PROCESS AND DEVICE FOR COATING WITH A SUSPENSION THE INSIDE OF MEANDROUS ONE-TUBE GLASS VESSELS

摘要

A process and device are disclosed for coating with a suspension the inside of meandrous onetube glass vessels (4). After the introduction of a dosed amount of a suspension, an axially rotating meandrous one-tube glass vessel (4) moves horizontally and is tilted, so that the legs of the one-tube glass vessel (4) take a horizontal position between the reversal points of the tilting movement. The object of the invention is in particular to allow the inside of meandrous one-tube glass vessels (4) to be coated with a suspension of luminescent material for compact lamps.
