Abstract
The system for stretch-forming composite material bands (3) includes, in addition to an unrolling head (20), an original assembly composed of a light source (4) for heating the band (3) and hardening the composite and a pair of rollers (6a and 6b) applying the desired pressure to assemble the band to a laminated composite (2) already deposited or applying it to the support (1). As the application of heat is concentrated at a distance from the rollers (6a and 6b) and with a perpendicular incidence, the rollers can be conveniently made of an elastic material, which enables them to adapt to the transverse curvature of the support equipment (1) and to apply a uniform pressure.
