Yarn bobbin holder - has conical surface to hold end of sleeve firmly against carrier arm and allow empty sleeve to drop free when carrier arm is tilted

摘要

A bobbin holder for a bobbin wound with yarn, with a cylindrical and/or conical sleeve, has an angled surface for the counter surface (10) against the end of the sleeve, rising to the free end of the carrier arm (7). The support (11,13) has a free hanging lever with its upper end linked to the carrier arm, with a length to engage the sleeve wall when the sleeve end side (4) is at the counter surface (10). The angled surface (10) has a recess (9) to hold an inner flange (5) of the sleeve (3) at its end side. The angled surface (10) is a conical surface, and the recess (9) is a ring groove to contain the rolling edge formed by the inner flange (5). The lever (11,13) is near the angled surface (10). Two levers (11,13) can be used, with different lengths, with a shorter lever for a conical sleeve and the longer lever for a cylindrical sleeve (3). USE/ADVANTAGE - The assembly is to hold bobbins wound with yarn, with a cylindrical and/or conical bobbin sleeve. The bobbin is held securely at the carrier arm, and the empty sleeve can be released easily to drop free when the carrier arm is tilted.
