Abstract

Sacchetto filtrante (1, 9), del tipo comprendente almeno due fogli esterni impermeabili in materiale plastico (2, 3), resi solidali l'uno all'altro su almeno parte del loro perimetro in modo da formare una tasca, ed un elemento filtrante (4, 14) in orma di foglio che si estende all'interno della tasca in modo da definire due comparti (V1, V2) separati dal detto elemento filtrante (4, 14), l'elemento filtrante (4, 14) essendo costituito da una pellicola permeabile della quale almeno parte del perimetro è fissato ad uno dei detti fogli (2, 3), allo scopo di definire con quest'ultimo un comparto aperto dalla stessa parte della detta tasca.Procedimento per la realizzazione di un sacchetto filtrante come sopra descritto, prevedente di svolgere tre bande (6, 7, 8), ed in particolare due bande esterne (6, 7) in materiale impermeabile ed una banda centrale (8) in materiale permeabile poroso fino a sovrapporle e di effettuare, ad ognuno dei passi, un'operazione di saldatura realizzando contemporaneamente tutte le saldature del sacchetto filtrante (1).Filter bag (1, 9), of the type comprising at least two waterproof external sheets of plastic material (2, 3), made integral with each other on at least part of their perimeter so as to form a pocket, and a filter element (4, 14) in foil form which extends inside the pocket so as to define two compartments (V1, V2) separated from said filter element (4, 14), the filter element (4, 14) being constituted by a permeable film of which at least part of the perimeter is fixed to one of the said sheets (2, 3), in order to define with the latter a compartment opened on the same part of the said pocket. Procedure for the realization of a filter bag as described above, comprising three bands (6, 7, 8), and in particular two external bands (6, 7) in impermeable material and a central band (8) in permeable porous material up to overlap and carrying out, each one of the steps, a welding operation realizing contemp all the welds of the filter bag (1).
