Abstract

Cette invention concerne une bobine de plastique (50) unitaire, à grande capacité de chargement et d'un faible poids. Cette bobine comprend les éléments suivants: une première (55a) et une seconde (55b) parties latérales comportant des flancs et globalement circulaires; une partie tambour (60) formée entre les parties latérales comportant des flancs; un trou d'arbre central (75) linéaire qui suit l'axe central de la bobine entre les deux parties comportant des flancs; et enfin, plusieurs trous (80) qui partent de chaque partie comportant des flancs, qui s'étendent partiellement jusque dans la partie tambour et qui sont parallèles au trou d'arbre central. Ces trous contribuent à l'obtention d'une structure de faible poids. Cette invention concerne également un moule (100) permettant de former une bobine unitaire, lequel comprend une ouverture d'entrée (110) permettant à un dispositif d'extrusion de matières plastiques de le remplir. Une goupille de moulage (229) centrale et conique est disposée dans le moule et possède une surface supérieure proche de l'ouverture d'entrée, ceci de manière à faciliter la répartition uniforme des matières plastiques provenant du dispositif d'extrusion dans toutes les parties dudit moule.
