BIRD FRIENDLY GLASS PRINTING ON ROLLMAC ROLLERCOATERS
Environmental protection and a policy of environmental friendliness are a priority for us. Therefore, we are very pleased to announce that Rollmac, a major manufacturer of rollercoaters, has come up with an improvement to enable the printing of "bird friendly" glass.
Glass facades of buildings and other glass structures are a big threat to birds, due to their transparency and reflectivity. Each year collisions cause the death of millions of birds. When vegetation or clear sky is reflected in the glass, birds are not able to distinguish between a real tree and its image. The architectural community and glass industry are actively addressing this issue with the best possible solutions.
Proudly in the loop, Rollmac presents a new technology targeted to the protection and defence of volatiles.

The “bird friendly” concept involves dedicated technological features in the rollercoating machine and ceramic paint that enable to deliver a glass with anti-birdstrike characteristics.
A “bird friendly” glass is basically a transparent glass printed with a small geometrical pattern. The paint can be a solid or acid-etch ceramic frit. Printed amount is small, in average approx. 60 μm., and the acid edge ink delivers a semi-transparent effect.
What is important in this job is the perfect repeatability of the design, or more specifically the pattern must be printed in the same place for every glass sheet. The distance of the pattern from entry edge of sheet must be the same.
The related technology is composed by:
1- mechanical lining-up devices to allow the manual positioning of the sheet
2 - an electronic system with sensor that reads the entry edge of the glass sheets and synchronize the starting of the pattern printing.
3 - encoder fit on the engraved roller gearmotor and a sensor that reads the position of the engraved printing roller.
4 - dedicated software for the programming and control
The printing is carried out in synchro mode by using an engraved rubber sleeve. Available patterns can be found on Rollmac website: Design engraved rollers for float glass - Rollmac - coating and finishing machines
The bird-friendly feature is available on new machines and, as upgrade kit, for machines already in operation not older than 2015.
