Definitions
- the present invention relates to a device for sheathing a filiform material, consisting of a set of threads and / or filaments, with an organic material in the fon ⁇ du state.
- wiring heads There are already a number of devices, called wiring heads, covering heads or angle brackets, mounted at the end of an extruder, which enable a layer of thermo-plastic organic material to be deposited. the surface of a threadlike material.
- a device of this type is described, for example, in patent US-A-4,713,139.
- This device essentially comprises a conduit for guiding the material and, at its exit, an annular orifice through which the material organic is delivered, arranged concentrically to the outlet of said material.
- the organic matter is stretched in the form of a cone by the moving material and is applied to its surface a few millimeters after it leaves.
- the principle of this device limits the speed scrolling of the material which, according to the example cited, does not exceed 1 to 2 meters per second. Beyond this speed, the material may no longer be sheathed regularly because the organic matter is then stretched too violently not to break.
- Patent application EP-A-393 536 describes another type of device, which allows the filiform material to be brought into contact with the organic material inside said device.
- the latter essentially comprises a device for guiding the material at the inlet and at the outlet and, between the two, an impregnation chamber connected directly to the extruder.
- the material in this case consisting of a wire formed from a multiplicity of filaments, is brought into contact with the material under pressure which can thus permeate it to the core.
- the injection of the organic material into the central chamber is made perpendicular to the path of the wire, which causes it to be split and the separation of a certain number of filaments relative to their neighbors.
- the pressure preferentially exerted on one side of the wire also has the effect of causing an irregular distribution of the filaments within the organic material. This effect is, moreover, sought after.
- this device therefore does not make it possible to obtain a composite material in which the filiform material has retained its cohesion.
- the introduction of the filiform material into the known devices takes place through an orifice situated on their longitudinal axis.
- This method of introduction is not without presenting some difficulties when the material consists of very fine filaments and when, following a rupture of said material, it is important to resume the sheathing operation very quickly.
- the present invention relates to a device which makes it possible to sheath and, possibly, to impregnate a filiform material with a layer of thermoplastic organic material, at a speed greater than that attained by known devices and in which said material can be introduced quickly.
- the current. invention also relates to a device which makes it possible to obtain a composite material, consisting of a set of threads and / or filaments sheathed and, optionally, impregnated with organic material, within which the threads and / or filaments retain a regular distribution.
- the present invention relates to a device which makes it possible, in particular, to obtain a composite yarn whose core, formed of a bundle of filaments, is coated with a thermoplastic organic material.
- the objects of the invention are achieved by means of a device mounted at a square head at the end of an extruder, which comprises, along its axis, an inlet orifice which is followed by a hollow punch, the conduit opens into a central channel, said channel being connected to the extruder by means of a supply chamber, then, at the outlet of the channel, a die, at least part of this device being mobile or removable the dépla ⁇ cement 'of said portion allowing the opening and compact ⁇ ture of the device over its entire height from its periphery to its axis.
- the device according to the invention may include a longitudinal slot over the entire height of said device, which extends from its periphery to its axis.
- the movable part is a sealing piece which fills the slot and whose profile makes it possible to reconstitute the walls of the various conduits inside the device.
- the device according to the invention may consist of two parts symmetrical with respect to a plane passing through its axis.
- the fixed part is connected to the extruder; the movable part pivots around a longitudinal hinge which is integral with the two parts.
- the two parts are applied against one another and re ⁇ constitute the walls of the various conduits inside the device.
- the filiform material can be mechanically driven again before being introduced laterally in the axis of the device.
- the closure of the latter and the resumption of the injection can be carried out quickly.
- the internal structure of the sheathing device is also important insofar as it must allow regular coating of the filiform material, even if the latter runs at high speeds, knowing that the organic material cannot be injected at high pressures.
- the filiform material for example a wire formed from a multiplicity of glass filaments, guided beforehand by the conduit of the punch penetrates into the central channel along its axis, zone where it is in contact with the thermoplastic organic material. in the molten state under pressure.
- the cross section of the channel is constant over at least part of its length and greater than that of said conduit.
- the organic matter arrives through one or more orifices directed towards the axis of the channel and distributed concentrically with said axis, and exerts on the surface of the wire a regular radial pressure directed towards the center of said wire.
- the wire thus subjected to a field of balanced pressures during its path in the channel, does not tend to fragment.
- the wire is subjected to constant radial pressure over at least part of its path in the channel. This promotes the quality of the wire impregnation.
- the orifice (s) of the supply chamber preferably open out at the inlet of the central channel.
- the molten material preferably arrives in the channel through a single orifice which opens over its entire periphery, for example in the form of an annular orifice when the channel is cylindrical.
- this concentric supply makes it possible to maintain the cohesion of the filaments which constitute the wire, the adjustment of the pressure and / or of the viscosity of the material coming into contact with it, that of its speed of passage through the device, also makes it possible to impregnate it, at least partially, with organic matter.
- the device according to the invention thus makes it possible to obtain a wire, the central part of which is formed by a bundle of filaments not impregnated with organic matter, surrounded at its periphery by an impregnated zone, the assembly being coated with a layer of determined thickness.
- the supply chamber surrounds the hollow punch and presents, at its lower part, a duct of conical shape which converges towards the axis of the central channel.
- This conduit terminating in the channel through an annular orifice makes it possible to inject the material in the molten state into said channel in a direction close to that followed by the wire during movement.
- the difference which may exist between the speed of the wire and the average speed of the stream of material in the molten state can be considerably reduced.
- the speed of the material is at least equal to 0.5 times the speed of the wire. This reduces the pressure under which the material is injected into the channel. This pressure is less than 50 bars and preferably less than 30 bars. This also makes it possible to significantly reduce the projection to which the organic material is subjected as soon as it comes into contact with a wire which moves at high speed.
- the device makes it possible to sheath and, possibly, to impregnate a wire which passes through it at a speed greater than 5 meters per second, without the quality of the coating suffering.
- This advantage makes it possible, from yarn extracted from rolling, to significantly increase the length of sheathed yarn per unit of time.
- This advantage above all makes it possible to integrate the device according to the invention into the installation for manufacturing the wire which it is desired to sheath.
- the device according to the invention can, for example, be installed in an installation for producing glass yarn.
- Such an installation essentially comprises a die, generally made of a metal alloy heated by the Joule effect, which is used for melting the glass or for keeping it in the molten state.
- the glass flows from the die from a multiplicity of orifices, in the form of nets which, mechanically stretched, gives rise to a set of continuous filaments.
- These filaments are gathered into a wire directly entrained through the device according to the invention before, for example, being wound on a rotating support.
- Accidental breakage of several filaments leads to production stoppage. It is then necessary to reform all of the filaments and then to combine them into a wire which is drawn mechanically. Immediately after this operation the wire being drawn is instantly introduced into the device according to the invention. The sheathing operation can then resume with the minimum loss of time.
- the implementation of the device according to the invention in the context of a direct process eliminates the manufacture, packaging and storage of windings of wires, costly steps which precede generally the sheathing operation.
