A welding wire conveyor

摘要

A welding wire advancing device of the type wherein the welding wire to be advanced is taken along between the straight active runs of two conveyor belts that are disposed around rollers positioned at a device entrance and a device exit respectively and are to be driven in opposite directions and wherein auxiliary support rollers for the active belt runs are provided in the advancing part between the device entrance and exit, the auxiliary support rollers for the active run of one conveyor belt being positioned - as seen in the advance direction - offset relative to the auxiliary runs of the other conveyor belt. With this welding wire advancing device an aluminium wire having a thickness of e.g. 0,5 mm can be drawn at high speed (20 m/mm and more) and slippage free from a wire supply, while moreover a straigthening effect occurs, due to which the wire leaves the device completely intact and completely straightened as well.
