A folding control apparatus for left and right lateral pieces of slice food is provided, such that when the slice food is moving forward on a transfer belt surface, the slice food is attached and positioned on the transfer belt surface; and a left and right lateral pieces of the slice food are blown by high-pressure air at a different time sequence to be folded and overlapped with respect to each other, so as to cover a stuffing strip on a surface of the slice food for forming a food enclosing material, thereby further simplifying a structure for folding the slice food to reduce a manufacturing cost and lower noise.
