Method and Device for Treating, Especially Cutting, a Shaped Flexible Textile, Especially a Bra

Abstract

This invention relates to a method for treating a flexible elastic textile element comprising at least one shaped part which must be partially treated and is surrounded by a plane part. According to the invention, the flexible textile element is gripped in at least two points of the plane part surrounding the shaped part which must be treated; the part gripped between two points is removed in such a way as to essentially flatten the shaped part gripped between the two points; and the removed gripped part is flattened.

1 . A treatment method for a supple elastic textile piece, said supple elastic textile piece comprising at least one shaped portion surrounded by a plane portion, wherein said plane portion is gripped at least two points being stretched to form a stretched portion between said two points so as to approximately flatten said shaped portion surrounded by said plane portion said stretched portion being treated while it is flat. 
   
   
       2 . The method according to  claim 1 , wherein as the piece is stretched and flattened, an air jet is applied to said shaped portion to move said shaped portion to prevent interference with the treatment. 
   
   
       3 . The method according to  claim 1 , wherein the piece is gripped at three points by a central clamp and two side clamps approximately defining a common plane. 
   
   
       4 . The method according to  claim 3 , wherein said gripped points are moved apart by displacing the central clamp with respect to the side clamps. 
   
   
       5 . The method according to  claim 4 , wherein said gripped points are moved apart by tipping the central clamp with respect to the side clamps, outside the common plane of the clamps. 
   
   
       6 . The method according to  claim 1 , wherein the flat treatment is a cut out. 
   
   
       7 . The method according to  claim 6 , the cut out is done using ultrasounds. 
   
   
       8 . A treatment device for a supple elastic textile piece, said piece comprising at least one shaped portion surrounded by a plane portion, wherein the device comprises a gripping device to grip the piece at least two points on the plane portion surrounding the shaped portion to be treated, means for stretching the piece gripped between these two points so as to approximately flatten the shaped portion gripped between the two points, and means for treating the gripped stretched portion while it is flat. 
   
   
       9 . The device according to  claim 8 , further comprising a blower nozzle associated with the means for treating, to blow an air jet onto the shaped portion to be treated. 
   
   
       10 . The device according to  claim 8 , wherein said gripping device is a three-point device comprising a central clamp and two side clamps approximately defining a common plane. 
   
   
       11 . The device according to  claim 10 , wherein said central clamp ( 21 ) is installed free to tip so that it can be brought out of the plane common to the clamps. 
   
   
       12 . The device according to  claim 10 , gripping device is a five-point device comprising two end clamps. 
   
   
       13 . The device according to  claims 8 , further comprising an ultrasound cutting roller.
