Abstract

A loaf feed apparatus for a food article slicing machine. The apparatus has at least a first conveyor driven by a hollow shaft and a second conveyor driven by a second shaft. The second shaft independently operates within said hollow shaft. The hollow shaft and the second shaft are driven by independent drive sources. The apparatus also includes at least one lower conveyor driven by a drive roller having a outer diameter and a recessed diameter where the drive belt is connected around the recessed diameter and the conveyor belt is connected around the outer diameter. The drive belt operates within an area defined by the first conveyor belt. The apparatus also has a loaf gate for separating a slicing station from the loaf feed apparatus.

Claims
