  • Patent number: 5120294
    Abstract: A method and apparatus are disclosed for forming a tubular yarn carrier of the type adapted to have a yarn wound thereon to form a yarn package, and which includes an inturned annular end portion which is adapted to support the carrier on an internal spindle of a winding machine. The method of forming the inturned annular end portion includes inwardly turning one end of a tubular body member and so as to cause the end to be inwardly turned about an arc of about 180.degree., and while concurrently guiding the inwardly turned end radially outwardly into contact with the inside wall surface of the tubular member. The method results in the formation of a frusto-conical end portion which essentially locks against the inside wall surface of the carrier and thus prevents the inturned end portion from opening up during use.

  • Patent number: 5067936
    Abstract: A method of manufacturing a yarn carrier designed to accommodate the tail of the yarn to be wound therearound without severing. A tube is wound from paper and a portion severed therefrom, producing a burr. A subsequent grinding operation removes the burr, and forms a beveled region having loose fibers to cushion the yarn against a winding mandrel.

  • Patent number: 5014928
    Abstract: A yarn carrier, and a method and apparatus for manufacturing the same, are disclosed, and wherein the yarn carrier is characterized by the ability to accommodate the tail of the yarn to be wound thereon between the carrier and the base plate of the winding machine, without severing the yarn tail during winding of the package. The yarn carrier includes a tubular body member composed of wound layers of paper and defining parallel inner and outer wall surfaces. The base end portion of the body member includes a generally flat end surface, and an annular surface segment which is positioned adjacent the inside of the flat end surface, and with the annular surface segment comprising loosened paper fibers so as to be relatively soft.
