A shearing system is adapted to remove a portion of product having a main product length moving along a line. The system comprises: a pair of parallel shafts arranged approximately normal to the line; a hub assembly carried by the pair of a parallel shafts and comprising a pair of first cutting blades in a first cutting zone adjacent to one side of the line; a drive assembly for continuously rotating the shafts in opposing directions; and a switching assembly for deflecting the product from the line along a path bypassing the first cutting zone and for sequentially traversing the product. The hub assembly can further comprise a pair of second cutting blades in a second cutting zone separated by the first cutting zone by a neutral zone without cutting blades. Also, the hub assembly can comprise multiple pairs of third cutting blades in a third cutting zone bordering the second cutting zone.
