However, in both the preliminary dispersion tank and the dispersion tank, the reinforcing material is dispersed by the stirring action of only the suction gas from the ejector, so the gas flow rate is not very high and the stirring effect is not perfect, and the dispersion is still improved. There was room for improvement in this respect.
本考案の目的は、補強材分散手段を一段と分散

A characteristic configuration of the present invention is that a reinforcing material dispersing means for dispersing the reinforcing material from the replenishing tank into gas and supplying the reinforcing material to the mixing section with the pressurized gas is configured to separate the reinforcing material supplied from the replenishing tank and the blower. Consists of a closed primary dispersion tank that mixes gas supplied under pressure, and a closed secondary dispersion tank containing a built-in rotary dispersion vane that is rotated by the reinforcing material mixed gas supplied under pressure from the primary dispersion tank. In particular, its functions and effects are as follows.
つまり、一次分散槽で補強材を送風機からの加
圧ガスで攪拌分散させるから、必要に応じて大量
