"We pull all the strings," jokes André Gall. The founder of WireStyle creates works of art with his team from thousands of nails and a kilometre-long thread using machines developed in-house. A photo or graphic serves as a template. The rest is done by his software and the machines - at breathtaking speed. Gall relies on precision tools from Tübingen-based Paul Horn GmbH to cut millions of nails before insertion. With the help of the S274 system, the nailing machine hammers up to 12 nails per second into a plastic sheet.
