Abstract
Abstract An oscillating feeding apparatus has an oscillating cup and a storage hopper. A rotatably driven separating disc is at the foot of the storage hopper and, at the lower edge of the storage hopper, there is provided an annular output opening which is closed by a flexible annular curtain. A separating disc defines a spiral path so that the parts are urged individually through the annular curtain into the oscillating cup.
