Machine for applying fibers, including a flexible compacting roller with a heat adjustment system

摘要

The present invention relates to a machine for applying fibers for making composite material, including a compacting roller (2) for applying a strip consisting of at least one planar fiber preimpregnated with resin on an application surface, and a heating system capable of emitting a thermal radiation toward said strip. The compacting roller comprises a rigid central tube (4) provided with radial holes (41) and a cylinder (3) made of a flexible material, elastically deformable, arranged on said central tube, and having fluid communication means (32, 34, 35) for placing said radial holes in fluid communication with the outer surface (33) of said roller. Said machine comprises heat adjustment means capable of injecting a heat adjustment fluid into the inner passage (42) of the central tube.
