  • Patent number: 9162434
    Abstract: A system and method for making advanced composite laminates includes a tape dispensing system, a tape placement head, and a tooling surface. Tape sections are formed and moved through a tape section guide using a gripping assembly. The tape section guide system is suspended over the tooling surface. Once the tape section is positioned over a desired location on the tooling surface, a tape tacking device tacks or otherwise attaches the tape section to the tooling surface or another underlying tape section.

  • Patent number: 8992715
    Abstract: An embodiment of the present invention provides a method for manufacturing a composite preform from tape material, including feeding a tape section into a tape section guide that suspends the tape across a tooling surface, moving at least one of the tape section guide and the tooling surface relative to each other to position the tape section at a desired location and orientation relative to the tooling surface, moving the tape section toward a pre-existing tape section disposed on the tooling surface, and tacking the tape section to the pre-existing tape section. A corresponding apparatus for manufacturing composite preforms is also disclosed.

  • Patent number: 7353853
    Abstract: A fiber placement machine has a creel that supplies a fiber band to a presser member that applies the fiber band to a tool or form. The presser member is part of a head that is attached to the creel of the machine by a wrist that provides movement about yaw, pitch and roll axes with respect to the creel. The fiber band is supplied by a fiber band delivery system that is associated with the wrist and that is characterized by a capability to twist the fiber band in two stages about the yaw axis or the roll axis.
