<p>A numerically controlled device such as a numerically slitter device has a plurality of units. Intervals between the units are numerically controlled to desired valves by moving the units. The numerically controlled device comprises an endless belt provided through the respective units, driving means for driving the endless belt under a numeral control to move the respective units, and clutch means provided at the respective units. The clutch means includes a forward path clamper for selectively clamping the forward path of the endless belt and a backward path clamper for selectively clamping the backward path of the endless belt. <IMAGE></p> |
