Total Claims: 5
Claim 1
Independent Claim
157 words
Apparatus for severing the belly flaps of fish comprising: at least one severing knife; conveying means for conveying beheaded fish past said at least one severing knife with rumps thereof trailing and in cycles defining substantially equal distances with respect to said rumps; a pivoted crank for supporting said at least one severing knife at a position with respect to said conveying means; non-resilient means for locking said pivoted crank in a predetermined position whereby said at least one severing knife is locked in a predetermined position; means for applying a resilient force to said pivoted crank varying in relation to a position of said rumps of said fish; and means for unlocking said pivoted crank in response to a head end of said fish reaching a predetermined position with respect to said at least one severing knife whereby said resilient force at the time of unlocking is variable in dependence on a length of said fish.
Claim 2
Dependent Claim
