I-Projectile loom isho indwangu yokweluka esebenzisa i-weft clamp efana neshidi (ebuye ibizwe ngokuthi "i-projectile") ukwethula i-weft eshedini. Ijubane eliphezulu lokufaka i-weft, ukuguquguquka okuqinile ezinhlobonhlobo zendwangu, kungaluka izindwangu ezibanzi, nomsindo ophansi womshini.

I-projectile loom inejubane eliphezulu lokufaka i-weft kanye nokuvumelana okuqinile nezinhlobo zendwangu. Ingakwazi ukuluka izindwangu ezibanzi ngomsindo ophansi womshini. Kunezinhlobo ezimbili zama-projectile looms: i-PU ne-PS. Ububanzi bokusebenza buyi-220 ~ 545 cm. Ihlukaniswe yaba umbala owodwa kanye multicolor. Ingaluka izindwangu ezihlanzekile nezihlanganisiwe ezifana nekotini, uvolo kanye nemicu yamakhemikhali. Njengokufakwa kwe-dobby kanye ne-jacquard yokuchitha indlela, singakwazi ukuluka izindwangu zephethini ezincane nezinkulu. Ngo-1933, u-German R. Rothman waqala ukuphakamisa ukufakwa kwe-projectile weft; ngo-1934, i-Swiss Sulzer Company yathuthukisa i-projectile loom, eyafakwa ekukhiqizeni ukuhweba ekuqaleni kwawo-1950. Ama-looms we-projectile ahlukile kuma-shuttle looms ajwayelekile ezingxenyeni ezintathu: ukufakwa kwe-weft, ukushaya phezulu kanye ne-selvedge. Ukufakwa kwe-weft kwenziwa ngebhokisi le-shuttle, umshini wokukha i-torsion shaft, ujantshi we-shuttle guide, i-shuttle box kanye nendlela yokudlulisa i-projectile. Indwangu ngayinye ifakwe ama-projectiles amaningana, futhi izintambo ze-weft zingeniswa eshede kusukela ohlangothini lokuphakelayo lwe-weft ngokulandelana. Amandla e-shuttle avela emandleni anwebekayo angaba namandla agcinwe lapho i-torsion shaft isontekile, futhi amandla asele amuncwa isibhafa se-hydraulic.

I-projectile ihamba eduze nomzila wesitimela. Ngemuva kokuthi ingene ebhokisini le-shuttle futhi ibhuleki, ibuyiselwa endaweni yokuqala ngomshini wokudlulisa ngaphansi kweshede. Ukushaya kusebenzisa indlela ye-conjugate cam. Lapho i-sley ithuthuka, ujantshi we-shuttle guide uphuma eshede futhi uya phansi endaweni yendwangu ukuze uqedele isenzo sokushaya; lapho i-sley ihlehla futhi iphumule, isitimela se-shuttle guide sifakwe eshede, futhi i-projectile iqhubekela phambili eduze nomzila wesitimela we-shuttle ukwethula i-weft eshedini. Imishini egoqayo, esontekayo kanye ne-intermediate selvedge isetshenziswa ku-projectile loom ukuluka izindwangu ezinobubanzi obubodwa, ububanzi obuphindwe kabili noma ububanzi obuningi. Lapho weluka izindwangu zefiber zokwenziwa, idivayisi encibilikisa emaphethelweni isetshenziselwa ukulungisa izintambo ezisontekile. Kusukela ngawo-1970s, ama-projectile looms amukele kabanzi ama-accumulators we-weft, ukutholwa kwe-elekthronikhi kokumiswa kwe-loom namanye amadivaysi ukuze kuthuthukiswe ukukhiqizwa kwe-loom; ngasikhathi sinye, baphinde bahlola ngempumelelo ukusetshenziswa kwama-motor mechanical, pneumatic noma linear induction motors ukuveza umkhawulo owodwa noma womabili we-weft. Uhlaka lwe-Projectile olune-projectile kuphela nokufakwa kwe-weft okuhambisanayo.
