Beschreibung
Zusammenfassung:	A thermoforming apparatus and a method of manufacturing a fiber-based tray. The thermoforming apparatus having a male and a female portion. The male portion having a protruding section and a secondary protrusion which contacts a compressed fiber web of unwoven fiber material prior to the remaining portions of the protruding section. Advancement mechanisms retract the secondary protrusion such that the male and female portions compress the fiber web to thermoform a tray. L'invention concerne un appareil de thermoformage et un procédé de fabrication d'un plateau à base de fibres. L'appareil de thermoformage comporte une partie mâle et une partie femelle. La partie mâle comporte une section saillante et une saillie secondaire qui entre en contact avec une bande de fibres comprimées de matériau en fibres non tissées avant les parties restantes de la section en saillie. Des mécanismes d'avancement rétractent la saillie secondaire de telle sorte que les parties mâle et femelle compriment la bande de fibres pour thermoformer un plateau.
