ABSTRACT:
A guide device for rotatably supporting and for guiding a bar to a spindle of a machine tool; the device comprises: a first and a second set of opposed jaws to receive and rotatably support a bar to be fed to the spindle of the machine; one set of jaws is rotatably journalled by support members to rotate between a closed and an open condition of the guide. Axially spaced apart support members are provided for removable journalling the first and the second set of jaws, and a square rod system longitudinally extending between adjacent support members to slidably engage each set of jaws, preventing rotation of the same jaws in respect to the support square rods. Removable shaft members are provided in the square rod system for rotatably journalling the supporting rods for movable jaws, and elastically biasing elements to rotate the square rods and the set of movable jaws towards the fixed set of jaws of the guide device.
