Zusammenfassung: | An apparatus for forming an interior panel for a vehicule door includes mandrels (100) which hold rolls of vinyl laminate (44) and fiberglass reinforcing mat (42) and from which sheets of vinyl laminate (43) and reinforcing mat (41) are pulled in overlying relation with respect to each other. The vinyl and mat sheets (43, 41) are tacked together, cut to a predetermined length by a cutting mechanism (48), and moved into a heater (56) by a pin-chain conveyor system (50). In the heater (56), the vinyl (43) and mat (41) are heated until the vinyl (43), which is supported at its edges by the pin-chain conveyor (50), sags a sufficient amount to indicate that the vinyl (43) is sufficiently softened. The heated vinyl (43) and mat (41) are then moved to a vacuum mold part (86) and thereafter a vacuum is applied to draw the vinyl (43) to a molding surface of the vacuum mold part (120). A vacuum assist, carried on a carrier (84), engages the mat (41) and heated vinyl (43) within the vacuum mold part (86) to press the mat (41) into the heated vinyl (43) to partially embed the mat (41) into the vinyl (43) to secure the mat to the vinyl (43). Thereafter, a foamable and curable urethane substrate material is poured into the formed vinyl and mat (83). A cooperating opposed mold part (88) engages the vacuum mold part (86) and applies heat and pressure to form the urethane substrate material and to cure the substrate material into a relatively rigid substrate which is reinforced by the mat (41).
L'invention concerne un dispositif permettant de former le panneau intérieur d'une portière de véhicule, qui comprend des mandrins (100) supportant des rouleaux constitués d'un stratifié vinylique (44) et d'un mat de renforcement (41) en fibres de verre, depuis lesquels des feuilles constituées d'un stratifié vinylique (43) et d'un mat de renforcement (41) sont tirées superposées l'une à l'autre. Les feuilles constituées de vinyle et de mat (43, 41) sont collées ensemble, coupées à une longueur prédéfinie par un mécanisme de coupe (48) et amenées dans un élément chauffant (56) par un système de transporteur à chaîne à picots (50). Dans l'élément chauffant (56), le vinyle (43) et le mat (41) sont chauffés jusqu'à ce que le vinyle (43), qui est supporté au niveau de ses bords par le transporteur (50), s'abaisse suffisamment pour indiquer qu'il est suffisamment ramolli. Le vinyle chauffé (43) et le mat (41) sont ensuite amenés à un élément moule pour moulage sous vide (86), puis une as |
