And the melted resin which is extruded through the die 3 so as to have a desired shape is passed through a calibrator and a cooling device 5.
  • the calibrator 4 allows the profile P passed through the die 3 to maintain its external appearance and have precise demensions and shapes. Therefore, it is preferable that the calibrator 4 is disposed to be adjacent to the die 3 so that the profile passed through the die 3 can be entered into the calibrator 4 without deformation of its shape.
  • a product passed through the calibrator 4 is cooled by the cooling device 5, drawn by predetermined force through a haul-off device 6 and then cut into a desired size by a cutting device.

As a result, a repetition period of the patterns which are repeatedly formed on the surface of the profile becomes short, and thus the graphicness thereof is deteriorated.
  • An object of the present invention is to improve a passage of an auxiliary co-extruding apparatus for forming a skin layer, which is provided in an apparatus for manufacturing a window profile which can provide the texture of natural wood and thus a luxurious atmosphere.
  • the present invention provides an auxiliary co-extruding apparatus 100 for a window profile, in which a co-extrusion resin composition is pressurized and transferred to one side of a die 30 so as to form a skin layer S on a surface of a profile P when a resin material for forming the profile P is melted in a main extruder 10 and then pressurized and trasferred to the die, characterized in that the auxiliary co-extruding apparatus comprises a connector 10 for vertically changing a running direction of the co-extrusion resin composition, and a curved portion 113, 114 which smoothly changes the running direction of the resin composition is formed between an inlet port 111 and a outlet port 112 of the connector.

  • the apparatus further includes a calibrator 70 which maintains an external appearance of the profile discharged from the die, and a cooling device 90 which cools the profile passed through the calibrator.
  • the co-extrusion resin composition contains wood fiber.
  • the skin layer is integrally foremd with one side of the profile by the co-extrusion, and thus it is possible to provide the texture of natural wood and thus a luxurious atmosphere. Further, since the present invention provides the improved passgae of the auxiliary co-extruding apparatus in order to prevent the resin composition therein from being carbonized and also prevent the excessive energy consumption in transferring the resin composition, it is possible to enhance the graphicness of the patterns formed on the skin layer of the profile.

  • the calibrator 70 is disposed to be adjacent to the die so that the profile passed through the die can be entered into the calibrator 70 without deformation of its shape, and a surface cooling process of the profile P is performed before the profile P is entered into the calibrator 70. If the profile P is immediately entered into the calibrator without the surface cooling thereof, there may be a problem that embo-patterns formed on a surface of the profile is worn and disappear by surface friction between the molded resin of the profile and an internal metal of the calibrator. Therefore, it is preferable that air is used as a cooling medium. That is, in the surface cooling device, air is uniformly injected on the profile so that the surface of the profile is rapidly cooled.

  • ths skin layer By forming ths skin layer using the co-extrusion, it is possible to provide various colors using various materials for the skin layer. Since a different material from that of the profile is integrally formed with the profile through the co-extrusion, a post process like attaching of a sheet is not needed after production of the profile. Also, it is posssible to reduce manufacturing cost and also enhance workability of the product. Further, since an adhesive is not used, it is environmentally friendly, and also it is advantageous against scratches.
  • the co-extrusion resin composition forming the skin layer S contains wood fiber, thereby improving the texture of natural wood and thus graphicness thereof.

  • the second second raw material for forming a mid-tone color is composed of a resin such highly polymerized PVC, ASA, PMMA and PE which has a higher melting point than the fisrt raw material (base material), a small amount of inorganic mid-tone pigment having excellent weather resistance, a small amount of an additive such as a lubricant, and the like.
  • the third raw material for forming a high-tone color is composed of a resin such highly polymerized PVC, ASA, PMMA and PE which has a higher melting point than the fisrt raw material (base material), a small amount of inorganic high-tone pigment having excellent weather resistance, a small amount of an additive such as a lubricant, and the like.
  • the first, second and third raw materials are not mixed in order to form one color. But in a state that the skin layer is formed on the profile, the second and third raw materials respectively show a mid tone color and a high tone color on the first raw material as the base material so that each color can be distinguished from each other, thereby providing natural colors having excellent graphicness.

If the melting points of the resin compositions are all the same, all of the resin compositions are melted and mixed together in the auxiliary co-extruding apparatus 100, and thus each of the colors is not distinguished from each other but changed into one color. Therefore, to prevent such phenomenon, each melting point is different from each other.

Further, since the present invention provides the improved passgae of the auxiliary co-extruding apparatus in order to prevent the resin composition therein from being carbonized and also prevent the excessive energy consumption in transferring the resin composition, it is possible to enhance the graphicness of the patterns formed on the skin layer of the profile.

Abstract

L'invention concerne une co-extrudeuse auxiliaire (100) pour un profil de fenêtre. La co-extrudeuse auxiliaire (100) pour un profil de fenêtre dans laquelle une composition de résine de co-extrusion est mise sous pression puis transférée depuis un côté d'une matrice (30) de manière à former une couche mince (S) sur une surface d'un profil (F) lorsqu'un matériau à base de résine destiné à la formation du profil (P) est mélangé dans une extrudeuse principale (10) puis mis sous pression et transféré vers la matrice, se caractérise en ce que la co-extrudeuse auxiliaire comprend un raccord (10) pour modifier verticalement un sens de déplacement de la composition de résine de co-extrusion, et une partie incurvée (113, 114) modifiant sans à-coups le sens de déplacement de la composition de résine est formée entre un orifice d'amenée (111) et un orifice de sortie (112) du raccord. Le mode de réalisation de l'invention permet d'obtenir un passage amélioré de la co-extrudeuse auxiliaire afin d'empêcher la composition de résine d'être carbonisée et afin d'empêcher une consommation d'énergie excessive lors du transfert de la composition de résine: il est également possible d'améliorer l'aspect graphique des motifs formés sur la couche mince du profil.
