Patent

CA 2587377

Thermoforming of plastic sheets over a model includes varying the thickness in the area that is stretched over the model so that when it thins it becomes more uniform in thickness. The plastic sheet is fabricated in a substantially uniform thickness but with a preformed a complex profile or 3D area that partially builds in part of the area that would be stretched so that it thins much less than a flat sheet. Combinations of these elements may also be made.

L~invention concerne un procédé de thermoformage de feuilles plastiques sur un modèle, dans lequel on fait varier l~épaisseur de la feuille dans la zone qui est étirée sur le modèle, de sorte que lorsque ladite feuille s~amincit, son épaisseur devient plus uniforme. La feuille plastique est fabriquée avec une épaisseur sensiblement uniforme, mais avec un profil complexe ou zone 3D préformé qui se forme partielle dans une partie de la zone qui doit être étirée, de sorte que cette feuille s~amincit beaucoup moins qu~une feuille plate. On peut également avoir recours à des combinaisons de ces éléments.
