Basic behind tyre re-grooving
The
basic component are-:
- Tyre Inspection
- Tyre Buffering
- Tyre Builder
- Pressure chamber
- Mono rail
- Envelope spider
Tyre
inspection
The
basic shop on which tyre arrives first as name signifies inspection the tyre
which comes for re-grooving
Are
checked thoroughly that there should not be any puncher on tyre & if found
any they are fixed according to their size normally the size of puncture is
double the size of hole in tyre.
Tyre
Buffering
After
passing from stage first i.e. after inspection tyre reaches to buffering shop
here tyre are scratched and leveled by cutters and peelers the extra rubber is
wiped off from the tyre so that when a new layer of rubber is applied the tyre
should be leveled.
The
area which is not buffered via machine is buffered with the help of portable
machine
Tyre
Builder
As
name indicates Builder tyre here are build i.e. a glue called BLACK CEMENT is
applied over a scratched tyre the filling is done to level the tyre surface
after completion of all the above process a NEGUM BOND is applied over the
surface it is just like a layer of glue which holds the new-layer of rubber
which is about to apply on tyre and tyre, This negum bond melts and become
sticky hard on applying the pressure & heat.
(Application of black-cement)
(Application of NEGUM-BOND)
(Application of final layer of
rubber)
Pressure
chamber
Now
with the help of a spider envelope a cover of rubber is put on to the final
assembly of tyre on which re-grooving is to be done the function of this cover
is to remove excessive pressure from tyre when it is in pressure chamber, now
with the help of mono-rail the assembly of tyre is moved inside the pressure
chamber manually/artificially
(Moving of tyre inside the pressure
chamber through mono-rail)
Operating
time of pressure chamber is 3 to 3 ½ hours with operating temperature is 125 c
and operating pressure is 61-191 kg/cm3
(PRESSURE CHAMBER & inside of
Pressure chamber)
