Abstract
Abstract A protective web for use in the manufacture of garments to reinforce parts of the garments corresponding to parts of the human body most likely to be exposed to scratching or fleshing of the skin or muscles. This web is characterized in that it comprises a piece of fabric that may be a woven, knitted or non-woven textile or yet be made of synthetic material. A plurality of small rigid platelets capable of resisting wear and abrasion are secured over this piece of fabric. The small platelets are so uniformly distributed and spaced over the piece of fabric as to allow the web to yield under all movements of the body of the garment wearer. According to a preferred embodiment, the rigid platelets are made of polymeric thermoplastic or thermosetting material and are secured to the fabric by gluing, compression molding or yet by welding in the case where the fabric used is made of synthetic material.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
104 words
A protective web for use in the manufacture of a garment for reinforcing parts of said garment located where portions of the human body are most likely to be exposed to scratching or fleshing, said web comprising: a piece of fabric made of synthetic material and a plurality of small rigid platelets welded on said synthetic material, wherein said platelets are made of a polymeric, thermoplastic or thermosetting material capable of resisting wear and mechanical abrasion and are so distributed and spaced on said piece of fabric as to allow said web to yield under all movements of the body of the garment wearers.
Claim 2
Dependent Claim
104 words
A protective web for use in the manufacture of a garment for reinforcing parts of said garment located where portions of the human body are most likely to be exposed to scratching or fleshing, said web comprising: a piece of fabric made of synthetic material and a plurality of small rigid platelets welded on said synthetic material, wherein said platelets are made of a polymeric, thermoplastic or thermosetting material capable of resisting wear and mechanical abrasion and are so distributed and spaced on said piece of fabric as to allow said web to yield under all movements of the body of the garment wearers.
