<p>The invention concerns an installation cutting out pieces in a sheet material, comprising a cutting table (12) receiving the sheet material (30) from a loading station (12) and a station (16) for unloading cut out pieces. A flexible sealing film (32) is brought onto the sheet material upstream of the cutting table and is applied by causing a depression at the cutting table surface. After cutting, at least a skeleton (32)' of the sealing film is detached at the downstream end of the cutting table to be recovered. The recovery is carried out by automatic winding outside the unloading station, by placing clips on the sealing film astride on the cutting lines, or by suction of fragments of the sealing film using a rotary element pressing on the sheet material.</p> |
