ABSTRACT:
Mounted in tandem on an elongated frame, a plurality of applicator head assemblies affords a versatile machine for bonding a decorative coating even to a relatively complicated pre-shaped edge of a workpiece. Means on the head for accurately positioning a rotatable applicator wheel having a circumference of silicone rubber profiled to match the edge permits the wheel to urge the coating with precision and uniformity onto the contoured edge of the substrate. An external radiant heat source raises the temperature of the silicone rubber periphery which, in turn, transfers heat by conduction to a transfer foil, thereby releasing the foil carrier and bonding the decorative film to the substrate edge. Pressure applied by the wheel in the plane of the wheel creates a wheel flat resulting in increased contact area and dwell time, thereby enhancing bonding precision and strength.
