Abstract
A machine for inserting foam cores within the coil springs of a mattress or similar device having a series of spiral coil springs. The machine has a series of hollow receptacles for accommodated the cores above and aligned with one row of coil springs of the mattress. Beneath the mattress, a series of grippers is located in alignment with the receptacles. When actuated, the grippers rise through the coil springs, grip the bottom of each foam core, and return through the coils, placing each core in the center of each of the coils of the row of coils. The mattress is then indexed, and the process repeated for the next row of coils.
