A film feeding machine, comprising:
- a frame having a horizontal plate and a vertical plate;
- a film base vertically provided on the horizontal plate of said frame and located in front of the vertical plate, comprising means for carrying a continuous film vertically;
- a feeding device provided on the vertical plate, the feeding device being movable between an extended position and a retracted position along a first axis parallel to the vertical plate and comprising means for holding and transporting the film vertically;
- a drawing device, which is located beside the first axis and faces the feeding device, comprising means to draw the film out of the film base long a path parallel to the first axis to a position for being held by the feeding device;
- a cutting device, which is located beside the first axis and between the feeding device and the film base and faces the feeding device, and comprising means for cutting the film off to have a film piece, and
- wherein the drawing device includes a first drawing member and a second drawing member, wherein the first drawing member is adapted to fix the film drawn out of the film base at a first position and the second drawing member is adapted to draw the film to a second position, in which the film is held by the feeding device, from the first position.
The film feeding machine as defined in claim l, wherein the first drawing member is mounted on the frame and has a turning portion to fix the film along a direction of the film being drawn out of the film base, and the drawing device further includes a first driving device mounted on the frame and movable along a second axis, to which the second drawing member is connected.
