Abstract:
A sheathed thread comprises a bare thread coated in a rubber sheath. The sheath comprises a plurality of segments spaced apart from one another along the bare thread in such a manner that bare portions of thread alternate with sheathed portions of thread. The device for fabricating the sheathed thread comprises a sheathing chamber through which the thread passes. An isolator member is movable between a position in which it isolates the portion of the thread passing through the sheathing chamber from the rubber, and a position in which it puts the portion of the thread passing through the sheathing thread into contact with the rubber.
