<p>Pieces are cut out from a sheet material by means of an installation comprising a cutting-out table ( 12 ) receiving the sheet material ( 30 ) from a loading station ( 12 ), and an unloading station ( 16 ) for unloading cut-out pieces. A flexible sealing film ( 32 ) is brought onto the sheet material upstream from the cutting-out table, and it is applied by establishing suction at the surface of the cutting-out table. After cutting-out, at least the skeleton ( 32' ) of the sealing film is separated at the downstream end of the cutting-out table in order to be recovered. The recovery is preformed by automatic winding-up outside the unloading station, it being possible to deposit fastenings on the sealing film so that they straddle the cutting-out lines, or else said recovery is performed by sucking up the fragments of sealing film by means of a rotary member bearing against the sheet material.</p> |
