A roll feed device includes a rotatable main roll, and a rotatable sub-roll. The main roll includes an annular stator, and an annular rotor rotatably mounted around the annular stator. The annular stator and the annular rotor cooperate with each other to provide a direct drive motor. The sub-roll includes a rotatable annular roll disposed in opposed relation to the annular rotor of the main roll. A sheet-like material is supplied between the annular rotor and the annular roll to be fed.
