig. below)

Legend●●●●●*	Established in line with ISO 21181:2005**	The smallest permissible drum diameters
were established at room temperature withz-splices and counter bending and do notapply to conveyor belts with mechanicalfasteners. Lower temperatures, profiles andside walls can require larger drum diameters.
On this point, see our brochure “Technicalinformation 2” (ref. no. 318).
rX is the radius of a fixed knife edge.
dX is the diameter of a rolling knife edge.
1) For special applications only.
Not to be used as a conveyor belt.
