Kwishishini loomatshini bokupakisha, kukho usetyenziso oluninzi lweeseli zomthwalo, uninzi lwazo luhlolo lobungakanani kunye nezikali zokuhambisa kunye nokuhlela. Ukusetyenziswa okuphambili kwezi zinzwa kukukhangela kwi-line yokungahambelani kobunzima, iindawo ezingekhoyo okanye imiyalelo ngexesha lokupakisha. Banikezela ngengxelo kwizixhobo zokupakisha ukuqinisekisa ukuba iimveliso ziyahlangabezana nemimiselo kunye neemfuno, ukwandisa ukusetyenziswa kwezinto eziphathekayo, kunye nokuphucula umgangatho wemveliso ngokubanzi. Imveliso ngokwayo yenziwe nge-conveyor yokulinganisa, umlawuli kunye ne-in-out material conveyor. Umthwalo wokulinganisa uxanduva lokuqokelela umqondiso wobunzima kunye nokuwuthumela kumlawuli ukuze kuqhutywe, ngelixa umqhubi we-infeed unoxanduva lokunyusa isantya semveliso kunye nokudala indawo eyaneleyo phakathi kwezinto. Emva koko, umthumeli wokukhupha udlala indima ebalulekileyo ekuthuthweni kweemveliso zovavanyo ukusuka kwindawo yokulinganisa kunye nokuphelisa naziphi na izinto ezineziphene. Ukuba ujonge olona hlobo lulungileyo lwenzwa, qwalasela iiseli zomthwalo wenqaku elinye, iiseli zomthwalo we-bellows okanye iiseli zomthwalo wohlobo lwe-S.
