A self-threading lamination head has a material supply drum, a backing layer collection drum, and a material threading system. The material supply drum supports a material roll of layup material backed by a backing layer. The material threading system includes at least one threading belt located on one side of the lamination head. The threading belt is supported by belt rollers driven by a belt drive motor. A belt-mounted layer engagement device is coupled to the threading belt for engaging a backing layer leading edge portion. The backing layer collection drum collects the backing layer as the lamination head applies the layup material onto a substrate. The belt drive motor drives the threading belt over the belt rollers and causes the belt-mounted layer engagement device to thread the backing layer through the lamination head, and position the backing layer leading edge portion proximate the backing layer collection drum.

Lamination head having self-threading capability

A lamination head for laying up a composite laminate includes a material supply drum supporting roll of layup material backed by a backing layer, a first and second separation device respectively having a first and second horn, and a first and second compaction device. When the first separation device is extended, the first horn is in close proximity to the first compaction device, causing a layup material to separate from the backing layer and move underneath the first compaction device as the lamination head moves along a first direction of travel. When the second separation device is extended, the second horn is in close proximity to the second compaction device, causing the layup material to separate from the backing layer and move underneath the second compaction device as the lamination head moves along a second direction of travel opposite the first direction of travel.
