Patent ID: 7441721

Claim:
A welding wire tangling-prevention device for preventing tangling of a welding wire ( 110 ) received in a large-capacity pail pack ( 100 ) in the form of a vertically-extending tube-shaped wound body ( 111 ) including eccentrically-stacked continuous spiral loops, when the welding wire is drawn out from the pail pack ( 100 ), comprising: a ring member ( 11 ) laid on a top surface of the tube-shaped wound body ( 111 ), the ring member ( 11 ) including an outer ring ( 11 a ) having an outer diameter smaller than an inner diameter of the pail pack ( 100 ), and an inner ring ( 11 b ) having an outer diameter smaller than an inner diameter of the outer ring ( 11 a ) wherein the welding wire ( 110 ) is drawn out from the pail pack ( 100 ) and the top surface of the tube-shaped wound body ( 111 ) is lowered, thereby freely lowering the ring member ( 11 ); a plurality of first comb teeth ( 12 a ) extending from an inner circumferential surface of the outer ring ( 11 a ) toward the inner ring ( 11 b ); and a plurality of second comb teeth ( 12 b ) extending from an outer circumferential surface of the inner ring ( 11 b ) toward the outer ring ( 11 a ), whereby the welding wire ( 110 ) is drawn out between the first comb teeth ( 12 a ) of the outer rings ( 11 a ) and the second comb teeth ( 12 b ) of the inner rings ( 11 b ).
