Abstract
The present invention is concerned with a method of and apparatus for cutting a slab from a body of uncured light-weight concrete, resting on a support surface. The method comprises the step of moving the body of uncured light-weight concrete along a longitudinal axis of said support surface through a predetermined distance; cutting a slab from said body while supporting the front face of said slab, moving the slab away from said body along an extension of said longitudinal axis; and subsequently moving the slab along at least one arcuate movement path in a plane perpendicular to said support surface and parallel to said longitudinal axis. The apparatus for performing the methods includes a sequentially moveable work feed means, a wire cutter mechanism for cutting a slab from the face of the concrete and a carosel-like pneumatic suction device for holding and transporting the cut slab to subsequent spraying, shaping and stacking stations.
