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. One end (148) of the second contoured support arm extends beyond the tube contact surface of the contact arm for a slight distance and the other end (147) of the second contoured arm extends towards the base support at an acute angle to the longitudinal axis of the contact arm.
