Abstract: PURPOSE:To reduce contamination of a completed yarn package with oil splash by installing an inclining plate member having such a size as covering a major part of the undersurface of a traversing device for a yarn, allowing oil drops received by the plate member to flow down, end collecting them by an oil drop collecting member. CONSTITUTION:A touch roll 2 and a takeup drum 4 are provided in the lower part of a traverse box 1, and a yarn running from above to below in the attached illustration is traversed by a traverse device 1 and taken up on the drum 4 through the touch roll 2. In this yarn takeup device, an inclining plate 7 is installed under the traverse box 1 in the condition inclined as a whole so that one end on the side in front of the takeup device becomes the lowest, wherein the plate 7 is formed in such a size as blocking the whole surfaces of the box 1 and drum 4 interposing a gap in between which is extending vertically. Oil drops received by this inclining plate 7 is allowed to flow down to the undermost end side to be collected by an oil drop collecting member 16 through a gutter 10.

Abstract: PURPOSE:To provide a bobbin chuck capable of withstanding high speed unpacking of a package, by arranging stepped portions to be engaged with opposite ends of a bobbin to a bobbin chuck and an end body, and gripping the bobbin with resilient O-rings pressed. CONSTITUTION:The bobbin chuck body 13 is rotatably supported on a support shaft 11 through a one side sealed ball bearing 12, and the stepped portions 13b, 14b are provided to the bobbin chuck body 13 and the end body 14 to engage with the opposite ends of the bobbin 5. When it is required to mount the bobbin 5 onto the bobbin chuck body 13, the end body 14 is dismounted from the body 13, and after the bobbin 5 is mounted onto the body 15, a threaded portion 14a of the end body 14 is screwed upon a threaded portion 13a of the body 13. Upon screwing of the end body 13, the O-rings 15, 16 can engage to opposite ends of the bobbin 5 to grip the bobbin 5. Thus if the end body 14 becomes loosened, the gripping force will not be drastically decreased, and therefore the bobbin chuck can withstand high speed unpacking of a package.

Abstract: PROBLEM TO BE SOLVED: To recover both of a paper tube and a remaining yarn for recycling. SOLUTION: A holder 11 and a block body 21 are oppositely arranged to combine a cutter 31, to provide an opening part 21a suitable for the outer diameter of a paper tube PT on a block body 21. The block body 21 inserts the tube PR into the opening parts 21a in an axial direction via the holder 11, to remove a remaining yarn Y on the tube PR so as to extract the yarn Y in the axial direction, and the cutter 31 can cut and align the yarn Y on the tube PT thickly to the minimum thickness.

Abstract: PURPOSE:To provide a method for washing an interlacing nozzle by which the interlacing nozzle can rapidly be washed. CONSTITUTION:Solidified substances (S) deposited on the inner surface of a yarn passage 11 in an interlacing nozzle 10 are washed. In the process, a, pressurized gas is fed into a container 21 while keeping a valve 22 in an opened state and jetting a liquid from the tip of a jetting nozzle 23. Thereby a gas- liquid mixture is obtained and jetted from a gas-liquid jetting port 12 to wash the yarn passage 11.
