Ipuleti lokuhlobisa elinyathela ngezitembu ezisezingeni eliphezulu: ipuleti lokuhlobisa elinyathela ngezitembu eliphezulu likupuleti lensimbi engagqwali ngokucutshungulwa kwemishini yomshini, ukuze ubuso bepuleti bubonakale bu-concave - iphethini ye-convex.
Isibonelo: okusanhlamvu okuncane kwesheke, okusanhlamvu kwesheke ledayimane, iphethini yombala, okusanhlamvu kwesiyingi sombala nokunye.
Ihlukile enqubweni ye-etching board, ibhodi lembali yokuhlobisa izinga eliphezulu lokugxiviza kuyindlela yokucubungula ngokomzimba, indawo engaphezulu izoba nokuzwakala kwe-concave ne-convex, umuzwa ongcono wezinhlangothi ezintathu nokumelana nokungqubuzana, okuvame ukusetshenziselwa ukwenza ipuleti lomnyango wensimbi engagqwali, i-anti-slide yensimbi engagqwali, ipuleti letafula lensimbi engagqwali.
