A workpiece M is fed to the cutting zone of the machine, eg. a bandsaw, by a movable vice 27 having jaws interconnected by a carriage 29 extending below rollers 21 which support the workpiece. Movement of the jaws 31 and 33 is effected hydraulically when fluid is fed to chambers 79a, 79b, on each side of a piston 95 and a chamber 129a, on one side of a piston 135 against the action of a spring 141. <IMAGE> |
