Abstract
A facility for manufacturing at least first and second assemblies of M1 filamentary elements and M2 filamentary elements, in which each of the first and second assemblies includes a plurality of filamentary elements wound together in a helix, includes an assembling apparatus and a splitting apparatus. The assembling apparatus of the facility assembles M filamentary elements together into a layer of M filamentary elements around a temporary core, to form a temporary assembly. The splitting apparatus of the facility splits the temporary assembly into at least the first and second assemblies of M1 filamentary elements and M2 filamentary elements.
Claims12
1-11. (canceled)
12:
- A facility for manufacturing at least first and second assemblies of M1 filamentary elements and M2 filamentary elements, each of the first and second assemblies including a plurality of filamentary elements wound together in a helix, the facility comprising:
- an assembling apparatus structured to assemble M filamentary elements together into a layer of M filamentary elements around a temporary core, to form a temporary assembly;
- and
- a splitting apparatus structured to split the temporary assembly into at least the first and second assemblies of M1 filamentary elements and M2 filamentary elements.
13:
- The facility according to claim 12, wherein the splitting apparatus includes a separator structured to separate the temporary core from the first and second assemblies.
14:
- The facility according to claim 12, further comprising:
- a first separator structured to separate the first assembly from a temporary collection formed of the second assembly and the temporary core;
- and
- a second separator structured to separate the second assembly and the temporary core from each other, the second separator being located downstream of the first separator.
15:
- The facility according to claim 12, further comprising a guide apparatus structured to guide the temporary core between an outlet of the splitting apparatus and an inlet of the assembling apparatus.
16:
- The facility according to claim 12, further comprising a core splitter structured to split the temporary core between at least the first and second assemblies.
17:
- The facility according to claim 16, wherein the core splitter includes a first separation section structured to separate at least a first part of the temporary core with first filamentary elements from the temporary assembly so as to form the first assembly.
18:
- The facility according to claim 16, wherein the core splitter includes a second separation section structured to separate at least a second part of the temporary core with second filamentary elements from the temporary assembly so as to form the second assembly.
19:
- The facility according to claim 12, wherein the assembling apparatus includes a twister structured to twist the M filamentary elements and the temporary core.
20:
- The facility according to claim 12, further comprising a balancer apparatus structured to twist-balance the temporary assembly.
21:
- The facility according to claim 12, further comprising a rotation-maintenance apparatus structured to maintain a rotation of the first assembly and the second assembly about their respective directions of travel, the rotation-maintenance apparatus being arranged downstream of the splitting apparatus.
22:
- The facility according to claim 12, wherein, upstream of the assembling apparatus, the facility includes no preforming apparatus structured to preform each of the filamentary elements individually.
