ABSTRACT:
This invention provides an improved method and an improved apparatus for cutting bitumen cakes or like products from a sheet of the product previously cast in a flat-bottomed basin, during the cooling of the sheet. The cakes are cut out of strips previously cut out of said sheet. A transverse girder mounted on wheels span the basin, and suspended from the girder is a carriage supporting a pivoted heated cutter. As the cutter moves in the cutting direction it cuts a transverse strip of product and carries along a trolley provided with a wedge member adapted at the same time to raise the cut strip. The carriage also comprises a pusher arm whereby, during the return stroke of said carriage, said pusher arm can drive the fully cut strip towards another cutter of the guillotine type which cuts the cakes out of the strip. During the strip cutting step, the carriage also carries along a belt so as to insert the same under the strip as it is cut by said first cutter.
