Abstract
Un elemento di filtraggio cilindrico di metallo è collegato ad un coperchio di estremità di materia plastica mediante un'operazione di riscaldamento. Ciò permette che l'elemento di filtraggio così formato sia riciclato e elimina i problemi che si incontrano nella saldatura di coperchi di estremità metallici a mezzi filtranti metallici cilindrici. La connessione può avvenire in presenza di una atmosfera inerte o riducente.(Figura 1).
