Hereinafter, a specific embodiment of the present invention will be described in detail with reference to the accompanying drawings.

2, the leveler 100 capable of processing the multi-spec material according to the present embodiment includes an upper leveling roller unit 110, an upper load distribution roller unit 120, an upper pressure roller unit 130, A leveling roller unit 140, a lower load distribution roller unit 150, and a lower pressure roller unit 160. [

2 and 3, the upper leveling roller unit 110 has a structure in which a plurality of upper leveling rollers 111 are installed in parallel and spaced apart from each other at a predetermined interval, And presses down the material 1 passing between the upper and lower surfaces of the base material. Of course, the plurality of upper leveling rollers 111 installed on the upper leveling roller unit 110 are independently rotated by the separately provided rotating unit 112 to horizontally move the work 1 in a predetermined direction.

2, the upper load distribution roller unit 120 is installed on the upper leveling roller 111 so as to be in common contact with the adjacent upper leveling rollers 111, And is a component that disperses a load applied to the roller 111. That is, the upper load distribution roller unit 120 has a structure in which a plurality of dispersion rollers are arranged in the horizontal direction, and the dispersion rollers 121 are disposed between the two upper leveling rollers 111 The upper leveling roller 111 and the upper leveling roller 111 are disposed in contact with each other. At this time, the dispersion rollers 121 are installed with idle rollers which can move freely. The rollers 121 are formed to have the same length as the upper leveling rollers 111, effectively absorbing the load applied to the upper leveling rollers 111, It is possible to prevent the leveling roller 111 from being deformed.

2, the upper pressure roller unit 130 is installed on the upper load distribution roller 121_ so as to be in common contact with the neighboring upper load distribution rollers 121, The upper leveling roller unit 130 presses the upper leveling roller unit 110 downward to level the centering part of the dispersion roller unit 120 in the downward direction, (111) are prevented from being deformed and an effective leveling operation is performed.
