METHOD AND APPARATUS FOR PRODUCING SOLID PROFILES FROM A STRIP OF RESIN-PREIMPREGNATED FIBRE

摘要

The method comprises the steps of: providing a planar strip (10) of fibre preimpregnated with resin, which has a longitudinal direction and a transverse direction; corrugating the planar strip (10) to form a corrugated strip (11) with a plurality of zigzag folds parallel to said longitudinal direction; and compacting said corrugated strip (11) in said transverse direction in order to place in contact and to join, one to the other, surfaces of said plurality of folds in order to form a solid profile (12). The apparatus includes: a corrugating unit with a pair of corrugating rollers provided with matching circular striations suitable for corrugating said planar strip (10); and a compacting unit that comprises at least one pair of facing, lateral rollers suitable for compacting said corrugated strip (11) laterally until said solid profile (12) is obtained.
