Qhov txiaj ntsig loj tshaj plaws ntawm cov txhav rapier ntos weft kev kaw lus yog tias nws nquag xa cov xov paj xov rau qhov nruab nrab ntawm lub qhov ncauj weaving tsis muaj ib qho khoom coj. Lub nruj rapier ntos npog thaj tsam loj, feem ntau vim tias qhov dav ntawm lub vev xaib muaj qee qhov kev txwv.
Kev hloov pauv rapier ntos weft kev tso tawm muaj qhov muaj peev xwm yoog raws, qhov kev thov dav dav, thiab tus tes taw qhov ntxig yog qhov nce ntxiv, thiab qhov dav ntawm qhov weft yog 460cm.
Hauv 15 xyoos dhau los ntawm xyoo pua 20th, cov koos pij tawj hluav taws xob tau nkag mus rau hauv looms. Lub tshuab hluav taws xob microelectronics CAD-CAM tau siv dav, uas ua rau lub tshuab thev naus laus zis, cov ntaub ntawv siv tshuab thiab cov tshuab weaving tsim ua ke zoo meej. Ntau cov khoom siv hluav taws xob thiab tshuab ua ke nrog looms tau los ua ntaj. Cov khoom sib txuas ntawm loom, tshwj xeeb tshaj yog daim ntawv thov dav ntawm microelectronics ntawm rapier looms, suav nrog weft kev siv thev naus laus zis. Qee lub plahaum cov kab nkag tau zoo heev txhim kho, me me ntawm qhov loj me thiab lub teeb yuag.
Vim tias qhov kev thov dav dav ntawm cov thev naus laus zis thev naus laus zis, qhov nrawm thiab qhov cuam tshuam ntawm cov tshuab raj rapier tau hloov kho tau zoo heev. Hauv ntau qhov kev tso dej ntawm cov pob qij txhawm, xws li kev nkag mus hauv cov tshuab qij tes, cov kab txuas rau cov khaub ncaws rapier weft, cov kab dej tsis pub dej dav hlau thiab dej dav hlau kev ntsuas dej tsis sib haum, qhov ceev ceev tsis pub nkag siab ceev tseem yog qhov siab tshwj tsis yog rau lub dav hlau tsis pub dej dav hlau. Hauv 50 xyoo dhau los ntawm xyoo pua 20, tus menyuam kis tau tus mob loj sai dhau los ua kev nce qib. Thaum xyoo 1995 Milan thiab 1999 Paris tso rau neeg saib, qhov tseeb kev sib tw qib siab tshiab tau coj los tshaj tawm rau ntiaj teb.
