Transport Siegling Transilon belts in such a way that they aren’t bent or damagedby sharp edges; don’t tip over the belt edges. Use forklift trucks, hoists, hand carts
or similar to transport roll material and finished belts (depending on the size) andplace them on a firm base or use a transport rod in the winding core. If possible,
don’t remove the packaging until the belt has reached the place where it’s to befitted. When fitting, don’t drag the belt over rough, dirty or wet flooring. In thecase of material prepared for endless splicing, separate packaging protects theends of the belt from mechanical damage and getting dirty. This protective packaging must not be removed until just before the splice is made and when inserting the belt into the conveyor, always leave it on the ends of the belt.
If possible, we recommend allowing the belt to acclimatize for one day before it’sfitted. Please note that major departures from the recommended conditions forstoring and transporting the belts can have a negative impact on any guarantee
entitlements.
If in doubt, contact your local Forbo Siegling rep and have the product number,product name, delivery number, delivery date and fitting date to hand.
Just like all products made of synthetic materials, Siegling Transilon conveyor
belts age and ambient conditions have a major impact on this process. Due tothe variety of materials that can be combined with one another, production
methods and storage conditions, it’s not possible to provide accurate information
on a particular product’s shelf life. However, the risk of products aging prematurely can be reduced if the following recommendations are complied with:– Don’t store them at temperatures below – 10 °C or above + 25 °C.
– The storage space should be clean and ventilated, humidity should be
40 – 65 %.
– Avoid exposure to direct sunlight or UV rays at all costs.
– Don’t store finished belts or unfinished rolls on their edges but hang themon a winding core (if available) or place them flat on a shelf or pallet.
– Only remove the packaging shortly before fitting the belts.
Once the belts have been in storage for two years, we recommend checking
the surface for any changes in the color or pattern:– 	Is the coating softer or harder than usual?
– Is the splice and any film that might have been used still intact?
– Are any profiles still stuck?

4Resistance and Care

Depending on the coating, Siegling Transilon is safe, corrosion and rot resistant,largely impervious to oils, greases, and many chemicals. Further details are available in the product information on our website or on request.
We recommend you test resistances your­self according to prevailing operating
conditions and other influences affecting the belt.
Siegling Transilon belts are easy to clean with lukewarm water. Very greasy patches can be removed with alcohol from V (PVC) coatings or with white spirit from U(urethane) coatings. Then clean with water. (Please inquire about P coatings.)
The right cleaning method ultimately depends on the surface material, the surface and type of soiling. Get in touch with your Forbo Siegling contact if you haveany questions.
We recommend that belt, drums, support rollers and skidplates be kept clean at
all times.

Availability, standard sizes
and tolerances
Establishing lengths for orders
All lengths of spliced conveyor belts on orders
and spare parts cards refer to what’s known as
the inside length (Li) when the belt has not beentensioned. This dimension is not the same as thelength of the neutral axis. With respect to general
tolerances, the difference between these twodimensions in belt lengths as of 3 m is virtuallyimmaterial. However, in the case of shorter belts
and tighter length tolerances, it does have to betaken into account when checking measurements. The inner length (Li) is either establishedbased on the conveyor’s dimensions or a belt
sample. You can find information about this in
our document entitled Establishing the Lengthsof Spliced Conveyor Belts, ref. no. 591.

Fabrication tolerances
These fabrication tolerances are determined by
the fabrication process. These tolerances do notinclude changes in width or length which canarise after fabrication due to fluctuations in ambient con­ditions or other external factors.
The tolerance range may not be extended up
or down arbitrarily. Special tolerances are alsopossible. Please ask.
In order to guarantee repeat accuracy around thesplice there are different length tolerances forTransilon with special surface patterns such as
the CH, R80, R, KN, VN pattern.
Please note the repeat info and different length
tolerances in the technical product data sheets.

When ordering please specify which belts belong to one set so thatthey can be supplied as a set. Slight differences in length which cannot
be avoided with synthetic materials can best be counterbalanced byplacing the longest belts in the center of the set when fitting.

Types of splices

The appropriate splicing method for each belt depends on the belt type, the application and the conditions under which
they operate. Key criteria for selecting the splicing method are, in addition to splice reliability, also the flexibility of the spliceand the properties required by the application technology.
Detailed splicing instructions available on request.

Hot-press method

Cold-press method

A hot-pressed splice provides the greatest durability andflexibility. The following versions are possible:

Customers can cold-press wedge or overlap splices themselves when fitting belts or carrying out repairs on-site.
Please note that the splice strength and flexibility are limited.

■ Z-splice ➀Meets the most stringent requirements for uniformity ofthickness. Very flexible splice, ideal for knife edge belts.
Standard splice for 1 and 2-ply belt types. Standard spliceangle is 90° (60° is possible).
■ Stepped Z-splice ➁Similar properties as the Z-splice.
Also suitable for tough operating conditions.
Possible on various 2 and 3-ply belt types.
Splice angle is 90°.
■ Wedge splice ➂Splice type used for solid-woven and NOVO types.
Splice angle is 90°.
■ Overlap splice ➃Ideal for 2 and 3-ply belt types with duroplastic surface
materials. Splice angle is 90° or 80°.

Splicing equipment

A diverse range of tried-and-true equipment is available for splicing Siegling
conveying and processing belts.
Which is the best device depends on the type of splice and the belt width.
Another factor is the conditions under which the splice is to be fabricated(in the workshop or on-site fitting).
The devices shown are just a selection from our equipment range. Further
information about how splicing devices are used is available on our website oron request.

All work carried out on the conveyor must comply with the manufacturer’s operating instructions and any relevant legal
stipulations or safety regulations in each country. When splicing and repairing Siegling Transilon. follow the instructions for
specific processes and types, available on request. Recommended elongation at fitting 0.2 to 1.0 %. For higher loads werecommend calculating elongation at fitting using our B_Rex calculation program. You can receive the calculation program
by registering free of charge at: www.forbo.com/movement > E-Tools

Operational direction

Fitting

Trial run

Conveyor belts subjected to unusualloads should only be made endlessusing a z-splice or stepped z-splice.
If an overlap or wedge splice is usedinstead observes the operational direction as follows.

Before fitting the belt on the conveyor,
ensure that the conveyor is in perfectoperating condition, taking any necessary steps. Clean drums, support rollers
and skid plate, removing any residues.
Prepare the conveyor for the insertionof the conveyor belt.

After fitting the belt, evenly apply
slight and even tension. Observe belt
travel and if required correct by adjusting the drums.

For unusual loads on the top face fromscrapers, brushes, accumulation etc.
the splice lap must always decline fromthe top face (fig. 1).
For unusual loads on the undersidefrom scrapers, brushes, fixed knifeedge etc. and for belt operation without unusual loads the splice lap must
always decline from the underside(fig. 2).

➀Feed conveyor belt carefully into place
and avoid creasing it. With large belt
rolls use retarder to prevent the beltmaterial from unrolling.
– for endless conveyor belts:
Move take-up unit(s). If necessary, dis­
assemble reversing/drive drum, insert
into belt loop and reassemble.
– for open conveyor belts:
Move take-up unit(s). Feed belt laps
around drums and place in a position
for splicing.
Remove protective coverings from belt
laps. Keep belt laps clean! Clean dirty
belt laps with white spirit or benzine
before splicing. Follow the splicing
instructions for the belt.

➁11

Aftera trial run, tension the conveyor
belt only as much as is necessary toconvey goods properly under full load(see our brochure Recommendations
for Conveyor Design).
For normal operating conditions (temperatures to approx. + 25 °C) move thegravity take-up in order to be able toexploit the take-up range fully.
In cases of extreme temperature variation, set the take-up approx. in middle
so that length fluctuations of at least
0.3 % can be absorbed.
