• Allow machine to cool and adhesive to solidify before attempting to move the machine.
• A qualified electrician or appliance repair person should perform machine repair.
• Do not overfill adhesive pot. Molten adhesive should never be above the

Description of Machine
The Hysol
®
Wheel Coater (98038) is a bulk hot melt adhesive transfer machine. The Hysol
®
Wheel Coater is used to apply a continuous film of hot melt adhesive to the surface of a part.
The Wheel Coater is made up of an adhesive reservoir (6.5" wide x 10" long x 2" deep), three
350-watt heaters and a transfer roller, which is driven by a variable speed electric motor. The
thickness of the adhesive film is fully adjustable and a thermometer is used to indicate reservoir
temperature. The variable speed motor and film thickness control greatly contributes to increase
productivity of hot melt adhesive applications.
2.2
Theory of Operation
The adhesive is applied by passing the surface of the part over a rotating roller. A thin film of
adhesive is transferred from the roller to the part. The roller is six inches in length and is partially
submerged in a pool of molten adhesive. With each rotation the roller is recoated. The transfer
surface, of the roller, is knurled to hold a greater volume of adhesive. The thickness of the
adhesive is controlled by means of an adjustable blade doctor. The adhesive temperature and
the viscosity of the adhesive formulation also affect the thickness of the film.
