A machine for simultaneous filling of a plurality of tubular electrical resistance elements comprises means (26) for holding of a plurality of element tubes (17) in a vertical position, support means (29) for supporting the lowermost ends of the element tubes (17) and simultaneously therewith holding the lowermost terminal end of the resistance wire spiral, hooking means for hooking up the uppermost terminal end of the resistance wire, means (14) for holding filling tubes (15) which surround one resistance wire spiral each. An insulation powder magazine (19) is disposed laterally adjacent the filling tubes (15) and feeds the element tubes (17) with insulating powder through filling hoppers (21) which are vertically movable and are fed with predetermined amounts of insulating powder through longitudinally retractable and extendable obliquely downwardly directed tubular nozzles (20). |
