    DETAILED DESCRIPTION
    Although the braiding machine 10 of FIG. 1 has been described in the foregoing, it will be described in more detail in the following.
    The machine 10 comprises a table whose upper plate forms the plate 12 above. The plate 12 is substantially horizontal in the example shown. It carries a central chimney 40 of vertical axis A and around which extends the row of members 14. The chimney 40 extends upwards from the plate 12 and carries at its upper end a first ring 42 of axis A of revolution.
    A second ring 44 of axis A of revolution is disposed above the first ring 42 and at a distance therefrom to allow the passage of wires between the rings 42, 44. The second ring 44 is connected by bars 46 substantially horizontal to the upper ends of vertical rods 48 whose lower ends are fixed on the plate 12. The rods 48, here three in number, are regularly distributed around the axis A.
    The wheel 22 of each member 14 is located above the plate 12 and its pinion 18 is located below the plate 12. The pinions 18 of the members 14 are meshed with each other and with an output pinion of a motor 50, here associated with a gearbox 52. The motor 50 drives a first member 14 in rotation in the clockwise direction (or anti-clockwise) which will cause the driving of the adjacent members in the opposite direction. Thus, as is schematically represented by the arrows in FIG. 4, one half of the members 14 rotate in the clockwise direction and the other half of the members rotate counterclockwise.
    The guide means of the spindles 16 comprise an annular row of sectors 54 fixed on the plate 12 and each defining the sliding path 32 of the member 14 corresponding. Each sector 54 is here formed by a metal block in which the path 32 is formed by machining. The sectors 54 are arranged circumferentially end-to-end next to each other around the axis A, and comprise at their circumferential ends receiving means 56 for receiving switching means 36.
    In the example shown in FIGS. 4 and 5, these switching means are discs 36. At each circumferential end of a sector 54, the sliding path is interrupted by the housing 56. intersecting X-path portions which connect the circumferential ends of the path of one sector to the circumferential ends of the adjacent sector path (Figures 4 and 5).
    Each spindle 16 comprises a lower base 26 and an upper spool of threads 60. FIGS. 6 and 7 show a base 26 which notably comprises two superimposed plates 30, respectively lower and upper. The plates 30 have a peripheral contour of elliptical or oblong shape. They are spaced from one another and connected together by substantially vertical rods 62 visible in FIG. 2. The inter-plate space is configured to receive a peripheral portion of the wheel 20 of an organ 14, the rods 62 being intended to be engaged in the notches 22 of the wheel 20. The cooperation of the rods 62 with the notches 22 and the rotational drive of the members 14 will result in a rotation of the spindles 16.
    The upper plate 30 carries means 64 for fixing the coil 60. The lower plate 30 comprises cylindrical housings 66 for receiving and guiding in rotation about parallel vertical axes C of the guide elements 34. Each guide element 34 comprises an upper cylindrical member 68 engaged with small gaps in the corresponding housing 66, and a lower ogive 70 intended to be engaged in the sliding paths 32 and the switch discs 36 and to cooperate with them to guide the spindles 16 in rotation around axes A and B.
    Each warhead 70 has an elongated shape and comprises a central body having two parallel side surfaces 70a, and front and rear ends pointed. Each of these ends comprises two inclined lateral surfaces 70b. Finally, each nose 70 comprises a lower surface 70c substantially perpendicular to the axis C.
    The machine 10 further comprises means for driving or winding a cable for braiding or overbraiding. These means are carried by the plate 12 and comprise a vertical arm 72 (Figure 1) carrying a drive wheel 74 about a horizontal axis D of a cable (not shown) intended to pass inside the chimney 40 and a guide strapping 76 disposed above the two rings 42, 44. A roll of cable not yet braided may be located under the tray 12, in storage means 78.
    The braiding machine 10 operates as follows. The cable to be surrounded by a braid is moved from bottom to top through the chimney 40 and the strapping 76, driven by the wheel 74. The spindles 16 are mounted on the wheels 20, the rods 70 of the bases 26 of the The spindles 16 being engaged in the notches 22 of the wheels 20 of the members 14. The spindle threads 16 pass between the rings 42, 44 and are intertwined on the cable as it moves upwards. For this, each spindle 16 is rotated about the axis B by a member 14, by cooperation with the corresponding sliding path 32, and is then transferred to another member to rotate about the axis B of this other member , by cooperation on the one hand with the path portion of the disc 36 located between the members and on the other hand by the sliding path of this other member. Part of the spindles 16 rotate clockwise about the axis A and the other part of the spindles turn counterclockwise around the axis A.
    As explained above, the cleaning of the sliding paths 32 is long and tedious because it is done manually by means of a cotton fabric 80 and a metal spatula 82 which is used to move the fabric 80 in the path each sector and from one path to another (Figure 8).
    The present invention provides a simple, effective and economical solution to this problem with a cleaning tool 84.
    Figures 9 and 10 show an embodiment of the cleaning tool 84 according to the invention. This tool 84 comprises a base 86 similar to the base 26 of a spindle 16, so that the tool can cooperate with the bodies and be driven by them as explained in the foregoing.
    The base 86 comprises two superimposed plates 88, lower and upper respectively. The plates 88 have a peripheral contour of elliptical or oblong shape. They are spaced from each other and connected together by rods 90 substantially vertical. The inter-plate space is configured to receive a peripheral portion of the wheel 20 of a member 14, the rods 90 being intended to be engaged in the notches 22 of the wheel 20. The cooperation of the rods 90 with the notches 22 and the rotational drive of the members 14 will result in a rotational drive of the tool 84.
    The upper plate 88 may carry means 92 for gripping the tool. As for the base 26, the bottom plate 88 comprises cylindrical housings 94 for receiving and guiding in rotation about parallel vertical axes C of the guide elements 96. Each guide element 96 comprises an upper cylindrical member 98 engaged with weak games in the corresponding housing 94, and a lower ogive 1 DO, 100 'intended to be engaged in the sliding paths 32 and the switching discs 36 and to cooperate with them to guide the spindles 16 in rotation about the axes A and B. The rear warhead 100 has an elongated shape and comprises a central body having two parallel side surfaces 100a, and front and rear ends pointed. Each of these ends comprises two inclined lateral surfaces 100b. Finally, the warhead 100 comprises a lower surface 100c substantially perpendicular to the axis C. The front warhead 100 'has an elongated shape and comprises a central body having two parallel lateral surfaces 100a, and a pointed rear end which comprises two lateral surfaces 100b inclined. The warhead 100 'further comprises a lower surface 100c substantially perpendicular to the axis C. The warhead 100' being configured to drive or to be equipped with a cleaning means, such as a piece or fabric of cotton, sliding tracks 32. In the example shown, the front end of the front warhead 100 'comprises a truncation which defines a surface 100d inclined relative to the surface 100c and substantially perpendicular to a longitudinal plane P of the ogive 100 'passing through its axis C. Moreover, the ogive 100' is shortened and therefore shorter than the warhead 100, its front end having a rounded front edge substantially around said axis C.
    The surface 100d is a bearing and driving surface of the piece of cotton 80, which is therefore intended to be moved in the sliding paths 32 for cleaning as the tool is moved by the members 14.
    The cleaning of the sliding paths 32 of the braiding machine 10 can be carried out as follows. At least one tool 84 is mounted on a member 14, the rods 90 of its base 86 being engaged in the notches 22 of the wheel 20 of this member 14. The warheads 100, 100 'of the base are engaged in the sliding path 32 corresponding and a piece of cotton 80 is disposed in front of the front warhead, and wedged between the bottom of the sliding path and the surface 100d of the warhead 100 '. The tool 84 is rotated about the axis B by the member 14, by cooperation with the corresponding sliding path 32, then is transferred to another member to rotate about the axis B of the other member, by cooperation on the one hand with the path portion of the disk 36 located between the members and on the other hand by the sliding path of this other member. The tool 84 rotates clockwise (or counterclockwise, respectively) about the axis A, which makes it possible to clean half of the sliding paths 32. The tool is removed from the member and mounted on a directly adjacent member and the aforementioned steps are repeated so that the tool 84 rotates counterclockwise (or clockwise, respectively) about the axis A, which allows to clean the other half of the paths of slip 32.
