Abstract
Abstract A flexible coated abrasive sheet material having abrasive grains adhesively bonded to at least one side of a backing comprising at least one array of non-interlaced substantially coplanar and coparallel reinforcing textile yarns, said textile yarns, together with the yarns of all other distinct arrays, if any, furnishing most of the tensile strength of said coated abrasive in at least one direction in the plane of said flexible coated abrasive sheet material, each said one or more distinct arrays being of non-interlaced, substantially coplanar and coparallel reinforcing textile yarns present in the backing and oriented in the same direction.

Claim 1
Independent Claim
99 words
A flexible coated abrasive sheet material having abrasive grains adhesively bonded to at least one side of a backing comprising at least one array of non-interlaced substantially coplanar and coparallel reinforcing textile yarns, said textile yarns, together with the yarns of all other distinct arrays, if any, furnishing most of the tensile strength of said coated abrasive in at least one direction in the plane of said flexible coated abrasive sheet material, each said one or more distinct arrays being of non-interlaced, substantially coplanar and coparallel reinforcing textile yarns present in the backing and oriented in the same direction.
Claim 2
Dependent Claim
99 words
A flexible coated abrasive sheet material having abrasive grains adhesively bonded to at least one side of a backing comprising at least one array of non-interlaced substantially coplanar and coparallel reinforcing textile yarns, said textile yarns, together with the yarns of all other distinct arrays, if any, furnishing most of the tensile strength of said coated abrasive in at least one direction in the plane of said flexible coated abrasive sheet material, each said one or more distinct arrays being of non-interlaced, substantially coplanar and coparallel reinforcing textile yarns present in the backing and oriented in the same direction.
Claim 3
Dependent Claim
89 words
