Spool hub for tape cartridges or the like

Abstract: A spool hub for tape cartridges or cassettes, especially sound recording tape cartridges provided with slide or anti-friction foils, wherein the hub body is equipped with passageways or openings distributed at or over the circumference of the hub body. The passageways are advantageously located between blade-like webs. With this construction there is particularly reduced the friction between the spool and the slide or anti-friction foils, so that there prevail lower temperatures and there is accomplished a reduction of the undesired noise level.
