Manufacturing method for row of artificial eyelashes

Abstract

A method for manufacturing a row of artificial eyelashes, having at least the two following steps of: (a) knitting an assembly for forming rows of artificial eyelashes to be fixed to the edge of an eyelid, this assembly having at least two base parts, at least one of which is intended to be fixed to the edge of an eyelid, which are disposed parallel and symmetrically to one another with respect to a median plane (P), and false eyelashes, each base part having a first warp thread forming stitches, in particular a chain-stitch knitted warp thread, and (b) curving the row of artificial eyelashes and/or the base part and/or the false eyelashes by applying a mechanical load in the presence of an energy stimulus causing the material of the false eyelashes to heat up, in particular by applying ultrasound or high frequencies or by heating.

1 . A method for manufacturing a row of artificial eyelashes, having at least the two following steps of:
 (a) knitting an assembly for forming rows of artificial eyelashes to be fixed to the edge of an eyelid, this assembly having at least two base parts, at least one of which is intended to be fixed to the edge of an eyelid, which are disposed parallel and symmetrically to one another with respect to a median plane (P), and false eyelashes, each base part having a first chain-stitch knitted warp thread forming stitches, the false eyelashes passing through the chain stitches without being tied thereto, and a second chain-stitch knitted warp thread forming stitches, the false eyelashes passing through the chain stitches without being tied thereto, wherein the first and second warp threads are interwoven, and   (b) curving the row of artificial eyelashes and/or the base part and/or the false eyelashes by applying a mechanical load in the presence of an energy stimulus causing the material of the false eyelashes to heat up.   
     
     
         2 . The method of  claim 1 , wherein, in step (b), the energy stimulus involves the application of ultrasound. 
     
     
         3 . The method as claimed in  claim 1 , wherein, in step (b), the energy stimulus involves the application of high frequencies. 
     
     
         4 . The method as claimed in  claim 1 , wherein, in step (b), the energy stimulus involves the application of heating. 
     
     
         5 . The method of  claim 1 , further comprising (c) separating the two base parts ( 12 ) by cutting the weft thread (T) to form at least one row ( 10 ) of artificial eyelashes. 
     
     
         6 . The method of  claim 5 , further comprising (d) cutting the rows ( 10 ) of artificial eyelashes to the desired length. 
     
     
         7 . The method of  claim 6 , wherein a cutting tool is used to carry out separation step (c) and/or cutting step (d). 
     
     
         8 . The method of  claim 6 , wherein an anvil is used to carry out separation step (c) and/or cutting step (d). 
     
     
         9 . The method of  claim 6 , wherein one and the same cutting tool and/or one and the same anvil is/are used to carry out separation step (c) and/or cutting step (d). 
     
     
         10 . A cutting tool for implementing a method for manufacturing a row of artificial eyelashes, in particular as claimed in  claim 1 , said cutting tool being configured to allow the application of a mechanical cut, ultrasound or high frequencies or heating to an assembly for forming rows of artificial eyelashes to be fixed to the edge of an eyelid, this assembly having at least two base parts, at least one of which is intended to be fixed to the edge of an eyelid, which are disposed parallel and symmetrically to one another with respect to a median plane (P), and false eyelashes.
