Makina Ozungulira Oluka

Ma tubular preforms amapangidwa pamakina oluka ozungulira, pomwe mawonekedwe athyathyathya kapena 3D, kuphatikiza kuluka kwa tubular, nthawi zambiri amatha kupangidwa pamakina oluka.

Tekinoloje yopanga nsalu zophatikizira ntchito zamagetsi mu

Kupanga nsalu: kuluka

Kuluka kozungulira ndi kuluka ndi njira ziwiri zoyambirira za nsalu zomwe zimaphatikizidwa ndi mawu oti knitwear (Spencer, 2001; Weber & Weber, 2008). (Gulu 1.1). Ndi njira yodziwika kwambiri yopangira nsalu pambuyo poluka. Makhalidwe a nsalu zoluka amasiyana kwambiri ndi nsalu zopangidwa ndi nsalu chifukwa cha mawonekedwe osakanikirana a nsalu. Kusuntha kwa singano panthawi yopanga ndi njira yoperekera ulusi ndizomwe zimayambitsa kusiyana pakati pa kuluka kozungulira ndi kuluka kwa warp. Ulusi umodzi ndi zonse zomwe zimafunikira kuti mupange zosokera mukamagwiritsa ntchito njira yoluka weft. Pamene singano zoluka zimasunthidwa nthawi imodzi, singanozo zimasunthidwa paokha. Chifukwa chake, zinthu za fiber zimafunikira ndi singano zonse nthawi imodzi. Chifukwa cha izi, matabwa amagwiritsidwa ntchito popereka ulusi. Zoluka zozungulira, zoluka za Tubular zoluka, zoluka zathyathyathya, ndi nsalu zolukidwa bwino ndizomwe zimakhala zofunikira kwambiri.

Malupu amalumikizana mzere pambuyo pa mzere kupanga mapangidwe a nsalu zoluka. Kupanga lupu mwatsopano pogwiritsa ntchito ulusi woperekedwa ndi udindo wa mbedza ya singano. Lupu lapitalo limazembera pansi pa singano pamene singano ikukwera mmwamba kuti igwire ulusi ndikupanga chipika chatsopano (mkuyu 1.2). Singano imayamba kutseguka chifukwa cha izi. Tsopano popeza mbedza ya singano yatseguka, ulusi ukhoza kugwidwa. Lupu lakale lochokera ku bwalo lolukira lapitalo limakokedwa kudzera mu lupu lopangidwa mwatsopano. Singano imatseka panthawiyi. Tsopano kuti chipika chatsopanocho chikadali cholumikizidwa ku ndowe ya singano, chipika chapitacho chikhoza kumasulidwa.

Sink imagwira ntchito yofunika kwambiri popanga zovala zoluka (Mkuyu 7.21). Ndi mbale yopyapyala yachitsulo yomwe imabwera mosiyanasiyana. Ntchito yayikulu ya sink iliyonse, yomwe imayikidwa pakati pa singano ziwiri, ndikuthandizira kupanga lupu. Kuonjezera apo, pamene singano imayenda mmwamba ndi pansi kuti ipange malupu atsopano, imasunga malupu omwe anapangidwa mu bwalo lapitalo pansi.
