ABSTRACT:
The apparatus for removing the waste layer arising in cutting porous concrete blocks comprises a beam (1) which extends above the porous concrete block in its longitudinal direction and can be raised and lowered, and at least two horizontal support frames (2, 2') mounted thereon and movable in height, which are arranged in pairs opposite one another to the two sides of a vertical central plane (M) of the beam (1) and beneath the same. A plurality of spikes (5, 5') which can be stuck into the waste layer are provided on the underside of each support frame (2, 2') and are aligned with their points facing down at an angle. All spikes (5) of the first support frame (2) of each frame pair (P) are parallel to one another and inclined at an acute angle (.mu.) to the longitudinal central plane (M) and all spikes (5') of the opposite second support frame (2') are parallel to one another and inclined at an opposite acute angle (.mu.l) to the longitudinal central plane (M). Each support frame (2, 2') is movable relative to the beam in the direction (B or C) of its spikes (5, 5').
