Mu 1954, Philippe-Guy Woog, dokotala wa ku Switzerland, anapanga mswachi wamagetsi wa odwala omwe amavutika kusuntha manja awo.Sakanatha kuganiza kuti zikanakhala zophweka bwanji kupanga burashi yamagetsi yamagetsi patapita zaka zingapo.

Ambiri mwa misuwachi yamagetsi yomwe imagwiritsidwa ntchito tsopano ndi ya ma acoustic wave electric brushages.The lamayimbidwe yoweyula pano sizikutanthauza kudalira akupanga kuyeretsa mano, koma kugwedera pafupipafupi mswachi wafika pafupipafupi lamayimbidwe yoweyula.

Panthawi yogwiritsira ntchito mswachi wamagetsi, galimoto yothamanga kwambiri imatumiza mphamvu ya kinetic ku shaft yoyendetsa, ndipo mutu wa burashi umatulutsa kutsika kwafupipafupi kwa oscillation perpendicular to chogwirira.

Chigoba ndi chigawo chothandizira cha mswachi wamagetsi amapangidwa ndi pulasitiki ya ABS, ndiye kuti, utomoni.Zida zamakina zomwe zimafunikira pa chipolopolo ndi chigawo chothandizira pakupanga ndi makina omangira jakisoni.Ndi pulasitiki ya thermoplastic kapena thermosetting yogwiritsa ntchito nkhungu yopangira pulasitiki, zopangidwa ndi pulasitiki mumitundu yosiyanasiyana ya zida zomangira zazikulu.

Chinthu chachikulu cha mswachi wamagetsi ndi injini ndi bristles.Ziphuphu pa mswachi wamagetsi zimayikidwa ndi makina a tufting.

Njira ya tufting ndiyosangalatsa kwambiri.Choyamba, pindani ma bristles pakati, ndiyeno muwaike mu poyambira ndi makina othamanga kwambiri, kuti bristles ndi mutu wa burashi zigwirizane.Kenako, chepetsa bristles monga momwe amafunira molingana ndi mawonekedwe a mutu wa burashi.Mphepete mwazitsulo zowonongeka zimakhala zovuta kwambiri ndipo zimafunika kuzunguliridwa ndi kupukutidwa ndi makina opera mpaka micrograph yapamwamba ya bristle imodzi yozungulira.

Mukamaliza ntchito zingapo, burashi yamagetsi yamagetsi idzayesedwa ndi tester yopanda madzi ndikuwunika kachitidwe kambiri, kenako idzagwiritsidwa ntchito pamakina opaka ndikulowetsa ulalo wa blister ndi kulemba.
