<p>The first slitting disc (5) is mounted on a hub (1). The hub has a large dia. flange (1') against which the slitting disc is clamped by a ring nut with flange (1"). The second slitting disc (11) is mounted on a sleeve (9) of large dia. The disc is clamped against the flange by a second ring nut with flange (9"). The sleeve on which the second disc is mounted fits on the hub of the first disc, and is located axially by a pin (23) which passes through hub and sleeve. The pin is pulled by a nut (29) and screw (19) arrangement against a ring nut (15) mounted on the hub. The second disc is therefore securely positioned in relation to the first one.</p> |
