Abstract
Improvements in the machines for injecting sands for cores, characterized in that the sands moistened with synthetic resin, liquid, thermostable, stored in a vertical hopper of adjustable position, can be strongly pushed towards the core box by a current of air from a tube that axially crosses the hopper having its outlet precisely near the exit nozzle of the hopper, and in addition the sand can be removed by nerves attached to the axial tube of air conduction, which can be given a rotation movement .
