ABSTRACT:
A bend portion of a bonded, laminated article is made substantially free of wrinkling, which results in interlaminar voids and discontinuities, by applying tension to at least one layer of a radially outer portion of a preform of the article during bonding, the tension being applied in a direction away from the bend, typically generally tangentially in respect to an inner portion. The apparatus includes a rigid support to carry the preform bend portion, held to the support to enable application of force or pressure to the outer layer.
