may be discovered by touch by drawing the wire between


the thumb and finger. The jagged character of the edge


may be seen only under the microscope, but often may be


detected by running the thumbnail across the edge of the


eye or slots.


To finish these holes and edges to reduce the chafIng


of the yarn to the absolutely possible minimum has been


the object of our research and manufacturing departments


during the thirty years we have been making Warp Stop


Motions and Drop Wires.


HOW DROP WIRES ARE MADE


It is comparatively easy to produce a Drop Wire that


will pass the test of thumb and finger touch. Punching


and a limited amount of flat grinding will do this. So


made, Drop Wires will reduce loom production until they


have been polished by your warps.


The methods used in making Draper Mirror Drop Wires


are designed to insure maximum loom production even


when the wires are new.


After punching, the wires are rattled in sawdust to


remove all oil used in punching.


The next process is the grinding of the thread hole,


bar slot and punched edges to remove all burrs and give


the proper beveled and polished edges. This is done by


skilled operatives with rapidly revolving emery sticks and


ingenious devices to regulate the bevel. Both the skill of


the workman and our specially- designed machines


contribute to satisfactory results in this process.


Inspection of each individual wire follows this process.


After inspection the wires are placed in comparatively


small compartments in our large rattling machines and


rattled with specially prepared grinding and polishing chips


for six days continuously. The compartments are opened


and the condition of the wires examined every day.


Each lot of wires undergoes further inspection when


removed from these rattlers. The final process of the
