The Means

A Specialized Team

Bows are developed in a real technical partnership thanks to the collaboration with the major cable makers.

The team is composed of a dedicated staff to comparative studies, trials, customisation and upgrade of obsolete designs :

• R&D Engineers specialised in materials
• Design Officers working on Autocad 3D pro-engineer
• Trials Engineers testing new models onto the Bow Testing Machine (see below)

High Technology Components

Main components are in stock to compose prototypes in short times :

• “High module” components (aeronautics qualification) : pre-shaped carbon fibres, aramide reinforced materials, …
• Low friction coatings selected according to the product to run : chrome-plated wear strip, polished wear strip , “Topslide”, plastic material, …
• Wide range of wire path accessories in stock : eyelets (ceramic, carbide, ...), wedges, tubes, …

An Exclusive Equipment for Trials

The Bow Testing Machine (“MTL”) enables to consistently get the best out of bows, according to the different products and machine types.

The equipment simulates twinning / stranding machines to check vibrations levels, deformation, electrical power consumption, sound levels and friction of the product inside the bow.

• Reels : 560 to 1250 mm
• Speed : up to 4000 RPM (up to 8000 TPM)

According to the results obtained on the Bow Testing Machine, new models are regularly upgraded and adapted to customer needs : better durability of the parts, vibration and mass reduction.

Indeed, if the bow is not appropriated, the power consumption can be increased, as well as the tension (up to 25%). The mass is also capital for the main bearing housing lifetime on a strander.
