Install hollow-centered dust brush in vinyl plastic housings.
What does a Dust Brush Assembler do?
Installs hollow-centered dust brush in vinyl plastic housing to form vacuum cleaner attachment: Loads plastic housings into tank of warm water to soften plastic material and increase elasticity. Removes warmed housing from water, and places housing in bench fixture. Inserts back of brush in housing, and presses down on brush with fingers to expand heat-softened wall of housing, and force brush into retaining groove. May remove plastic housing from mold while housing is still warm and elastic, and place housing in bench fixture, rather than place housing in warm water to soften.
