(Australia) Technical Benefits Here are just some of the ways our equipment can improve your capabilities and efficiency. Heat, Speed, Pressure... Hot air and hot wedge rotary heat-sealing are welding processes used to join thermoplastic materials in order to create many products like truck tarpaulins, inflatable boats, industrial filters and environmental liners. The three principle components for rotary welding are heat, speed and pressure. The precise combination of these factors allows for the achievement of a properly-welded seam.

They never let us down.” George Aragon President, Maravia Hot Air Welding Hot air rotary heat-sealing is a welding process used to join thermoplastic industrial fabrics and films using very precise heat, speed and pressure settings. The correct combination of these three parameters allows for the achievement of a complete weld. In the case of hot air, heat is provided by blowing compressed air across electrical heat elements and is injected at the welding point. The tightly controlled temperature can range from 100°F to 1,350°F (40°C to 750°C). Some of the scenarios and applications for which hot air is the best choice: • The product being welded has many different shapes and curves. • There is the need to change the weld width often throughout the manufacturing of a product or product line. • There is a need to use multiple welding heads simultaneously. • There is a need to produce a versatile product range. • There is a need to start and stop often throughout the welding process. 4 “Our machine seams 20,000 sq ft of billboards with pockets on 7 ft media every day in 2 shifts probably the most utilized machine of yours in the world today!!” G.R. Srinivasan Digital Print & Impressions Bangalore, India Jeremy Carpenter & Brent Nussbaum Team Leaders 17 M-100 Multi-Seal Systems The Miller M-100 Multi-Seal System is by far the most efficient system available for joining straight seamed, multi-width panels. This system is custom built to your specifications and dimensions. The M-100 will pull fabric directly off roll and produce multiple continuous seams to any desired length and width. The number of seams is determined by the number of laterally adjustable welding heads. The welding heads can be easily positioned for different product specifications and panel widths. The M-100 Multi-Seal System can be used as a complete fabrication center. We offer unwind stand assemblies, powered rewinding equipment, fabric accumulators, programmable footage counters, and automatic cut-to-length systems. An example of the M-100 fabrication center’s versatility: Your fabric is dispensed from the unwind stands, three panels are welded together with two overlap seams, webbing is welded to each panel, the two edges are hemmed, the hems are automatically grommeted, the fabric is measured and cut to length, and then rewound —all in one operation with minimal labor. “We can essentially build any in-line welding system to meet your production needs.” Remove and replace with multi-seal photo (more current) 16 “The M-100 Series reduces labor and increases production.” “The people at Miller Weldmaster are true professionals who really know their product and always treat us in a friendly, courteous manner.” Dan Kemmer Canadian Tarpaulin Saskatoon, Saskatchewan Hot Wedge Welding Like hot air, hot wedge rotary heat-sealing is a welding process used to join thermoplastic industrial fabrics and films using very precise heat, speed and pressure settings. However, in the case of hot wedge welding, a heated wedge is precisely positioned at the weld point, providing the required heat. The fabric or film is then pulled across the heated wedge. The tightly controlled temperature of the wedge can range from 100°F to 920°F (40°C to 490°C), thus producing a perfect weld. Some scenarios and applications for which hot wedge is the best choice: • The product to be constructed is made of film. • There is a need for a quiet work environment. • The product being constructed is made of a very thin fabric. 5 endorsed by: Sunbrella is a registered trademark of Glen Raven, Inc. ® “Miller Weldmaster’s acrylic welding systems have allowed us to construct quality awnings and boat tops to meet our customers ‘No Leak’ requests.” Phil Russell PCR Restorations Acrylic Welding Hot air rotary heat-sealing is a welding process that can also be used to seam acrylic fabrics for the fabrication of awnings, boat covers, etc. Miller Weldmaster offers a special laminated tape that has a very strong adhesive on both sides. This combination, heat-activated adhesive followed by pressure from the weld rollers, produces a very strong bond. With the Miller Acrylic Welding System, needle and thread are not used. This allows for the creation of a “No Leak” water-tight seam without the worry of thread-matching or thread-fading. Independent test lab results indicate that the acrylic welded seams are 25% stronger than the sewn seams. 6 Some of the features of the Miller 112: • Faster welding speeds than any other sealing technology to increase your production time. • Superior seam strength for a quality product. • Easy to operate and maintain for maximum up time. • Will not affect other surrounding electronic equipment so placement of a Miller Weldmaster is not critical.
