Abstract
A latched needle having a hook portion and associated pivoted latch, the hook portion being connected to a shank portion leading to a butt portion for engagement by an operating cam. Proceeding along the shank portion from the latch pivot towards the butt portion, the shank portion has an increase in depth over part of its length and in respect of this part the transverse cross-section is modified to present asymmetry about a median plane parallel to the side faces of the shank portion as by cutting part of the thickness of the shank portion away over part of the depth to produce a stepped shape in transverse cross-section.
