A method for processing fish fillets by separating a superficial layer of said fillet comprising the skin and an apparatus for performing this method is described. The apparatus essentially comprises a conveying roller (3) for carrying the fish fillets skin-side down and a pressing shoe (6) which, with its pressing surface (7) forms a conveying gap with the conveying roller (3). At the input side of the conveying gap, the pressing shoe (6) is formed as a first knife (11), above which a driven second knife (16) is arranged in a knife guide (14). With this arrangement it is, possible to detach a further superficial layer apart from the skin layer and to collect these two layers separately.

Why it's free to use
- Filed August 29, 1994 and granted March 30, 1999. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended August 29, 2014.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by August 29, 2016.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
