Abstract

Aparato para formar aletas en tubos metálicos por un procedimiento de laminación, comprendiendo: un mandril flotante colocado en el interior de un tubo, mandril que tiene partes extremas de diámetro escalonados unidas entre sí por una parte cónica intermedia; una pluralidad de rodillos reductores en contacto con la periferia del tubo en una zona opuesta a la parte cónica de dicho mandril y adaptados para reducir el diámetro interior del tubo a un valor inferior al del diámetro del extremo mayor de dicho mandril; una pluralidad de rodillos formadores de aletas en contacto con la periferia del tubo después de la reducción del diámetro de éste efectuada por los rodillos reductores anteriores y en una zona opuesta al extremo de menor diámetro de dicho mandril; y un sistema para producir la rotación relativa entre el tubo y los anteriores rodillos.
