1. An adhesive film production apparatus for producing reel bodies of an adhesive film having an adhesive layer that substantially covers a base material layer,
the adhesive film production apparatus comprising:
a feeding roller configured to continuously feed a raw film of the adhesive film;
a cutting part configured to cut the raw film of the adhesive film into a plurality of cut adhesive films having predetermined widths; and
a plurality of winding cores configured to wind each of the plurality of cut adhesive films,
wherein each winding core among the plurality of winding cores has a width greater than a width of a corresponding cut adhesive film to be wound around the winding core, and
wherein a central position in an axial direction of each winding core is shifted from a central position in a width direction of the corresponding cut adhesive film.
