Multi oven is studied to meet any kind of customer needs, with various fibres blends, web thickness and weight.
Optionally it could be equipped with impingement air flow (see after) in one or all sections. It is equipped with
double belts with adjustable distance (see after)
- ENTRY ZONE : it will contains various belts mechanisms, that will remain in cold atmosphere
- SECTION 1 : equipped with fan, burner, filters
- SECTION 2 : equipped with fan, burner, filters
- SECTION 3 : equipped with fan, burner, filters
- SECTION 3 : number of sections following the production
- AIR EXHAUST FAN : to remove smokes from oven
- EXIT ZONE : it will contains various belts mechanisms, that will remain in cold atmosphere
- FAN OF THE SECTION : at variable speed
- BURNER OF THE SECTION : industrial type, world wide assisted and equipped with filters
AIR FLOW IN MULTI OVEN – NEW
Optionally the multi oven could be equipped with the possibility of air impingement flow in one or in all
sections. this is used for special applications or air permeable products
Remain however the possibility of working with air trough system = customer could choose the way to work,
without changing the oven.
LINE WILL BE EXTREMELY VERSATILE AND ALWAYS FUTURE PROOF.
Description of air trough working is the same of other ovens.
WEB THICKNESS REGULATION
2 HOT SECTION OVEN + COOLING
Webs coming from a carding + cross lapper system or from an air lay must be protected and controlled in thickness,
in order to meet final user demand. For this reason a fiber bat is held between two conveyors, before to enter into
the oven and all along the process . In this way the top belt will prevent fiber movement and will adjust final thickness.
Belts distance is regulated gradually in various points, with motor driven screw jacks. They are controlled from the
touch panel so the operator can adjust easily in any moment following the final product. The compression is gentle
and gradual, thanks to various points of regulation located along the oven length
– ADDING MORE SECTION, MORE REGULATING POINTS WILL COME –
MOTOR DRIVEN SCREW JACKS
Motors for belts distance adjusting are located out of the oven in clean and cold atmosphere
Following the products our oven could install different belts and different combinations. our great experience guide us in
the choose of various materials and mashes
fiberglass ptfe coated, steel, pps, peek, duofill , hybrid are among the more common used type
EASY TO CLEAN FILTERS
FOR NO STOP PRODUCTION
Air stream may remove fibers and dust from the web and they will reach burner zone with
risk of contamination, burner damage, fire.
To prevent this, air flow is continually filtered before reach the burner at each cycle. Each burner has 3 set of
filters that could be cleaned from outside of the oven, without doors opening.
Oven is equipped with various doors that are used to access to the internal parts, for cleaning and maintenance.
The sealing of the smoke is made with silicon gasket. To get the optimum sealing the doors are equipped with 4 locks
(2 on the left, 2 on the right). These, jointed with special hinges permit a parallel movement of the door that will
close perfectly with oven frame.
Production site, located in any place of the world, is connected via internet with our systems in Italy.
Customer is assisted in real time for any kind of problems, modifications, future adding without the need
to send locally a technician.

Equipped with steel belts, multi functions ovens find application in variety of applications: Natural fiber, Foam chops,
Filters dust, Rubber tire, wood sawdust, newsprints, etc. etc. could be mixed in variable proportion with bonding fiber
to form a web to be fixed into the oven, equipped with double belts.
The belts also prevent shrinkage of the web during bonding and setting, consequently the stability of the web is increased.
