Abstract
Circlip making apparatus comprises three forming tools 2, 3, 4 equiangularly spaced about a mandrel axis 1a. A row of integral circlip blanks 6 are fed to the mandrel 1 through guide means 5 and blanks are cut from the row by blade 7 one by one before being bent into circlips around the mandrel 1 by advancement of the tools 2, 3, 4 radially of axis 1a. The row of blanks 6 is made from long flat wire stock and the stock is passed through work stations in which each blank is cut to tapered form and its cross-section planished between the ends so that it is adapted to a shape to be bent into a circlip without irregular distortion or buckling.
