Georg Sahm GmbH & Co. KG, based in the German town of Eschwege, is a technology leader in the automatic winding of all kinds of technical yarns. Its portfolio includes automatic and manual precision winding machines, automatic bobbin removal devices and transport systems. For extremely precise winding of the high-performance fibres and technical yarns, SAHM uses the TWINSTAR II automatic precision cross winder. The stringent quality requirements of its customers demand high-quality technologies such as Controlled Pneumatics and standard pneumatics from Festo.
High-performance fibres, multifilaments, coated and twisted yarns: Cost-efficientfinishing processes require equal running lengths and higher coil weights when coiling yarns, which operators can no longer handle. Parameters such as tensile force, winding speed or winding precision decide whether a technical yarn can be turned into a flawless high-tech product. A solution was needed that would combine high control quality during winding with a flexible and very reliable solution for changing the coils. The high-performance yarns are then used to make high-quality products for safety-related areas, such as fire and safety clothing, helmets or automotive applications.
