Definitions

  • Thread wound on a thread winding tube is released generally or customarily from the outermost winding layer of the wound thread, which necessitates the turn or rotation of the thread winding tube together inevitably with the thread to thereby cause the thread to have resistance to the rotation and be occasionally damaged or cut. Moreover, it is difficult to take out the thread at high speeds by this method of releasing.
  • the winding core or tube is to be removed while being cut by use of scissors or the like, which work is quite difficult and troublesome. And the cutting tools such as scissors possibly cut or damage the thread.
  • the desire in this field of art is such a thread winding core or tube that behaves as usual in winding thread thereon and can be readily or simply removed, after winding thread, for releasing the thread.
  • Thread referred to in the present invention may include general threads, strings, cords and the like, which are flexible and thin and can be drawn out from the inner side when wound.
  • the reason for the spiral formation of the tubular body is an easy cutting operation, particularly, from the ends of the tubular body. Angles of the spiral may be freely selected. In case that the angles of the spiral are large with respect to the longitudinal axis of the tubular body, the cutting is easy but the cutting distances become longer. And to the contrary when the spiral angles are smaller. 40° - 80° were empirically preferable and 50° - 70° most preferable. Complete or nearly spiral formation may be adoptable.
  • a paper tube fabricated by partially overlapping two or multiple material tapes may be subjected to the same machining as for the foregoing single layer structure.
  • the spiral angles in or for the easy-cut machining are not limited by the feeding angles of material tapes for fabrication of the paper tube.
  • the thread winding tube according to the present invention may be provided on the outer surface with embossing, grooving or application of particles, for enabling an object to be wound to have ridges and grooves on the surface. Moreover, the thread winding tube may be applied on the outer surface with a thin film for protecting or other purposes which film may be removed after removal of the thread winding tube for releasing thread.
  • Fig. 1 is a perspective view showing an example of a thread winding tube according to the present invention.
  • Fig. 2 are sectional views of the perforation in Fig. 1.
  • Fig. 7 is a schematically explanatory plan view of a manufacturing method of a double-layered paper tube according to the present invention.
  • Fig. 9 is a perspective view showing the thread winding tube provided with the easy-cut machining being cut and removed from the inner side.
  • Fig. 6 is a plan view of the easy-cut parts shown straightly, which merely illustrates the shapes of the cuts.
  • the easy--cut parts may comprise the mere apertures, or the consecutively provided shallow cuts together with the intermittently formed apertures.
  • the feature of Fig. 6(a) having the triangular cuts prevents deviation of a cutting line when cutting is carried out from the left side.
  • Fig. 6(b) shows the simple triangular cuts, and Fig. 6(c) the shape of cuts allowing the effect of the feature of Fig. 6(a) to be enhanced.
  • Fig. 9 is an explanatory view showing the thread winding tube with the easy-cut part being cut and removed from the inner side, in which the winding tube can be removed without influencing the thread wound on the winding tube.
