Claims5
A color blending apparatus for blending different colored semi-dry concrete mixes together, and for delivering the different colored semi-dry concrete mixes to a mold from a feedbox, the feedbox moving over the mold in a reference direction, the apparatus comprising:
- a conveyor for receiving two or more different colored semi-dry concrete mixes, the semi-dry concrete mixes received in a controllably variable position with respect to each other, the conveyor capable of movement in a first direction to advance the two or more different colored semi-dry concrete mixes, and a second direction generally transverse to the first direction;
- and
- a face mix hopper having a top portion for receiving the two or more different colored semi-dry concrete mixes, the conveyor capable of movement in the second direction to convey the two or more different colored semi-dry concrete mixes into the top portion across a width of the face mix hopper, the conveyor capable of depositing each of two or more colored semi-dry concrete mixes from the conveyor to different lateral positions across the width of the face mix hopper.
