7 Film grippers
The hood applicator head prepares the gusseted film tube for the stretch hood
formation. The subassemblies for the individual working sequences are integrated into the frame of the hood applicator head.
The film tensioners stretch the gusseted film tube. For this, the four side fold
clamps take the gusseted film tube at its edges, and the film tensioners move
apart. The film grippers of the four gripper arms grip the gusseted film tube. The
gripper arms swivel downwards, thus opening the gusseted film tube. The side
fold guiding plates help to open the gussets. The side fold pins hold the gussets
while the gusseted film tube is stretched and sealed.
The two sealing rails and the knife are mounted on the sealing bar. The sealing
rails seal the open gusseted film tube into a film hood closed at the top. Then the
knife cuts the film hood off the gusseted film tube.
After the film has been cut, the film retriever pulls the gusseted film tube back
into a defined position. The film brake prevents the cut gusseted film tube from

slipping out of the hood applicator head. The film length measuring device determines the released length of the gusseted film tube.
The individual components are driven pneumatically or by an electric motor.
When a new gusseted film tube is to be inserted in the hood applicator head, the
film brake on the hood applicator head can be activated manually.

For crimping the film hood, the crimping motors approach the crimping bows and
then the film is pulled over the bows. The length of the film to be crimped is determined by the film length measuring device in the hood applicator head.
Technical description
BA-6090103-EN
19.08.09
After the film hood has been prepared, its upper part is crimped as well. Then
the crimping bow supports are moved to the stretch position. In this position the
film hood is pulled over the load.
A diffuse scan on each crimping bow support detects whether the film has torn
apart during stretching or pulling over the film hood. Besides, there must not be
any film on one of the crimping bows any more when the stretch frame is raised.
If the film tears apart or if it is still on one of the crimping bows during raising, the
malfunction "film tear" is indicated. The system is automatically switched off and
the corresponding fault message is displayed on the control terminal.
The four touch-down switches under the crimping bows are used as safety
switches. They prevent the crimping bows from landing on an obstacle during
the lowering process.

Safety instructions
Before starting installation, the personnel working in the area where the installation is carried out has to be informed about the installation work. The whole area
is to be protected against unauthorised access. The barriers have to be provided
with reference plates forbidding unauthorised persons to enter.
Do not permit unauthorised persons to enter! Attach reference plates!
Lifting equipment
Wear protective clothing when carrying out this work!
The lifting equipment is to be selected according to the particular local conditions. The rated load of the lifting equipment must be sufficient.
Installation
Welding work
Warning!
Loads which are incorrectly fastened or components may fall down and
cause serious physical injury or property damage.
Never work or stand under suspended loads! Use only suitable and correctly
functioning lifting equipment and load carrying attachments of sufficient rated
load!
If any welding, flame-cutting and separating work is necessary - also on the
building itself - the electric parts have to be protected adequately. If welding,
flame-cutting and separating work is necessary on the machine itself, check
whether there are any installations attached to the reverse side of the surfaces
to be worked on. During welding work, the lenses of the photocells have to be
covered by a protective band in order to avoid burnt spots on the glass. The
temperature occurring during welding must not exceed 55 °C in the area of the
electric parts.
During welding work, the earthing of the welding machine must be
mounted to a component to be welded so that the current can flow well.

Preparation of installation
The final installation requires the presence of a BEUMER supervisor for supervising the installation and aligning the machine. On site, the supervisor will decide on the way and sequence of installation. The installation sequence depends
on the space available on site and the state of the civil engineering work. Therefore, the following installation description can only serve as an aid and not as an
obligatory instruction.
It is advisable to have the installation carried out by BEUMER personnel.
We do not assume any liability for damage caused by improper work!
Foundation
The place of installation must be appropriate for the static and dynamic loads
and must be free from vibrations. During project planning, sufficient space
around the machine must be ensured in order to facilitate installation and maintenance work.
The positions of the supporting points should be measured and recorded before
installation. This way, the material for backing can be assigned to the respective

Safety photocell and CPSET-M12 muting device
The CPSET-M12 muting device offers the possibility of suppressing the protection effect of an opto-electronic safeguard (AOPD), e.g. when pallets are taken
off the conveyor. The safety function is bypassed by induction loops (muting)
while the pallets are taken off.

Restart or reset
Operation
A restart or reset of the muting device is required if any of the following situations arise:
• The system is activated.
• An incorrect muting function has occurred.
• There is an object in the protected area.
If the fork-lift truck occupies only one of the induction loops but does not interrupt
the area protected by the safety photocell to be muted, the safety device can be
activated by pressing the reset pushbutton once. The muting function is not activated. As soon as the fork-lift truck interrupts the area protected by the safety
photocell, the safety device changes to the OFF state. The muting indicator light
starts flashing. Now it is possible to restart the muting device.
If the fork-lift truck occupies at least one induction loop and, at the same time,
the area protected by the safety photocell to be muted is interrupted during connection, the safety device remains in the OFF state. In this case the muting indicator light immediately starts flashing. Then a complete restart of the muting
device is immediately possible. The reset pushbutton must be pressed twice
within 4 seconds for restarting the muting device. When the reset pushbutton is
pressed for the second time, the safety circuit is activated immediately. As soon
as the reset pushbutton has been released for the second time, the safety device checks the signals of the induction loops for a valid occupation. If a valid
occupation is detected, the safety device remains in the ON state. The system
starts operating in the normal mode again. If an invalid occupation is detected,
the safety device remains in the OFF state.
Danger!
An unauthorised release could result in severe personal injury or death.
Before releasing the start/restart interlock, the operator has to ensure that no

Password protection
To avoid an unauthorised operation of the machine/system, the visual display
system is equipped with a password protection. The passwords are subdivided
into different password levels. If a particular password is assigned to a user, this
also includes the authorisation for performing the functions related to the corresponding password level. If a user for example belongs to password level C, he
is authorised to perform functions of the password levels A to C. One or several
passwords can be assigned to the password levels A to P.
Access authorisation
Password level DEFAULT
In order to carry out functions of the DEFAULT password level, no password
must be entered. All displays which are not attributed to a password can be displayed in this password level. All input fields (parameters) which do not have a
password protection can also be edited.
Password levels A to P
Depending on their significance, the functions are assigned to the password
levels A to P. Before a function with password protection can be carried out, the
corresponding password level is to be activated. If the entered password is not
sufficient, the display or the input field cannot be opened.

The basic requirement for a safe operation of the machine/system is its regular
maintenance. The work set out in the inspection lists must be carried out and the
indicated maintenance intervals must be kept. Maintenance also includes a
regular cleaning according to the operating conditions.
Maintenance
Maintenance work must be carried out by skilled personnel only.
How to maintain motors
Motors have to be maintained according to the manufacturer's instructions. The
documents are included in the annex to these operating instructions.
How to maintain gear units
Gear units have to be maintained according to the manufacturer's instructions.
The documents are included in the annex to these operating instructions.
How to order spare parts
The spare parts list and spare parts drawings are included in a separate chapter
at the end of the operating instructions. The spare parts list includes the data of
the order so as to ensure a correct attribution of the spare parts.
In case of inquiries or orders, please send a copy of the spare parts list including
information on the spare parts required to our spare parts department. You will
find the address in the introduction at the beginning of the operating instructions.
Chain drive
In order to achieve an efficient power transmission and the usual service life of
the chain, the correct chain tension and the indicated lubrication intervals must
be kept. The elongation of new chain drives is especially strong at the beginning
of their operating time. Therefore, the chain tension is to be checked more often
within this time. When the chain is taken up, the chain sag must be about 1 to 2
% of the centre distance. An excessive tension of the chain drive reduces the
service life of the drive components.

How to maintain the sealing rail
BEUMER stretch hood® S
How to proceed
1 Sealing rail
2 Teflon fabric belt
3 Silicone rubber
4 Strip heater
The Teflon fabric belt is to be checked for damage after about 80 operating
hours. In case of burnt spots or holes, the Teflon fabric belt must be replaced. If
the Teflon fabric belt must be replaced, the strip heater must also be checked. If
any pressure marks, cracks, mechanical damage, kinks or blue-colored patches
can be detected, the strip heater must be exchanged as well. If the silicone rubber between strip heater and sealing rail is defective, it must be replaced. For
this, the complete sealing rail must be dismounted.
1. Loosen the wiring on both sides and lift the sealing bar out of the machine.
2. Remove the clamping plate and the Teflon fabric belt.
3. Loosen both clamping angles.
4. Remove the strip heater and the silicone rubber.
5. Place the new silicone rubber on the sealing rail.
6. Fasten the strip heater with the clamping angles. The rounded edges of the
strip heater must point towards the Teflon fabric belt. The strip heater must be
stretched tightly.
