<p>The invention relates to a device for the manufacture of a tray (6) of cellulose material, which comprises: a compression mould (3) comprising an essentially flat bottom end (36) and surrounding sides (37); a male mould (2) that is arranged to fit into the compression mould (3), wherein the compression mould (3) and the male mould (2) between themselves delimit a mould space (30). Both the moulds (2, 3) are provided with devices for blowing in and suction of fluid in and out of the mould space (30). The blow and suction devices of both the moulds (2, 3) comprise an inlet pipe (23, 33) and inlet chamber (28, 38), in connection with the mould space (30) and an. outlet pipe (24, 34) and outlet chamber (29, 39), which is separated from the inlet pipe (23, 33) in connection with the mould space (30), whereby fluid that is free from impurities is arranged to be lead into the mould via the respective inlet pipes (23, 33) and the inlet chambers (28, 38), and whereby the fluid from the mould space (30) is arranged to be lead away via the outlet chambers (29, 39) and the outlet pipes (24, 34) without contaminating the respective inlet pipe (23, 33).</p> |
