Abstract
A mixing and proportioning apparatus for multi-component plastics materials such as polyurethane comprises a number of tanks, a mixing chamber and a separate pipe connecting each tank to the mixing chamber. The tanks are provided with pressurizing means for causing the components to flow through the pipes and each pipe is provided with a metering mechanism to control the flow of the component through it. The metering mechanisms of the different pipes are all positively coupled to each other so that the rates of flow of the components through the pipes are all kept in constant proportions.
