A vibratory bar feeder has a magazine storing a supply of bars and a device for dropping the bars one at a time from the magazine into a trough below the magazine and extending beyond the magazine toward a bar-working machine. The inside of the trough is covered with a pile material having flexible filaments inclined from the vertical toward the bar-working machine, the trough is vibrated in a generally reciprocal motion in the general direction of the inclination of the filaments which are sufficiently resilient to flex under the bars during upward movement of the trough to translate the vibratory motion into feeding speed and force moving the bars toward the bar-working machine.
