| 摘要 |
The present invention is an apparatus for inserting yarns into a reinforcement material along their longitudinal path. The apparatus for moving yarn and for constraining yarn movement, such as yarn brakes, are each actuated at the appropriate time. The yarn is prevented from buckling by a hollow member of a diameter 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 case is taken to include any textile yarn, monofilament, coated yarns, and the like.
