HML-12 Profile Laminator
The HML-12 Profile Laminator applies hot melt adhesives to the back of the various paper, foil, or vinyl webbings, and wraps the webbing around all types of profiled wood, extruded plastics, and metal substrates. The base hot melt wrapper is furnished with two unwind spools and film tensioners, a splicer assembly, a hot melt adhesive applicator, a film tracking system, an edge guide assembly, a substrate cleaner, a top infeed press roller assembly, a touch screen control panel, and a continuously driven six-segment removable cartridge section.
The HML-12 Profile Laminator film rolls are pneumatically locked on the unwind shafts which contain a fine adjustment to aid film tracking. Each film unwind roll is provided with tension control to improve adhesive application and to prevent wrinkling of the film. The hot melt wrapper has a splicer assembly that automatically joins the starting edge of a second feed roll film to the end of the first fed roll film to provide a continuous web and an uninterrupted operation of the wrapping system. Includes an adjustable width “no-drip” slot-coater adhesive applicator.
The hot melt wrapper has a substrate cleaner to ensure that the substrate is clean before the film is applied, which maximizes adhesion with the wrapped substrate to give a fine finish. An infrared preheating oven is positioned in the system to preheat the substrate surface before the laminate is applied to it.
The HML-12 Profile Laminator wrapping section consists of twenty-one continuously driven roller sections that drive the material through the wrapping section. Each drive section is removable to facilitate the substitution of pressure rollers in the position for wrapping the laminate around the lower surface of the substrate. There are six pressure roller assemblies, three on either side. Each assembly consists of five pressure rollers that can be independently positioned. Each assembly can be easily removed for fast change over from one profile to another on the hot melt wrapper. One-half of the drive rollers as well as half of the pressure roller assemblies can be quickly adjusted in and out using a hand crank and digital readout to quickly adjust to different widths of similar profiles. Each pressure roller can be quickly disconnected using a spring detent assembly.
