  • Patent number: 6729217
    Abstract: This device comprises a frame carrying means for conveying blanks according to a substantially plane path and two parallel shafts (10, 11), which are mounted so as to be rotatable on both sides of the plane of said path and comprising tool supports (19a, 19b, 20a, 20b) for inducing a shearing between the adjacent edges of a cutting line during their displacement, in order to break nicks on the cutting line. Each parallel shaft (10, 11) comprises at least one tool support (19a, 19b, 20a, 20b) for connecting the shearing tools to said respective shafts (10, 11) and means for angularly (10a, 11a) and longitudinally positioning these tool supports (19a, 19b, 20a, 20b) on said respective shafts (10, 11).
