The Challenges
There are two challenges in this Product Development
1. The coating is water based , but the min. coat wt. required
is 10 gm / sq.mtr.
2. The original Air Permeability / Porosity , must be
maintained
drying
tunnel
Gap of
approx. 10
microns
2. The original Air Permeability / Porosity , must be
maintained
This can be met with help of a Air Blower attachment as
shown in the figure on the next slide.
drying tunnel
Air Blower
Air under pressure
will be blown on the
coated fabric just
after the Myer bar
The Air velocity could be easily altered by adjusting the
dampers on the Air Blower.
By blowing air on the coated web just after the Myer
bar location, the porosity of the fabric will be
maintained.
Other Coating Parameters
This is a water based coating
The temp setting inside the Drying zone as under
Zone 1: 70 deg C
Zone 2: 80 deg C
Zone 3: 120 deg C
Zone 4: 70 deg C
Coating Speed for the Trial Run : 20-25 mtrs / min.

Coating Machine for Split Leather
Manufacturing
Water borne adhesive is coated on release liner, by comma
coating method ,the same is dried in the drying tunnel and
then it is laminated with the leather sheets at the lamination
end. We have specially designed the lamination , so that
leather can feed in sheet form with help of a conveyor
First Pass

Second Pass
On another release liner , water borne , polyurethane ,
skin coat is applied , dried, and rewound.

Third pass
In this pass the body coat is applied on , the same
side as skin coated side , earlier in second pass.
The dried web is wound on the rewind station.

Innovative Coating Machine for
Insulation Tape Manufacturing
Coating pass no. 1 :
On the first Coating station
, PU water Borne dispersion
( Ready to use ) is coating
on , Silicone Release liner ,
by Kiss Roll coating method
. The coated Si liner then
enters the drying zone, to
flash out the solvent that is
water , to obtain a uniform ,
dry PU film .
A dry coat weight of
approx. 10 Gm/ sq. Mtr is
desired and achieved
Coating pass no. 2 :
The coated web then
enters the second coating
station . Here the RVNRL
compound is coated on
the same side as PU
coated earlier , by Comma
Coating method. Here
also the coated Si liner
then enters the Drying
zone , similar to coating
Pass no. 1
A dry coat weight of
approx. 35 Gm/ sq. Mtr is
desired and achieved
Coating Pass no. 3 :
The coated web then
enters the Third coating
station . Here the HM PS
Adhesive is coated on the
same side as ( PU +
RVNRL )coated earlier ,
by Roller Coating
method.
A coat weight of approx.
25 Gm/ sq. Mtr is desired
and achieved.
