Abstract

PURPOSE:To facilitate the work for maintenance, checking and the like by communicating a pressure air passing hole for retraction of piston with a similar hole for inducing and feeding materials by a common feeding hole and thus simplifying the device. CONSTITUTION:In a material-feeding device wherein the cylinder 5 of an air-pressure-type control device 1 whose tip is opened in a molding chamber 4 and a material-feeding pipe 6 whose rear end is communicated with a material hopper are communicated crossingly with each other, the passing hole 8' of the pressure air for backing a piston 13 and the other passing hole 9 of the pressure air for attracting and sending a material W into the molding chamber 4 are made respectively in a peripheral wall 7 and both holes 8' and 9 are communicated with one heated steam feeding hole 8. And, the gate 19 of the hopper 3 being moved in the direction of an arrow A, while the pressure air being passed through the feeding hole 8 and the passing hole 9, the material W is attracted and sent into the molding chamber 4. Next, the piston 13 being moved in the direction of an arrow D, molding under heat is performed, and after that, the pressure air being sent from the passing hole 8', the piston 13 is retracted.
