STRAND LAYING APPARATUS AND MACHINE

摘要

A strand laying head is disclosed wherein strands of composite material pass from a strand storage device under a spacing roller and are warmed by a heat source. A precompaction roller applies pressure to the strands against a laydown surface as the head moves along the laydown path. A trailing main compacting roller applies final compacting pressure. A heat source is applied to the strand at a point between the precompaction and main compacting rollers to ensure final bonding of the strands.
