Abstract
Abstract A device feeds thread into a winding and traversing mechanism of a winding machine. The thread is fed to a spool via a traversing device having a thread guide and a reverse thread roller. The start of the thread is fed to an entrainment means via a slot that is open at one end in the winding machine. The device is a combination which comprises a traversing device housing rotatably mounted on the winding machine and a mechanism for effecting rotatable adjustment of the housing about a longitudinal axis.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
192 words
A device for feeding thread into a winding and traversing mechanism of a winding machine having an entrainment means and a slot wherein the thread is fed to a spool via a traversing device having a thread guide and a reverse thread roller and the start of the thread is fed to said entrainment means via said slot that is open at one end in the winding machine, the combination comprising: (a) a traversing device housing rotatably mounted on the winding machine; and (b) rotational adjustment means for rotating the housing about a longitudinal axis into an operating position wherein the traversing device is guiding the thread during the winding operation of said winding machine and out of said operating position before said guiding of the thread starts; (c) said rotational adjustment means being effective to rotate the traversing device housing through an angle about said longitudinal axis when the start of said thread is brought into said slot; (d) said angle being such that the thread guide of the traversing device lies outside a vertical plane tangential to said housing to prevent premature engagement of said thread by the thread guide.
Claim 2
Independent Claim
192 words
A device for feeding thread into a winding and traversing mechanism of a winding machine having an entrainment means and a slot wherein the thread is fed to a spool via a traversing device having a thread guide and a reverse thread roller and the start of the thread is fed to said entrainment means via said slot that is open at one end in the winding machine, the combination comprising: (a) a traversing device housing rotatably mounted on the winding machine; and (b) rotational adjustment means for rotating the housing about a longitudinal axis into an operating position wherein the traversing device is guiding the thread during the winding operation of said winding machine and out of said operating position before said guiding of the thread starts; (c) said rotational adjustment means being effective to rotate the traversing device housing through an angle about said longitudinal axis when the start of said thread is brought into said slot; (d) said angle being such that the thread guide of the traversing device lies outside a vertical plane tangential to said housing to prevent premature engagement of said thread by the thread guide.
Claim 3
Dependent Claim
29 words

Claim 4
Dependent Claim
16 words
A combination as defined in claim 2 wherein said guide means is a projecting guide finger.
Claim 5
Dependent Claim
25 words
The combination as defined in claim 1 wherein stops are disposed on the winding machine; and the traversing device housing is rotatable between said stops.
Claim 6
Dependent Claim

Claim 10
Dependent Claim
24 words
The combination as defined in claim 8 wherein the housings are formed integrally and are connected together so as to be rotatably adjustable together.
Claim 11
Dependent Claim
125 words
A traversing device for a winding machine comprising: (a) a reverse thread roller; (b) a thread guide drivable by said roller to and fro axially of the roller; and (c) a roller housing having an axial slot through which the thread guides project; (d) said housing being rotatably adjustable axially about said roller; (e) a fluid pressure operated ram connected to said housing; (f) said ram being effective to rotate the housing about a longitudinal axis into an operating position wherein the traversing device is guiding the thread during the winding operation of said winding machine and out of said operating position before said guiding of the thread starts; (g) said housing being synchronously rotated with the introduction of the thread into the winding machine.
Claim 12
Dependent Claim
125 words
A traversing device for a winding machine comprising: (a) a reverse thread roller; (b) a thread guide drivable by said roller to and fro axially of the roller; and (c) a roller housing having an axial slot through which the thread guides project; (d) said housing being rotatably adjustable axially about said roller; (e) a fluid pressure operated ram connected to said housing; (f) said ram being effective to rotate the housing about a longitudinal axis into an operating position wherein the traversing device is guiding the thread during the winding operation of said winding machine and out of said operating position before said guiding of the thread starts; (g) said housing being synchronously rotated with the introduction of the thread into the winding machine.
Claim 13
Dependent Claim
63 words
A combination as defined in claim 1 wherein the winding machine includes a reserve winding device and a movably adjustable finger means for feeding thread supplied through said slot to said winding device; said finger means being movable between an advanced position and a retracted position; said housing being rotated into said operating position when said finger means is in the retracted position.
