These shearing members are mounted for relative radial wobbling shearing movement. There are provided in the apparatus also means for keeping the cooperating cutting edges at a safe axial distance from one another to avoid, during operation, damage to them, said means at the same time allowing the shearing members to relatively move in all radial directions to achieve the wobbling shearing operation.
