Abstract
A film threading device for use with cameras and/or projection devices is adapted to grasp the end of the outer convolution of a roll of film, tape or the like strip and guide it toward the film gate. In operation, first and second movable members, such as belts or pulleys, engage the periphery of the wound strip. The first movable member provides the film drive causing the wound film to rotate in an unwind direction. The second movable member provides a stripping action which drives the leading edge of the wound film away from a core and the film is guided by the moving member toward the nip of a thread pressure roller and a thread drive roller. The film is then guided to the film gate.
