Definitions

  • This invention is a binder twine comprising a resilient core consisting of continuous filament, twisted or untwisted strands of viscose, polypropylene or nylon or other resilient synthetic filament, and a cover or wrapping consisting of extensible paper, such as kraft paper, twisted about the core.
  • twine Another known type of twine is the combination of kraft paper and fiber glass disclosed in US. Patent No. 2,861,416, issued to American Sisalkraft Corporation on Nov. 25, 1958.
  • Twine utilizing fiber glass may be quite strong but is also relatively stiii and when placed under tension is of limited extensibility. Furthermore such a twine is inclined to be brittle, hard on the hands when hand tying, and not particularly suitable for use in binders. Also use as twine of other synthetic filaments by themselves has been suggested. Various disadvantages such as lack of the bulk required for binders, lack of wet strength, and lack of knot holding ability are attendant upon such use.
  • fiber glass may be used as a core material in a twine and a kraft paper cover wound about it but this type of twine is also stiff and since the extensibility of the core is substantially less than the cover, the fiber .glass core will break at the limit of its extensibility without necessarily breaking the cover thus rendering the twine useless without being visibly so.
  • the present invention provides a twine particularly suitable for use in binders and which can be readily knotted, with conventional machinery; possesses satisfactory stretch, strength and flexibility and otherwise meets the requirements for a satisfactory replacement for sisal binder twine.
  • the twine of this invention consists of two components both of which are extensible and under tension have substantially the same breaking point. Thus when the twine of the present invention is placed under stress the core material and cover material, while having two separate breaking points, have breaking points which are close enough together that they appear to break simultaneously. This characteristic results in good knotting ability.
  • twine of this invention will be found quite water resistant and rodent resistant, a feature of significance when used as binder twine. Also, the twine of this invention has been found to possess an improved weight/ strength ratio and will normally perform much better than equivalent natural fiber twine in this regard as it will have approximately half the weight and three times the tensile strength of the equivalent natural cordage.
  • FIGURE 1 is a plane view schematically showing the preparation of the twine
  • FIGURE 2 is a section through plane 22 of FIG- URE 1.
  • the twine of the present invention is made with a core consisting of continuous filament, twisted or untwisted strands of any of viscose, polypropylene or nylon, and a cover consisting of extensible paper such as kraft twisted about the core. If untwisted filaments are employed they usually become twisted when the cover is wrapped about the core. Depending upon requirements, normal or wet strength paper may be used.
  • suitable paper such as kraft paper sold under the name Clupack is cut in long strips of a suitable width depending upon the diameter of the core material.
  • Clupack is a kraft paper which has been microscopically crimped across its direction of run in order to make it extensible in one direction.
  • the purpose of impregnating the paper in this manner is to make it sufficiently pliable for twisting and also depending upon the contents of the bath, the paper so impregnated will affect the stiffness or softness of the twine produced and thus this characteristic can be controlled to some extent.
  • the strip of kraft paper After being passed through the bath the strip of kraft paper is twisted about the core material by means of a standard ring or cube twister and the resulting twine is wound on a twister spool and permitted to dry after which it can be used in any binder or in other forms of wrapping and tying machines.
  • a twine comprising a core of extensible synthetic plastic filaments and an extensible paper cover wound about said core.
  • a twine comprising a core of extensible polypropylene filaments and an extensible kraft paper cover wound about said core.
  • a twine comprising a core of extensible viscose filaments and an extensible kraft paper cover wound about said core.
  • a twine comprising a core of extensible nylon filaments and an extensible kraft paper cover wound about said core.
