Claim 10
Dependent Claim
57 words
A device as recited in claim 6 wherein said cam means is stationarily fixed and wherein said cutting jaws are mounted on a movable carriage disposed such that said jaws are aligned for engagement with said stationary cam means, whereby the selective movement of said carriage results in the actuation of said jaws by said cam means.
Claim 11
Dependent Claim
42 words
