AN APPARATUS FOR IMPARTING INDENTATIONS IN A SLUG FROM WHICH SIMULATED GREEN TUMBLED BRICKS ARE FORMED

摘要

An apparatus (1) for imparting indentations in a slug (3) from which green bricks are formed. The slug (3) is elongate about a longitudinal axis and rectangular in transverse cross section to thereby provide a first and second side face extending parallel to the longitudinal axis, a top face (9) and a bottom face. The first and second side face intersect with the top face (9) at a first and second edge, respectively. The apparatus (1) includes a conveyance assembly (25) for conveying the slug (3) in a working direction parallel to the longitudinal axis, and a first and second indentation assembly (29), (31) adjacent to the conveyance assembly (26) for imparting indentations to the first and second edge of the slug (3), respectively. The apparatus (3) further includes a third indentation assembly (45) for imparting indentations to the top face (9) of the slug (3); and control means for controlling operation of the conveyance assembly (25) and the first, second and third indentation assembly (29), (31), (45). The indentations imparted to the top face (9) of the slug (3) are aligned with the indentations imparted to the first and second edge.
