STRETCH HOODER MH3
(Typical Image)
The MH3 Automatic Stretch Hooder (Patented Pending) is a single unit machine able to
wrap and protect the customer’s product using the Stretch-Hooding System.
The MH3 Automatic Stretch Hooder works using Stretch Film delivered in tubular rolls
with a lateral tear gusset.

It is possible to wrap up to three different product sizes using the same roll or to use the
automatic changing function to have up to three different rolls of film used to suit different
product size
Typical Picture Showing A Double Reel Dispenser.
Picture. 1
An infeed conveyor centralises the pallet and delivers the product to be packed onto the
conveyor under the hooding area of the MH3 machine.
When the product has been delivered, centred and waiting to be wrapped an electronic
sensor monitors the pack position and ensures it is in the correct position.
This function ensures no product is overhanging the pallet outside the pre-agreed
parameters
This is designed to ensure there will be no collision between the hooding arch head and
the product.
When it is confirmed the product is centred and in the correct position the film is stretched
and applied to the product using to a special set of extension fingers which grip, expand
and apply the stretch hood.

The machine generally functions using two main separate sequences. They are instigated
each time a new product enters the machine. The separate functions are done to maintain
maximum throughput on the machine.
Phase 1- : Hoods are prepared on the top of the machine using a system of special
rollers to feed the film.
The coil unrolls to the required length and to suit the pack to be wrapped
The height is automatically read using an external photoelectric reading system mounted
external to the machine (Optional).
The welding and cut unit ensures that the hood will be welded and subsequently cut to
the required length. Once the hood is ready it is transported to the mechanical picking-up
unit.

Phase 2. The hood is transferred from the preparation unit to the hooding area
This unit is composed of clamps for gripping the rolled up tubular film.
The initial opening of the tubular is made by a rotating movement of the N.2 crossbar
fitted with the clamps. It is a synchronized and electronically controlled movement to
widen the stretching hood film.
Each crossbeam has two sets of double clamps giving a total of four, which keep the four
edges of the hood up, open and extended. Starting from the centre of the hood and with
an outwards movement, synchronized with the crossbeam opening the machine forms the
rectangular shape required be put on the pallet.
Now in place, the expanded hood is placed in position over the product using the arch
lowering and coning to the coming down and placing the hood over the product and to the
bottom of the pallet.

The main innovation (Patented Pending) of the MH-3 Stretch Hooder machine film is the
ability to add a new optional hooding system called “Rotate System”.
This system gives customers the ability to pack and hood wrap every product to the
bottom of the pallet without the requirement of a pallet lifting device
The hood having already been cut, welded and positioned (After being partially opened)
on the wrapping unit will wrap thanks to the pre-fitted motorized systems.
The hood will be slightly stretched on the four angles.
The wrapping units rotates on their pins maintaining the film clamped.
“Rotate System”.01 Typical Scheme
At the end of the 180° rotating phase, the hood is kept with the weld upward but the
wrapping units will be placed on the top of the hood itself.
The hood will be stretch to the maximum and it will start the coming down onto to the
pack.
The stretch hooding group takes place while controlling the outside of the film using the
special wrapping unit.
At the final stage of the hooding it is possible to change the angle of the wrapping units in
order to easily remove the film and ensure it is placed in the best position to attach to the
pallet.

“Rotate System”.02 indicative scheme
The mechanical vertical lifting movement transmission is achieved using a chain drive
system (Belt driven available for high speed operation) and is fitted with a safety fall stop
control device.
In the unlikely event of a failure of the lifting equipment, the security system fitted to the
vertical movement will guarantee to prevent it dropping and causing any damage to the
mechanical movement.

machine in both manual and automatic modes.
The conveyor equipment required for the machine (Optional) is normally designed
specifically to suit each application and is not covered by this document
The system can be supplied with a pallet lifting system (Optional); which allows film to be
attached right to the bottom of the pallet which ensures stability of the product in transit
but is not included in this document
OPTIONAL :
·
Double or triple reels which allow customers to have two or three different or equal
pack sizes be wrapped. The selection of the roll to be used will be automatic,
based on the information supplied on the product at point of introduction.
