A mechanism for locating and positioning cylindrical cores on a mandrel includes three spaced threaded rods driven in the same direction and having substantially identical threads. A chute is positioned above the space defined between the threaded rods, with the cores passing from the chute to a position in which the cores are supported on the threads. The threaded rods, during rotation, carry the cores in spaced relation onto a mandrel which is positioned between the threaded rods. The cores are located and positioned in a precise spaced relationship on the mandrel by the rotating threaded rods.
