Abstract of the Disclosure The present invention discloses an apparatus for slicing a food product such as a potato into helical strips such as curlicue potato fries. The potatoes are pumped with water by a centrifugal food pump to a tapered elastic tubular delivery tube. The tube expands as the potato progresses along the tube. The delivery tube allows the potato to be gently forced against a circular rotating cutting head assembly. The cutting head assembly cores the potato, scores concentric cuts and then slices the potato to produce helical cut segments.

Why it's free to use
- Filed January 2, 1990 and granted September 1, 1992. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended January 2, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by January 2, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
