The manufacturing of bookbinding-threads is based on a tradition of more than 30 years in Thuringia. As company Zwirnerei Zwigotex GmbH, sealing threads for the technology thread sealing were produced in Gotha.
After the integration of Zwigotex into ZIPPEL AG, ZIPPEL-ZWIGOTEX produces sealing threads for bookbindings in Crossen/Thuringia.
