Bikpela rop bilong masin em wanpela kroset,
A gauze piece, a sub-yarn piece, a spheroid sheet, a tablet and a yarn guide. Crochet fixed in the needle bed, for compound movement. The bending pieces are arranged in the needle every two needles, and the pushing pieces are pushed by the inclined surface of the pushing plate, thereby pushing the bending pieces to bend the yarns in sequence. The gauze i stap namel long ol gusset na em i draivim long rot bilong as bilong sinker kava, na ol i brukim rop bilong bent i bruk. De-sproket em i ekstensen bilong olpela koil taim nil i go daun na holim olpela koil.
