CA 2250773

An automotive trim panel (10) is made by using an apparatus and method that bond together two trim coverstock segments (12, 20) having different colors, gauges or textures and two rigid substrate components (30, 32) into a single trim panel with the two coverstock segments meeting along a finished joint line (40). The method includes joining the coverstock segments together to form a rough seam (28), supporting the substrate components on two spaced- apart movable mold components (52, 54) with each substrate component having a mating flange (34, 36) that extends into the space between the mold components, the substrate components arranged such that the rough seam lies midway between the spaced-apart mold components. Pressure is then applied along the rough seam to infold the coverstock between the mold components while moving the mold components toward a clamped position that sandwiches the infolded coverstock portion between the substrate mating flanges and fastens them together with a pre-mounted fastener (44).

Cette invention concerne un panneau de garnissage automobile (10) que l'on fabrique au moyen d'un appareil et selon un procédé permettant d'assembler deux segments (12, 20) de matériau de couverture de couleurs, calibres et textures différents et deux composants de substrat rigide (30, 32) en un seul panneau de garnissage de façon à ce que les deux segments de matériau de couverture soient assemblés le long d'une ligne de joint finie (40). Ledit procédé consiste à assembler les segments de matériau de couverture de façon à constituer un joint grossier (28), à faire reposer les composants du substrat sur deux composants de moule (52, 54) mobiles et espacés l'un de l'autre, chaque composant du substrat possédant une bride d'accouplement (34, 36) qui dépasse à l'intérieur de l'espace existant entre les deux composants de moule et les composants du substrat étant disposés de façon à ce que le joint grossier soit situé à mi-chemin entre les deux composants de moule espacés. On applique alors une pression le long du joint grossier de manière à replier vers l'intérieur le matériau de couverture entre les composants de moule tout en déplaçant ces composants en direction d'une position de blocage où ces composants prennent en sandwich la partie du matériau de couverture repliée entre les bords d'accouplement du substrat et la fixent à ces bords au moyen d'un organe de fixation pré-installé (44).
