Abstract
Abstract A fibrous web for planting seeds consists essentially of a mat of randomly oriented, unmodified, natural straw-like cellulosic fibers, viable seeds, water soluble adhesive and fertilizer on a tissue paper backing. A method of sowing an area of soil with seeds comprising laying the aforementioned web over the area. Apparatus for producing the aforementioned web comprises a conveyor belt, means for driving the conveyor belt, means for placing tissue paper backing on the conveyor belt, means for depositing onto the tissue paper backing on the conveyor belt while it is driven dry, fluffed randomly oriented, unmodified, natural cellulosic fibers to form a layer thereof on the conveyor belt, means for leveling the fluffed layer to form a mat, means for spraying an aqueous solution of water soluble adhesive onto the mat, means for depositing seed and fertilizer onto the wet adhesive bearing mat and means for drying the wet mat containing adhesive, seed and fertilizer.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
188 words
The method of forming a fluffy uncompressed rolled seeded or unseeded straw-like mulch mat capable of being unrolled, which derives its entire structural strength and unity from tissue paper backing on which randomly oriented, unmodified, natural, elongated, straw-like cellulosic fibers, bonded together through spot contact bonding between contiguous straws and between the tissue paper backing and the straws by a water soluble adhesive which due to the mat's density and thickness is spread substantially throughout, including the steps of, feeding onto tissue paper backing on a conveyor a mat of fluffy randomly oriented, unmodified, natural, elongated and dry straw-like cellulosic fibers, spraying water soluble adhesive onto said straw-like cellulosic fibers, spreading onto the adhesive a predetermined amount of granular material from the class comprising seed and fertilizer, drying the adhesive and thereby bonding the straw-like fibers together and to the tissue paper backing and securing the granular material to the straw-like fibers by the adhesive on the straw-like fibers providing spot contact bonding only between contiguous fibers and with the granular material, and rolling the mat into a roll for storage and unrolling at the location of use.
Claim 2
Independent Claim
188 words
The method of forming a fluffy uncompressed rolled seeded or unseeded straw-like mulch mat capable of being unrolled, which derives its entire structural strength and unity from tissue paper backing on which randomly oriented, unmodified, natural, elongated, straw-like cellulosic fibers, bonded together through spot contact bonding between contiguous straws and between the tissue paper backing and the straws by a water soluble adhesive which due to the mat's density and thickness is spread substantially throughout, including the steps of, feeding onto tissue paper backing on a conveyor a mat of fluffy randomly oriented, unmodified, natural, elongated and dry straw-like cellulosic fibers, spraying water soluble adhesive onto said straw-like cellulosic fibers, spreading onto the adhesive a predetermined amount of granular material from the class comprising seed and fertilizer, drying the adhesive and thereby bonding the straw-like fibers together and to the tissue paper backing and securing the granular material to the straw-like fibers by the adhesive on the straw-like fibers providing spot contact bonding only between contiguous fibers and with the granular material, and rolling the mat into a roll for storage and unrolling at the location of use.
Claim 3
Independent Claim
155 words
The method of forming a fluffy uncompressed seeded straw mulch mat which derives its entire structural strength and unity from tissue paper backing on which randomly oriented, unmodified, natural, elongated, straws, bonded together through spot contact bonding between contiguous straws and between the tissue paper backing and the straws by a water soluble adhesive which due to the mat's density and thickness is spread substantially throughout, including the steps of, feeding onto tissue paper backing on a conveyor a mat of fluffy randomly, oriented, unmodified, natural, elongated and dry straw, spraying water soluble adhesive onto said straws, spreading onto the adhesive a predetermined amount of granular seed and fertilizer, drying the adhesive and thereby bonding the straws together and to the tissue paper backing through spot contact bonding of contiguous straws, and securing the granular material to the straws by the adhesive on the straws making spot contact only with the granular seed and fertilizer.
Claim 4
Independent Claim
155 words
The method of forming a fluffy uncompressed seeded straw mulch mat which derives its entire structural strength and unity from tissue paper backing on which randomly oriented, unmodified, natural, elongated, straws, bonded together through spot contact bonding between contiguous straws and between the tissue paper backing and the straws by a water soluble adhesive which due to the mat's density and thickness is spread substantially throughout, including the steps of, feeding onto tissue paper backing on a conveyor a mat of fluffy randomly, oriented, unmodified, natural, elongated and dry straw, spraying water soluble adhesive onto said straws, spreading onto the adhesive a predetermined amount of granular seed and fertilizer, drying the adhesive and thereby bonding the straws together and to the tissue paper backing through spot contact bonding of contiguous straws, and securing the granular material to the straws by the adhesive on the straws making spot contact only with the granular seed and fertilizer.
Claim 5
Dependent Claim
96 words
A seeded and fertilized mulch mat having a thickness and density which derives its entire structural strength and unity from tissue paper backing on which randomly oriented, unmodified, natural, elongated, straws are secured and bonded together through spot contact bonding between contiguous straws and between the tissue paper backing and the straw by water soluble adhesive without the application of compression and including seed and fertilizer distributed uniformly over said straws opposite said tissue paper backing, and secured to said straws by said adhesive on said straws making spot contact only with said seed and fertilizer.
Claim 6
Dependent Claim
96 words
A seeded and fertilized mulch mat having a thickness and density which derives its entire structural strength and unity from tissue paper backing on which randomly oriented, unmodified, natural, elongated, straws are secured and bonded together through spot contact bonding between contiguous straws and between the tissue paper backing and the straw by water soluble adhesive without the application of compression and including seed and fertilizer distributed uniformly over said straws opposite said tissue paper backing, and secured to said straws by said adhesive on said straws making spot contact only with said seed and fertilizer.
Claim 7
Dependent Claim
14 words
The mat of claim 3 wherein the thickness is between 3/16 to 1/4 inches.
Claim 8
Dependent Claim
21 words
The mat of claim 3 wherein the weight of the mat is between 31/2 to 41/2 pounds per fifty square feet.
Claim 9
Dependent Claim
27 words
The mat of claim 3 wherein the thickness is between 3/16 to 1/4 inches and the weight is between 31/2 to 41/2 pounds per fifty square feet.
Claim 10
Dependent Claim
10 words
The mat of claim 3 wherein said mat is rolled.
