Abstract

The present invention relates to a bobbin holder that can fix a bobbin to a spindle, which is an element of a winding apparatus, when fiber yarn is wound using the winding apparatus and, more specifically, to a bobbin holder for winding fiber yarn that can easily fix a bobbin using sleeves mounted on a spindle, chuck rings, and fixing pieces. The present invention provides a bobbin holder for winding fiber yarn, which is mounted in a winding apparatus to firmly hold a bobbin around which fiber yarn is wound, comprising: a motor; a spindle that rotates while being connected to the motor and has an empty space formed therein; a plurality of sleeves mounted on the outer circumferential surface of the spindle; chuck rings, each of which is mounted between the sleeves to interconnect the sleeves; fixing pieces equipped to the chuck rings to firmly hold the bobbin or to release the holding of the bobbin; and a resilient bias part that applies a compressive force to the sleeves and chuck rings.
