An apparatus for producing patterned molded articles includes an injection mold assembly composed of first and second molds, a roll for unwinding a continuity of a pattern film, a film introducing device for introducing the pattern film into a location between the first mold and the second mold. A main clamp presses the pattern film against a surface of the first mold. The apparatus further has a cutter on the upstream side of the surface of the first mold, serving for cutting off the pattern film. A sub-clamp on the downstream side of the surface of the first mold serves for fixing a cut-off end portion of the pattern film. The film introducing device has a pinch device for grasping the cut-off end portion of the pattern film and a device for reciprocatingly moving the pinch device.
Un dispositif de moulage comprend un moule d'injection (1) comprenant une première matrice (A) et une seconde matrice (B), un organe (2) destiné à dérouler une longueur de film (7) présentant des motifs, un organe (3) destiné à introduire, entre la première matrice (A) et la seconde matrice (B), le film (7) déroulé par l'organe (2), un organe principal de fixation (4) conçu pour presser le film (7) contre la surface de la première matrice (A), un organe (5) destiné à couper le film (7), monté en amont de la surface de la première matrice (A), un organe secondaire de fixation (6) conçu pour fixer une extrémité coupée (70) du film (7) et monté en aval de la surface de la première matrice (A). L'organe d'introduction (3) du film est muni d'une pince (30) permettant de saisir l'extrémité coupée (70) du film (7) et d'un organe d'actionnement (31) destiné à animer la pince d'un mouvement de va-et-vient.
