A plug assist assembly for positioning a thermo-formable sheet onto one of a plurality of different female molds. The assembly comprises a lifting apparatus and a frame. The frame extends from the lifting apparatus which provides for beneficial movement of the frame. A plurality of movable weights are suspended from the frame for contacting and automatically conforming to a contour of any of the female molds. The plurality of weights create a seal between the sheet and the female mold to allow the sheet to be vacuum formed against the mold.
L'invention concerne un ensemble poinçon de pré-étirage servant à positionner une feuille thermoformable sur l'une des multiples matrices profilées différentes. L'ensemble comprend un dispositif de levage et un cadre. Le cadre s'étend à partir du dispositif de levage, qui assure un déplacement avantageux du cadre. Une pluralité de poids mobiles sont suspendus au cadre de manière à toucher et à s'adapter automatiquement au profil de n'importe quel moule. La pluralité de poids produit une étanchéité entre la feuille et le moule pour permettre de former sous vide la feuille contre le moule.
