In 2004 Gruschwitz moved from Neu-Ulm to Leutkirch im Allgäu after the company had previously taken over two other companies in the textile industry (Fritz Zorn GmbH & Co. KG, Leutkirch and Lozetex GmbH Tech-Twists, Winterlingen). In 2005, the operative business was completely outsourced to "Gruschwitz GmbH Tech-Twists", also located in Leutkirch im Allgäu. This 100% subsidiary is a leader in the development and production of technical threads, yarns and sewing threads in Western Europe. Both simple natural fibers and modern man-made fibers are processed as raw materials. Gruschwitz is now more than 75% owned by Philipp Daniel Merckle and employs around 150 people in Leutkirch im Allgäu.
