<p>The invention relates to a unit for format cutting,especially of a format basically on height from rectagular bodiessuch as bricks or panels, or belts (beams) of hard rectagularmaterial wich has not been completely hardened, preferably lyingon its wide side on a cuting seat, porous concrete block having acutting device. It consists of a cutting frame moving from bottomto top or from top to bottom and having cutting strings positionedat prespecified distances, parallel to each otehr, and of a fixedseat for cutting having supporting members positioned parallellyto the cutting strings of the frame, spaced by intermediate gaps.The porous concrete block subject to cutting lies on theirsupporting surface, and between tem, to their widths respectively,lie the lowered grating elements of a grid. The cutting seat (1)has supporting elements (12, 13) having different widths of theirsupporting surfaces which are spaced from each other by means ofdifferent space distances (15, 16) in the zone of the supportingsurface in such a manner that when the cut bodies of differentformat heights are supported by at least two cross bars (8, 8a) ofthe grid (7) when being lifted from the cutting seat (1) by meansof the grating grid (7).</p> |
