Depending on your industry, you may refer to this machine as a dual head hot melt roller coater, a double-head or twin-head hot melt roll coater, 2-sided wall panel laminator, 2-way panel laminator, or double-sided hot melt coater.

Union Tool has designed and built the only working 110" wide dual head hot melt roller coater in the world. This dual head machine has the capability of changing from a single-sided coater to a double-sided coater with the flip of a switch.

When double side coating, both coating heads are parallel with each other to apply adhesive to both sides of the substrate. The single coating operation moves the top coating head away from the bottom and automatically locates a single Teflon coated roll in the same position. Hydraulic cylinders provide the movement for these rolls.

The machine was designed to laminate walls, floors and ceilings for the recreational vehicle (RV), garage door, mobile home, and fifth-wheel towables industries.

Some of the industries we serve:

Recreational Vehicle (RV) Manufacturing — Union Tool is right in the heart of RV and motorhome country, and we've been making machinery for laying up floor, wall and ceiling panels since the industry first took off back in the War years. Travel trailers, mobile homes, fifth wheels, and towables of all kinds are made better, faster, and more profitably with Union Tool machines. These machines are adaptable to other industries as well; basically, anywhere large sheets and panels need to be laminated, coated, painted and glued up.

Entry, Security and Garage Door Manufacturers — Like wall panels in the RV industry, doors are typically sandwich constructions — a frame or core covered with various types of facing panels front and back. Union Tool makes many roller coaters and laminators preferred by door makers, including our new 110-inch "twins" ... a matching hot melt roller coater / laminator pair, big enough to face both sides of a garage door substrate in a single pass.

EPS Foam — EPS foam sheets and panels are used in many manufacturing processes. Union Tool makes several machines specific to EPS foam, and many UT laminators, coaters, feeders and stackers can be adapted to handle EPS foam.

Plastics Packaging & Forming — From application of blister / skin pack material to silicone coating of plastic web materials prior to forming, Union Tool knows how to handle plastic sheets, films and panels.

Metal Stamping, Drawing and Forming — From lubricant coating and painting to wire brush finishing, many Union Tool machines find homes in metalworking plants of all kinds. Stackers and feeders keep those sheets of aluminum, brass, steel, and other ferrous and non-ferrous metals moving down the processing line ...

Architectural Glass — Union Tool makes roller coaters specifically designed for glass substrates. The making of spandrel glass especially requires the particularly smooth paint coating that our Reverse Roller Coaters provide ...

Printed Circuit Board (PCB) Manufacturing — One of the primary requirements in the manufacture and assembly of printed circuit boards is protecting the surfaces of the boards, which means gentle handling by the edges. While most of the machines in this category are specific to the PCB industry, they can be adapted to handle delicate materials of all kinds where surface protection and precision handling are required.
