Method for producing noble metal meshes on flatbed knitting machines

Abstract

A method for producing a two-layer noble metal mesh on a flatbed knitting machine which has a first and a second needle bed. The method comprises: providing at least one wire containing noble metal; and knitting the noble metal mesh. The first and second layers of the noble metal mesh are knitted simultaneously on the first and second needle bed, and a supporting mesh is knitted on the first and second needle bed using a supporting thread. An abutting edge of the supporting mesh is connected to the two layers of the noble metal mesh via connecting stitches and knitted via both needle beds in the knitting rows containing the connection.

1 . A method for producing a two-layer noble metal mesh on a flat-bed knitting machine, the flat-bed knitting machine comprising a first and a second needle bed, the method comprising the steps of:
 providing at least one noble-metal-containing wire,   providing at least one noble-metal-free support thread,   knitting a first layer of the noble metal mesh on the first needle bed and a second layer of the noble metal mesh on the second needle bed,   the first layer comprising the abutting edges S 11  and S 12  and the second layer comprising the abutting edges S 21  and S 22 , the abutting edge S 11  at least partially abutting the abutting edge S 21  and the abutting edge S 12  at least partially abutting the abutting edge S 22 ,   knitting a support mesh on the first and second needle bed using the at least one noble-metal-free support thread, the support mesh comprising an abutting edge SH and an edge KH opposite the abutting edge, the abutting edge SH abutting an abutting edge S 11  and S 21  of each of the two layers of the noble metal mesh,   all of the knitting processes taking place simultaneously,   wherein the abutting edge SH of the support mesh is connected to the respective abutting edges S 11  and S 21  of the two layers of the noble metal mesh via at least one knit stitch, and   wherein the support mesh is knitted with connecting stitches from both needle beds in the knitting rows on which the abutting edge SH of the support mesh is connected to the respective abutting edges of the two layers of the noble metal mesh S 11  and S 21 .   
     
     
         2 . The method according to  claim 1 , wherein the at least one noble-metal-containing wire consists of platinum, a platinum alloy, palladium, or a palladium alloy. 
     
     
         3 . The method according to  claim 1 , wherein the first and the second layer of the two-layer noble metal mesh are knitted from a noble-metal-containing wire or noble-metal-containing wires of the same composition. 
     
     
         4 . The method according to  claim 1 , wherein the first and the second layer of the noble metal mesh are knitted from a noble-metal-containing wire or noble-metal-containing wires of the same diameter. 
     
     
         5 . The method according to  claim 1 , wherein the first and the second layer of the noble metal mesh are knitted in the same knitting pattern. 
     
     
         6 . The method according to  claim 1 , wherein the first and the second layer of the noble metal mesh are congruent. 
     
     
         7 . The method according to  claim 1 , wherein the first layer and the second layer of the two-layer noble metal mesh are at least partially connected at their abutting edges by at least one connecting knit stitch. 
     
     
         8 . The method according to  claim 1 , wherein the abutting edge SH of the support mesh has the same length as the abutting edges S 11  and S 12  of the first and second layers of the two-layer noble metal mesh. 
     
     
         9 . The method according to  claim 1 , wherein the shape of the support mesh correlates with the shape of the first and second layers of the two-layer noble metal mesh. 
     
     
         10 . The method according to  claim 1 , wherein the abutting edge SH of the support mesh is connected over its entire length to the respective abutting edges S 11  and S 21  of the first and second layers of the two-layer noble metal mesh. 
     
     
         11 . The method according to  claim 1 , wherein the support mesh surrounds at least 50% of the sides of the first and second layers of the two-layer noble metal mesh. 
     
     
         12 . The method according to  claim 11 , wherein the support mesh comprises a plurality of regions. 
     
     
         13 . The method according to  claim 12 , wherein the method comprises a further step in which the support mesh is removed. 
     
     
         14 . The method according to  claim 1 , wherein the method comprises a further step in which a connecting stitch or connecting stitches between the first and second layers of the noble metal mesh are removed on one side.
