Abstract
Upper and lower rotating drums ( ) having shearing blades ( ) are supported by a bearing frame ( ) via eccentric sleeves ( ). Only the upper rotating drum ( ) is rotated by a drive motor 17, while the eccentric sleeves ( ) are rotated by a drive motor so that the rotating drums ( ) can be made to approach and separate from each other. Interlocking gears ( ) are fixed to shaft end portions of the rotating drums ( ) to permit interlocking of the rotating drums ( ) when these drums approach. Oldham's couplings ( ) are interposed between the interlocking gears ( ) and timing gears ( ) to rotate the rotating drums ( ) constantly and synchronously.
