  • Patent number: 4760977
    Abstract: A holder (18) for receiving and frictionally securing a yarn package (12) wound onto tubes of various inner diameters. The holder comprises a base support which includes an arm (20) adapted to be attached to a textile machine. Extending at a right angle from the base arm is a cantilever contact are (24) which is rigidly connected to the base. The contact arm has a contoured support arm (28) pivotally connected to its free end and extending alongside the contact arm to a point near the base support which is biased outward by a spring (34). A second embodiment (118) has two contoured support arms, one (128) of which is pivotally connected to the contact arm (124) at a point (127) intermediate a free end portion. A resilient second contoured support arm (143) is affixed to the end of the contact arm and has a portion which extends generally transverse over the longitudinal axis of the contact arm.
