Film spool

摘要

A takeup spool includes a spool core having a film supporting surface and a film-catching member projecting from the film supporting surface for securing the filmstrip to the spool. The spool includes a cutout portion preferably adjacent the film-catching member for maintaining the trailing end of the filmstrip in an undeformed state as the filmstrip is being unwound from the spool. The spool also includes a transitional supporting surface for supporting the leader portion of the filmstrip on the spool core in radial conformity with the remainder of the filmstrip.
