Abstract
Det er tilveiebrakt en innretning for elektrostatisk belegning av en far- masøytisk tablettkjerne med pulverformet belegningsmateriale. Innretningen om- fatter en første roterende trommel (12) på hvilken en kjerne holdes i elektrisk isolasjon fra sine omgivelser, men på en potensialforskjell i forhold til jord ved hjelp av en elektrode som kontakter kjernen. Kjernen føres forbi en beleg- ningsstasjon (B) på hvilken pulverpar- tikler som har en motsatt potensialfor- skjell i forhold til Jord, holdes i et trau (18). Trommelens overflate holdes på den samme potensialforskjell i for- hold til jord som pulverpartiklene. Pulveret tiltrekkes til kjernen, og ikke til trommelen, slik at den avdekkede overflate av kjernen belegges. Trommelen medbringer den belagte kjerne forbi en smeltestasjon (C) på hvilken et varme- legeme smelter pulveret for å danne et kontinuerlig filmbelegg. Deretter vendes kjernen og overføres til en andre trom- mel (12' ) hvor den andre overflate be- legges på samme måte.
