Holes are removed from nested product patterns by conveying products on a conveyance mechanism ( 12 ) through an infeed section ( 14 ) in nested pattern streams (a 1 , a 2 , b 1 , b 2 ), into a narrowing section ( 24 ) of a width less than one and one half the product diameter. After the narrowing section ( 24 ), the product streams (a 11 , a 21 , b 11 , b 21 ) enter into an expansion section ( 44 ) where products move into a side-by-side product stream (a 12 , a 22 , b 12 , b 22 ). Thereafter, nested product streams (a 13 , a 23 , b 13 , b 23 ) are formed, which can be combined to form nested product streams (A, B) which can be further processed as desired.
