Abstract

Method for cleaning a braiding machine, particularly a machine for braiding electrical cables, said braiding machine comprising a plateau (12) for supporting an annular row of spindle drive members (14), characterized in that it comprises a step of equipping the machine with at least one cleaning tool (84), this cleaning tool comprising on the one hand means (90) configured to be driven by the members and, on the other hand, at least one guide element configured to be housed in slideways (32) for the movement of the tool, said guide element being configured to drive or to be equipped with a means (80) of cleaning said slideways, and a step of rotating said members so as to drive said cleaning means in said slideways.

First claim

The invention claimed is:

1. A method for cleaning a braiding machine having a platform for supporting an annular row of members for driving bobbins, said members extending around a first common axis and being rotatably movable about a plurality of second axes which are substantially parallel to one another and to said first common axis, said members each comprising a pinion meshed with pinions of adjacent members and a wheel which comprises notches over its circumference configured to receive complementary portions of the bobbins so as to drive said bobbins about said plurality of second axes, said platform comprising, for each member, an annular sliding track which extends around one of the plurality of second axes of the corresponding member and is configured to receive an element for guiding each bobbin so as to guide said bobbin about said one of the plurality of second axes, each sliding track being connected to adjacent sliding tracks by a switch so as to rotate the bobbins about said first common axis by moving the bobbins from one member to the next adjacent member in each instance,
said method comprising:
providing a cleaning tool with the machine, said cleaning tool including first portions to be received in at least some of the notches in each wheel so as to drive said cleaning tool about said plurality of second axes, said cleaning tool comprising one or more bearing surfaces of a first guide to be received in said sliding tracks so as to move said cleaning tool about said first common axis, at least one bearing surface of said one or more bearing surfaces of the first guide being configured to drive a piece of cotton or cleaning cloth to clean said sliding tracks or to be provided with said piece of cotton or cleaning cloth; and
rotating said members to drive said cleaning tool about said first common axis and said plurality of second axes.

2. The method of claim 1 , wherein said first portions of said cleaning tool include rods.

3. The method of claim 1 , further comprising:
mounting the cleaning tool on a first of said wheels,
rotating said members in order to drive said cleaning tool about said first common axis and said plurality of second axes, thereafter
mounting the cleaning tool on a second wheel that is adjacent to said first wheel,
rotating said members in order to drive said cleaning tool about said first common axis and said plurality of second axes.

4. The method of claim 1 , wherein said cleaning tool comprises a second guide having one or more bearing surfaces.

5. The method of claim 4 , wherein said cleaning tool said first and second guides are mounted such that the first and second guides are free to rotate about substantially parallel axes.

6. The method of claim 4 , wherein said first guide comprises a truncation for accommodating and driving said piece of cotton or cleaning cloth.

7. The method of claim 6 , wherein said truncation is defined by said at least one bearing surface that is substantially perpendicular to a plane that passes through the axis of rotation of the first guide.

8. The method of claim 4 , wherein each of said first and second guides is generally in the shape of an ogive.

9. A cleaning tool, comprising:
a tool body having a base with base portions receivable in at least some of a plurality of notches in a wheel so as to drive said cleaning tool about a plurality of axes, said base having a guide with one or more bearing surfaces to be received in sliding tracks so as to move said cleaning tool about a first common axis, said one or more bearing surfaces of the guide being configured to drive a piece of cotton or cleaning cloth to clean said sliding tracks or to be provided with said piece of cotton or cleaning cloth.

10. A braiding machine provided with a cleaning tool according to claim 9 .
