Abstract

Cabeza de tobera de extrusión, preferentemente cabeza de soplado de láminas, con un canal central con forma de anillo (1), que está provisto de una tobera de salida con forma de anillo (19) y en cuya pared exterior de limitación desembocan hendiduras anulares con forma de anillo, que conducen una masa fundida de material plástico y que son desembocaduras de diámetro más pequeño de los canales (12) con forma de tronco cónico, que están formados entre las superficies de envoltura interior y exterior de piezas suplementarias encajables con forma cónica (5, 10, 11, 23, 24) apiladas unas sobre otras, caracterizada porque también en la pared interior del canal central con forma de anillo (1) desembocan hendiduras anulares que conducen masas fundidas de material plástico, que son las desembocaduras de diámetro más grande de los canales (13) con forma de tronco cónico, que están formados entre las superficies de envoltura interior y exterior de piezas suplementarias encajables (4, 8, 9, 21, 22) conforma cónica apiladas unas sobre otras, y porque en cada una de las superficies interior o exterior de envoltura de las piezas suplementarias encajables con forma cónica están realizados respectivamente dos canales (6) con forma de espiral en sentidos opuestos entre sí, con una profundidad que va disminuyendo hacia la desembocadura.
