6. FINE ADJUSMENT
Even though the machine has been tried at factory, the final conditions can differ. These are some
different adjustment that allow to achieve the most perfect bag
TERMICAL ADJUSTMENT OF THE SEALS
By varying the sealing parameters, the machine can join any kind of film. The criterion depends
on the final goal:
- higher speed: ▲power, ▼time heating, ▼time cooling
- less electrical energy, more duration of covers: ▼power, ▲time heating
- more esthetic seals: ▲time cooling
- thicker film: ▼power, ▲time heating, ▲time cooling
- very inelastic film: ▼time cooling, ▲time waiting
ADJUSTMENT OF THE BAG
The final adjustment of the bag to the mattress depends on several points:
- how long the mattress advance over the central seal bar
- how strech is the film during the tie up
The fastest way to change the bag adjustment is by acting on the first point, directly on the
keyboard. In the line EXTRA ADVANCE change the value (cents of second that the mattress will
advance over the seal bar). Note that a too low value can provoke the mattress to be catch by the
bar
The stretch of the film must be between two limits: no too high, because can broke the join at one
or both sides, and no too loose, because can present unwinding problems. Note that the stretch is a
combination of the position of the lever, the relative speed of the film respect to the advance of the
mattress (adjustable by inverter) and the relative speed of the film respect to the bar when moves
down. For initial adjustment, keep the speed of the rolls as similar as posible to the advance of
mattress (watch the lever angle to stabilizate), and adjust the speed of the arm to the desired
stretch
The position of the central seal can be moved by changing one of the film stretch
LONGITUDINAL ADJUSTMENT OF THE BAG
When wrapping mattresses thicker than 10 cm, the press compresses its top and bottom in order to
approach the border before sealing, leaving a better adjusted bag.
On depending on the kind of film and mattress, to achieve this could be easier by keeping some
distance between the mattress and the sealing bar. This adjustment is made by:
- fix side: move the fix end on the module nº1 in order to approach or separate the mattress
- movable side: change the data on the keyboard called LATERAL ADJUSTMENT (bigger
values provoke bigger separation) or move the end-detectors
SPECIAL ADJUSTMENT WHEN USING BOOT SYSTEM
In order to keep the same strenght on every roll, is very recommendable to reduce the rolls speed a
little. This way, the coneyor will help for unwinding the rolls, avoiding different speeds
Also, the parameter ‘Time retro roller’ can be increased with the same purpose
