A porous support intended to be removably positioned on a top side of a perforated plate of a table of a vacuum hold down device, the perforated plate having a bottom side connected to a vacuum system for producing reduced pressure on the bottom side, wherein the porous support comprises a perforated tray provided on a first side with outer reliefs and on a second side with a blade penetrable porous structure fixed thereon.
A vacuum hold down device comprising:
- a table comprising a perforated plate having a bottom side connected to a vacuum system for producing reduced pressure on the bottom side, and
- at least a porous support removably positioned on a top side of the perforated plate of the table, wherein the porous support comprises a perforated tray provided on a first side with outer reliefs and on a second side with a blade penetrable porous structure fixed thereon.
A process for replacing a first porous support positioned on a perforated plate of a vacuum hold down device by a second porous support, comprising the following steps:
- i) removing the first porous support, and
- ii) positioning the second porous support on a top side of the perforated plate, with outer reliefs of a perforated tray of the second porous support facing the top side of the perforated plate.
