Abstract

Appareil à extruder des cordons de matières plastiques telles que des produits de caoutchouc, élasto-plastiques et éventuellement collants ou du mastic, comportant une âme de fil retors enrobée concentriquement dans cordon, à l'aide d'une tête d'extrusion reliée en particulier à une extrudeuse. Dans cet appareil de préférence, dans la sortie 4 de l'extrudeuse 1, la matière est comprimée tout d'abord dans une embouchure se rétrécissant coniquement, à la suite de l'entrée 5 de la tête d'extrusion 2 elle est comprimée davantage dans un canal convenablement profilé 6, et enfin, en passant par une déviation d'écoulement 7, elle est conduite dans une partie d'amenée 10 de préférence conique, débouchant dans la région d'entrée rétrécie concave 8 de la filière 9. La broche 13 comportant une perforation axiale pour le passage de l'âme de fil retors du cordon est guidée et réglable longitudinalement pour que sa pointe arrive dans l'axe de l'entrée concave 8 de la filière. L'invention est applicable notamment à la fabrication de profilés plastiques de bandes de joint à vitres des automobiles.
