PURPOSE: To provide a coil material feeding apparatus provided with a leveler (a material correcting function part) in which a setting angle can be adjusted. CONSTITUTION: The coil material feeding apparatus comprises a coil material feeding portion(22) including a pair of feeding rollers(14,15) arranged on an upstream side of a material inlet in the intermittent feeding apparatus and feeding the material to the intermittent feeding apparatus while forming a proper loop in the material, a servo motor(16) driving the feeding rollers, a material correcting portion(19) structured such that upper and lower roller lines having a plurality of rollers(18) respectively arranged approximately in a line and at alternately shifted positions in an advancing direction allow the coil material fed toward the intermittent feeding apparatus to pass through a gap between the upper and lower roller lines, and placed on an upstream side or a downstream side of the feeding rollers, and a height adjusting mechanism(20) adjusting a distance of the gap between the upper and lower roller lines in the material correcting portion; a position sensor(23,24) provided on a downstream side of the coil material feeding portion and detecting a loop amount of the coil material; a control apparatus(26) controlling the servo motor on the basis of a signal output from the position sensor so as to control a feeding amount of the coil material by the feeding rollers; and a stand(25) holding the coil material feeding portion in a state in which a mounting angle of the coil material feeding portion is adjustable in such a manner as to change a feeding angle of the material in correspondence to a condition.
