Apparatus for making textured bricks

摘要

Apparatus for making extruded bricks having a textured handmade appearing face designed to form the outer building wall surface, comprising a brick extruding die including a progressively narrowing inlet funnel portion having a downstream end and a constricted neck portion forming a material shaping die throat to receive a column of brick forming clay mix and shape the clay mix column to a rectangular cross-section whose width dimension perpendicular to said face slightly exceeds the desired brick width. A subsurface disrupting elongated thin bridge member transversely spans the die throat and is supplied with liquid under pressure to produce downstream directed liquid jets internally disrupting the clay mix column in the die throat immediately below the upper boundry surface thereof along a substantially horizontal disruption plane. Devices are provided with structure downstream of the die throat for plowing off the uppermost strata of the clay mix column to the level of said disruption plane to expose the disrupted zone and form the textured handmade appearing face and for slicing the exiting column into discete bricks.
