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.
Claims16
A holder for receiving and frictionally securing packages of yarn, wound onto hollow tubes of various inner diameters, comprising:
- (a) a base support, adapted to be attached to a creel for a textile machine;
- (b) a contact arm for contacting an inside wall of a yarn tube, one end of which is rigidly connected to said base support, said contact arm extending from said base support in a cantilevered manner;
- (c) a contoured support arm, a pivot connecting one end of said contoured support arm to said contact arm at a point remote from the point where the end of said contact arm is rigidly connected to said base support and a distal free end extended in the direction of said base support terminating short thereof;
- and
- (d) resilient means interposed between said contact arm and said contoured support arm at a distance from said pivot towards said base support, said resilient means urging the end of said contoured arm which is remote from said pivot away from said contact arm in a manner that said contoured support arm and said contact arm are urged against opposite inside walls of a hollow tube placed about said contact arm and said contoured support arm to secure said hollow tube to the base support.
A holder for receiving and frictionally securing packages of yarn, wound onto hollow tubes of various inner diameters, comprising:
- (a) a base support, adapted to be attached to a creel for a textile machine;
- (b) a contact arm for contacting an inside wall of said yarn tubes, one end of which is rigidly connected to said base support, said contact arm extending from said base support arm in a cantilevered manner including a spacer bar rigidly attached to one side of said contact arm having a surface for contacting the inside wall of said yarn tubes;
- (c) a contoured support arm, a pivot connecting one end of said contoured support arm to said contact arm at a point remote from the point where the end of the contact arm is rigidly connected to said base support arm and wherein a plane taken through the longitudinal axis of said contoured arm also extends through the longitudinal axis of said contact arm and said spacer bar, with said contact arm being interposed between said spacer bar and said contour arm;
- and
- (d) resilient means interposed between said contact arm and said contoured support arm at a distance from said pivot towards said base support, said resilient means urging the end of said contoured support arm which is remote from said pivot, away from said contact arm, whereby said contoured support arm and said spacer bar are urged against inside walls of a hollow tube placed about said contact arm and said contoured support arm to secure said hollow tube against the base support.
A textile yarn package holder for receiving and frictionally securing packages of yarn wound onto a hollow tube comprising:
- (a) a base support, adapted to be attached to a support of an associated textile machine;
- (b) a contact arm for contacting an inside wall of a yarn tube, one end of which is rigidly connected to said base support, said contact arm extending from said base support in a cantilevered manner;
- (c) a contoured support arm, a pivot connecting one end of said contoured support arm to said contact arm at a pivot point remote from the point where the end of said contact arm is rigidly connected to said base support arm;
- (d) said contoured support arm including an outwardly bowed portion for gripping an inside wall of said yarn package tube, and a nose portion having an inclined tube guiding surface extending from said pivot for guiding said yarn package tube onto said outwardly bowed portion;
- and
- (e) resilient means interposed between said contact arm and said contoured support arm at a distance from said pivot towards said base support, said resilient means urging the end of said contoured arm which is remote from said pivot, away from said contact arm, whereby said outwardly bowed portion of said contoured support arm and said contact arm are urged against opposite inside walls of said hollow tube placed about said contact arm and said contoured support arm to secure said hollow tube to the base support.
