A spool for thread-type or strip-type wound material in a version for correct-sided insertion into a device, the spool on the one hand having a substantially cylindrical tube-type or cylindrical double tube-type winding core with flange disks of greater diameter arranged at its two ends for forming a winding area, and on the other hand being fittable inside the apparatus in a predetermined operating position with its central mounting bore arranged in the winding core and rotatable about its central axis. To obtain a spool that has on the one hand a simple and inexpensive structure and permits a simple, compact, and inexpensive configuration of the apparatus receiving the spool and on the other hand is versatile in use, i.e. for wound materials of differing winding directions and materials, while at the same time permitting safe and simple handling of the spools with differing wound materials and ensuring the respectively predetermined operating position of the spool inside the apparatus, at least one insertion direction/position determining means at a distance radially from the mounting bore is arranged on the outside of at least on one of the flange disks of the spool such that wrong-sided fitting of the spool on a mounting journal is recognizable and an axial movement of the spool into its predetermined operating position on the mounting journal is preventable when it has been fitted on the wrong side.
