Abstract
A motorized head for applying fiber composite material to an application surface includes a drive roll and a backup roll for feeding fiber composite material toward the application surface, a compaction roll for pressing fiber composite material onto the application surface, and a restart pinch roll assembly located between the drive roll and the compaction roll for driving fiber composite material received from the drive roll to the compaction roll. The drive roll nip between the drive roll and the backup roll forms a drive zone that grips and drives the composite material, a clamp zone that prevents movement of the composite material after it has been cut, and a free zone that allows composite material to be freely pulled through the head. Two cutters mounted on the drive roll mesh with a single anvil on the backup roll to cut the composite material to the desired length.
