1. A tooling for winding a fibrous fabric, comprising:
at least one support on which the fibrous fabric is intended to be wound about a first winding axis, the at least one support having at least two end regions spaced apart along a second axis transverse to the first axis,
a motion device configured to modify a shape of the at least one support between a retracted configuration and extended configuration by gradually drawing closer or drawing apart the end regions along the second axis said support having an elongated shape along the second axis, and
a first compaction device configured to perform compaction on the end regions at least in the retracted configuration and a second compaction device, differing from the first compaction device, configured to perform compaction on a central region lying between the end regions in the extended configuration, and wherein each end region comprises a distal end and two side portions positioned either side of the distal end and located on the side of the central region, and wherein the first compaction device comprises a first compacting element having a first compacting surface configured to perform compaction on the distal end of each end region and a second compacting element having a second compacting surface configured to perform compaction on the side portions of each end region with a compacting component directed towards the central region wherein the second compacting element has at least one lateral surface forming a non-zero angle with the normal to the support at this surface, said non-zero angle being at a joint between the first and second compacting surfaces.
