Machine pour l'extraction d'un câble (32) en matière métallique d'un flanc (2a) d'un pneumatique, qui comprend: un crochet (6) d'extraction dudit câble du flanc (2a) du pneumatique; des moyens (7) de manutention dudit crochet, configurés pour permettre la manipulation du crochet par rapport au bâti dans une direction (D1) d'extraction entre une position (PI) d'engagement avec ledit pneumatique au niveau de la zone de chargement (30) et une position de dégagement à partir dudit pneumatique et d'extraction dudit câble; un élément mobile par rapport au bâti (3) pour effectuer le détachement du câble du crochet (6) quand le crochet est dans ladite position (P2) de dégagement et des moyens de manutention de l'élément mobile.
摘要:
Molds for injection molding tire components have controlled temperature passages leading to a manifold (40) surrounding each mold cavity (16). The manifold (40) is positioned to minimize weld lines in the injected tire component (18). In addition, a narrow gate opening (42, 44, 46) between the manifold (40) and mold cavity (16) provides an elevated temperature of the injected material for decreasing the curing time of the tire component in the mold. Blade members (48) may support and position tire components (50) such as bead apex assemblies in the mold. These tire components (18) may be unloaded by an unloader ring (172) in communication with a source of vacuum for pulling the tire component out of the mold.

摘要:
A method of manufacturing a tire bead core assembly, a tire bead core assembly forming apparatus, a tire bead core assembly, a tire, a bead filler intermediate and a use of a compression mould The invention relates to a method of manufacturing a tire bead core assembly having a bead core and a bead filler. The method comprises the step of placing a bead core (5) in the compression mould. The method also comprises the step of placing a bead filler intermediate in the compression mould. Further, the method comprises the step of pressing the bead filler intermediate onto the bead core using the compression mould. It is noted that the step of pressing the bead filler intermediate (3) onto the bead core may comprise the step of trans¬ forming the bead filler intermediate into a bead filler.
