| Title | Tow placement apparatus and method |
| Description | A tow placement head for forming a variable angle tow composite structure comprises a pinch arrangement 8,102 to receive a tow tape and pass it to a compaction shoe 9 to press it against a surface on which the tow tape is to be laid. Shear deformation is applied to a portion of the tow tape between the compaction shoe and the pinch arrangement. The pinch arrangement may be immovable relative to the compaction shoe, the compaction shoe allowing tow tape to slide over its surface which may comprise PEEK or high molecular weight polyethylene. Alternatively, this may be achieved by allowing movement between the pinch arrangement and the compaction shoe and or between the pinch arrangement and the tow material adhered to the surface. An abutment surface 91 of the compaction shoe 9 may have a fixed angular relationship to the pinch region or may be rotatable relative to the pinch region. The placement head may include a tow tape cutter, width regulator and/or a backing member collector. An endless backing member may be provided. The pinch arrangement may inhibit movement of tape across its width, and may comprise abutting shoes or an abutting shoe and roller. |
