DEVICE FOR AUTOMATICALLY COATING YARN ELEMENTS FROM WHICH A LAMINATED COHESIVE INTERWOUND FABRIC IS CONSTRUCTED. I

To all whom i1 may con ern Be it known that l; LAWRENCE A. Somme, a citizen of the United States. and resident of East (.leveland, in the county of (javahoga and State of Ohio, have invented certain new and useful improvements in Devices for Automatically Coating Yarn Elements from \Yhich a Laminated (.lohesive Interwound Fabric is (."onstructed, of which I hereby declare the following to be a full. clear. and exact description, such as will enable others-skilled in the art to which it appertains to make and use the same.

This invention comprises an improvement upon the coating device of the ma chine described in my previous application for Letters Patent bearing Ser. No. (368,625 tiled December 30, 1911.. for-an automatically acting maehine for laminated.cohesiveinterwound band in which the band elements are coated under the influence of vacuum and heat and is also an im 'irovement upon the automatically acting device "For coating the jarn elements from which a laminated-cohesive interwound fibrous band is constructed, described in my application for Letters Patent hearing Ser. No. (378,696. tiled February 17, 1912, in which stationar guiding means are employed acting! to hold the hand elements apart while being coated. ln both cases the band elements are stored upon reels which rotate in opposite directions. are wound about a stationary mandrel, are passed through a coating" device and finall) the completed hand is pulled from the man drel and compressed and dried under the action of vacuum and heat.

In the machine hereinafter described the several rotating reels have attached thereto concentrie conical guide memhers which hold the several series of yarn elements and guide them in channels and-wind them upon the mandrel in their exact relative positions. and also serve to hold apart the yarn elements while the coating material is applied thereto. The coating: chamber is separate and spaced "from the vacuum chamber. thus allowing the yarn elements to he coated in the air. thereby gaining a smooth uni'li'orm coating, free from bubbles. which are Specification of Letters Fatent.

quickly formed when the yarn elements are coated in a vacuum chamber since the solvents are then quickly evaporated from the coating material.

'lurther object is to apply the coating: material preferably without pressure. to maintain it in asullieiently liuid state to permit ol the movement of the several series of yarn elements therethrough without distortine them or without distortion of the yarns forming the elements. and to form a smooth outer coating on the band while still on the mandrel.

A. further object is to wind the coated varn elements upon the mandrel under as slight a tension as practicable so asto re duce the strain on the hand in pulling it oil the mandrel since the greater the sion the harder the 'band is pressed against the pullingrolls thereby forcing out a cor-. responding greater amount of the, coating: material Further by winding the series ol varn elements upon the iandrel without thereafter passing: over an. enlarged expanding portion a large amount ()l friction of the yarn ele from theinterior of the band] mcnts one upon the other is eliminated and no opportunity is allowed for individual arns to become distorted from their positions in their respective elements. i

i also employ an open coating chamber spaced from the vacuum chamber into which and over the rotating yarn elements the fluid rubber lows either by gravity or by piessure and from which it is with drawn as ouicltlv as desired.

The invention also includes resilient closin means for the several apertures in the Zcoatinfi and vacuum chambers. and means prior application dll tlllil. tiled Feb. 2. 191%,.

Many portions of the machine previously shown and described in my former applicationreferred to, such as the pulling and flattening devices and band shaping devices are not shown again in this application since it is not necessary to do more than to refer to them .her'ein. sincethey have been previously claimed.

In these views B is a stationary mandrel. B, B, B and BKare reels rotatable in al-; ternately opposite directions thereabout.

C, C are rods secured to these reels and extending radially inward and provided with guide rolls C, Q) for the bands of parallel yarns F, F which compose the fabric band and are herein designated as yarn elements. Tension is supplied by tension rollers C and P and Springs 1 for the yarn elements as they are pulled off from. the

spools C, (l. The inner ends of the rod C are provided with terminal guide rollers (.l, (3. Alternate reels rotate in opposite directions and the rods from each reel, shown as four in number, are secured at their lower ends to a ring F upon a frame F shown in Figs. 1 and 2. T be four guide rods are secured to and equally spaced about this frame and the rollers C pass the yarn elements F inside the ring F which forms the base of the frame F. At the outer end of, this frame is shown a second ring F which is tightly sleeved over the reduced portion F of the guide ring F This guide ring is provided with four guide channels F, F on its outer face through which the yarn elementspass but they do not pass directly therefrom to the mandrel B since the distance passed'over before winding them is too great to insure the accurate application'of the yarn elements thereto. For this reason 1 series of rings F F are protided gradually nearing the surface of the mandrel so that the yarn elements wit! be accurately spaced apart and kept out of contact with each other.

The rings F are provided with channels F, F alternately situated on the outer and inner sides of the rings so as to bind the yarn elements and prevent them from slipping or d'awing sidewise out of proper alinement and yet permitting them to be pulled freely off from the reels.

- In Figs. 1 and 3 the last one F of the series of channeled rings is reduced in diameter and is brought as close as possible to the mandrel so that the yarn elements can be applied thereto at as acute an angle with the axis of the mandrel as may be desired, and the yarn elements are bound. underneath in the channels F R therein, in close proximity to the mandrel so that perfect'accuracy'in winding can be obtained without slipping, also the length of the yarn elements exposed between the channeled guide and the surface of theniandrel is much reduced thereby.

Fig.3 is a perspective view of the outer-. most series of rings which are connected together into a frame by means of longitudinal bars F F The inner and larger ring is flattened and provided with transverse slots F F" and the bearing guide ring'F, is provided with corresponding pins F, F or other means of attachment so that the parts can be detachably secured together and others substituted therefor if required. In this manner the guides are brought as near to the surface of the mandrel as the angle of winding will permit and are spaced apart at a. predetermined distance. The several frames and guide rings attached thereto are so ,proportioned and fitted together as to sleeve over each other, space being left between them for packing rings F, F of felt or other soft material and are inserted in nest form into an opening F in one end of a coating chamber F which-opening they with the packing rings completely fill and prevent the. escape of rubber therefrom. The yarn elements fill the guide channels F and the rubber cannot escape. The rubber preferably falls by gravity through av funnel shaped spout F upon the rotating guides and yarn elements and they are completely coated before winding them on the mandrel.

The rubber or other adhesive material runs out of the outlet opening F and the depth' of rubber maintained in the receptacle can be controlled at pleasure in any-"desired manner. The mandrel projects through an opening F" in the opposite wall of the receptacle and through an opening F in the wall F of the inclosed vacuum and heat chamber G. These openings are preferably spaced apart so as to prevent any possible action of the vacuum upon the rubber in the guide elements therein.

, grates will tc-ml receptacle. The openings i l are protected by resilient gates formal of sliding sections F F controlled by one or more springs F. These gates will make clo e contact with the fabric band as it passes out over the mandrel but will prevent the rubber from oozing out and will. yield sullicie ill; to permit a knot or collected mass of rubber to pass. The resilient action of tl'iesc to smooth and equalize in thickness the exterior coating of rubber upon the fabric band.

in Fig. 5 is shown a central passage l and oblique passages F F in the nnindrel through which the rubber can be injected into the interior of the fabric band before being; coll: psed to thoroughly coat the yarn. An annular groove F communicating with these passages distrih utes the rubber evenly around the exterior I of the mandrel.
