A workpiece is transported using a porous belt, which belt delivers a workpiece to a chuck, upon which the workpiece is held by vacuum. The belt can be porous PTFE. A flexible stamp is preheated, before it is applied to a workpiece, by drawing the stamp toward a heated plate, for instance by vacuum. Une pièce à travailler est transportée à l'aide d'une courroie poreuse, qui remet la pièce à travailler à un mandrin, sur lequel ladite pièce à travailler est maintenue sous l'effet du vide. La courroie peut être constituée de PTFE poreux. Avant d'être appliqué sur la pièce à travailler, un tampon souple est préchauffé grâce à un déplacement vers une plaque chauffée, par exemple sous l'effet du vide.
