Machine tapes for the printing industry

Siegling – total belting solutions

Top performance level:
Polyester line
machine tapes
For decades, Forbo Siegling has had a reputation as a partner in development
and as a supplier for machine manu­­factures and users in the paper, printing andpackaging industry. In this industry, Siegling Extremultus m­ achine tapes andSiegling Transilon ­con­veyor and processing belts are the first choice for nearly
all functions and processes.

Siegling Extremultus machine tapes have proven themselvesin practically all sectors of the printing industry. From the sheet feeder
to the high performance web folder …

… to various post-press points.

Thanks to the Siegling Extremultus Polyester line ­machinetapes, the potential for quality and productivity of tried-andtested machine designs can be used to the fullest.

The splicing method (Z-splice) does not require any
additional materials and provides the flexi­bility anddurability required by small drum diameters.

The ­highly-modular thermo­plastic tension m­ ember
design with polyester fabric in conjunction with extremely
wear-resistant surfaces means a broad range of applications
is possible: roto­gravure, commercial web offset (heatset)
and newspaper printing (coldset) right up to the highperfor­mance web folder.

Handy Z-punch cutters and small heating clamps makeit possible to fit directly on the machine easily withshorter fitting times.

Commercial web offset
Paper web speeds up to 18 m/s can beachieved only by using folder belts
with special tension members. The
most varied of paper types must becon­veyed through the folder precisely
and reliably, and at the same time thebelts must have a long service life.
With a polyester-based fabric tension­member, the Polyester line meetsthese requirements without cuttingback on edge ­stability or lateral tearresistance.

The Polyester lineTension member
The tension member made of poly­ester fabricembedded in thermo­plastic combines good
damping properties and break resistance withhigh flexibility.

2With its machine tape product range, Forbo Siegling provides
solutions for the special requirements of the various printing processes
and all types of post-press.

Sheet fed printing

Rotogravure printing

Newspaper printing

The exact feeding of the sheets into
the printer is decisive for the continuous production in offset printing.

The folding of freshly printed paper
requires that the belts convey precisely,
gently and without marking in all areasof the folder – above all in the cutting
section.

The abrasive character of printed
news­paper requires that folder belts
in the folder have highly abrasive
resistant surfaces.

In addition to the belts with elastomer
coating conventionally used for sheet
feeders, ever more alternatives withtextile, urethane or soft-polyamide
sur­faces are being used. Thanks to its
optimal load/extension ratio and that it
is unaffected by ambient conditions
the Polyester line does not require any
re-tensioning even after long periodsof operation.

The advantages of the Polyester line
tension member in conjunction with apolyester nonwoven coating are thatthey can even fulfil the demands ofdouble-width folders and minimisesmearing.

Ink smearing is prevented by dehesiveor impregnated surfaces and theservice life is also increased.

Operational coating/friction coating

Splicing technology

Surface coatings/coverings suited for all
requirements in the printing industry:

Siegling Extremultus Polyester line machinetapes are made endless with a Z-splice. Together
with our practical finishing tools, this splicing
method provides significant benefits:– G elastomer coating which is exceptional
for its drag, extreme resistance to wearand gentle conveying without marking andink smear.
– polyester nonwoven with significantly
better smear properties in the folder andgood belt life. It is possible to change theproducts without changing the belt.
– fabric surfaces for universal use with good
release properties and long belt‑life.

– e xtremely fast preparation and fabricationof splice in the machine– no additional materials required– extremely flexible and durable splice–d etailed instructions for all equipment andmachine tape typesThe Siegling Extremultus heating clamps canalso be supplied as belting tool sets completewith accessories or as a fitting set in a practicalcase.
Our tools overview, tool sheets and instructions – also for Siegling Transilon conveyor andprocessing belts – are available on request.

Legend*	The FW value indicates the shaft load at
1 % elongation in N/mm belt width. It
represents a parameter, which in contrast to
the ultimate tensile strength, gives a directindication of the tensile force in the belt.
**	Established in line with ISO 21181:2005.
*** Minimum drum diameters were determinedat room temperature and do not apply toconveyor belts with mechanical fasteners.
Lower temperatures require larger drumdiameters. Belts with profiles or sidewalls
may require larger drum diameters. Pleasesee brochure ref. no. 318, Siegling Transilon

Supplied as:

Siegling Extremultus is permanently antistatic,
to a large extent maintenance-free and has goodchemical resistance to wet conditions, moisture,
white‑spirit, household cleaning agents andsolvents common in the paper and printing
industry. It has limited resistance to alcohols.

– roll material for belt finishing by the customer– endless belts 6)– belts prepared for hot-pressing on site 6)– customised belts with perforations –please enquire

Permanent contact with acetone, solvents,
chlorinated hydrocarbons and concentrated
