The Buhrs 4700 poly and paper wrapping system is specially designed for distribution of non-addressed sets of retail brochures and promotional mail.  The system boasts a perfect combination of a low gathering section with mobile feeders, a servo-driven wrapping module and the new Buhrs System Controller.

Buhrs 4700 – Principle of the system

On the Buhrs 4700 it is no longer necessary to stop the system in between two different jobs, thereby increasing productivity enormously!  Ideal when processing promotional mail composed selectively for many different zones.

Changeover from one production run to another can be performed whilst running. Three main features make this possible. The feeders are synchronised automatically with the gathering chain of the system by the AFS (Automated Feeder Synchronisation) and will be engaged automatically based on information from the BSC (Buhrs System Controller) database.

By measuring the length and thickness of the product just before the wrapping section, the AWS function enables the wrapping unit to set itself and adjust the seal position automatically.  When gathering and wrapping sets of non- addressed retail brochures and promotional mail for zoned distribution, this can improve net output enormously!  This is all possible in combination with BuhrsWrap®, which guarantees tightly wrapped products without any overlap.
