Abstract: Apparatus for looping tying material about the eye of a button comprising a device for supporting a button having an eye or eye shank extending outwardly from a reverse side thereof and a device for passing a doubled length of tying material through the eye of a button together with apparatus for looping one of the two strands of the doubled length of tying material about the eye or eye shank of the button. The looping apparatus comprises a shoulder formed on a rotatable semi-conical member for engaging one strand of the doubled length of tying material beyond where the tying material passes through the eye of the button. The semi-conical member is rotatable about an axis which is inclined relative to the axis of the button while the apparatus is in use.
