A coating film peeling apparatus for resin material includes: a peeling cylinder, a peeling roll installed therein with a space for a peeling process along an inner wall of the peeling cylinder, a resistance lid disposed to block a discharge port of the peeling cylinder, and a pressure adjustment part for adjusting an outflow rate and internal pressure of the peeling cylinder. The peeling cylinder is constituted by a polygonal-shaped angular columnar body having, as coating film pass-through holes, rows K of small holes and rows L of small holes and projection rings (angular embossments) provided alternately in multiple rows along a direction perpendicular to a rotating direction of the peeling roll.

At least a pair of metal rolls having different peripheral speeds with each other are removably mounted to respective rotary shafts in a cantilever form. The axial length of each of the metal rolls is between 100 and 500 mm and the peripheral speed of the high speed roll is between 12 and 30 meter/second. A cover is fitted to a milling chamber that houses therein the paired metal rolls and has a transparent member at least as a part thereof. With such an arrangement, the rolls can be replaced with ease and the milling operation carried out in the milling chamber can be easily monitored through the transparent member.
