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.
