Abstract: There is disclosed a roller interchange device 200 comprising: a support 202 for mounting on a composite material lay-up head 100; a plurality of roller mounts 208 for mounting respective rollers 312, 314. Each roller mount 208 is selectively moveable to a respective engaged position relative the support 202. The engaged position of each roller mount 208 corresponds to a respective roller being held at a compaction location relative the head when the support is mounted on the head.

Abstract: A gantry system supports a human user in a harness attached to a carriage on a track. The carriage may comprise a body defining a U-shaped or C-shaped opening sized to receive a cylindrical track, and a pair of wheels attached to the body that roll along a top portion of the track with sufficiently minimal drag to permit the user to move the carriage without assistance. Single track embodiments may have a straight or curved trajectory and may have intersecting track portions with junctions that move between the intersecting track portions. In other embodiments, the carriage traverses a perpendicular track spanning a pair of parallel tracks. The perpendicular track may traverse the parallel tracks with or without motorized assistance. A counterweight system may provide partial weight support for the user. In one embodiment, the tracks are supported by a collapsible free-standing structure.

Abstract: An apparatus for splicing an elongate multi-layered workpiece includes: (a) drives and guides cooperating to drive the workpiece along a working path; (b) a cutter for severing the workpiece; (c) a layer manipulator for separating layers; (d) an applicator for applying adhesive; and (e) a deflector unit for deflecting the workpiece from the working path. The cutter effects the severing to present first and second workpiece segments. The layer manipulator effects inter-layer separation in one segment to present an interlayer zone in the one segment. A drive inserts the other segment in the interlayer zone. The layer manipulator urges the layers together to capture the other segment within the interlayer zone to establish a multi-layer structure. A drive and at least one of the workpiece deflector unit and the applicator situate the multi-layer structure adjacent to the applicator for finishing the splicing by applying adhesive to the multi-layer structure.

Abstract: A tape placement head for applying thermoplastic tape to an object includes a heated feeder which guides the tape/tow to a heated zone. The heated zone has a line compactor having a single row of at least one movable heated member. An area compactor is located in the heated zone downstream from the line compactor. The area compactor includes a plurality of rows of movable feet which are extendable toward the tape/tow different distances with respect to each other to conform to the shape of the object. A shim is located between the heated compactors and the tape/tow. A chilled compactor is in a chilled zone downstream from the heated zone. The chilled zone includes a line chilled compactor and an area chilled compactor. A chilled shim is mounted between the chilled compactor and the tape/tow.
