An Apparatus For Spraying A Processing Lubricant/Solvent On The Internal Surface Of A Green Tyre
Abstract: An apparatus for spraying a processing lubricant / solvent on the internal surface of a green tyre, comprises a motor-spindle assembly, one end of the spindle being connected to a disc, the other end of the spindle being connected to the motor. A lid is disposed above the disc. Means are provided for lowering the disc into, and raising the same out of, the opening in a green tyre placed below the disc on a platform, the disc, during its downward pass into the tyre being rotatably driven by the motor. A tank containing the processing lubricant / solvent is provided along with means for providing a regulated delivery of the processing lubricant / solvent from the tank on to the upper surface of the rotating disc, only during its downward pass, to cause the processing lubricant / solvent to be sprayed around the internal surface of the tyre, the disc, thereafter, on its upward pass, exiting the tyre.

Specification
This invention relates to an apparatus for spraying a processing lubricant / solvent on the internal surface of a green tyre.
The spraying is done prior to vulcanisation and this is necessary to protect the integrity of the inside tyre surface during the shaping operation which takes place during the process of vulcanisation.
According to the prior art, a spray gun is employed for the purpose of spraying the processing lubricant / solvent on the internal surface of a green tyre.
The problems associated with a spray gun are :
(I) clogging at the spray tip
(II) enlargement of the tip of the spray gun over prolonged use
(ill) maintaining air quality, which is a difficult task
