发明名称 COVERING FOR A SEED OR PLANT BED
摘要 A light weight, substantially rectangular covering for a seed or plant bed comprising: a flat, substantially planar body portion formed of a nonwoven reticulated filamentary structure of overlapping, intersecting continuous synthetic organic thermoplastic filaments bonded to each other at a multiplicity of irregularly spaced points along their lengths, the continuous filaments being disposed in random, intermingled configurations uniformly distributed throughout the structure without a pattern of parallelism between the continous filaments so that no two parts of the structure are identical reinforcing edge portions on both sides and both ends of the seed or plant bed covering; reinforcing strips of synthetic organic thermoplastic material positioned within the reinforcing edge portions of the nonwoven reticulated filamentary structure; and a plurality of openings formed at spaced intervals in the reinforcing edge portions and the reinforcing strips for use with fastening devices whereby the covering may be secured in place over the seed or plant bed during use.
