摘要 |
A powder applicator for applying powder to form side stripes on the interior of can bodies B along side seams thereof includes a device for providing a layering effect on the gas-entrained powder so that although the powder is normally carried by the gaseous stream it is directed into an orifice 24 of a nozzle 21 as a dense stream with the carrier gas forming a separate layer. This separation takes place centrifugally in a loop 22 in the supply conduit 17. In addition, the applicator forms a seal with the interior of the can body to define a limited sealed area within which the powder may pass. This sealed area contains corona charging pins 41 which are arranged in a longitudinal line so that a maximum charging of the powder may be effected. Also, a diffused gas is directed into the sealed area to prevent the powder from clinging to the side walls of the sealed area and the charging pins. <IMAGE> |
