<p>The sliding table (4) comprises a carriage (9) placed under the said table and equipped with a pair of pulleys (10, 11) over each of which there is a belt (12, 13) having one end fixed to a machine bed (2) and the other end fixed to the sliding table (4); the carriage (9) is in turn associated to a movable element (14) of a two-directional, linear actuator (15) attached to the bed (2) which drives the sliding table (4) in both directions so that the latter moves by a quantity (S) that is double the equivalent quantity (S1) by which the carriage (9) on the linear actuator (15) moves. <IMAGE></p> |
