GRIP STAR –FLAT BELTS THAT HOLD ON TIGHT
Grip Star flat belts are gentle with products, but still convey reliably. They take hold ofand release products at precisely the right times. Grip Star flat belts can process paper,boxes, corrugated cardboard and tissue-based products dependably and efficiently.

Grip Star leaves no marks and has all the benefits of rubber.
However, it doesn’t include the typical disadvantages ofrubber such as brittleness and cross-cracking. Due to itsexcellent characteristics and good value, Grip Star is the better alter-native to rubber. This is particularly the case whengood grip, precise positioning, high levels of accelerationand high-performance braking are required.

Customised grip
Grip Star is produced in High Grip or Medium Grip versions
in different thickness and with specific surface patterns.
As folder gluer belts, drag belts, live roller belts and machinetapes, the range’s belts fulfil exacting demands and offer awide range of uses. The majority of the Grip Star belts comply with the (EC) regulations 1935/2004, (EU) 10/2011,
as well as the FDA’s 21 CFR for conveying unpackaged foodstuff.

The decrease in thickness of the Medium Grip coating is significantly lower
than that of rubber.

Long service lives,no cross tears

The pattern on the Medium Gripcoating doesn’t wear off and thesurface characteristics virtually
don’t change. In contrast to rubber,the surface doesn’t tear.
** E stablished under standardised
testing conditions.

Perfect splicing

Sophisticated Forbo tools and processes ensure Grip Star belts
are given perfect splices:– fast and reliable splicing– short dwell times due to appropriate pressure applied– almost invisible splices without any faults

GRIP STAR –TYPICAL APPLICATIONS
Printing industry– in compensating stackers and bundlers– in feeding and discharging– in foil sealing
Postal/letter sorting– as reversing belts– as carrier belts
Offices– in franking machines
Paper processing– in enveloping machines– in tissue processing– in packaging machinery– in winding cardboard tubes
Industrial production– in the solar industry for wafer conveying

Almost all Grip Star Medium Grip products are
EU- and FDA-compliant. They can be used during
the manufacture of packaging and in
the process of packaging foodstuffs.
