The present invention is an apparatus (10) for inserting yarns (Y) into a reinforcement material along their longitudinal path. The apparatus includes devices for moving yarn and for constraining yarn movement, such as yarn brakes (48, 56), each actuated at the appropriate time, plus a device for preventing the yarn from buckling, such as a hollow member (20) of a diamete r only slightly greater than the yarn, when the yarn is pushed on. The reinforcement material may be woven or non-woven fabrics, cellular foams, or combinations that may include fabrics, foams or air gaps. "Yarn" in this cas e is taken to include any textile yarn, monofilament, coated yarns, and the li ke.
