Claims
- 1. A machine for the construction of a braid (11) including a set of identical multiindented wheels (2), which are mounted on a fixed support (1) and driven in rotation to cause the circulation of spindles (6) carrying spools (7) of braiding elements (8), said multiindented wheels being disposed in parallel and equidistant lines (L—L), wherein:in said set of multiindented wheels: the multiindented wheels (2) belonging to a line are spaced from one another, so that two consecutive multiindented wheels belonging to one and the same line cannot cooperate directly with one another; a multiindented wheel (2) belonging to one line is disposed between two multiindented wheels belonging to an adjacent line and cooperates with said two multiindented wheels; and in the spaces between the consecutive multiindented wheels of a line, there are provided passages (3) for longitudinal elongate elements (9) of said braided tubular structure.
- 2. The machine as claimed in claim 1, wherein within said spaces between the consecutive multiindented wheels of a line there are further provided rhomboidal needles (17) of controlled orientation which are intended either to cause said spindles (6) to pass from one multiindented wheel to another belonging to an adjacent line, or to maintain said spindles on their respective multiindented wheels.
- 3. The machine as claimed in claim 2, wherein said needles (17) are coaxial with said passages (3) for the elongate elements (9).
- 4. The machine as claimed in claim 2, wherein said needles (17) are controlled in orientation by a linkage gear (19, 20).
- 5. A machine as claimed in claim 2, wherein, at any given moment:all the needles (17) associated with a line of multiindented wheels (2) are parallel to one another and thus have a common orientation; and the common orientations of the needles (17) associated with two adjacent lines of multiindented wheels (2) are symmetrical with respect to one another in relation to said lines.
- 6. The machine as claimed in claim 1, wherein said fixed support (1) of the multiindented wheels is planer.
- 7. The machine as claimed in claim 1, wherein said fixed support (31, 41) of the multiindented wheels (2) is cylindrical.
- 8. The machine as claimed in claim 7, wherein the axis (H—H) of said fixed cylindrical support (31) is horizontal.
- 9. The machine as claimed in claim 7, wherein the axis (V—V) of said fixed cylindrical support (41) is vertical.
- 10. The machine as claimed in claim 1, which includes cutting means (33) for longitudinally splitting said braid (11).
