Claim 3:
4. The film wrapping machine of claim 1, wherein the inner finger roller includes:
an upper inner finger roller rotatably mounted to be brought into contact with the inner surface of the stretch film opened at the upper end of the inner support plate extending vertically from the end edge of the second horizontal moving plate; and
a lower inner finger roller rotatably mounted on the inner support plate at a position spaced downward from the upper inner finger roller,
wherein the rotating piece includes a main rotating piece having a lower portion hinge-coupled to the second horizontal moving plate and extending upward, and
a sub-rotating piece connected to a rod of a lifting and lowering cylinder so as to be vertically movable with respect to the main rotating piece,
the gripping drive motor and the gripping roller are mounted on the sub-rotating piece, and
the controller controls the clamping cylinder so that all of the gripping roller and the upper and lower inner finger rollers are brought into contact with each other when the gripping roller is rotated so that the stretch film is accommodated under the inner finger roller in a wrinkled manner, and controls the lifting and lowering cylinder so that only the gripping roller and the upper inner finger roller are brought into contact with each other in a process of covering the product with the stretch film in the process of being lowered along the vertical bars.
