LENservo
Unique system for banknote and high security numbering
Experience the latest innovation of intelligent numbering machines: The LEIBINGER LENservo. Flexible, lean banknote production by means of free programmable numbering sequences. LENservo – compact, robust, reliable. First systems are already successfully installed in banknote printing. Further fields of applications of these motor-driven systems are e. g. passports, shipping documents and lottery tickets.
Latest development of intelligent electronic numbering systems
By using the optimal dimensioning of the motors and the use of latest, highly dynamical control-electronics, a numbering machine was created, that cannot be beaten concerning performance and efficiency. Because of its compact dimensions LENservo can be used for the sheet/WEB production of banknotes in current numbering presses.
When developing the modern LENservo, LEIBINGER has again followed its philosophy and created a numbering system that is easy to handle and just as easy to maintain. Therefore the Leibinger engineers have chosen a modular construction for the numbering machine. The mechanical module with the figure wheels and the axle can easily be removed and thus offers the decisive advantage: The maintenance itself and the change of figure wheels is much easier than in conventional numbering machines.
Advantages of the construction
Revolutionary snap lid-mechanism
Due to the revolutionary snap lid-mechanism, the numbering machine can be opened deftly and the entire set of wheels can be removed and cleaned while the electronical parts remain in the case. By using this unique construction, the maintenance and set-up times can be reduced drastically. In addition to this, the compact construction of the LENservo minimizes clearance distances across and around the shaft.
Electronic controller
For the electronic control system of the LENservo we maintained the well-proven “LEIBINGER Standard” meaning that as much “intelligence” as possible has to be in the numbering machine itself. This is achieved by the latest hard- and software developments from the experienced Leibinger electronic R&D. It enables an easy communication with the external controler using a slip ring unit with only a few contact-tracks and thus provides a smooth operation.
