About BW Converting GmbH
Who we are
Founded in 1913 by Alfred Winkler and Max Dünnebier, Winkler+Dünnebier Maschinenfabrik und Eisengießerei GmbH & Co.KG invented the rotation principle for contour grinding machines. In 1976, W+D established the "Hygiene" business unit and began producing hygiene and fabric products. In 2016, W+D became part of the Barry-Wehmiller family and acquired the brands F.L. Smithe and Halm Industries the following year. BICMA Hygiene Technologie GmbH was acquired in 2018, strengthening the focus on the hygiene sector. In 2023, W+D was merged with five other Barry-Wehmiller companies to form BW Converted, uniting the legacy of quality and innovation of each product brand under a global organization.
