Our on-edge conveyor

The very frequent emptying of a conveyor belt often requires an additional operator when producing with a high-speed envelope inserting system. Also, to keep up with the system, the processing speed is often reduced.With our on-edge conveyor W+D OC4, we offer you the solution to increase productivity and to improve efficiency in the workflow. The system processes envelopes in formats from C6 to C4 and variable thickness of up to 10 mm. The system can be used as stand-alone unit or in combination with the W+D PT4.
