Abstract:
1. An apparatus for manufacturing a sealed flux laminated alloy filler metal, the apparatus comprising: a disc-type supply stand for winding a scroll type filler metal thereon; a mounting stand mounted below the supply stand; an aligning guide hingedly mounted on the mounting stand via a hinge and having an aligning roller for pressurizing the upper end of the scroll type filler metal; a pair of vertical guide rollers and a pair of horizontal guide rollers for supplying a strip of the filler metal loosened from the scroll type filler metal to a pair of tension rollers; a pair of embossing rollers mounted vertically for forming embossed marks on the surface of the filler metal passing through the tension rollers while the filler metal passes therethrough; a pair of V-shaped forming rollers mounted vertically for transforming the filler metal formed with the embossed marks into a V-shaped filler metal while the filler metal passes therethrough; a pair of W-shaped forming rollers mounted vertically for transforming the V-shaped filler metal into a W-shaped filler metal while the filler metal passes therethrough; a flux injector for filling a flux between overlapped surfaces of the W-shaped filler metal; reducing rollers for reducing a horizontal width of the W-shaped filler metal filled with the flux, the reducing rollers being arranged by pairs, wherein an interval between each pair of the reducing rollers, which are arranged correspondingly to each other, is gradually reduced in a conveyance direction of the W-shaped filler metal; a compression roller and a first stereotype roller for further compressing and stereotyping either side of the W-shaped filler metal having the reduced horizontal width, the stereotype roller having a groove formed on the outer peripheral surface thereof; a saw-tooth roller and a second stereotype roller for forming saw-tooth marks on a side surface of the W-shaped filler metal to prevent a leakage of the flux; and a winder for winding the W-shaped filler metal thereon.
