Abstract
Cellular lightweight concrete slabs are manufactured by cutting horizontally through a block of still plastic cellular concrete mass resting on a support. At each cut a single slice is separated from the lowermost portion of the block or the remainder thereof. After each completed cut the upper remainder of the block is elevated by means of a suction head, in order to expose the recently cut surfaces for a treatment, and then again deposited on top of the slice or slices already resting on the support. Rotary roller means are provided for contributing in the surface treatment.
