Abstract

Método para unir los aros de refuerzo de los talones a una armazón de neumático en construcción según el procedimiento que prevé envolver las telas de armazón alrededor a un tambor de confección de tipo expansible predispuesto en forma cilíndrica, de centrar dichos aros en un plano normal al eje de dicho tambor de confección, en posición a éste coaxial, de bloquear dicho aro axialmente por ambas partes en dicha posición centrada, mediante un dispositivo de cerraje con pinzas, axialmente desplazable, de calzar los aros en dicho cilindro, mediante desplazamiento axial de dicho dispositivo, en una posición prefijada a lo largo del desarrollo longitudinal del tambor hasta presionarlas contra la superficie Radialmente interna de dichos aros, alejando luego dicho dispositivo de cerraje y prosiguiendo luego la expansión de dicho tambor con consiguiente rehinchamiento de las telas de armazón a los lados del aro hasta sobrepujar radialmente este último.
