Abstract

L'invenzione riguarda un filtro (5) per filtro-pressa (1), di cui fa parte un elemento centrale (8) costituito da una striscia (9) sostanzialmente rettangolare realizzata in materiale termoplastico, avvolta in forma di cilindro cavo e presentante due propri bordi (9') opposti reciprocamente saldati; le porzioni (11) di estremità assialmente opposte dell'elemento centrale (8) sono radialmente ripiegate verso l'esterno dell'elemento centrale (8) stesso e definiscono, ciascuna, almeno con una propria parte, un bordo (12) di collegamento presentante sostanzialmente la forma di una corona circolare e giacente su di una superficie sostanzialmente piana e normale all'asse longitudinale dell'elemento centrale (8), e del filtro (5) fanno parte due elementi anulari (14) realizzati in materiale termoplastico ed aventi sostanzialmente la forma di una corona circolare, saldati a rispettivi bordi (12) di collegamento e collegati a rispettivi fogli (7) di materiale filtrante dotati, ciascuno, di un foro (15) circolare coassiale all'elemento centrale (8).(FIG.5)
