Steel Vertical Rings & Travellers

Vertical Rings & Travellers

Vertical Rings

Vertical Rings can be manufactured from either Steel or PSM (Porous Sintered Metal) Material. Steel rings should be used in very harsh conditions where heavy steel travellers are required. Where conditions are not so severe, we would recommend the use of PSM Material, as this allows better lubrication of the bearing area and therefore improved performance. Please see our ‘PSM Ring’ page for further details.

PSM Rings are available in five different materials, each suitable for particular operating conditions.

 

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.

Vertical Travellers

Vertical Travellers are available in either Steel, Composition or Temlon (Nylon) material.
Standard Steel travellers can be provided in a wide range of shapes, wire sections and coatings to suit particular conditions. The Composition traveller is made with a special metal alloy which will not rust and is therefore particularly suitable when wet-spinning.

CPH (Chrome Plated Head) travellers were developed by Eadie for the synthetic fibres industry. In this traveller the head area is coated with an extremely hard and smooth layer of Chrome. This provides a very high resistance to yarn cut and thus prevents damage to the yarn. It is particularly effective when working with very abrasive yarns such as Polyester filament.

We also have an extensive range of vertical Temlon travellers for rings of depth from 6.3 mm up to 38.1 mm. These Nylon travellers can be supplied in standard and glass filled form. In cases where very abrasive yarns are being produced we would recommend our Metal Insert (MC) traveller which has a specially toughened and treated metal insert in the yarn passage area.
