Ring travellers are used in textile millsaround the world to process yarn. These products have a direct effect on the quality of yarn produced as their action physically turns the raw material into finished product. Eadie of Paisley, Scotland, started manufacturing ring travellers over 100 years ago and, since then, the market for these products has grown considerably. Originally made from steel, the 1950s saw the introduction of Nylon travellers, offering many advantages to customers. Traveller speeds could be increased, wear on Spinning Rings reduced, the need for lubrication was reduced and an improved more uniform yarn resulted. There are several leading brands of Ring Traveller available today. There are even small local workshops scattered around the world making small ranges of these products though these products tend to be very rudimentary.

Uses
PSM Standard is the original sintered material and can be used with Nylon or lightweight Metal travellers. PSM Standard material is ideally suited for glass fibre twisting, worsted spinning, cotton twisting, sewing thread spinning and for drawtwisting where both textile and industrial deniers are processed. PSM 40 has a more porous structure than PSM Standard which provides increased lubrication. Only Nylon travellers should be used with PSM 40. Due to the higher porosity, PSM 40 is ideal for production of coarse count yarns and heavier denier cord processes i.e. tyre cord, polypropylene, twines and carpet yarn etc. PSM 70 is more ductile and fatigue resistant than PSM Standard due to the increased density and additional alloying elements. It can be used with Nylon or light weight Metal travellers. PSM 70 rings are widely used in worsted and semi-worsted processes in which wool and synthetic fibres and blends are produced. It is recommended for draw twisting of synthetic filament. PSM 100 has the same ductility and fatigue resistance as PSM 70 but with a more porous structure. It can be used with Nylon or light weight Metal travellers. It is a versatile material and is particularly suitable for CSIRO spun yarns. PSM 21 C, the most recent development of sintered material, was designed to give a much higher permeability than PSM 40, and consequently a longer life. Only Nylon travellers should be used with PSM 21 C. The increased permeability of PSM 21C is particularly suited to heavy duty spinning and twisting processes such as wool, carpet yarns, tyre cord and technical yarns.
