Description

False Eyelash Heat and Manufacturing Method

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to eye cosmetic articles, and more particularly, to false eyelashes fixed to the edge of the eyelids, and more particularly to false eyelash rows and a method of manufacturing the same.

It is a known practice to manufacture a row of false eyelashes by hand gluing fibers for forming artificial eyelashes to a base portion for attachment to the eyelid. However, this manual manufacturing method is complicated and expensive. In addition, the production time is quite long, which can limit productivity.

Further, given the fineness of the fibers intended to form the artificial eyelashes, the artificial eyelashes remain adhered to the base part, since the adhesion is carried out over a very small and non-planar surface, the artificial eyelashes are removed from the base part. there is a risk of falling

Also known is the patent KR 10-1045497, which relates to false eyelashes, which are produced by inserting in a zigzag form two threads to form false eyelashes, both of which are made of two pieces of similarly contracted by chain stitches. It is secured by chain stitch to the base yarn, and each base yarn is covered with an insert yarn.

In this configuration, the manufacturing method is complicated by the fact that the artificial eyelashes are inserted in a zigzag fashion and consist of two threads knitted with chain stitches.

With more variety than can be achieved by hand, there is a need to obtain an eyelash arrangement in a simple manner, which makes it impossible to obtain various curvatures by hand and by hand.

There is also a need to obtain the advantages of a manufacturing method that can reduce production time and increase production regularity. Reducing lead times and purchasing costs can also be useful.

Finally, by simple means, there is a need to increase the quality level of artificial eyelash rows repeatedly obtained by automation, while minimizing the number of parts in the production machine.

knitted artificial eyelashes

The present invention aims to answer all or some of these needs, and according to one of its aspects: A row of false eyelashes fixed to the edge, comprising:

The base portion has a first chainstitch knit warp, and the artificial eyelashes achieve this purpose by means of false eyelash rows that pass through the chain stitch without being tied thereto.

"Artificial eyelash row" is understood as a row of eyelashes formed by synthetic eyelashes that are not entirely natural, in other words artificial eyelashes.

Artificial eyelashes do not form chain stitches. The artificial eyelashes do not form a stitch with the first bevel.

The production is simple, fast and inexpensive artificial eyelash rows are obtained. In addition, the artificial eyelashes can be arranged in a variety of ways on the base portion.

In addition, the heat according to the invention has good resistance to use, especially when handling and when worn.

It is sturdy and resistant, and can be handled easily without the risk of the artificial eyelashes falling off the base part.

In one embodiment, all artificial eyelashes in a row are formed from a single weft yarn. Thus, only one weft yarn is used to form all the artificial eyelashes. In a variant, the row may have a plurality of weft yarns, for example two or more weft yarns. Thus, it is possible to obtain a row of eyelashes with a more natural appearance, in which some artificial eyelashes intersect with other eyelashes.

The base portion may have a first chainstitch knit warp and the weft yarn passes through the chain stitch without binding thereto. The weft yarn does not form a chain stitch. The weft yarn does not form a stitch with the first warp yarn. The weft yarn passes back and forth between the two base parts, in particular extending parallel and symmetrically with respect to each other. In a variant, it is possible for the two base parts to be not parallel to each other but at an angle to each other. The angle may have a non-zero value, for example between 0.5° and 70°.

According to this aspect of the invention, there are no two separate weft yarns forming all the artificial eyelashes.

The first warp may form a closed chain stitch. In a variant or additionally, the first warp forms an open chain stitch.

The base portion may have a second chain stitch knit warp, and the artificial eyelashes pass through the chain stitch without binding thereto.

The first warp and the second warp may be interwoven. The artificial eyelashes pass through the chain stitch, but are not tied at the first and/or second bevel. The weft yarn passes through the chain stitch, but is not tied at the first and/or second warp. The weft yarn does not form a stitch with the first warp.

The second warp may form a closed chain stitch. In one embodiment, the first and second warps each form a closed chain stitch. In a variant, the first warp forms an open chain stitch and the second warp forms a closed chain stitch.

In a variant or additionally, the second warp may form an open chain stitch. In one embodiment, the first and second warps each form an open chain stitch. In one variant, the first warp forms a closed chain stitch and the second warp forms an open chain stitch.

A “chain stitch” is understood as a stitch forming loops that are placed one after the other in the manner of links of a chain, the yarn forming a loop passing over the top of the previous loop to form a column of stitches.

"Open chain stitch" is understood to mean that the two ends of the loop cover the top of the previous loop with some non-zero spacing around the width of the loop.

"Closed chain stitch" is understood to mean that the two ends of the loop cover the top of the previous loop with a substantially zero spacing, the two ends being substantially adjacent or even touching.

Creation of open and closed stitches results in stitches made in opposite directions. If both sides are made simultaneously around the needle with two threads, an unravelable effect is obtained.

The artificial eyelashes can be distributed regularly over the base part, in particular, for example always arranged at the same regular intervals.

In one variant, the spacing may be irregular. It may decrease along the base portion and then increase. The spacing between two successive artificial eyelashes of a row of eyelashes is for example 0.07 to 2 mm, preferably 0.5 to 1.5 mm, or 0.9 to 1.25 mm, more preferably 0.99 to 1.11 mm, for example about 1 mm.

In one embodiment, the artificial eyelashes may be placed in a group of artificial eyelashes, with a first small gap between one and the same group of artificial eyelashes, and a second larger gap between two consecutive groups. A group of artificial eyelashes may have 2 to 12 artificial eyelashes, more preferably 3 to 10 artificial eyelashes, for example about 6 or 8 artificial eyelashes. Groups of artificial eyelashes in a row of eyelashes may have the same number of artificial eyelashes, or in a variant, this number varies from group to group along the row of eyelashes. In one embodiment, the eyelash row has a series of groups of two artificial eyelashes, or in a variant, for example an alternating group of two artificial eyelashes and a group of eight artificial eyelashes.

The first warp and the second warp may include, for example, the following non-limiting list: a first synthetic material selected from polyolefins, PE, PP, PU, PA, PET, PBT, PES, PTFE, or polyolefins, PE, PP, PU, PA , PBT, PES, PTFE, heat-activatable adhesive or heat-activatable resin, TPU silicone, CoPA, CoPES, TPU, TPE, EVA (ethylene-vinyl acetate), polyolefin, polyethylene, polypropylene, PA , PES, PVC coated yarn.

The color selected for the first synthetic material may be similar to or similar to the color of the user's skin, or in a variant the synthetic material may be transparent. The first slope and the second slope may represent one or more colors. The first and second warps may each have one or more strands as described above.

Artificial eyelashes, and especially weft yarns, include, but are not limited to, the following list: a second synthetic material selected from polyolefin, PE, PP, PU, PA, PET, PBT, PES, PTFE, or any other thermoplastic fiber, or even made from natural fibers. It also consists of a core of polyolefin, PE, PP, PU, PA, PBT, PES, PTFE and is a heat-activatable adhesive or heat-activatable resin, TPU silicone, CoPA, CoPES, TPU, TPE, EVA (ethylene-vinyl acetate), polyolefin, polyethylene, polypropylene, PA, PES, PVC.

The color selected for the second synthetic material may be similar or similar to the color of the user's eyelashes, or in contrast may be a color that contrasts sharply with the color of the user's eyelashes, such as red, black, green, blue, the list being Not restrictive.

It may be possible to have different weft yarns in terms of diameter and color. The artificial eyelashes, and in particular the weft yarns, may exhibit more than one color. They may, for example, exhibit 1 to 5 different diameters.

The first and second warp and/or artificial eyelashes, and in particular the weft threads, can be washed in a washing bath according to Oekotex and REACH standards to ensure sufficient hygienic conditions.

The base portion may have additional yarns interwoven with the first chainstitch knit warp, in particular interwoven with the first chainstitch knit warp and the second chainstitch knit warp.

This additional thread can block knots and stitches. This may also make it possible to further limit the risk of loosening of the first and/or second warp and weft yarn(s). In addition, it can provide a reinforcing effect of the base part to which it belongs, which is advantageous for good retention of false eyelash rows.

Additional yarn may be added into the base portion comprising the first and second chainstitch knit warp yarns. In one variation, additional yarn may be added into the base portion comprising the single first chainstitch knit warp.

These additional yarns may extend in a zigzag manner in the base portion.

Assembly for forming false eyelash rows

Independently or in combination with the above, another subject of the invention is an assembly for forming a row of false eyelashes fixed to the edge of the eyelid, in particular as defined above, wherein the assembly is parallel to each other with respect to the median plane an artificial eyelash formed from at least two base parts intended to be fixed at least one to the edge of the eyelid, and a weft, in particular a single weft, extending back and forth between the two base parts, arranged symmetrically and symmetrically .

In one embodiment, all artificial eyelashes in a row are formed from a single weft yarn. Thus, only one weft yarn is used to form all the artificial eyelashes. In a variant, the row may have a plurality of weft yarns, for example two or more weft yarns. Thus, it is possible to obtain a row of eyelashes with a more natural appearance, in which some artificial eyelashes intersect with other eyelashes.

The weft yarns are disposed substantially perpendicular to the base portion with a slight warp. The weft yarn is cut between the two base parts to separate the base parts to form at least one row of false eyelashes, in particular two rows of false eyelashes. The separation can take place in particular in the median plane or, in a variant, in a plane parallel to one of the base parts, close to the latter, for example at the same level as said base part.

Each base portion may have a first chainstitch knit warp, and the weft yarn passes through the chain stitch without binding thereto. The weft yarn does not form a chain stitch. The weft yarn does not form a stitch with the first warp.

Each base portion may have a second chainstitch knit warp and the weft yarn passes through the chain stitch without binding thereto.

Each base portion may have additional yarns interwoven with the first chainstitch knit warp, in particular interwoven with the first chainstitch knit warp and the second chainstitch knit warp, as described above.

In one embodiment, the assembly has two base parts disposed parallel to and symmetrically with each other with respect to the median plane.

In a variant embodiment, the assembly may have three base parts arranged parallel to each other and symmetrically with respect to the median plane. The median plane can for example pass through the central base part, the two other base parts being arranged on either side of the central base part parallel and symmetrically to each other with respect to the median plane. In this case, there are two weft yarns, and a single weft yarn is passed back and forth between the two base parts.

In another variant, the assembly may have more base parts, for example 4 or 5 base parts.

knitting machine

Independently of or in combination with the above, another subject of the invention is a machine for knitting an assembly having a compound needle for forming a false eyelash row fixed to the edge of the eyelid, in particular as defined above .

A “composite needle” is a needle formed of two parts, namely a body and a sliding element. The body may consist of a butt, a stem and a hook. The sliding element may consist of a butt and a stem. The sliding element can slide within the stem of the body to close and open the hook of the needle. Thus, the body of the needle and the sliding element can move independently and in a synchronized manner.

Composite needles can produce tighter stitches than latch needles. This tightness makes it possible to ensure that the artificial eyelashes are fixed very well to the base part.

The knitting machine may in particular not have latch needles. A latch needle is a needle consisting of a butt, a stem and a beard, and is a latch articulated to the stem. The latch exhibits oscillatory motion along the axis of the stem, opening and closing the whiskers of the needle. The latch needle needs to work with a sinker that serves to form the stitch.

In the present invention, the knitting machine may in particular have no sinkers. Accordingly, the knitting machine according to the present invention does not have a sinker for forming stitches.

manufacturing method

Independently of the above or in combination with the above, another subject of the present invention is characterized in that it has at least the step (a) of knitting an assembly for forming a false eyelash row fixed to the edge of the eyelid, in particular as defined above, A method for manufacturing false eyelash rows, the assembly comprising: at least two base parts intended for fixing at least one to the edge of the eyelid, arranged parallel and symmetrically with each other with respect to the median plane, and between the two base parts has artificial eyelashes formed from weft yarns, especially single weft yarns, extending back and forth in

In one embodiment, all artificial eyelashes in a row are formed from a single weft yarn. Thus, only one weft yarn is used to form all the artificial eyelashes. In a variant, the row may have a plurality of weft yarns, for example two or more weft yarns. Thus, it is possible to obtain a row of eyelashes with a more natural appearance, in which some artificial eyelashes intersect with other eyelashes.

The knitting may be such that each base portion has a first chainstitch knit warp yarn, and the weft yarn passes through the chain stitch without binding thereto. The weft yarn does not form a chain stitch. The weft yarn does not form a stitch with the first warp.

The knitting may be such that each base portion has a second chainstitch knit warp yarn, and the weft yarn passes through the chain stitch without binding thereto.

In one embodiment, each base portion comprises a first chainstitch knit warp forming a stitch (the artificial eyelashes pass through the chain stitch without binding thereto), and a second chainstitch knit warp yarn forming a stitch (the artificial eyelashes are chained) stitches are passed without binding thereto).

The first warp and the second warp may be interwoven.

The knitting step may be implemented by means of a composite needle. The knitting step may in particular not be implemented by means of a latch needle. The knitting step may in particular not be implemented by a sinker.

In one embodiment, the assembly has two base parts disposed parallel to and symmetrically with each other with respect to the median plane.

In a variant embodiment, the assembly may have three base parts arranged parallel to each other and symmetrically with respect to the median plane. The median plane can for example pass through the central base part, the two other base parts being arranged on either side of the central base part parallel and symmetrically to each other with respect to the median plane. In this case, there are two weft yarns, and a single weft yarn is passed back and forth between the two base parts.

In another variant, the assembly may have more base parts, for example 4 or 5 base parts.

The method may also have a step (e) of activating at least a warp or multi-strand warp strand that is thermally soluble to secure the stitches of the base portion. Activation may comprise heating, for example, in particular by means of a stove or heating roller or steam. The activation step (e) may preferably take place after the knitting step (a) and before one or more of the steps (b), (c) and/or (d) mentioned below. This activation step (e) may in a variant take place after one or more of the steps (b), (c) and/or (d) mentioned below.

Next, the assembly is cleaned.

The method further comprises the further step of curving the false eyelash row and/or the base part and/or the artificial eyelash by applying a mechanical load in the presence of an energy stimulus causing the material of the artificial eyelash to be heated, in particular by applying ultrasound or radio frequency or by heating. (b) can have

The curving step (b) may preferably take place after the knitting step (a). This curving step (b) may take place simultaneously with or before one or more of the steps (c), (d) and/or (e) mentioned above or below, or in a variant after it. In particular, steps (b) and (c) can be simultaneous or, in a variant, successive, preferably step (b) occurs before step (c) or, in a variant, step (c) is followed by step (b) ) can occur later. Step (b) may occur after step (d), or in a variant, step (d) may occur after step (b). The separation step (c) and the cutting step (d) and the curvature step (b) may take place simultaneously or sequentially.

Heating may include application of steam.

The method also comprises cutting the weft yarns, in particular in the median plane, to form in this way at least one row of false eyelashes, in particular two rows of false eyelashes, by heating, in particular by mechanical cutting, by applying ultrasonic waves or radio waves, or by cutting said 2 There may be an additional step (c) of separating the base parts. The median plane may be a plane of symmetry between the two base portions.

In one embodiment, the two base parts arranged parallel to and symmetrically with each other with respect to the median plane are separated in the median plane.

In a variant embodiment, the three base parts are separated in a separation plane parallel to one of the base parts, close to the latter, for example at the same height as said base part. This can be, for example, a central base part and a side base part.

Finally, the method may have a step of washing the base part before or after separation in a washing bath according to Oekotex and REACH standards, to ensure sufficient hygienic conditions.

The curving step (b) and the separating step (c) can be performed sequentially or simultaneously.

The method may also have a further step (d) of cutting the false eyelash rows to the desired length, in particular by mechanical cutting, by ultrasonic or radio frequency application or by heating. In this step (d), the eyelash rows are cut perpendicular to the median plane. They may be of different shapes, regular or irregular, for the right eye or left eye or the like.

The curving step (b), the separating step (c) and the cutting step (d) can be performed sequentially or simultaneously.

The production of false eyelash rows is simple, inexpensive and quick, and can be easily automated.

The method may also have the additional step of post-processing the artificial eyelashes to achieve dismantling of the free end of the artificial eyelashes. In this post-treatment step, it is possible to pass a row of false eyelashes over one or more cylinders, making it possible to apply friction to the artificial eyelashes. The cylinder may also be heated to facilitate disassembly. In this way, it is possible to obtain intersections of artificial eyelashes, which may be impossible to obtain by hand.

The first warp and the second warp may be made of a thermoformable material. Artificial eyelashes, and in particular weft yarns, may be made of thermoformable materials.

In a variant or additionally, the first warp and/or the second warp can be made of a heat-shrinkable material. The heat-shrinkable nature of the first warp and/or the second warp may allow for a fanning effect of the artificial eyelashes. The first warp and the second warp may have heat-shrinkage properties with different shrinkage.

The method may have at least the step (e) of activating the thermally fusible warp or multi-strand warp strand to secure the stitches of the base portion.

This activation step (e) may in a variant take place after one or more of the steps (b), (c) and/or (d) mentioned below.

Next, the assembly is cleaned.

The curving step (b) may preferably take place after the knitting step (a). This curving step (b) may take place simultaneously with or before one or more of the steps (c), (d) and/or (e) mentioned above or below, or in a variant after it. In particular, steps (b) and (c) can be simultaneous or, in a variant, successive, preferably step (b) occurs before step (c) or, in a variant, step (c) is followed by step (b) ) can occur later.

The median plane may be a plane of symmetry between the two base portions. The separation can take place in particular in the median plane or, in a variant, in a plane parallel to one of the base parts, close to the latter, for example at the same height as said base part.

The method may also have a further step (d) of cutting the false eyelash rows to the desired length, in particular by mechanical cutting, by ultrasonic or high-frequency application or by heating. In this step (d), the eyelash rows are cut perpendicular to the median plane.

The separation step (c) and the cutting step (d) may be performed simultaneously or sequentially.

It is possible to use a cutting tool to carry out the curving step (b), the separating step (c) and/or the cutting step (d).

The separation can take place in particular in the median plane or, in a variant, in a plane parallel to one of the base parts, close to the latter, for example at the same height as said base part.

artificial eyelashes blocking stitches

Another subject of the present invention, independently of or in combination with the above, is a row of false eyelashes fixed to the edge of the eyelid having (i) a base portion intended to be secured to the edge of the eyelid, and (ii) artificial eyelashes. is,

The base part has a first warp, in particular a chain stitch knitting warp, forming a stitch, the artificial eyelashes pass through the stitch of the base part, in particular the chain stitch of the first warp, and remain in the stitch of the base part without binding thereto.

In this way, artificial eyelashes at the stitches and blockage of the stitches can be obtained, preventing false eyelash rows from unraveling during handling and/or use. In this way, greater reassurance for the user is achieved, and an increase in the lifespan of the false eyelash row is achieved.

A further subject of the present invention is, independently or in combination with the above, a row of false eyelashes fixed to the edge of the eyelid, having (i) a base part intended to be fixed to the edge of the eyelid, and (ii) artificial eyelashes,

The base portion has a first chain stitch knit warp, and the artificial eyelashes pass through the chain stitch of the first warp and remain unbound in the chain stitch of the first warp.

The first warp may have a plurality of strands. This configuration with a plurality of strands makes it possible to increase the tightness of the stitches of the warp, in particular thanks to the greater internal friction of the yarns. The number of strands in the warp may be from 2 to 100 strands per warp, more preferably from 20 to 70 strands, for example about 34 strands. The cross-section of the strand may have a maximum dimension which may be between 4 μm and 0.3 mm, more preferably between 0.05 mm and 0.15 mm, for example about 0.07 mm. The cross-section of the strands may have a shape selected from the following list, but not limited to: circular, non-circular, oval, oval, polygonal, square, rectangular, triangular, hexagonal, lobed, trilobed, and multilobed. can have The cross-section of the strand may be hollow.

In one embodiment, the base part may have a second warp, in particular a chain stitch knit warp. Only the first warp may have a plurality of strands, or in a variant, the first warp and the second warp may each have a plurality of strands, so as to further increase the tightness of the stitch of the warp, and Robustness can be improved.

The first warp and the second warp may be interwoven.

Preferably, at least one warp or warp strand is thermally fusible. The thermally fusible yarn or strand may be activated after the knitting step to secure the stitches of the base portion. The term “activation” means an increase in the temperature of false eyelash rows that makes it possible to achieve partial or complete melting of a heat-soluble yarn or strand without damaging other non-heat-soluble yarns or strands. Melting of the heat soluble yarn or strand causes it to adhere to an adjacent yarn or strand, further enhancing the firmness of the false eyelash string.

The first and second warp or warp strands may include, for example, but not limited to the following list: a first thermally soluble synthetic material selected from polyolefins, PE, PP, PU, PA, PET, PBT, PES, PTFE, or polyolefins, PE, PP , PU, PA, PBT, PES, PTFE, heat-activatable adhesive or heat-activatable resin, TPU silicone, CoPA, CoPES, TPU, TPE, EVA (ethylene-vinyl acetate), polyolefin, polyethylene, It can be made from yarn coated with polypropylene, PA, PES, PVC.

The first and second warp or warp strands may be formed by stretching.

The first and second warp or warp strands may be surface treated to facilitate their retention.

The artificial eyelashes are formed by plastic deformation of the artificial eyelashes and/or bevels, in particular by applying a mechanical load in the presence of an energy stimulus which causes the material of the artificial eyelashes and/or bevels to be heated, in particular by applying ultrasound or radio frequency waves or by heating. It can be retained in the stitches of the base part. Heating may include application of steam.

The artificial eyelashes may be formed from a single weft yarn passed back and forth between the two base portions. In one embodiment, all artificial eyelashes in a row are formed from a single weft yarn. Thus, only one weft yarn is used to form all the artificial eyelashes. In a variant, the row may have a plurality of weft yarns, for example two weft yarns. Thus, it is possible to obtain a row of eyelashes with a more natural appearance, in which some artificial eyelashes intersect with other eyelashes.

The artificial eyelashes can be kept without binding to them in the stitches of the base part. The weft yarn does not form a stitch with the first warp.

The method may also have a step (e) of activating at least a warp or multi-strand warp strand that is thermally soluble to secure the stitches of the base portion. Activation may comprise heating, for example, in particular by means of a stove or heating roller or steam. The activation step (e) may preferably occur after the knitting step (a) and before one or more of the aforementioned steps (b), (c) and/or (d). This activation step (e) may, in a variant, occur after one or more of the steps (b), (c) and/or (d) mentioned above.

Next, the assembly is cleaned.

The curving step (b), the separating step (c) and the cutting step (d) can be performed simultaneously or sequentially.

The method may also have a step (f) of applying at least a plastic deformation to the artificial eyelashes and/or bevels, in particular by means of ultrasonic or radiofrequency application or by heating. Heating may include application of steam. Preferably, the step (f) of applying the plastic deformation takes place after the knitting step (a). This step (f) of applying the plastic deformation may take place before or in variants after one or more of steps (b), (c), (d) and/or (e) described above. The curving step (b), the separating step (c) and the cutting step (d) can be performed simultaneously or sequentially.

The shaping step (f) may make it possible to curve the base part which is intended to be fixed to the edge of the eyelid in order to give it the shape of the eyelid. This step (f) can for example be carried out simultaneously with step (b) of curving the artificial eyelashes or for example after all other steps.

1 shows a row of false eyelashes 10 intended to be fixed to the edge of the eyelid. This row 10 has (i) a base portion 12 intended to be fixed to the edge of the eyelid, and (ii) artificial eyelashes 14 .

The base portion 12 has a first chainstitch knit warp 16, and the artificial eyelashes 14 pass through the chainstitch without being bound thereto. Artificial eyelashes do not form chain stitches. The artificial eyelashes are bent into a U shape as shown, and the bottom of the U is held without knots at the first bevel 16 .

As shown in Fig. 2a, which is a customary schematic diagram, all artificial eyelashes 14 of the row 10 are formed from a single weft yarn T. Thus, only one weft yarn is used to form all the artificial eyelashes. In a variant, there may be a plurality of weft threads, especially in the case of yarns of different colors. The base portion 12 has a first chainstitch knit warp 16, and the weft yarn T passes through the chainstitch without being bound thereto. The weft yarn T passes back and forth between the two base parts 12 extending parallel and symmetrically to each other.

Figure 2a shows an assembly 20 for forming an artificial eyelid row to be fixed to the edge of the eyelid, in particular as described above. The assembly 20 has two base parts 12 , at least one of which is intended to be fixed to the edge of the eyelid, which are arranged parallel to each other and symmetrically with respect to the median plane P.

Assembly 20 also has artificial eyelashes 14 formed from a single weft yarn T passed back and forth between the two base portions 12 .

The weft yarns are disposed substantially perpendicular to the base portion. The weft yarn is cut between the two base parts, in particular at the median plane P, which is intended to separate the base parts 12 and thus form two rows of false eyelashes. The artificial eyelashes can be distributed regularly over the base part, in particular, for example always arranged at the same regular intervals. The weft yarn is not cut between the two base parts in the median plane P, but can be cut close to one of the two base parts. In this case, only one row of false eyelashes can be obtained.

2b , the assembly has three base parts 12 which are arranged parallel to each other and symmetrically with respect to the median plane P. The median plane can for example pass through the central base part, the two other base parts being arranged on either side of the central base part parallel and symmetrically to each other with respect to the median plane. In this case, there are two weft yarns T, a single weft yarn is passed back and forth between the two base parts.

In this variant embodiment, the three base parts are parallel to and close to one of the base parts, for example in a first separation plane P' flush with said base part and parallel to one of the base parts and the latter in a second separation plane P'' close to, eg flush with, the base part. In the example shown, the base portion under discussion is the central base portion.

In the assembly 20 of Figure 2a, each base portion 12 has a first chainstitch knit warp 16, the weft yarns T passing through the chainstitch without being bound thereto. Weft yarns do not form chain stitches. The weft yarn does not form a stitch with the first warp.

The first warp 16 of the base part 12 forms a closed chain stitch in the example shown. In a variant or additionally, the first warp forms an open chain stitch.

In the embodiment just described, the row has only one first slope 16 .

In one variation, and as shown in the embodiments of FIGS. 3A-5B , the base portion 12 can have a second chainstitch knit warp 18 . The artificial eyelashes 14 pass through the chain stitch of this second warp 18 without being tied thereto. In the assembly 20 of FIGS. 3A-5B , each base portion has a second chainstitch knit warp 18 , the weft thread passes through the chain stitch without being bound thereto. The first warp 16 and the second warp 18 may be interwoven.

The second warp may form a closed or open chain stitch.

3A and 3B, the first and second warps each form a closed chain stitch. The closed chain stitches are arranged symmetrically with respect to each other.

3C and 3D , the first and second warps each form closed chain stitches, which all overlap, meaning that they each follow exactly the same path. Further, the first and second warps each form a closed chain stitch.

In one variant, as shown in Figures 4a and 4b, the first warp forms a closed chain stitch and the second warp forms an open chain stitch.

In another variant, and as shown in FIGS. 5A and 5B , the first and second warps each form an open chain stitch.

In the embodiments just described, the row has only one weft yarn. It may for example have two of them, as illustrated by way of example in FIGS. 5C and 5D . The second weft yarn T', in this example, does not pass through all the chain stitches of the warp. Further, the second weft yarn T' intersects the first weft yarn T in various places. Thus, advantageously, it is possible to form a row of eyelashes having a more natural appearance, such as where some eyelashes intersect with other eyelashes.

The embodiment of Fig. 10 is similar to the embodiment of Fig. 3B, with the following differences. In the embodiment of FIG. 10 , the base portion 12 has additional yarns 24 interwoven with the first chainstitch knit warp 16 and the second chainstitch knit warp 18 . In particular, there are two additional threads 24 , one on each base part 12 .

The assembly 20 can be obtained by a knitting machine 30 , as shown in FIG. 6 . The knitting machine 30 has a compound needle 32 .

The compound needle 32 is formed of a body 33 and a sliding element 34 . The body 33 is composed of a butt 33a, a stem 33b and a hook 33c. The sliding element 34 consists of a butt 34a and a stem 34b. The sliding element can slide inside the stem of the body to close and open the hook 33c of the needle. Thus, the body of the needle and the sliding element move independently and in a synchronized manner.

Knitting machine 30 does not have a latch needle, in particular with a latch articulated to the stem, and has no sinker.

The knitting machine 30 has a yarn guide 35 for depositing the weft yarn T for forming the artificial eyelashes. This thread guide moves from right to left and left to right over the compound needle 32 .

The knitting machine 30 also has a first guide bar 36 for feeding the first warp 16 . This first guide bar 36 moves from right to left and from left to right, and from top to bottom and from bottom to top to rotate around the compound needle. The left-to-right movement may vary depending on whether warp 16 is intended to be knitted with an open or closed chain stitch.

Finally, the knitting machine 30 has a second guide bar 38 for feeding a second warp 18 . This second guide bar 38 moves from right to left and from left to right, and can deposit a second slope in the hook 33c of the compound needle. This second warp 18 makes it possible to better fix the first warp 16 , thereby making it difficult to untie the chain stitch of the base part. The nits thus obtained can be unwound.

Now, a method for manufacturing false eyelash rows will be described.

In a first step, two base parts 12 , which are intended to be fixed at least one on the edge of the eyelid, arranged parallel to and symmetrically with each other with respect to the median plane P, and between the two base parts An assembly 20 having artificial eyelashes 14 formed from a single weft yarn T extending back and forth is knitted by means of a compound needle.

The knitting is such that each base portion has a first chainstitch knit warp 16 and a second chain-stitch knit warp 18, the weft threads pass through the chain stitch without being bound thereto, and the weft yarns do not form a chain stitch. is carried out

It is possible to use the same cutting tool and/or the same anvil to carry out the separation step (c) and the cutting step (d). The cutting tool 10 is configured to allow the application of mechanical cutting, ultrasonic or radio frequency or heat.

In one variant embodiment, the weft yarn is held in the stitches of the base portion without binding thereto, so as to block the stitches in the stitches and the artificial eyelashes.

To this end, the first warp may have a plurality of strands, the second warp may have a plurality of strands, and/or the first and second warp may each have a plurality of strands.

In one embodiment, at least one warp or warp strand may be thermally fusible. The thermally fusible yarn or strand may be activated after the knitting step to secure the stitches of the base portion.
