FIELD OF INVENTION:
[001) The present invention relates to the field of watch dial. The present
invention in particular relates to a system and method for device for straightening
bush/ feet of time pieces dial which gets bent during manufacturing process
5 DESCRIPTION OF THE RELATED ART:
[002) With respect to the printed dial, there are generally two (2) manufacturing
methods: (I) the Butler-finishing method which presents a hairline design; and (2)
a radial design method which utilizes a stamping or pressing process.
[003) The Butler-finishing method starts with a nickel copper alloy base plate
10 shown at FIG. I-A as base plate 1. Then feet 2 are provided on the base plate 1.
Two methods are presently used for providing feet on the base plate. The first
method utilizes silver wax and in which feet 2 made of a copper pipe filled with
silver wax are implanted in the base plate I. The base plate and the feet are
maintained at 800° C. for five (5) minutes in a furnace until the silver wax withiri.
15 the copper pipe melts and the feet are fixed on base l.
[004) The second method for fixing the feet on the base is the use of resistance
welding. By this method feet 2 having a sharpened end of dull copper are welded
to the base l by applying electric current between the feet and the base while
some pressure is subjected thereto. The principle of this method is that because of
20 the resistance of the sharpened end portion of the feet is very large, the end
portion is specially heated and the feet are fixed to the base.
