Abstract
A holder (18) for receiving and frictionally securing yarn package (12) wound onto tubes of various inner diameters is disclosed. The holder comprises a base support which includes an arm (20) adapted to be attached to the textile machine. Extending at a right angle from the base arm is a cantilever contact arm 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. A spring (34) is interposed between the contact arm (24) and the contoured support arm (28) and urges them apart, and against the inner walls of a yarn tube (13) placed about the contact arm and the contoured support arm.
