Abstract

Equipo para formar en un tubo metálico de diámetro prefijado un trecho terminal de un diámetro infrior a aquel diámetro prefijado, caracterizado porqeu comprende una hilera adecuada para ser atravesada por el referido extremo del tubo a fin de formar el citado trecho y provista de un primer orificio sensiblemente cilíndrico de diámetro inferior al de dicho tubo de un segundo orificio coaxial respecto al anterior sensiblemente cónico y cuyo diámetro mínimo coincide con el del primer orificio mencionado y cuyo diámetro máximo es superior al citado diámetro del tubo y por lo menos de tres cuepros rotativos dispuestos en correspondientes asientos de la mencionada hilera practicados en la zona del segundo orificio mencionado sobresaliendo cada uno de tales cuerpos radialmente en una medida prefijada respecto a la superficie del segundo orificio hacia el eje del mismo y medios de arrastre adecuados para desplazar axialmente dicha hilera respecto al citado tubo de modo que se lleve el referido extremo de éste al interior del primer y segundo orificios y que coopere con dichos cuerpos rotatorios.
