Abstract: 312,590. Seeley, A. Feb. 25, 1928. Winding-machines; moistening.-In a method of coating or treating yarn, thread, cord, or wire with solid or liquid substances during winding on to or into bobbins, skeins or other forms, the yarn &c. is passed between coaxially mounted discs which are made to dip into, or are charged or supplied with the substance to be applied. The discs may be revolved by'driving means, either in or against the direction of travel of the yarn, and may also be traversed laterally or moved in any direction in order to guide the yarn and cause it to be wound into any desired form. Troughs. boxes or other vessels containing the applied substance may be moved relatively to or with the discs to supply the latter with the substance. Discs of flannel or other fabric may be provided between the discs. In the machine shown in Figs. 1 and 2. yarn is unwound from swifts a and wound on bobbins b mounted in the usual way on spindles c. The bobbins are revolved by means of wheels f engaging friction collars e on the bobbins. Motion is transmitted from a stepped pulley g by means of a shaft and bevel gears to shafts k on which the wheels f are mounted. From one of the shafts k motion is transmitted by a chain m to worm gearing p, q, by means of which a cam s is rotated. The latter is arranged to cause a shaft y to be oscillated, and arms 1 secured to the shaft y cause rails 3 to be reciprocated, these rails carrying adjustable yarn guides 7. Liquid is applied to the yarn by pairs of discs 8 arranged to dip into liquid in troughs 9 supported on rails 10. The discs are secured in pairs to shafts 12 driven by belts from the shafts k. The discs of each pair are fixed at such a distance apart that the yarn is drawn between them with sufficient friction to ensure that it shall be charged with liquid. The yarn passes over guide rails 14 mounted in adjustable brackets 15, so that its degree of contact with the discs may be varied. In the apparatus shown in Fig. 4, discs 8, dipping into liquid in a trough 16, are mounted on a shaft 17 which is moved lengthwise by means of an arm 19 actuated by a cam. The discs thus serve to guide the yarn on to the bobbin b. The trough 16 is also moved lengthwise by means of an arm 22 fixed to the shaft y. The discs shown in Fig. 5 have concentrically grooved opposing faces, and are mounted loosely upon the shaft, but prevented from moving along it by adjustable collars 27. The discs may be provided with leather covered faces 29, Fig. 6. Fig. 7 shows a pair of discs with a disc 44 of flannel or other fabric between them; two fabric discs may be provided. The troughs containing the material to be applied may be heated or cooled. The discs may be supplied with liquid or solid materials in a jet or jets. or by contact with the discs. Examples of the substances applied are size, oil, wax, varnish, starch, alkali solution, acid solution, colouring matter and French chalk.
