Barmag Expands Portfolio With IWKA Winders

Barmag, a subsidiary of Germany-based Saurer GmbH & Co. KG, has purchased the patents and
rights to IWKA elastomer winder technology from Germany-based Zentes Unitex Textile Machinery GmbH
& Co. KG.

IWKA winders, designed for the production of elastane fibers, can wind up to 16 filaments per
position at speeds of up to 1,300 meters per minute, with a tighter range of between 11 and 120
decitex.

Barmag will market the winders through its Barmag Spinnzwirn subsidiary, and will continue to
produce elastomer winders for the former IWKA program. Zentes Unitex will continue to supply spare
parts for IWKA elastomer and partially oriented yarn winders.
