BACKGROUND OF THE INVENTION
[002] Blanking is a metal fabricating process, during which a metal work-piece is removed from the primary metal strip or sheet when it is punched using a press tool. The material that is removed is the new metal work-piece or blank (figure 1 (a).
[003] Publication No. FR2856022 relates to a plate or a unit of a hard steel plate having a shape of a character along a cut line with a laser beam to obtain a punch and a blanking die of the character. The cut has a variable thickness of 0.10 to 0.20 millimeters corresponding, to a diameter of the laser beam of cutting. The die is constituted of a complementary part of the punch on the plate or the unit of the plate. An independent claim is also included for embossing punch and blanking die tools for the formation of the characters on double type number plates.

DETAILED DESCRIPTION OF INVENTIONS
[033] Accordingly, the present invention relates to an improved system for multi-faceting and multi-finishing of watch hands in strips. Multi-finishing of watch hands converts the multi-faceted watch hands surface to different texture by electro plating, lacquer, sand blasting or by a metal brush.
[034] Referring to the figure 1 a system for multi-faceting and multi-finishing of watch hands in strips comprises at least two spindles (0.1), servo motor (02) to rotates the aluminium bed (03) on which hands are arranged over brass fixture (04).
[035] Multi faceting machine is used for cutting one to three faces maximum. The functioning of machine is automatic thus the operator has to feed the fixture plate containing watch hands during each cycle. The watch hands are initially profile blanked and it is immediately pressed backed into the same brass strip which is used for blanking. The brass strip is then cut to the length of the brass fixture and is glued on to the plate using special adhesive. The brass fixture plate has guide pins to locate the brass strip accurately each time, the pilot holes which is Pierced prior to profile blanking operation is used as a reference for locating. The fixture plate is then placed on the machine servo bed which can feed the plate in consecutive positions using servo motor. The pitch can be programmed to requirement. The machine has two spindles. Depending up on the type of operation either one or both spindles can be used simultaneously. When the cycle is on the spindles starts rotating and the bed which is holding the fixture plate travels up. Once faceting operation is completed the bed travels down and moves

to the next pitch. This process is repeated until all the hands on the fixture plate are faceted. If the requirement is more than two faces in the watch hand the fixture plate has to undergo the same operation again.
[036] The invention is described in detail with reference to the examples given below. The examples are provided just to illustrate the invention and therefore, should not be construed to limit the scope of the invention.
EXAMPLES
Example 1
[037] Two tone angle cut finish (Two Face hands) is shown in figiure 2 a and b. One side lacquer and plating finish on the other face finish is done in two setting. At first the brass strip where the hands are pressed back after blanking is fixed on the fixture plate and loaded in the machine. This process uses the first spindle initially which is tilted to get the desired angle for angle cutting. After the first cutting operation the brass strip is removed and is lacquered. The strips are again loaded in the machine and uses second spindle for cutting which is again tilted to get the desired angle on the other side of watch hand. After the second cutting the pressed back hands are removed from the strips and electro plating is done to achieve the desired finish like nickel, gold, black-oxidation or rhodium finishes. The end result will be lacquered finish one side and plated finish on the other.
[038] One side plating and other side brushed finish is done in two setting. At first the brass strip where the hands are pressed back after blanking is fixed on the fixture plate and loaded in the machine. This process uses the first spindle initially which is tilted to get the desired angle for angle cutting. After the first cutting operation the brass strip is removed and undergoes a brushing operation which creates vertical lines on the watch hands. The strips are again loaded in the machine and uses second spindle for cutting which is again tilted to get the desired angle on the other side of watch hand. After the second cutting the pressed back hands are removed from the strips and electro plating is done to achieve the

desired finish like nickel, gold, black-oxidation or rhodium finishes. The end result will be brushed finish one side and plated finish on the other (fig 3).
[039] One side plating and other side sand blasted finishjs done in two setting. At first the brass strip where the hands are pressed back after blanking is fixed on the fixture plate and loaded in the machine. This process uses the first spindle initially which is tilted to get the desired angle for angle cutting. After the first cutting operation the brass strip is removed and undergoes a sand blasting operation which creates a satin finish on the watch hands. The strips are again loaded in the machine and uses second spindle for cutting which is again tilted to get the desired angle on the other side of watch hand. After the second cutting the pressed back hands are removed from the strips and electro plating is done to achieve the desired finish like nickel, gold, black-oxidation or rhodium finishes. The end result will be sand blast finish one side and plated finish on the other (fig 4).
Example 2
Two tone Multi-faceted hands (Three Face hands)
[040] Angle cut in the sides and flat cut finish at the centre is done in two setting. At first the brass strip where the hands are pressed back after blanking is fixed on the fixture plate and loaded in the machine. This process uses the first spindle initially which is set flat to get the flat cutting. The brass strip are again loaded in the machine and uses both spindle simultaneously for cutting which is again tilted to get the desired angle on the both side of watch hand. After the second cutting the pressed back hands are removed from the brass strip and electro plating is done to achieve the desired finish like nickel, gold, black-oxidation or rhodium finishes. The end result will be a three face watch hands with plated finish (fig 5a and 5b).
[041] Angle cut in the sides and sand blasting finish at the centre is done in two setting. At first the brass strip where the hands are pressed back after blanking is fixed on the fixture plate and loaded in the machine. This process uses the first spindle initially which is set flat to get the flat cutting. After the first cutting

operation the brass strip is removed and undergoes a sand blasting operation which creates a satin finish on the watch hands. The brass strip are again loaded in the machine and uses both spindle simultaneously for cutting which is again tilted to get the desired angle on the both side of watch hand. After the second cutting the pressed back hands are removed from the brass strip and electro plating is done to achieve the desired finish like nickel, gold, black-oxidation or rhodium finishes. The end result will be a three face watch hands with plated finish on two sides and sand blast finish at the centre (fig 6).
[042] Angle cut in the sides and brush finish at the centre is done in two setting. At first the brass strip where the hands are pressed back after blanking is fixed on the fixture plate and loaded in the machine. This process uses the first spindle initially which is set flat to get the flat cutting. After the first cutting operation the brass strip is removed and undergoes a brushing operation which creates vertical lines on the watch hands. The brass strip are again loaded in the machine and uses both spindle simultaneously for cutting which is again tilted to get the desired angle on the both side of watch hand. After the second cutting the pressed back hands are removed from the brass strip and electro plating is done to achieve the desired finish like nickel, gold, black-oxidation or rhodium finishes. The end result will be a three face watch hands with plated finish on two sides and brush finish at the centre.
