In a bobbin holder 1 according to the present invention, flexible rings 3a to 3h each comprising a ring-like spring member 30, a pair of solid rings 38 fixed to both side surfaces of the paring member 30, a pair of solid rings 38 fixed to both side surfaces of the spring member 30 and rubber members 39 disposed on the inner and outer peripheries of the spring member between the solid rings, are loosely fitted between a cylindrical bobbin 23 and a rotary cylinder 2 to which the bobbin is inserted. The solid rings 38 are pressed from both side surfaces of the flexible ring, respectively, and the ring-like spring member 30 undergoes deformation in the direction of an outer diameter so as to increase its diameter. As the rubber members 39 come into close contact with the inner peripheral surface of the bobbin 23, the bobbin can be gripped. In this case, in the bobbin holder described above, the difference .delta. between the outer diameter Ds of the rotary cylinder and the inner diameter Db of the bobbin is not greater than 10 mm and the thickness t at the end portion side of the rotary cylinder may be smaller than the thickness thereof at a portion near the engagement portion of the rotary cylinder with a driving shaft. When such a bobbin holder 1 is assembled into a take-up device for taking up a liner material such as a yarn and a steel wire or a synthetic resin film, a fiber sheet, paper etc, to the bobbin 23, high speed take-up while the bobbin is strongly gripped can be accomplished.
摘要:
An apparatus for treating yarn with fluid designed to provide a yarn, which consists of a multifilament, with coherence by using a working fluid. The apparatus is provided with first and second components which have flat surfaces fixed in parallel against each other with a gap G (mm) provided between them, the first component having at least two fluid conduits which are provided with a specified crossing angle (.theta.) so that they cross each other on the extended lines of their axes and which are opened in the flat surface. The first and second components are fixed to satisfy the requirement in which the gap G between the flat surfaces facing each other is 0.2 mm or more but 5 mm or less, and they eject the working fluid under a specified pressure through at least the two fluid conduits onto the yarn, which runs between the flat surfaces, to provide the yarn with coherence.

This invention relates to a method and apparatus for producing a polyester fiber which cools a plurality of molten polyester fibers from a spinnert 2 to a temperature below a glass transition point, then takes up the fibers by a non-heating first godet roller at a take-up speed less than 4,000 m/min, heat-stretching the fibers between the first godet roller and a non-heating second godet roller 10 inside a normal pressure steam atmosphere (first heat-treating device 8) higher than the glass transition point of the polyester fiber, and heat-treats the fiber by a pressurized steam atmosphere (second heat-treating device 9) higher than 105.degree. C.
摘要:
An apparatus for preparing a nonwoven web in which a bundle of continuous filaments is jetted from a nozzle together with a fluid stream, the filaments and the fluid stream impinge upon a first impinging surface, and after impinging, the filaments and at least a part of the fluid stream are guided to a collecting surface by a second impinging surface.

A suction gun has a first injection nozzle and a second injection nozzle. The first and second injection nozzles inject pressurized water, thereby to draw a yarn with a suction force of the pressurized water. The second injection nozzle has a plurality of jets, respective axes of which intersect with each other at an intersection point. The intersection point is located in a position displaced by E, which is preferably in a range from 0.2 mm to 0.9 mm, from an axis of a through hole which is included in a pressurized liquid exhaust passage.
