MA-5162-ENG PISTON ADHESIVE MELTER INSTALLATION
3-15
The vibratory element (pneumatic) keeps the adhesive loose around the
entrance to facilitate its suction.
The aspiration element uses compressed air. By the help of the venturi effect,
a depression is created in it, that absorbs pearled and pallet adhesive and
drives it to the shell of the hot-melt system.
The Venturi effect, applied to the vacuum feeder, consists in a decrease of the
air pressure by an air flow inside the closed circuit while increasing the air
speed when passing through the narrowing of the entry mouth.
As the entry of aspiration is connected to this point, the aspired adhesive stays
in it and is transported to the hot-melt tank through the flexible communica-
tion hose.
