Lami Lines, Machinery in Demand at Vitrum
October 28, 2011

Pujol has set out to offer new options in laminated glass production, with its autoclave-less system and new interlayer product.
Laminated glass processing lines have proven popular as introductions abound at the 17th biannual Vitrum, taking place this week at the Rho Fiera Milano in Milan, Italy.

Standing out among the introductions is a new product from Pujol in Spain.

"We think it's the end of the autoclave," said Jorge Pujol Mari, general manager. "Yes, strong words," he acknowledged with a smile.

The Pujol-100 is being marketed as the only system available that allows fabricators to laminate PVB directly without using a climate box or dehumidifier.

The new machine operates using only 70 kW, and is able to work any kind of standard PVB, and fast cycles of EVA, Mari said.

Time will tell if Mari's forecast will be correct; the company has installed one line in Columbia, while one in Madrid will be in operation within two weeks.

"We're hoping for a big response," Mari said.

Durst has designed a new way of printing on glass, providing vibrantly colored images in high resolution and little time.
Also new in the company's booth, an interlayer that Pujol expects to compare to DuPont’s SentryGlas. Information from the company states that the AB-AR film can be used in a number of applications for glass that is bullet-, impact- and hurricane-resistant.

The products will be available in the United States through De Gorter Inc. in Monroe, N.C.

Other companies are focusing on new processing for laminated glass as well.

"The great novelty in our booth this year is a laminated line that can do curved cutting of shapes," said Carlo Strappa with Intermac in Italy, The patent-pending line allows for automatic cutting of shapes and diagonal lines.

Now that the option to cut laminated shapes has hit the market, it's gaining popularity.

Among the novelties in the Austria-based Lisec booth is its new laminated glass shape-cutting line. Manfred Lesiak, marketing event manager, explained that operators might still have to break it by hand as is normal, but the option to cut shapes already laminated hasn't before been available. The line is able to process up to 10 millimeter glass and a 4.5 mm interlayer.

Peter Nischwitz, corporate communication manager for Bystronic in Germany, acknowledged the demand for laminated glass as well. The company launched its eco'lami pre-nip machinery at glasstec last October. "Now following the product development we launched the full line," Nischwitz said. It offers a complete solution from washing and positioning to unloading. Like many of the products at the show, the full line is being marketed as an option for economical entry into laminated glass manufacturing.

While not laminated glass per se, Durst Phototechnik AG in Italy offers a new printing technology that Heinz Wiedmayer notes should be used on glass that is laminated, or included in an IG unit. The engineered decorative glass production line is rapid, produces striking colors with high resolution and true reds. The glass can be handled immediately once through the line and no primer is required prior to printing. However, the Sol-Gel UV ink is subject to fading in some exterior applications if not protected by another lite. The vibrant samples at the show display the striking colors.

The company has a background in photo technology, and three years ago partnered with Saint Gobain in France to find a printing solution that was speedier than silk screening and sharper than most digital printing available. The solution was the development of the Rho organic Sol-Gel ink, an organically pigmented, volatile organic compound-free ink system designed for durable, highly adhesive printing on glass. Though launched at glasstec last year, the product has only just recently come to market as the company has obtained ASTM and EN certifications for its ink.

Vitrum continues through Saturday. Look for the December issue of USGlass Magazine for the full Vitrum review.
