Title (EN) FIBER PLACEMENT HEAD WITH SECONDARY COMPACTION ARRANGEMENT
(FR) TÊTE DE PLACEMENT DE FIBRES POURVUE D'UN AGENCEMENT DE COMPACTAGE SECONDAIRE
Abstract: front page image
(EN)A fiber placement head with secondary compaction arrangement is provided. The fiber placement head includes a frame, at least one heating module mounted to the frame, and a primary compaction roller mounted to the frame. The secondary compaction arrangement includes a secondary idle compacting roller, operating after the primary compacting roller, performing a post retracing on the tows just applied by the primary compaction roller. The secondary compaction arrangement may also include an additional (secondary) heating module interposed between the primary and secondary compaction rollers. Re-heating and re-pressing the tows addresses those tows which are insufficiently bonded to a working surface due to the tow being insufficiently tacky.
(FR)La présente invention concerne une tête de placement de fibres pourvue d'un agencement de compactage secondaire. La tête de placement de fibres comprend un cadre, au moins un module de chauffage monté sur le cadre, et un rouleau de compactage principal monté sur le cadre. L'agencement de compactage secondaire comprend un rouleau de compactage au ralenti secondaire, actionné après le rouleau de compactage principal, réalisant un post-retrait sur les câbles venant d'être appliqués par le rouleau de compactage principal. L'agencement de compactage secondaire peut également comprendre un module de chauffage (secondaire) supplémentaire intercalé entre les rouleaux de compactage principal et secondaire. Le réchauffage et la remise en pression des câbles concernent les câbles qui sont insuffisamment liés à une surface de travail du fait que lesdits câbles sont insuffisamment collants.
