Envelope machine W+D BB550 XL

W+D BB550 XL

Large Envelope inserter

The expanded format spectrum and the processing of packaging thicknesses up to 1” are the main features of the W+D BB550 XL larger envelope inserting system. The servo-driven machine does not only process all formats from C6/DL and B4, but also large “flats” booklets, and open-end envelopes with a larger insertion depth up to C4 shipping pockets with the flap on the short side.

The W+D BB550 XL is thus a highly efficient and flexible inserting system that meets all requirements. In addition, the W+D BB550 XL easily handles cardboard and express envelopes (FedEx, UPS, etc.) and can be equipped with hot glue to close the flaps.
