Abstract
Abstract A rolled bandage for use in the medical field is illustrated constructed of a foraminous spun bonded strip which has slit edges and wound under tension wherein the strip is formed of spaced continuous extruded cellulose filaments each having portions extending alternately in lengthwise and crosswise directions with loop portions between fuse bonded intersections of the lengthwise and crosswise portions.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
99 words
A rolled bandage comprising: a foraminous non woven elongated strip material rolled in open width; exposed slit edges carried on said strip material; said strip material being formed of spaced continuous extruded filaments of hydrophilic polymer each having portions extending alternately in the lengthwise and crosswise directions; fused bonded intersections of adjacent lengthwise and crosswise portions of respective filaments; and loops in said filaments between said fused bonded intersections in both lengthwise and crosswise portions; whereby slit edges need not be folded and linting is avoided while affording controlled stretchability in the lengthwise and crosswise directions of said strip.
Claim 2
Dependent Claim
99 words
A rolled bandage comprising: a foraminous non woven elongated strip material rolled in open width; exposed slit edges carried on said strip material; said strip material being formed of spaced continuous extruded filaments of hydrophilic polymer each having portions extending alternately in the lengthwise and crosswise directions; fused bonded intersections of adjacent lengthwise and crosswise portions of respective filaments; and loops in said filaments between said fused bonded intersections in both lengthwise and crosswise portions; whereby slit edges need not be folded and linting is avoided while affording controlled stretchability in the lengthwise and crosswise directions of said strip.
Claim 3
Dependent Claim
35 words
The rolled bandage set forth in claim 1 wherein the loops are more pronounced in the crosswise portions than in the lengthwise portions affording more stretchability in the crosswise direction than in the lengthwise direction.
Claim 4
Dependent Claim
14 words

Claim 5
Dependent Claim
22 words
The rolled bandage set forth in claim 3 wherein the strip is tensioned having been elongated by about 3% to about 15%.
Claim 6
Dependent Claim
36 words
The rolled bandage set forth in claim 3 wherein the strip is tensioned having been elongated by at least about 3% and having a weight of from about 20 to about 40 grams per square meter.
