. z claims. (c1. ca -aos) This invention relates to the treatment of yarn with liquids and is particularly useful in the application of mildew inhibitors, dampening solutions, and the like.

In the manufacture of cord for tires, belts and other products it has been found desirable to treat the cord material in the yarnv stage by apspray heads are directed to spray iluid vertically plying liquids thereto. Dimculty heretofore has been encountered in obtaining uniform treatment without using excessive liquid such as to Iwet the surroundings and waste objectionably.

The present invention aims to overcome thev foregoing andy other diillculties'.

The principal objects of the invention are to provide highly uniform wetting of the yarns by continuous treatment. to provide substantially complete saturation, and to provide for regulating the amount of treatment.

A further object is to provide for effectively treating the yarns upon thebeams during the warping process. 4

These and other objects will appear from the accompanying drawings.

Of the drawings:

Fig. 1 is an elevation of apparatus illustrating and embodying the invention.

Fig. 2 is a cross-section thereof taken on line- 2-2 of Fig. l.

In accordance with the invention a. row of spraying mechanisms are constructed in a manmunication with the interior of the pipe. The

against the beam. A flexible hose 32 supplies fluid under pressure from any desired source (not shown)y to one end of the pipe, the other end being closed by a cap' 33. l

A shield 34 In the form of an inverted trough of rectangular cross-section and closed at its ends is supported from the trough I5, as by cross bars 35 A slof, 36 in the top of the shield'extends thjerealong parallel to the axis of the beam and over the spray heads and is adapted to limit the lspread of the spray reaching the face of the beam, the width of theA slot being preferably adjustable, as at 36a. The .shield is shorter than the distance between flanges Illa, I0b of the beam so as to clear them Iandhas brackets 3l, 38 fixed thereto at its opposite sides in which freerunning rollers 39, 40 are journaled in position to contact with the face of the beam or the yarns thereon. A exible drain pipe 4I is provided to drain excess liquid from the trough I5. For best results it is desirable that the spray give a generous delivery within the shield, the surplus being recovered by means of the trough and drain.

The weights 22, 23 are made sufficiently heavy to overbalanoe the trough, spray pipe, and shield,

' so as to cause the rollers 39, 4U to contact with ner to provide a uniform spray across the length of a beam, the spray being directed against the surface of a beam while yarns are being beamed thereon, and the spraying mechanism is maintained at a` constant distance from the yarns during the beaming operation. Provision is made for obtaining a high degree of uniformity in the application of the spray to the yarn.

Referring to the drawings, the numeral ID designates a warp beam supported rotatably in bearings II, I2 of a suitable beaming device (not shown).A adapted to rotate it. The yarns I3 are led to the beam in parallel relation over a guide roller I4. A trough I5 as long as the beam is suspended under the beam by straps I6, I'l passing over pulleys I8, I9 rotatably mounted in pedestals 20, 2l. Weights 22, 23 are suspended from the other ends of the straps. The trough is guided for vertical movement by lugs 2l, 25 slidably tted in'guides 25, 21 xed to the floor 28 below the beam. A pipe 30 is mounted in the trough I5, lengthwise thereof, and a. series of spray heads 3| are mounted on the pipe in .spaced apart relation therealong and in comthe surface of the beam or the yarn thereon at all times to maintain the spray heads at a substantially constant' distance from the material on the beam. The'arrangement is such that as the yarn is beamed a substantially uniform ,spray in the form of a band extending axially of the beam is projected against the yarn'as it is beamed and the spray is applied constantly and uniformly throughout the beaming operation.' Each yarn is given uniform treatment and each convolution of yarn is subjected to successive wettings at successive revolutions by contact with succeeding convolutions being sprayed. The slot 36 may be made adjustable by a slidable shutter 36u-mounted on the shield.

In the operation of the apparatus, a beam I0 is rotatably mounted in its bearings abov'e the sprays, and a plurality of yarns are led over the through the spray where they are uniformly.

treated. In thisaction the liquid reaching the beam is controlled by the opening in the shield 34, and surplus liquid drops from the shield into '55' the trough I5 for recovery.

Y Miniaturv Variations may be made without departing from the scope of the invention as it is defined i by the following claims; I

We claim:

1. Apparatus 1for treating yarn. said apparatus. comprising a .beam rotatable about` ahoriz'ontal yarns, spray means for continuously applyinga spray of liquid to the yarn as itl is beamed, said spray` meansl comprising a plurality of spray heads located below the beam directed at the axis ior simultaneously beaming a plurality o f lower face of said beam in closely'spaced-apartrelation to provide a substantially uniform upwardly directed spray across the face ofthe beam. anadjustable shield between said spray heads and said beam for restricting thespread ofthe' spray, means below said shield andi-said spray heads for recovering the excess sprayed liquid,"

spacing means including rollers bearing 'against the lower face of the 'yarn on the beam, and means for urging and guiding saidrollers, said shield, and said spray heads as a unit toward the face of the beam for maintaining said spray heads at constant distance from the yarn on the beam. 2. Apparatus for treating yarns. said apparatus comprising a rotatable beam for beaming yarn thereon, spray means extendingk along and below* the face of the beam for applying a spray ot i Y u 4 e liquid to the yarn as it is beamed, said ma! means comprising a row oi spray heads. a slotted shield'for conilning the Spray from said heads. means for adjusting the width of the slot in said shield.- means ior moving the said spray means toward and away from said beam, and mean; (or maintaining the spray heads at a unifonnvdistance from the yarn on said beam.v
