Fiber application machine comprising a flexible compacting roller with a thermal regulation system
First Claim
1. A fiber application machine for the production of parts made of composite materials comprising a compacting roller for applying, on an application surface, a band formed of at least one resin pre-impregnated flat fiber, and a heating system adapted to emit heat radiation directed towards the band, said compacting roller comprising a rigid central tube, and a cylinder made of an elastically deformable, flexible material, assembled on said central tube,said central tube being provided with radial holes, said flexible material cylinder having fluid communication means adapted to bring said radial holes into fluid communication with the external surface of said cylinder, said machine comprising thermal regulation means able to inject a thermal regulation fluid in the internal passage of the central tube.

Abstract
A fiber application machine for the production of parts made of composite materials comprising a compacting roller for applying on an application surface a band formed of at least a resin pre-impregnated flat fiber, and a heating system able to emit a heat radiation towards the band. The compacting roller comprises a rigid central tube provided with radial holes, and a cylinder made of an elastically deformable, flexible material, assembled on the central tube, and having a fluid communication assembly that brings the radial holes into fluid communication with the external surface of the cylinder. The machine includes a thermal regulation system that injects a thermal regulation fluid in the central tube internal passage.
