B28B13/023 - CPC Classification

Classification description:

Feeding the unshaped material to moulds or apparatus for producing shaped articles; Discharging shaped articles from such moulds or apparatus; Feeding the unshaped material to moulds or apparatus for producing shaped articles; Feeding the moulding material in measured quantities from a container or silo by using a feed box transferring the moulding material from a hopper to the moulding cavities

Sub-classes:

B28B13/0235 » {the feed box being provided with agitating means, e.g. stirring vanes to avoid premature setting of the moulding material } 7
B28B13/0245 » {Rotatable feed frames, e.g. horizontally rotated over 90 degrees} 7
B28B13/025 » {the feed box being vibrated, e.g. to promote discharging of the material} 4
B28B13/0255 » {Disposal of residual material, e.g. by means of the return stroke of the feed drawer} 2
B28B2013/024 » {the feed box being provided with means for transporting the moulded products, e.g. out of the machine} 2
