Abstract: An assembly including a carriage for driving a marking apparatus on at least one guide member wherein the carriage is secured to a bearing allowing the carriage to slide on the guide member. The carriage includes at least one opening made with transverse dimensions substantially greater than those of the guide member so that when the carriage is placed in position, an intermediate space is defined between the walls of the opening and an opposite outer periphery of the guide member which space is filled with a polymerizable resin which forms a bearing sleeve between the walls of the opening and at least a part of the outer periphery of the guide member.

Abstract: A marking machine including a frame, an arm articulated on the frame about an axis of articulation, and a marking tool movably mounted on the arm, The marking tool is movable in translation with respect to the arm.

Abstract: A device including a receiving device for a stack formed by sheets of stock material that move by gravity along the receiving device toward a marker and which includes positioning elements for positioning a sheet to be marked with respect to the marker, and which also includes an ejector for the marked sheets. The marker is arranged under the receiving device and it is used to mark the underside of each bottom sheet of the stack.

Abstract: Disclosed is a marking device, wherein the two telescopic jacks which control orientation of the tool-holder rod are coupled to the wall of the fixed casing with the aid of ball-and-socket joints disposed along the plane transverse to the rod which passes through the centre of the articulated linkage supporting the rod.

Abstract: A device for marking objects by micro-percussion pneumatic tools including a vibrating tip wherein the tools are mounted on a carriage which is slidably mounted with respect to two support shafts and which is moved along an axis of translation by a first drive member and wherein the carriage is pivotally mounted to swing the tip of the tool in a direction perpendicular to the direction of translation by a second drive member.

Abstract: A device and process for adjusting the position of a tool-holder head along an axis with the tool-head moving along a guiding element and with a pulley mounted to rotate freely on a shaft secured to the tool-holder head and which is moveable along a taut cable. A maneuvering handle is provided and may be in mesh with the pulley in order to drive it or may be moved away therefrom so as to be free to rotate on the shaft.
