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.
Process for assembling a carriage driving a marking apparatus on at least one guide member, said carriage being secured to a bearing including a ring allowing the carriage to slide on said at least one guide member, the process including making at least one opening in said carriage adapted to receive said bearing such that said bearing is interposed between a wall defining the opening and said at least one guide member, forming said bearing by placing an intermediate ring around said at least one guide member, the opening having a transverse dimension substantially greater than a transverse dimension of said intermediate ring, placing said carriage in a position such that an intermediate space is defined between said wall of the opening and an opposite outer periphery of said ring, filling the intermediate space with a polymerizable resin and, polymerizing the resin to form said bearing to include a sleeve between said wall of the opening and at least a portion of the opposite outer periphery of said intermediate ring.

1. Field of the Invention
The present invention relates to a process for assembling a carriage for driving a marking apparatus on at least one guiding member, as well as to a corresponding marking apparatus.
Within the meaning of the invention, the generic term “marking apparatus” designates any apparatus for making a mark on the surface of a piece, whether it be by printing, deformation or by removal of matter on or from this surface.
The invention will be described hereinbelow with reference to the accompanying drawings, given solely by way of non-limiting example and in which:
FIG. 1 is a view in perspective of a marking apparatus according to the invention.
FIGS. 2 and 3 are schematic views in section, illustrating two steps of the assembly, on a guide member, of a carriage belonging to the marking apparatus of FIG. 1; and
Referring now to the drawings, the marking apparatus shown in FIG. 1 and generally designated by reference 2, comprises, in manner known per se, a fixed frame 4 comprising two opposite raised edges 6. The latter support two bars 8 which constitute guide members for the displacement of a first carriage 10 along the principal axis of these bars.
This first drive carriage 10 is provided with two opposite raised edges 11 between which extend two additional guide bars 12, the two pairs of bars 8, 12 being disposed substantially at right angles.
The bars 12 ensure guiding of a second carriage 14, on which is connected a marking tool 15, which may for example be a pneumatic stylus, or an engraving head. These two carriages 10, 14 form a mechanism for driving the marking apparatus 2, and ensure positioning of the marking tool in two directions orthogonal with respect to each other. The two carriages 10, 14 are respectively set in motion, in manner known per se, via electric motors (not shown).
