Abstract
Abstract To permit ready reversal of rotation of a yarn supply drum, and to positively guide yarn being drawn off the drum, a thread guide element in form of a finger is located laterally offset with respect to the axis of rotation of the storage drum, extending essentially in a direction transverse to a tangential plane at the pull-off point of the yarn, the lateral offset being changeable to either side of the pull-off point to accomodate different directions of rotation of the drum, with simple change-over of the yarn guide finger, for example by re-positioning a mounting plate to extend either towards the left or the right from a support arm.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
180 words
Thread supply apparatus for positive thread supply, for use with textile machines, comprising a support frame (8, 14); a rotatable yarn supply storage drum (1) journalled in the support frame for rotation in a clockwise or counter-clockwise direction. means supplying yarn to said drum (1) to form a stack of supply windings (27) thereon, the yarn being drawn off over the end of the drum from a pull-off position; a thread break sensor (28) in the path of the yarn and engaged thereby; a depending arm (14) extending from said frame and adjacent said drum and stationary thread guide means (15) at the end thereof beneath the drum and offset from the axis of the drum; and a thread guide element (23) including a pin-like finger (33) which is located below the drum (1) in the path of the thread adjacent the pull-off position, and upwardly of the thread guide means (15) and extends in a direction substantially parallel and laterally offset, with respect to a plane containing the axis of rotation of the drum and said guide means (15).
Claim 2
Dependent Claim
180 words
Thread supply apparatus for positive thread supply, for use with textile machines, comprising a support frame (8, 14); a rotatable yarn supply storage drum (1) journalled in the support frame for rotation in a clockwise or counter-clockwise direction. means supplying yarn to said drum (1) to form a stack of supply windings (27) thereon, the yarn being drawn off over the end of the drum from a pull-off position; a thread break sensor (28) in the path of the yarn and engaged thereby; a depending arm (14) extending from said frame and adjacent said drum and stationary thread guide means (15) at the end thereof beneath the drum and offset from the axis of the drum; and a thread guide element (23) including a pin-like finger (33) which is located below the drum (1) in the path of the thread adjacent the pull-off position, and upwardly of the thread guide means (15) and extends in a direction substantially parallel and laterally offset, with respect to a plane containing the axis of rotation of the drum and said guide means (15).
Claim 3
Dependent Claim
66 words
Apparatus according to claim 1, comprising an attachment plate (34) located adjacent and below the drum and extending in a direction essentially parallel to a plane tangential to said drum and transverse to said plane through the axis of rotation of the drum, the finger (33) being secured at one end to said plate (34) at a location laterally offset with respect to said tangential plane.
Claim 4
Dependent Claim
39 words
Apparatus according to claim 2, wherein the attachment plate is shiftable parallel to said tangential plane to place the laterally offset securing position of the finger (33) at either side of said plane through the axis of the drum.
Claim 5
Dependent Claim
35 words
Apparatus according to claim 3, further comprising guide means (36) in said arm (14) locating the attachment plate (34) thereon in selected position at either side of said plane through the axis of the drum.
Claim 6
Dependent Claim
45 words
Apparatus according to claim 4, wherein the finger (33) comprises an essentially cylindrical ceramic element having a hard surface and is located spaced from, but closely adjacent to the bottom (200) of the drum (1) and extends essentially parallel to the bottom of the drum.
Claim 7
Dependent Claim
25 words
Apparatus according to claim 4, wherein the attachment plate is a strip plate (34) and the guide means (36) is a longitudinal groove or track.
Claim 8
Dependent Claim
13 words
Apparatus according to claim 1, wherein the finger (33) comprises a cylindrical pin.
Claim 9
Dependent Claim
19 words
Apparatus according to claim 1, wherein the finger (33) comprises an essentially cylindrical ceramic element having a hard surface.
Claim 10
Dependent Claim
28 words
Apparatus according to claim 1, wherein the finger (33) is located spaced from, but closely adjacent to the bottom (200) of the drum, and extends essentially parallel thereto.
Claim 11
Dependent Claim
29 words
Apparatus according to claim 1, wherein the thread bread sensor (28) is located in the path of the yarn-- in the direction of yarn travel-- below the finger (33).
Claim 12
Dependent Claim
17 words
Apparatus according to claim 8, further comprising means locking the thread break sensor in predetermined locked position.
