Abstract
Abstract A mat for growing lawns or other vegetation comprising a continuous web sheet of organic fiber such as sphagnum peat moss with lawn or other seeds impregnated therein is formed by feeding the web sheet through drive rollers and past a scarfer. The scarfer removes the surface fiber of the sheet by abrasion, and the expanded removed fiber is drawn away by air induction and collected. The web then passes through a perforator, and thence to a sprayer which applies a binding substance. The web sheet then goes through a seed spreader which deposits seeds on the sheet with the optimum density, and thence to a peat applicator. The peat applicator deposits on the sheet a blanket of expanded peat fiber collected from the scarfer. The sheet passes through compression rollers which finish the lawn mat, which is then cut to size and taken up on rollers.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
83 words
A method for producing a web sheet seed carrier, comprising the steps of providing a roll stock of nutritive organic fiber, abrading a surface of said roll stock to remove a portion of the fiber thereof, applying a binder substance to said surface, affixing viable seed to the binder substance on said surface of said roll stock, returning said removed fiber portion of said roll stock to said surface of said roll stock, and thereafter compressing said roll stock and returned fiber portion.
Claim 2
Independent Claim
83 words
A method for producing a web sheet seed carrier, comprising the steps of providing a roll stock of nutritive organic fiber, abrading a surface of said roll stock to remove a portion of the fiber thereof, applying a binder substance to said surface, affixing viable seed to the binder substance on said surface of said roll stock, returning said removed fiber portion of said roll stock to said surface of said roll stock, and thereafter compressing said roll stock and returned fiber portion.
Claim 3
Dependent Claim
31 words
The method of claim 1, further including the step of perforating said roll stock with a uniform array of holes before said step of abrading said surface of said roll stock.
Claim 4
Dependent Claim
27 words
The method of claim 1, further including the steps of drawing away said removed fiber by vacuum suction means and retrieving said removed fiber with separator means.
Claim 5
Independent Claim
105 words
A device for producing a continuous web sheet seed carrier, including drive means for feeding a fibrous roll stock through said device, abrading means for abrading a surface of said roll stock and removing a portion of the fiber thereof, means for collecting and storing said removed fiber, means for applying a binding agent to said abraded sUrface of said roll stock, means for dispersing seed on the agent applied to said surface of said roll stock, means for uniformly depositing said stored removed fiber on said dispersed seed, and means for compressing said uniformly deposited stored removed fiber, said seed, and said roll stock.
Claim 6
Independent Claim
105 words
A device for producing a continuous web sheet seed carrier, including drive means for feeding a fibrous roll stock through said device, abrading means for abrading a surface of said roll stock and removing a portion of the fiber thereof, means for collecting and storing said removed fiber, means for applying a binding agent to said abraded sUrface of said roll stock, means for dispersing seed on the agent applied to said surface of said roll stock, means for uniformly depositing said stored removed fiber on said dispersed seed, and means for compressing said uniformly deposited stored removed fiber, said seed, and said roll stock.
Claim 7
Dependent Claim
18 words
The device of claim 4, including perforating means for introducing an array of holes in said roll stock.
