by a pivoted having a permanently-threaded eye

47/

the path of the needle being modified by cams, linkages, or other means

by a forked needle pushing loop of weft through shed

47/

wherein single picks of weft thread are inserted, i.e. with shedding between each pick (D03D 47/27 takes precedence) [3]

47/

by a gripper needle taking the end of the weft through the shed

47/

by a gripper needle entering the shed empty and drawing the weft as it retracts
