Description:

The present invention relates to apparatus for moistening yarn such as textile thread and more specifically pertains to means for transferring liquid from one or more rotating rollers to a longitudinally moving thread or yarn.

An object of the invention resides in providing means for supplying a suitable conditioning liquid to textile fibers in the form of a thread or yarn before the thread or yarn is stored on a carrier or wound on a bobbin.

Another object of the invention resides in providing moistening apparatus wherein the quantity of liquid transferred to a textile thread or yarn may be readily varied.

A still further object of the invention includes the provision of a roller adapted to be tangentially engaged by a longitudinally moving thread, or yarn and means for supplying liquid in the form of a film to the periphery of the roller and means for controlling the quantity of liquid carried by the periphery of the roller.

A more specific obiect of the invention resides in providing a plurality of rollers each carrying a film of conditioning liquid including means for selectively moving the rollers into engagement with the thread so as to control the quantity of conditioning liquid transferred to the thread or yarn.

Another and more specific object of the invention includes a roller and means for driving the roller at different speeds including means. for suDplying a film of liquid to the periphery of the roller and a second roller movable into frictional engagement with the first roller so as to be driven thereby and receive a film of liouid from the driving roller with both of the rollers engaging the thread to be moistened.

Other features and objects of the invention will be apparent from a consideration of the accompanying drawing and the following detailed description wherein an exemplary embodiment of the invention is disclosed.

In the drawing: Fig. 1 is a general organization view illustrating the moistening apparatus in elevation and partly in section.

Fig. 2 is a perspective view of the main roller and means for imparting a film of liquid to the perinhery thereof.

Fig. 3.is a sectional view of the moistening apparatus taken on line III-III of Fig. 1.

Fig. 4 is an end elevational view of the moistening .apparatus.

Fig. 5 is an elevational view of the opposite end of the moistening apparatus.

Fig. 6 is a longitudinal sectional view of one of the rollers of the' moistening apparatus.

Referring to the drawing there is shown in Fig. 1 at 10 a spool or bobbin of a conventional type onto which the thread may be stored by winding the thread on the bobbin 10. The bobbin may be driven by means of a shaft II which is rotatably supported in winding apparatus in a well known manner. The bobbin 10 is preferably arranged in a horizontal manner above the moistening apparatus hereinafter described so that rotation of the shaft II will cause the thread to move longitudinally in an upward direction.

In carrying out the invention a roller 12 is supported for rotation within a frame 14 which includes two end plates 16 and 17. The roller 12 is suitably journaled in the end plates IS and 17. A shaft 18 is provided for driving the roller 12. Power is transferred to the shaft 18 from a driven shaft 19. Suitable means may be provided between the shaft 19 and the shaft 18 for varying the speed of the roller 12. Such speedvarying means may take the form of reversed cone pulleys 21 connected by means of a belt 22 Sas shown in Fig. 1.

The invention includes means for supplying a film of liquid to the periphery of the roller 12.

Such means may consist of a wick 23 formed of any suitable material such as felt but the wick may be formed of sponge or chamois or like materials. The wick 23 preferably extends along the entire length of the roller 12 as shown in Fig. 2. The wick is supported in an operable position adjacent the roller 12 by means of an elongated cup-shaped member 24 which may be substantially U-shaped in section and extends along the entire length of the wick 23. Liquid is supplied to the wick 23 from a tank or container 26 connected to the member 24 by means of a flexible tube 27. The elongated cup-shaped member 24 may be regarded as a trough and is supported in such a manner than the liquid supplied thereto will be retained therein and absorbed by the wick 23. The tank 26 is adapted to receive a supply of suitable conditioning liquid for the textile thread or yarn and the container 26 is mounted so as to be raised or lowered with respect to the wick 23 and the roller '12 by any suitable means such as a threaded shaft 28 and a handwheel 29. The pressure of the liquid supplied to the wick 23 may thus be varied by raising or lowering the tank 26. Thus the quantity of liquid conveyed to the periphery of the roller 12 may be varied by changing the position of the tank 26.

The wick means may also extend from the trough 24 into the tank 26 as shown in Pig. 1.

The tank 26 may then be lowered below the level of the trough 24 but liquid or moisture will be transferred from the tank to the roller 12 by capillary action of the wick portion 25 in the tube 27.

The wick 23 engages the periphery of the roller 1W I1 and the pressure of the wick 23 on this roller may be varied by suitable means. Such pressurevarying means may be formed in the supporting means for the member 24. Thus for example, the elongated cup-shaped member 24 holding the wick 23 may be supported on the frame 14 by means of screws 31 which terminate in knobs 32.

Thus, the quantity of liquid transferred to the roller 12 may be varied by adjusting the screws 31 to alter-the pressure of the wick 23 on the roller.

In carrying out the invention a thread or yarn 34 to be stored on the bobbin 10 is guided transversely over the periphery of the roller 12 carrying the film of liquid. The thread 34 is maintained substantially in tangential engagement with the periphery of the roller 12 by means of a fixed thread-guide 36 such as a slub catcher of a winding machine. The thread-guide or slub catcher 36 is preferably arranged below the approximate mid-point of the roller 12. The thread 34 is preferably moved in an upward direction over the roller J 2 by rotation of the bobbin 10 and guided onto the rotating bobbin by means of a second thread-guide 38. The moistening apparatus or the roller 12 is so positioned with respect to the bobbin 10 and the thread-guide 31 that the thread or yarn 34 will be constantly maintained in engagement with the periphery of the roller 12. The thread-guiding means 37 is also reciprocated longitudinally of the moistening apparatus so as to properly guide the thread 34 onto the bobbin 10. Such reciprocating movement of the thread-guiding means 37 may be accomplished by means of a. cam I which may be driven from the power source driving the shaft 11. The reciprocation of the thread-guide 37 also causes the thread 24 to be bodily moved lengthwise of the moistening apparatus or the roller 12 and at the same time maintain the thread in engagement with the periphery of the roller 12 as the thread is bodily moved along the length of the roller 12.

A second roller 42 is provided adjacent the roller 12. This roller 42 is mounted for rotation on bearings 41 and a shaft 43 carried by spaced arms 48 as shown in Fig. 6. The arms 48 are secured to a shaft 51 which is journaled in the end plates 16 and 17. The shaft 43 ext'-..ds beyond each end of the roller 42 and these ends project through slots 46 in the end plates I1 and II7 The roller 42 may therefore swing on the shaft 51 so that the periphery of the roller 42 frictionally engages the periphery of the roller 12. A part of the liquid carried by the roller 12 is therefore conveyed to, the roller 42 and the roller 42 is rotated by the frictional engagement thereof with the roller 12. In such a position as shown in Fig. 3, the roller 42 is adapted to engage the longitudinally moving thread 34 and transfer additional liquid from the periphery thereof to the thread or yarn.

The roller 42, however, may be retracted from the position illustrated in Fig. 3 by means of a handle 52 carried by an arm 48. When the handle 52 is raised the ends of the shaft 43 move in the slots 46 so that the roller 42 may be moved from engagement with the roller 12 and also from engagement with the thread 34. The roller 42 may be retained in the retracted position by means of a lever 53 pivotally mounted on the end plate I7. The lever 53 is provided with, an arcuate recess 54 for partly embracing this end of the shaft 43 in an elevated position in the slot 46.

The lever 53 is provided with a further arcuateshaped recess 56 for retaining the shaft 43 in a lowermost position in the slot 46.

A third roller 57 may be provided for receiving liquid from the periphery of the roller 42 and the roller 57 is also driven by frictional engagement with the roller 42. The roller 57 is pivotally mounted in a manner similar to the arrangement shown and described in connection with the roller 42. Thus, by raising the arm 58 the- roller 57 .may be removed from engagement wwi~t the thread 34 and from.engagement with the roller 12 and retained in such retracted position by rn. ;ns of a lever 60 pivotally mounted on Sthe end p:.;e I adjacent a shaft 6 i for the roller 5.. The I 'ers 53 and 60 are yieldably biased by means of spring 62.

Thus, th : quantity of liquid transferred to the thread or ya ~ 34 may be further varied by employing the roller 42 in addition to the roller 12 and a still larger quantity of liquid may be conveyed to the thread or yarn 34 by moving the roller 57 into frictional engagement with the roller 42 and into engagement with the thread 34. Under such circumstances the liquid film supplied to the roller 12 will in part be transferred to the roller 42 and a portion thereof conveyed therefrom onto the periphery of the roller 57. The liquid carried by all three rollers will therefore be transferred to the longitudinally moving thread or yarn 34.

It is to be further noted that the speed at which the rollers 42 and 57 are driven may also be varied by the speed-changing arrangement .between the shafts 18 and 19 since the roller 42 is driven by the roller 12 and the roller 57 is driven by the roller 42. The liquid transferred to the rollers 42 and 57 may also be varied by adjusting the pressure of the wick 23 on the roller 12 and by varying the height of the tank 26. When it is desired to decrease the quantity of liquid imparted to the thread or yarn 34 the roller 57 may be retracted by raising the handle 58 to remove the roller 57 from engagement with the thread PS and the roller 42. The roller 57 will be retained in the retracted position by means of the lever 60. If a still smaller quantity of liquid is to be transferred to the thread or yarn 34 the roller 42 may be removed from engagement with the thread 34 by raising the handle 52. The roller 42 will thereby be removed from driving engagement with the roller 12 and the roller 42 will be retained in a retracted position by the lever 53.

The roller 12 may be rotated in either direction. When this roller is driven so as to,.rotate with the periphery thereof moving in a direction opposite to the movement of the yarn 34 more moisture will be transferred to the thread than when the roller 12 is rotated in a clockwise direction in Fig. 3. It will be further appreciated that any change in the rotating direction of the roller 32 will reverse the rotation of the rollers 42 and 57 to further alter the moisture transferred from these rollers to the longitudinally moving thread or yarn.

While the invention has been described with reference to specific structural details it will be appreciated that changes may be made therein by those skilled in the art. Such modifications may be made without departing from the spirit and scope of the invention as set forth in the appended claims.
