PURPOSE: An apparatus for constantly supplying strip to fin mill machine is provided to constantly maintain speed of strip supplied to forming roller to produce products having good quality by decreasing or increasing speed of induction motor of uncoiler according to circumstances. CONSTITUTION: The apparatus comprises an upper front roller that is free rotationally mounted on the front of fin mill die to smoothly transfer strip; an upper rear roller(20) that is free rotationally mounted on the fin mill die with being spaced apart from the upper front roller in a certain distance; guide rods(34) respectively installed at lower part of both sides of the fin mill die; a dancing roller(30) clamped to the guide rods by guide bushing so that the dancing roller is vertically slid; and a sensor(40) at a lower part of which an induction coil embedded sensor frame(42) is installed, and in which a moving sensor(43) connected to dancing roller bracket(35) and formed of permanent magnet is clamped to the sensor frame so that the moving sensor controls speed of induction motor of uncoiler by sensing position of the dancing roller according to difference of induction current as the moving sensor is being moved up and down, thereby transmitting signals to the uncoiler.
