,Application niednovember en, 1925*.ser'iai Ne. raam-5 4 f 1- In; ,the winding; of yarn, packages, more particularly inthe form of yarnV cheeses,

which are cross wound and thereforeof a soft naturein the compact wound form, a

central tube or holder is provided on which theyarn is wound. Vhen'it Ais desired to Vdye such'a cheese in the wound form, by the vpassing of such fluids through the yarn mass, it has been hitherto necessary to remove such central tube, and afterwards replacev it or insert in the central bore which it occupieda holder vof some other stiff inaterial. The weight'and cost ofthetube or other holder adds considerably to the cost of the 4yarn in handling and shipment, with the addition of the cost of shipment of thetubes or holders back tothe source, when the cheeses have been wound off by the purf chaser. The percentageof1 waste of these tubes or holders is also high. l

rlhe function of these tubes whenreim sertedfin cheeses is to preventfthecheese bore vfrom closing` with kresultant stabbing of they inner coils ofthe windings whenA the cheese is placedon a. spindle for windingv 013, My present invention has for .object a ineans for keeping the boreofa cheese open to prevent possible Ydamage to the inner yarn windings without the use of stiff tubes lor the like', with a minimum of cost, the weight. added to each cheese being inlinitesimal-` According to the said invention I provide al perfectlyflexible tube-which may be placed upon .a spindle andr thecheese Wound there-` upon, `or theftube vmay be inserted in 'tlie cheese bore at any pointinthe treatment of the said cheese, if the latter hasv been wound upon a stiffl tube or the like, after the re` 1 moval of the latter. The cheeses may there` fore be packed closeflyyforV shipment, some compression of the saidcheeses-being permissible, and the presencev of the flexible holder in the boreof each ensures that at any timegeach cheese-may be placed upon a spindlefor winding off or any'other treatment without danger of such 'spindle becoi'ning entangledfwith the inner yarn `windings,

"thus stabbing andspoiling the cheese.,

The accompanying drawingsy sufficiently Aindicate an embodiment. of my invention.
