<p>A shearing apparatus ( 1 ) for shearing a plate member ( 2 ) is provided with a pair of shearing rollers ( 20, 20 ) opposed with each other. These shearing rollers ( 20, 20 ) are rotated in opposite directions in a state that the plate member ( 2 ) in pinched by and between peripheral surfaces of these shearing rollers ( 20,20 ). These shearing rollers ( 20, 20 ) are provided with at least one pair of shearing portions ( 21, 21 ) to be engaged with each other to shear the plate member ( 2 ). These shearing portions ( 21, 21 ) are formed on the peripheral surfaces and extend in an axial direction of the roller ( 20, 20 ).</p> |
