Guide wheel for assemblies for fitting layers of armoring wires

A method for assembling an assembly for laying a layer of carbon armor filament around a tubular core to manufacture a flexible tubular pipe intended for the transport of hydrocarbons, the method comprising the steps of:

• providing a machine comprising at least one supporting wheel having a central passage opening to allow the passage of a tubular core through the at least one supporting wheel, the at least one supporting wheel comprising a plurality of bobbins capable of storing a plurality of carbon armor filaments so that the carbon armor filaments can be drawn in rotation around the tubular core, while the tubular core is driven in movement through the at least one supporting wheel to helically wind the carbon armor filaments onto the core;
• providing a guide wheel, the guide wheel having both a central recess and an inner circular edge bordering the central recess and also a peripheral circular edge which extends coaxially at a distance from the inner circular border, the guide wheel comprising a plurality of guide assemblies capable of guiding a plurality of carbon armor filaments respectively in translation through the peripheral circular edge, the guide assemblies being mounted around the central recess to guide the carbon armor filaments when the tubular core is driven in translation through the central recess, while the guide wheel is driven in rotation in such a way that the carbon armor filaments can be simultaneously helically wound around the tubular core, wherein each of the guide assemblies comprises a peripheral return member mounted in the peripheral circular edge to guide the carbon armor filaments towards the inner circular edge along a first curved passageway and also a central return member mounted in the inner circular edge to guide the carbon armor filaments along a second curved passageway opposite to the wheel, wherein the peripheral return member and the central return member are connected to the wheel, wherein the peripheral return member and the central return member are connected together by means of a straight guide member, and wherein the peripheral return member and the central return member can be adjusted in rotation with respect to each other along the axis of the straight guide member;
• and
• coaxially mounting the guide wheel on the at least one supporting wheel.
