Method of and apparatus for introducing pulverulent material into a tire

摘要

A method of and apparatus for introducing pulverulent material into a tire through a tire valve stem is performed by confining a predetermined amount of pulverulent material in a cylindrical chamber having axially spaced and radially offset inlets and outlets, subjecting the confined pulverulent material to pressurized air which is transformed into a cyclonic air current within the chamber by the radially offset inlet and outlet, and introducing admixed air/pulverulent material from the chamber into a tire through its associated tire valve stem.
