for the paper industry
and letter sorting

The amount of paper types used
nowadays seems endless:from packaging paper, cardboard,tissue, writing and printer paper topaper types for newspaper printing,offset, SC, LWC, ULWC, HWC and art
paper as well as siliconised paper,
NCR and thermo­sensitive paper types.
It is this variety, both in paper
processing and letter sorting, thisvariety places high demands on thebelts used, both in paper production
and letter sorting. For this reason we
have been a development partner andsupplier to original equipment manufacturers and users for decades. This
expertise has produced our comprehensive range of Siegling Extremultus
machine tapes for all appli­cations andthe processing of each type of paperin these sectors.

Further Forbo Siegling products
relevant to the paper industry can befound in the following brochures:
Siegling Linpack folder and carrier belts (withnatural rubber Linatex coated power trans­missionbelts) are used in the paper industry and letter
sorting and elsewhere as pick-off belts.
Siegling Linpack power transmission belts arehighly specialised products, which is why they are
shown separately in another of our brochures(ref. no. 244).

Siegling Extremultus machine tapes excel
because of their friction coefficients
adapted to par­ticular functions, top
coatings kind to paper, good release andgrip characteristics and long service lives.
The types in the Siegling Extremultus
E+A series are the outcome of ourresearch and develop­ment work.
Their aramide or poly­ester tension
member means they have little elon­
gation at fitting, high flexibility and are
not sensitive to fluctuations in ambientconditions.
The splicing method (Z-splice) for thesetypes does not require any additional
materials and has the necessary flexi­bility
and durability required for small
corner radii. Easy to handle Z-punchpresses and heating clamps make simple
fitting directly on the machine possible,
reducing the down times.
Thanks to these advantages maximum
quality and productivity potential frompaper processing and letter sorting
machinery can be achieved even moreeasily.

4With its new machine tape range Forbo Siegling provides solutions
for the special requirements of the various manufacturing processes
and all sorts of further processing and conveying.

Cross cutters

Letter sorting machinery

The most varied types of paper and card­board have to beprecisely conveyed in the cross cutter at very high speeds
without leaving any marks through each pro­duction stage.

In letter sorters, abrasive types of paper and letters with fragile
contents are commonplace.

Apart from the machine tapes for the P series the E series types
are perfect for this type of demanding usage.
Even at fluctuations in ambient conditions and after long
operational periods no re-tensioning is required, they aresuitable for small roller diameters, laterally stiff and have strong
edges. Their relatively low elongation at fitting means that theshaft load is minimised.
Long service life and quick Z-splicing without additional
materials minimise fitting and the resulting down times.

5Flexible machine tapes can deal with these sorts of applications
very easily.
The elastic types in the Elastic series are used mainly for verysmall deflections without take-up systems.
In other applications the E series types get to grips withconveying materials smoothly even under extreme conditions.
Both series have long service lives.
The quick Z-splice without additional substances and excellent
lead times guarantee low fitting times. Down times are reduced
to a minimum.

and conveyor belts 3)– Prepared power transmission and con­veyor belts for heated splicing on site 3)– Special designs with perforations onrequest.

Chemical resistanceSiegling Extremultus has a permanently
antistatic finish, is almost maintenancefree and chemically resistant to:
Wet conditions, moisture, spirits, household cleaners and solvents normallyused in the paper and printing industry;
resistant to some extent to alcohols.
Permanent contact with acetone, solvents, chlorinated hydrocarbons andconcentrated acids should be avoided.
Further information about chemical
resistance available on request.

It represents a parameter, which in contrast
