Union Tool - Adhesive & Equipment, Inc. utilizes quality rollers and coaters from partner Union Tool Corporation.

ROLL CONFIGURATIONS
The roll configurations shown are representative of the most common methods of roller coating used in industry today. Double coaters, such as Models A and B, apply coating from the top and bottom rolls to both sides of the material (but can be used as single top or bottom coaters). Single coaters, such as Models C and D, apply coating from the top or bottom of the rolls onto only one side of the material.

The liquid coating in Model A is held in the crotch or trough formed by the coating and doctor rolls. As the rolls rotate, the material is metered through and a controlled amount of coating is applied to both sides.

Coating material for the top coating roll in Model B is held in the trough or crotch formed by the coating and doctor rolls. The bottom roll receives the coating material from the pan in which it runs. The coating material for Model C is held in the top crotch or trough with the pan underneath.

In Model D, the coating material is held in the pan in which the roll runs.

A wide variety of roll coverings are available, including Neoprene, gelatin, Thiokol, Urethane and plated steel. The rolls are usually smooth ground but can be corrugated depending on the type of material used for coating and the amount to be applied.

HOT ROLL LAMINATORS
This particular machine was designed to laminate a protective plastic onto one or both sides of EPS foam core. Both foam and film pass through a set of heated teflon-coated rolls at a precision-controlled temperature and speed for greater accuracy and effeciency. Quick change chucks and air brakes ensure proper tension on the film while it is being laminated.

ADHESIVE ROLLER COATER
This machine was specifically designed to apply water and solvent based or phenollic resin adhesive to the top/or bottom surface of clutch and brake facing plates in a single pass.

SPECIAL APPLICATION COATERS
Union Tool's expertise in roller coating technology enables us to design and build coaters to meet virtually any special need. Many times an existing machine can be adapted for a special application with a minimum of additional tooling.
