Abstract

Una parte dilatata (59) viene formata su di una lamina metallica (55) così che un foro passante (60) viene formato sulla superficie di estremità anteriore di questa parte dilatata (59), e successivamente una parte di estremità anteriore (72) della parte dilatata (59) viene relativamente ridotta nel diametro esterno in confronto con una parte di base (73), così che la parte di estremità anteriore (72) viene relativamente ridotta nello spessore. Poi, i diametri esterno ed interno della parte di base (72) vengono ridotti mantenendo sostanzialmente il loro spessore. Quindi, la parte di estremità anteriore (72) definisce una parte relativamente sottile (34) da presellare, e la parte di base (73) definisce una parte (35) relativamente spessa formante una madrevite. Quindi, è possibile formare una parte ad albero (32) avente un diametro esterno uniforme e comprendente la parte (34) da presellare ponendo la relativamente sottile parte di estremità anteriore (72) per un dado a T in uno stato tenuto dalla lamina metallica (55), con applicazione di lavorazione plastica.
