Definitions
- the present invention relates to an improvement made to the devices used for drawing a wick of fibers during a spinning operation making it possible to transform it into a yarn. It relates more particularly to an improved device, which associated with a drawing device proper, makes it possible to condense, transport and optionally give additional drawing to the wick of substantially parallelized fibers leaving said drawing device.
- the device according to the invention makes it possible to solve these problems.
- the invention therefore relates to a device for drawing a wick of fibers during a spinning operation making it possible to transform it into a yarn, device of the type according to which a condenser element is arranged in succession.
- said condensing element is in the form of a movable guide surface on which the fibers are delivered tangentially, said guide surface allowing both to exert a tensile force on the end of the fibers delivered by the stretching system and limit the torsional rise communicated by the spinning system.
- the movable guide surface is subjected to the action of a stream of fluid, air for example, the flow of which is such that it promotes, in cooperation with said surface guide, transport and condensation of fibers.
- a stream of fluid air for example, the flow of which is such that it promotes, in cooperation with said surface guide, transport and condensation of fibers.
- This flow of fluid can be obtained, for example, by subjecting the guide surface to a vacuum.
- the action of fluid flow on the guide surface is preferably suppressed in the zone which follows the point where the condensation function has been carried out, that is to say in other words, substantially from from the point where the twist imparted by the spinning system is stopped by said guide surface.
- the condenser element according to the invention is in the form of a rotary guide, said guide comprising at its periphery an open groove, substantially V-shaped, the bottom of this groove being pierced with orifices connected to a suction source, suction which is suppressed in the area following the point where the stretched wick is condensed and starts to be twisted.
- the orifices can be arranged in different configurations, for example aligned, or even. be in the form of a sinusoid.
- the faces of the groove can be more or less spaced from one another and form between them an angle which can range from 30 to 160 ° but which, preferably, is generally between 60 and 160 °.
- the distance between the outlet of the drawing system itself and the point of contact of the fibers with the surface of the condenser device according to the invention will be adjusted so as to be as small as possible when only desired condense the wick, whereas, on the other hand, if you wish to communicate an additional stretch to said wick by moving the condenser faster than the feed speed thereof, it will be necessary to adapt this distance as a function of the length treated fibers.
- the condenser guide according to the invention is in the form of a rotary guide, it is advantageously positioned at the outlet of the drawing system so that the path of the wick in the bottom of the groove of this guide preferably forms an angle between 30 and 90 °.
- the suppression of the action of the flow of fluid on the guide surface, when such a flow is used can be obtained in different ways, for example by arranging a fixed cover, either inside or outside, making it possible to close off orifices that said guide surface has, possibly using a suction device for example, acting only on part of the movement of said surface, for example on part of the rotation of the guide when the latter is rotary.
- the device for drawing a wick of fibers (1) from a source feed not shown consists, on the one hand, by a conventional drawing train (2) comprising, for example, a pair of food cylinders (3), a sleeve system (4) and a pair of cylinders drawing (5).
- the drawing of the wick (1) is carried out between these elements by communicating to them different speeds.
- a condenser guide (6) at the output of the stretching device (2), therefore in this case in the immediate vicinity of the cylinders (5), is arranged a condenser guide (6), two embodiments of which are illustrated in the figures. 3,4 and 5.
- This condenser guide (6) is rotated at a speed which can either be equal to the speed Vl of output from the wick of the cylinders (5), or possibly be different.
- the speed V2 is equal to the speed V1
- the device according to the invention makes it possible to condense the wick (2) in the width direction.
- V2 is greater than V1
- the condenser guide then serving as an element for the temporary accumulation of fibers which will be called up in spurts by the rewinding.
- This condenseun guide (6) has a peripheral groove (7) having a V-shaped section whose branches form an angle of 60 ° between them. Holes (15) are made in the bottom of this groove (7).
- An internal suction is carried out inside the condenser disc (6). Downstream of said condenser (6) is arranged a conventional spinning system (8) with ring and slider.
- the condenser system (6) is arranged, at the outlet of the drawing cylinders (5), so that the fibers (1) are in contact with the bottom of the groove (7) at an angles of at least 30 °.
- the supply of the stretched wick of fiber (1) to the condenser disc (6) is made at an angle, the wire formed being called to the winding system (8) vertically.
- the suction is suppressed, for example by using a fixed cover system (9) arranged inside the guide.
- FIG. 3 illustrates an exemplary embodiment of such a condenser guide.
- the actual guide (6) is mounted, by means of bearings (10) on a fixed shaft (11).
- the drive of the disc (6) is obtained for example by means of a tangential belt (12).
- the wall (11) has an internal recess (13) and is connected to a suction source, not shown.
- the internal cavity (14) of the disc (6) is subjected to a vacuum, the outside air being drawn through the orifices (15) provided at the bottom of the groove (7).
- a flow of fluid is created on the surface of the guide which tends to exert a tensile force on the end of the fibers.
- an internal cover (9) is formed on the fixed shaft (11).
- FIGS 4 and 5 illustrate another embodiment of such a condenser disc (6).
- the disc (6) is mounted at the end of a shaft (16) rotated by a drive pulley (17) and supported by a bearing (18). As before, it has a V-shaped peripheral groove (7), the bottom of which is pierced with orifices (15).
- the suction is obtained by means of a conduit (19) whose outlet orifice (20) is in the form of an arc making it possible to locate the suction upstream of the from the point where the condensation function is performed.
- FIG. 6 illustrates a variant of a condenser disc (6) according to the invention.
- the peripheral groove (7) is also V- shaped but whose branches are much more apart than previously and form between them, in this case, an angle of about 160 °.
- the orifices (15) provided in the bottom of this groove (7) are arranged in the form of a sinusoid.
- the implementation of these devices is as follows.
- the wick of fibers (1) is drawn in a conventional manner inside the drawing system (2) and at the exit of the last pair of cylinders (5) of this system, the parallelized fibers are delivered inside of the groove (7) of the condenser guide (6) where they are pressed against the bottom of the V-shaped groove due to the internal depression and the rotation of this guide.
- the torsion communicated by the winding spindle (8) rises freely to be blocked progressively from point A2, this torsion however being blocked on the surface of the guide and not reaching the outlet of the delivery cylinders (5).
- the invention has been described using as a spinning system, a conventional ring and slider system.
- any other device could be envisaged allowing to make fiber yarns.
- the device according to the invention could be arranged upstream of a system making it possible to communicate an interlacing, a false twist or an alternating twist to a wire. It could also be envisaged to process a plurality of threads in parallel and to combine them on a single winding system by assembling them, for example, by twisting, self-twisting or any other equivalent system.
- the invention is not limited to obtaining single yarns, but it could be envisaged to associate such a device with any other conventional device for the manufacture of yarns, for example to provide, upstream of the last pair of stretching cylinders (5 supplying an additional wire intended to constitute a core.
