Claims (4)

1. Förfarande för att förflytta pulverformiga partiklar pä en bana (W) för att bilda ett bestrykningsskikt eller ett filmskikt vid en torrytbe-handlingsprocess, vid vilken de pulverformiga partiklarna fästs pä ett mellanunderlag, frän vilket de befrias tili banan, kännetecknat av, att mellanunderlaget är ett väsentligen isolerande ändlöst band (1), pä vilket de pulverformiga partiklarna fästs med hjälp av elektriska krafter.
2. Förfarande enligt patentkrav 1, kännetecknat av, att bandet (1) är laddat med hjälp av koronaurladdning eller friktionselektricitet.
3. Förfarande enligt patentkrav 1 eller 2, kännetecknat av, att de pulverformiga partiklarna befrias frän bandet (1) genom att rikta elektriska krafter pä bandet (1), vilka krafter försvagar partiklarnas vid-häftning pä bandet (1).
4. Anordning för att bilda ett bestrykningsskikt eller ett filmskikt vid en torrytbehandlingsprocess, vilken anordning omfattar medel för att ladda pulverformiga partiklar elektriskt ooh medel för att förflytta de laddade partiklarna pä en bana (W), varvid anordningen omfattar ett mellanunderlag, pä vars yta de laddade pulverformiga partiklarna är anordnade att fästas innan de förflyttas pä banan, kännetecknad av, att mellanunderlaget är ett väsentligen isolerande ändlöst band (1).
