<p>The procedure consists of using an oscillating cutting disc (6) with a flat cutting edge to cut a sheet of fibre-reinforced concrete (1) laid with its finish face upwards on two supports (5, 5'). The cutting disc is able to rotate freely and is positioned so that its side faces are between 2 and 20 mm, and preferably 3 - 8 mm, from the two supports, which have flat thrust surfaces.</p> |
