Abstract
Abstract The invention is specifically concerned with an improvement in the process of manufacturing reinforced materials. The reinforced materials are conceived to include a wide variety of materials, the most notable being high density compressed gaskets. The improvement comprises mixing a cut solid (generally a cut fiber) with a body material to produce the reinforced materials. The solid is cut into particulates of highly variable size, the range in the size of the particulates being adjusted to optimize the characteristics of the resulting reinforced material. The cut solid is produced utilizing comminuting machines previously used for the recycle of waste products.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
77 words
In the process of producing reinforced materials wherein a solid product is mixed with a body material, which mix is then treated to form the reinforced material, the improvement which comprises: mixing a solid product which is comprised of cut solid which is of small and highly variable size, the cut solid being of a specific small and highly variable size distribution which allows an enhanced degree of mixing of the solid product with a body material.
Claim 2
Dependent Claim
77 words

Claim 10
Dependent Claim
47 words
An improvement in the method of producing reinforced materials as described in claim 5, wherein the ministaple has a distribution of lengths so that, on a weight basis, the proportion of ministaple above the median length is greater than the proportion of ministaple below the median length.
Claim 11
Dependent Claim
47 words
An improvement in the method of producing reinforced materials as described in claim 5, wherein the ministaple has a distribution of lengths so that, on a weight basis, the proportion of ministaple below the median length is greater than the proportion of ministaple above the median length.
Claim 12
Dependent Claim
45 words
An improvement in the method of producing reinforced materials as described in claim 5, wherein the ministaple is a product blend of a first cut fiber product with at least one second cut fiber product wherein at least one cut fiber product is a ministaple.
