Durable slings for vehicle frame turnover machines and method of making the slings
First Claim
1. A webbing sling comprising a woven nylon webbing with a first end, a second end, a top surface, a button surface, a first webbing side and a second webbing side;
- a first abrasion resistant cover encasing a first tongue portion adjacent to the first end and sewn to said woven nylon webbing;
a first eye formed by folding the first tongue portion and the first abrasion resistant cover and sewing the first end to said woven nylon webbing;
a second abrasion resistant cover encasing a second tongue portion adjacent to the second end and sewn to said woven nylon webbing;
a second eye formed by folding the second tongue portion and the second abrasion resistant cover and sewing the second end to said woven nylon webbing;
a strip of woven material with an abrasion resistant surface, a first strip side and a second strip side sewn to the top surface of said woven nylon webbing;
a urethane cover that adheres to the top surface of said woven nylon webbing, to the first webbing side of said woven nylon webbing, and to the second webbing side of said woven nylon webbing and that leaves at least a portion of the abrasion resistant surface of said strip of woven material exposed.

Abstract
The webbing sling has a woven nylon webbing member with a top surface, a bottom surface, a first webbing side, a second webbing side, a first eye on one end and a second eye on the other end. A strip of abrasion resistant woven material with a high coefficient of friction is sewn to the top surface of the woven nylon webbing. A liquid urethane is applied to the top surface, the first webbing side and the second webbing side between the first and second eyes. The upper face of the strip of abrasion resistant material is free of urethane. Both eyes are covered by woven abrasion resistant covers that are sewn to the woven nylon webbing and then covered by urethane.
