ABSTRACT:
Vaporizers with flat wicks folded into U-shape within open-topped, laterally apertured generally prismatic casings, capped by complementary covers which are vertically slidable thereon to control the escape of a volatile liquid impregnating the wicks, are mass-produced on a plurality of assembly lines each comprising a wick-loading station, an impregnating station, an insertion station and a capping station. The dry and unfolded wicks are successively advanced from their loading station along an upper track past the impregnating station, where they are permeated with the liquid, to the insertion station in which a plunger thrusts each wick through a narrow central slit into an aligned casing waiting on a lower track, the wick being doubled in passing through the slit into the casing. The filled casings travel on the lower track to the capping station where they are fitted with covers as they pass under a flat end of an arcuate tube through which the covers are delivered from a supply chute by an oscillating arm. The several assembly lines terminate at a common turntable from which their vaporizers are discharged to a packaging station.
