Abstract
A multiplicity of pile-like engaging elements are fused integrally with top faces of each of elevated portions formed on a first surface of a flat plate-like substrate comprised of the first surface and a second surface such that more than ¼ of cross sectional areas of the entangled yarn are buried therein. The entangled yarns are fused integrally with the elevated portions firmly due to existence of the elevated portions regardless of a certain thickness of the flat plate-like substrate. In the meantime, it is permissible to form covering portions for covering the entangled yarn locally with component material of the flat plate-like substrate instead of the elevated portions. As a result, the female engaging member can be produced continuously without increase of equipment cost and the like. Further, a sufficient fixing strength can be provided to pile yarn rows bonded and fixed to the substrate surface although the pile yarns are fixed by fusion of the flat plate-like substrate. Therefore, a high productivity can be secured. A production apparatus is also provided for realizing such a female engaging member.
