Abstract: This invention relates to a downstream closure device for apparatus used in treating large-diameter insulated electrical conductors, the device comprising a main exit gasket, a movable plug, an auxiliary exit gasket borne by the plug, and means for controlling the movement of the plug.

Abstract: A machine for manufacturing cables by stranding individual wires, comprising: a pay-out apparatus having four pay-out reels and fixed supports therefor; a stranding apparatus situated after the pay-out apparatus and comprising a forming die receiving the individual wires; a take-up apparatus having a take-up reel, a support for the take-up reel, and a cable-puller for pulling the cable through the die at a predetermined speed; and further comprising wire-tensioning devices disposed between each of the pay-out reel supports and the die, each of the wire-tensioning devices comprising a guide member for one of the wires, disposed at a fixed location and coaxial with a respective one of the reels, a zone situated before the guide member for non-guided passage of a portion of the wire from the reel to the guide member, a motor for driving each of the pay-out reels at a variable speed of rotation, the speed being sufficient to cause the portion of wire to assume the form of a loop under the effect of centrifugal fo

Abstract: A winding machine equipped with a traverse mechanism to protect, for example, a reel or wire wound on a reel should feed wire break during feeding of the reel. The mechanism includes a carriage, borne by a support, which moves back and forth along the entire length of a reel and carries a pulley for guiding wire that is wound on the reel. A circular protective channel coaxial with the reel and borne by the carriage moves back and forth with the carriage. The channel includes a circular track portion extending in a plane parallel to and laterally offset with respect to the plane of the pulley, and a deflection portion situated in the same plane as the pulley and limited by a deflection wall.

Abstract: A cable-winding machine resting upon a foundation and having two uprights supporting two drum-supports respectively, a crosspiece connecting the uprights at their ends and a traverse mechanism movable along the crosspiece. Cooperative movement of the uprights and the traverse mechanism keeps the deflection of the cable to be wound at a desired level.

Abstract: A winding machine for metal wire including apparatus to protect, for example, a reel or wire wound on a reel should feed wire break during feeding of the reel. The apparatus includes: a support for at least one reel; a motor for driving the reel in rotation; a guiding mechanism including a traversing carriage bearing a pulley for guiding the wire as the wire is wound on the reel; and a protective device, to protect the reel in the event of wire breakage, including two protective plates of arcuate shape extending the entire length of the reel. At least one of the plates is hinged about an axis parallel to that of the reel and is movable between an open position and a closed position in which one of its edges meets a corresponding edge of the other of the plates, the opposite edges of the two plates being spaced from one another so as to define a longitudinal slot between them.

Abstract: A machine for alternate twisting of metal wire or cable, comprising a frame and a storage unit provided with two end-positioned twisting members and alternately driven about the axis of the wire or cable in first one direction and then the other, wherein the storage unit is linear and comprises a straight cable-supporting tube through which the wire or cable passes and which is caused to rotate at a speed equal to or greater than that of the twisting members and always in the same direction as the storage unit.

Abstract: This invention relates to an apparatus for winding a cable or a flexible tube on winding supports mounted on winding-machines, the apparatus comprising at least two winding supports, a guiding and shearing mechanism having at least one exit opening, and driving means, the guiding and shearing mechanism being disposed facing the winding supports, and the driving means being adapted to advance the cable or tube towards the guiding and shearing mechanism.
