Basic behind tyre re-grooving


The basic component are-:

  1. Tyre Inspection
  2. Tyre Buffering
  3. Tyre Builder
  4. Pressure chamber
  5. Mono rail
  6. 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 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
