Umshini wezipikili we-coil uwuhlobo lwemishini yokukhiqiza ezenzakalelayo, esebenza ngochungechunge lwezinqubo ezizenzakalelayo, okuhlanganisa ukuphakela, ukugoqa, ukusika nezinye izinyathelo, ukufeza ukukhiqizwa okuphumelelayo kwezipikili eziqediwe.Lo mshini wezipikili wekhoyili uyimishini yokushisela okuzenzakalelayo enemvamisa ephezulu futhi ijubane eliphezulu. Beka isipikili sensimbi ku-hopper ukuze uzibeke ngokuzenzakalelayo, idiski lokudlidliza ihlela ukuhleleka kwesipikili ukuthi ingene endaweni yokushisela bese yenza izinzipho zohlelo lomugqa, bese ucwilisa isipikili kupende ukuze ugweme ukugqwala ngokuzenzakalelayo, yome futhi ubale ngokuzenzakalelayo ukuze ungene ngaphakathi. i-roll-shape (uhlobo oluyisicaba kanye nohlobo lwe-pagoda). Sika ngokuzenzakalelayo ngokuya ngesethi yenombolo yomqulu ngamunye.
