Abstract
When an empty molding box arrives at the molding machine on a roller track extending through the machine, it is placed on a pattern plate carrier with a pattern situated thereon and is lowered thereon on to a transverse roller track on which it is transferred, by means of a thrust drive operating on the carrier, to the empty station of a two-station transporting carriage on which it is then moved, by means of another thrust drive operating on the carriage, to one of the two outer working stations of a three-station roller track, namely a preparation track, parallel to the first-mentioned roller track, where the preparation work is done. As the two-station carriage moves thus, an already prepared molding box and carrier on its other station arrives at the central station of the preparation track and is then drawn back to the molding machine. After the molding operation the pattern plate carrier is extracted for re-use with another empty molding box, while the completed molding box is transferred away along the first-mentioned roller track. Coupling means, comprising plates on the first-mentioned thrust drive and the pattern plate carriers, move into and out of engagement as required when the carrier is moved vertically in the molding machine or horizontally on the preparation track.
