Weaving preparation – Mastering glass yarn application

Continual industrialisation is forcing mankind to think more and more about sustainability and efficient use of resources. Industry is increasingly searching for alternative materials to replace natural resources. A good example is the use of glass-fibre fabrics in a wide range of applications. Although the properties are very attractive, the production of glass-fibre fabrics is more elaborate.

Demanding weaving preparation
Special care is required when drawing a glass yarn warp into the harness. For this process, which until a few years ago was always done by hand, Stäubli offers automatic drawing-in machines. The sensitive and brittle glass filaments place extreme demands upon drawing the yarn into the drop wires, healds and reed and upon all machine components that come into contact with the glass yarn.

Successful SAFIR S30
The SAFIR S30 automatic drawing-in machine, very successfully introduced on the market two years age, can draw glass yarn sheet layers into the weaving harness (healds, reed) with no problem. Sheet layers to be drawn usually have no lease. Specialised optimisation of all yarn-handling components, including elimination of yarn deflection, coarse surfaces, and sharp edges is necessary to ensure problem-free and stable operation. State-of-the-art image processing technology makes it possible to faultlessly separate individual glass threads, even with varying titre, from a warp sheet with varying density.

The SAFIR S30 automatic drawing-in machine has proven to be the specialist for processing filament yarns, and now the application range has been broadened. This represents a chance for our customers to expand their portfolios and successfully position themselves in new markets with a wide variety of glass applications.
