Support for coils of cable, welding wire or the like

Abstract

A support is described for coils of cable, welding wire or the like, comprising: a central huh ( 20 ) constituted by two first rings ( 22 ) respectively fixed to the ends of, mutually parallel, rods ( 24 ) of substantially equal length ; two annular flanges ( 30 ) integral respectively with two opposite ends of the hub to define an annular space around the hub inside which to house the coil, the flanges being constituted by two second rings ( 32 ) with larger diameter than the first rings, each second ring being connected concentrically and rigidly to a first ring by radial rods ( 34 ). To avoid accidental injury to the user, the outer edge of at least one end ( 66 ) of each rod comprises a blunting ( 80 ).

1 . Support for coils of cable, welding wire or the like, comprising:
 a central hub ( 20 ) constituted by two first rings ( 22 ) respectively fixed to the ends of, e.g. mutually parallel, rods ( 24 ) of substantially equal length;   two annular flanges ( 30 ) integral respectively with two opposite ends of the huh to define an annular space around the hub inside which to house the coil,   the flanges being constituted by two second rings ( 32 ) with diameter larger than the first rings, each second ring being connected concentrically and rigidly to a first ring by radial rods ( 34 );   wherein the outer edge of at least one end ( 66 ) of each rod comprises a blunting ( 80 ).   
     
     
         2 . Support according to  claim 1 , wherein the blunting consists of a portion inclined by 45 degrees with respect to the longitudinal axis (W) of the rod, or of a rounded portion or with an increased curvature radius. 
     
     
         3 . Support according to  claim 1 , wherein one or each ring consists of a segment bent or curved circularly so that the ends of the segment join or meet. 
     
     
         4 . Support according to  claim 1 , wherein one or each ring is a hollow tubular element. 
     
     
         5 . Support according to  claim 1 , wherein one or each rod consists of a straight or curved segment. 
     
     
         6 . Support according to  claim 1 , wherein one or each rod is a hollow tubular element. 
     
     
         7 . A method for constructing a support ( 10 ) for coils of cable, welding wires or the like, with the steps of:
 taking some rods ( 62 ) and blunting the outer edge of at least one end ( 66 ) of each rod;   attaching the rods to two first rings ( 22 ) and to two second rings ( 32 ) with larger diameter than the first rings, so that   each second ring is rigidly connected concentrically to a respective first ring by radial rod ( 34 ), and the two first rings and the two second rings are concentric, wherein the first rings are connected by road ( 24 ) parallel to each other.   
     
     
         8 . Method according to  claim 7 , wherein the step of blunting comprises the step of removing from the sharp edge of the margin of the rod the extremity prism. 
     
     
         9 . Method according to  claim 7 , wherein the step of blunting comprises the step of beveling or filing or polishing the ends of the rod. 
     
     
         10 . Method according to  claim 7 , wherein the step of blunting occurs during the cutting of a rod ( 62 ) from a longer member ( 60 ). 
     
     
         11 . Method according to  claim 7 , wherein the step of blunting is performed. by cutting said longer member ( 60 ) with a cutting edge ( 72 ) that rotates about the longitudinal axis (Y) of the longer member. 
     
     
         12 . Method according to  claim 7 , wherein the step of blunting generates on said edge an inclined plane or a corner with a radius of curvature greater than or equal to 0.25 mm. 
     
     
         13 . Method to produce rods that make up a support as in  claim 1 , with the step of:
 blunting the outer edge of at least one end ( 66 ) of each rod before fixing the rods to said rings.
