Abstract
Abstract A lawn nursery strip is provided by apparatus employing regenerated cotton to form a strip with a raised nap on a front side. The rear of the strip is sequentially fertilized, bonded, and strengthened; then the napped front of the strip is sequentially seeded, fertilized, bonded, and covered. The strip is rolled compactly by the apparatus described for transport or storage until needed for use. This is a continuation, of application Ser. No. 520,985, filed Nov. 5, 1974, now abandoned.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
181 words
The method of making a nursery seeding strip which includes the sequential steps of, feeding and carding regenerated cotton fibers at a constant rate to form a strip of processed cotton material which is napped and waffled on one side, successively spreading first liquid fertilizer and then liquid binder in the form of a spray to coat the opposite side of the strip with fertilizer and liquid binder, thereafter drying the coated strip to produce a dried nursery cotton strip, simultaneously leaching localized bands of synthetic liquid resins continuously onto the coated side of the nursery cotton strip to form longitudinal streaks on the nursery strip for increasing the tensile strength thereof in a longitudinal direction, sowing seeds onto the opposite side of the nursery cotton strip, vibrating the strip so that the sown seeds will settle stably into the napped surface of the strip, successively spreading first liquid fertilizer and then liquid binder in the form of a spray over the napped, seeded surface, and press bonding a non-woven, net-like material onto the surface to form the completed seeding strip.
