Abstract: A crimping and cutting assembly includes a first roller engaged with a second roller including a honeycomb pattern of polygonal crimping and cutting members. Various transversely spaced, internally filled dough ropes are fed between the first and second rollers, causing each rope to be continuously crimped and cut at longitudinally spaced locations to create multi-sided food products, specifically polygonal food products having two to six crimped and cut sides. The ropes can permissibly shift or wander laterally during production, resulting in slightly different size or shape food products, while the honeycomb pattern acts to re-align the ropes so as to be tolerant to the ropes wandering while still preventing puncturing of the ropes which could lead to loss of filling and extended production downtime.
