Abstract: A spool system for packing tape on a hub. The spool has upper and lower flanges on the hub, and a flexure positioned on the hub between the two flanges. The flexure is normally parallel to the flanges, but when a force is applied to the tape lead-in edge of the flexure, that edge of the flexure is pressed toward one of the flanges. This causes the tape lead-in side of the spool system to have a wider opening than the tape packing side of the spool system. The width of the space on the tape packing side is preferably equal to or narrower than the width of the tape to be packed, so that the flexure presses against the edge of tape as it loads, reducing stagger of the tape.

Abstract: In an inner surface of a lower flange of the magnetic tape reel, 6 concave portions each shaped in nearly as isosceles triangle are made formed at even angle intervals of 60 degrees with their circumferential cross-section area being larger as approaching to a hub. When a magnetic tape is wound on the hub, air which exists between a tape-winding surface of the hub or the tape already wound and the tape to be wound further is guided to the concave portions, and an amount of wound-in air becomes less in the inner side and large in the outer periphery. Consequently, a pressure of winding the tape tight at the outer periphery does not reach the inner side, so that winding irregularities or deformation of the tape do not occur.

The spool gripper has an inner diameter portion for receiving a spool holder when the spool is fitted to the spool holder, a coupling portion coupled to the circumference of the flange while bearing a diameter larger than the inner diameter portion, and an outer diameter portion with a diameter larger than the coupling portion. The worker grips the outer diameter portion to handle the spool. The handling of the spool can be made without directly touching the spool.

Accordingly, the durability of the gripper and the reliability in the spool holding can be maintained without deterioration while preventing separation of the spool from the gripper.
