A machine for automatically threading a plurality of filaments through toroidal cores useful in manufacturing magnetic core memory arrays for use in digital data processing equipment. The cores are held on edge in a plurality of rows and columns with their apertures aligned and the filaments pass between a pair of drive rollers and are thereby advanced through the aligned apertures. Cooperating with the drive rollers are motor driven cams which impart a back-and-forth rotational motion about the axes of the filaments as well as a pulsating step-by-step forward motion into the core array.
