Holes are removed from nested product patterns by conveying products on a conveyance mechanism () through an infeed section () in nested pattern streams (a, a, b, b), into a narrowing section () of a width less than one and one half the product diameter. After the narrowing section (), the product streams (a, a, b, b) enter into an expansion section () where products move into a side-by-side product stream (a, a, b, b). Thereafter, nested product streams (a, a, b, b) are formed, which can be combined to form nested product streams (A, B) which can be further processed as desired.
