Abstract

Wire 1 is straightened by straightener 2 and gaged by air gage 3 as it is drawn from supply reel 4 by take-up reel 5 driven by motor 6. Gage 3 has a block provided with a first bore through which wire 1 passes and with a second bore intersecting the first bore. The first bore is of a diameter slightly larger than that of the wire. Air is supplied under pressure to the second bore and it flows from the gage block through the first bore. Thus the pressure in the second bore is proportional to the average diameter of wire 1 within the first bore. The air also provides a film or bearing so that little force is applied to wire 1 by gage 3. Fluid manometer 8 is connected to the second bore and contains a colored or opaque liquid column.

Wire Gage and Straightener

Wire 1 is straightened by straightener 2 and gaged by air gage 3 as it is drawn from supply reel 4 by take-up reel 5 driven by motor 6. Gage 3 has a block provided with a first bore through which wire 1 passes and with a second bore intersecting the first bore. The first bore is of a diameter slightly larger than that of the wire. Air is supplied under pressure to the second bore and it flows from the gage block through the first bore. Thus the pressure in the second bore is proportional to the average diameter of wire 1 within the first bore. The air also provides a film or bearing so that little force is applied to wire 1 by gage 3. Fluid manometer 8 is connected to the second bore and contains a colored or opaque liquid column. The latter is sensed by photocells 9 arranged to represent high and low limits for acceptance of the particular wire. The outputs of photocells 9 are fed to tester 10 containing lights 11 for indicating when the diameter of the wire exceeds either limit. Tester 10 also contains controls for shutting off motor 6 when a limit is reached. This allows the defective portion of wire 1 to be removed.
