A yarn package holder for accommodating yarn package tubes and cones of various sizes, wherein a fixed, cantilevered contact arm is provided with a separate layer of friction material providing a friction surface and has one end of a first spring member pivotally connected to the distal end thereof, and one end of a second spring member fixedly connected to the other end thereof. The friction surface engages the inner wall surface of the tube or cone on one side thereof and the free end of the first spring member engages the inner wall surface of the tube or cone on the opposite side thereof, and the free end of the second spring member engages the first spring member intermediate the ends thereof to provide a displaceable fulcrum therewith. An equal biasing force is applied to the inside surface of the tubes or cones no matter what their size might be.
A holder for receiving and frictionally securing packages of yarn wound onto hollow tubes and cones of various inner diameters comprising, a base support adapted to be, attached to a creel for a textile machine, a contact arm, a seperate layer of friction material applied to said contact arm providing a friction surface thereon for contacting an inside wall of a selected yarn tube and cone, one end portion of said contact arm being rigidly connected to said base support, said contact arm extending from said base support in a cantilevered manner, a first spring member, a pivot connecting one end of said first spring member to the distal end portion of the contact arm, the free end of said first spring member extending in a direction toward the said one end portion of the contact arm, a second spring member positioned between said contact arm and said first spring member, means fixedly connecting one end of said second spring member to the said one end portion of said contact arm, said second spring member extending from said fixed connection in a direction toward the distal end portion of the contact arm, the other end of the second spring member engaging the first spring member to form a displaceable fulcrum therewith, the second spring member biasing the first spring member radially outwardly of said contact arm, whereby the friction surface on the contact arm and the free end of said first spring member are urged against opposite inside wall surfaces of the selected tube and cone, to thereby hold the selected tube and cone on the holder while applying an equal biasing force to the inside surface of the tubes and cones no matter what their size might be.
