2 Safety
2.1 Proper usage
The deniroll ® curve support is a roller component to provide
horizontal support to the inner curve in curved modular belts.
The support can be retrofi tted into existing conveyors. All
other purposes are not considered proper usage.
2.2 General safety instructions
The deniroll ® curve support is state of the art and complies
with recognised technical safety regulations. If used improperly,
risks can occur. The deniroll ® curve support may only
be used when in perfect condition. To exclude the possibility
of putting the user or other persons at risk and to avoid
damage, the deniroll ® curve support may only be assembled,
maintained, repaired and operated by technically trained
personnel.
All work on and operation of the deniroll ® curve support must
only be carried out when the following are complied with:
– This stipulation
– The conveyor/conveyor system‘s technical documentation
– All relevant statutory stipulations and regulations
regarding technical safety.

Caution
Before carrying out any assembly, maintenance and
repair work, the main switch on the conveyor must be
switched off and prevented from being switched on
again.
Caution
Do not reach into the deniroll ® curve support when
the conveyor is being operated. Particularly at the
beginning of the inner radius of the curve (1), parts
of the body and items of clothing can be pulled in
between the modular belt and the curve support.
There is a risk of injuring yourself (fi g. 2.2.1).
2.3 Operational conditions
The deniroll ® curve support consists of several components
and materials. A separate list on the deniroll ® curve support’s
resistance states its resistance to different contact media.
deniroll ® curve supports are all suitable for contact with water.
All materials used are resistant to hydrolysis. The deniroll ®
curve supports are not explosion protected and are operated
under the following ambient conditions:
– Ambient temperature in line with instructions in
the data sheet
– Normal atmosphere (no oil or gas atmospheres,
no corrosive atmospheric components).
There is no guarantee that the curve support will function
properly if used in temperatures below or above those
specifi ed. In certain conditions, static build-up can occur
when using deniroll ® curve support. In environments with
explosion risks, the appropriate regulations for components
used in such environments must be taken into account.

3 Outline
3.1 Principle/structure
The deniroll ® curve support is a roller component to provide
horizontal support to the inner curve in curved modular
belts (fi g. 3.1.1). The rotating rollers are contained in a roller
belt (3) that is guided in both guidance plates (1 and 2) in a
groove (5) (fi g. 3.1.2). The structure shown is an example and
the design can be different, while the principle of how it
works is the same.
The support can be retrofi tted in existing conveyors.

4 Assembly
4.1 Assembly instructions
The deniroll ® curve support (1) is affi xed with metal brackets
(2) or other components to the frame of the curve (3)
(fi g. 4.1.1). Metal brackets with long holes make positioning
easier.
Fig. 4.1.1
➊
➋
Attention
The components used to affi x the curve support must
be designed in such a way that they reliably absorb the
radial forces and the moments that occur as a result
without deforming.
4.2 Assembly tolerances
Attention
The conveying line must be geometrically correctly
positioned for the deniroll ® curve support to work
reliably.
The following fault tolerances must be complied with during
fi tting:
– Angle fault a to the curve path ≤ 1° (Fig. 4.2.1)
– Angle fault ß to the conveying level ≤ 0,5° (Fig. 4.2.2)
– Maximum height difference between all contact points
mass a ≤ 1 mm (Fig. 4.2.3)

4.3 Retrofi tting procedure
1. Switch off the conveyor and secure from being switched
on again.
Caution
Before carrying out any assembly, maintenance and
repair work, the main switch on the conveyor must
be switched off and prevented from being switched
on again.
2 Open the modular belt around the curve in accordance
with the conveyor manufacturer’s instructions and if
necessary remove the old guidance section.
Comment
In the inner radius, the conveyor frame can be in the way
of the deniroll ® curve support and if this is the case a
notch must be applied.
3 Mark out the exact positions of the drill holes on an
auxiliary plate (1). Make drill holes to fi t the diameter of
the screws (fi g. 4.3.1).
4 Position and affi x, or adequately weight down the
auxiliary plate (1) on the curve’s slider bed (2) or the
sliding strips in accordance with section 4.2. (fi g. 4.3.2).
5 Provisionally affi x the components concerned (3) – in
this case the brackets – in the right position. The right
distance from the top edge of the slider bed can be
achieved by applying spacers that are thick enough (4).
Fit fi xing components (3) to the inner radius of the curve
(fi g. 4.3.3).
Comment
The fi tting height must be selected so that the modular
belt does not come into contact with any fi xed parts of
the deniroll ® curve support and so that as much as
possible of the areas at the side runs on the rollers.
6 Loosen the screws between the fastening components
and the auxiliary plate. Remove the auxiliary plate and
spacers.
7 Assemble the deniroll ® curve support (5). Check the
positioning of the curve support in accordance with
section 4.1 and correct if necessary (fi g. 4.3.4).
8 Close the belt in the curve according to the conveyor
manufacturer’s instructions.
9 Check the positioning of the deniroll ® curve support again
and adjust if necessary.
– The play in the whole of the curve should be
constant between the modular belts and any
protruding guidance plates.
– The modular belt must not come into contact with any
fi xed parts on the deniroll ® curve support.
10 Commission the conveyor according to the conveyor
manufacturer’s instructions.

5 Operation
5.1 Commissioning/re-commissioning
Examine the inner radius of the curve to ensure there are no
foreign bodies and if necessary remove these. Switch on the
conveyor and observe. If the deniroll ® curve support is not
operating evenly and without vibrating, switch off the
conveyor and eliminate the problems. One of the causes of
uneven tracking can be assembly faults and foreign bodies.
5.2 Shutting down
To shut down, the system must be switched off at the main
switch and secured from being switched on again.
Caution
The machinery must be shut down in particular before
all assembly, maintenance and repair work is carried
out.
5.3 Disposal
Disposal must be carried out in line with valid stipulations.
6 Maintenance/cleaning
6.1 Maintenance
The deniroll ® curve support needs no maintenance and must
never be lubricated.
6.2 Cleaning
Soiling can lead to increased wear and tear on the deniroll ®
curve support and other components on the conveyor. To
guarantee the curve support works perfectly, we recommend
you clean it regularly. Cleaning intervals and methods depend
on the level of soiling and the specifi cations from the conveyor
manufacturer. Cleaning can be carried out in the
following ways:
– By water jet with low rinsing pressure or
– Carefully, from a distance with a water jet at high pressure
(fl at fan nozzle).
In both cases, commonly available mild cleaning agents can
be used.
Attention
Particularly in the food industry, hygiene regulations,
the relevant statutory specifi cations and the regulations
laid down by the machinery manufacturers must be
complied with.
