Abstract:
1. An assembly for molding and demolding hardened cementitious products comprising: a flexible mold having a top side with separate openings for receiving cementitious material therein for hardening thereof, an opposite closed rear side and a perimeter; and an apparatus for demolding the hardened cementitious products from said flexible mold comprising: a conveyor for conveying said flexible mold with a front face down; a clamp for clamping a portion of said perimeter; a holding member for engaging said mold rear side; a movable member for moving said clamp and said clamped portion of said mold upwardly causing said mold to curve about said holding member thereby disengaging said flexible mold from the cementitious material; and wherein said conveyor comprises an upstream surface and a downstream surface, said downstream surface being slightly lower than said upstream surface so as to provide a space between said perimeter of said mold and said downstream surface thereby allowing for said clamp to engage said perimeter.
