Voith Gecko OneStep is a unique system for start and end gluing on the winder. 16 gluing machines, with a Voith VariFlex winder using two-drum technology, have been sold in the past three years and also been successfully used in several rebuilds. Along with start and end gluing, Gecko OneStep also provides for perforation of the paper web.
The lizard family of geckos was the inspiration in naming the Voith Gecko OneStep, and for a good reason. Lizards’ feet have tremendous adhesive power and even allow the animals to hang upside down on glass panes. The performance features of Gecko OneStep are also unique; they ensure that the paper web adheres to the core.
Exact and quick functioning. When a new set is to be wound in the winder, both end gluing of the cut finished reels as well as the initial gluing of the paper web have to take place on the new core. With Gecko OneStep, preparation of start and end gluing is done at full machine speed, which minimizes time and production losses. The gluing machine is attractive due to its reliable handling and its exact and quick functioning. If a reel change is imminent, hot glue is applied with a low-maintenance nozzle on an anti-adhesive-coated transfer roll. The perforation knives for cross-cutting the paper web are on this transfer roll between the glue traces. The roll turns during a reel change. A glue trace is applied as end gluing on the paper web of the finished reel. Then perforation takes place, which later allows separation of the paper web. With the exactly positioned glue traces, the paper web then adheres to the core. The rugged and universal set-up means Gecko OneStep has a broad range of application, from thin paper of less than 30 g/m² all the way to board and packaging paper of over 440 g/m².
New generation of glues is double strength. Together with an optimized coating of the applicator roll, a newly developed generation of glues now provides for even better durability of the end sheet gluing. The strength of the gluing has been doubled, which improves both the storability as well as the transportability of the paper rolls. The optimized coating on the transfer rolls also has another positive effect: its service life has been tripled.
With Gecko OneStep, paper manufacturers can rely on a proven system that was developed with a high degree of technological know-how. Durable and resilient adhesion is ensured using only small amounts of glue which is also suitable for indirect contact with food. Together with VariFlex winders, Gecko OneStep offers a reliable system for the highest productivity.//
