Take-up reel for metallic filaments

Abstract

A metallic-filament take-up reel by which a metallic filament wound on a winding drum is retained inside at least one of flanges thereof. The reel comprises a winding drum; two flanges in at least one of which there are formed an access hole and a concavity indented from inside toward outside the flange and having a slit formed vis-a-vis to the access hole; and a metallic-filament retainer so rigid and resilient as to catch a metallic filament, provided as secured to the flange and composed of a hook portion which is to be moved through the access hole to catch a metallic filament, a base portion and an intermediate portion rising from the base portion and extending contiguously between the hook and base portions; the retainer being fixed at the base portion thereof to the flange after inserted through the slit from the outer circumference of the flange; the intermediate portion being able to be bent as pushed, when the retainer is used, until the hook portion looking at the access hole moves through the access hole to the winding-drum side from outside toward inside the flange to resiliently retain a trailing end portion of a metallic filament wound on the winding drum.
