To provide a method of packing a compression molding by a motion where a rope winding and a film winding are alternately performed and a motion where only the film winding is performed by using one film roll and to provide a film feeder for a packing device of the same.

While the compression molding is extruded in a right angle direction to a compression direction received at the time of the molding, by one plastic roll film which is fed through a film width changing device from one film feeder rotating round the compressing molding, after four cubical faces are covered by spirally winding the film while repeating the rope winding where the film is constricted and the film winding where the film is not constricted alternately, and the periphery including two unpacked faces are packed by performing film winding with a plastic roll film fed from the film feeder to pack the whole periphery of the compression molding while the compression molding is rotated.
