Sacks made on the AD CONVERTEX bottomer ensure perfect protection for a broad range of products even under the most adverse transport and handling conditions and in the most severe climatic situations.

Backed by the unique experience and competence of
Windmöller & Hölscher in the design and manufacture of
bottomers, the AD CONVERTEX offers outstanding economic advantages. Marketing of the machine world-wide is handled
by our sales partner BSW / Bag Solutions Worldwide, the
specialist for complete systems as well as individual components for the production of woven PP sacks.

The essential advantages of the machine at a glance:
