Definitions

  • the invention relates to a twisted strand for domestic and deco-rative articles, more particularly for wickerwork, wickerwork furniture, coal cauldrons, shell-baskets and the like.
  • the twisted strand consists in a core made of vegetable or synthetic fibres and a covering made of natural or synthetic.y material tightly surounding the core and forming a tight surface.
  • the fibres forming the core are, for instance, made of wood shavings, and are twisted or woven together.
  • a guiding thread may be provided centrally in the strand.
  • the strength of the strand as regards pull and twist may be increased by an innery member spun in the core fibres and preferzoifably made of a yarn-like twisted or spun thread,
  • the outer casing, of uniform thickness, of the twisted strand formed by the covering hand may, likewise be reinforced by a multiple, for instance double covering.
  • the two covering bands are twisted in opposite direction to each other.
  • the covering band may further be reinforced by means'of a thread-like strip 39;:,preferably arranged on the inside or between two layers thereof.
  • a further characteristic of the invention resides in that a thread or band-like member may be twisted around the core and beneath the cov- ,ering, prefer-ably opposite to the direction of the bres of the core.
  • a twisted strand made according to the invention in addition. to being very stiif and resistant to pulling, has an increased strength .against kinking and twisting.
  • the new twisted strand is reliably protected against being crushed which frequently happens with reed and cane. Nevertheless the flexibility and smoothness of the twisted strand are not impaired since the resiliency of the fibres of the core is neither influenced by the inner member nor by the covering wound therearound.
  • the new twisted strand further forms a tight 5.. mass which by reason of the outer covering wound therearound, does not loosen unintentionally.
  • Fig. 1 shows a portion of the novel twisted strand (with guiding thread);
  • Fig. 2 shows a portion of twisted strand with the core spun in the interior
  • Fig. 3 shows a'partly covered portion of twisted ll' strand with a thread wound therearound between core and cover;
  • Fig. 4 shows a portion of twisted strand with a double covering
  • Fig. .5 shows the inner side of ⁇ a piece of cov. ering band in plan.
  • the new twisted strand comprises a core a and a covering b.
  • the core may be made of vegetable or synthetic iibres. It is preferably made of wood shavings, cane fibres, reed or the like.
  • the covering b preferably consists of a band d wound tightly around the core a.
  • the convolutions of the band d partly overlap so thatva uniform, tight and smooth surface is formedwhich completely covers the core a even at the sharpest bends,
  • the band d is preferably wound around the core a in such a manner that its sense of rotation is opposite to that of the core fibres.
  • the covering band d consists of flexible, waterproof material capable of resistance.
  • Synthetic bands for instance made of sheet cellulose, more particularly so-called glass skin as well as suitably treated bands made of vegetable fibres such as impregnated bast or bands made of impregnated fabric may be used.
  • the core receives a good support and a secure guide. Its flexibility and strength are simultaneously increased.
  • a guiding thread e made of animal, vegetable or synthetic fibres may be arranged in the centre of the core a.
  • a threadorband-like centre member may be employed. It is preferable, however, to embody in the twisted fibres of the core, a thin drill or spun yarn f. The sense of rotation thereof is opposite to that of the fibres of the core.
  • a threador band-like twisted covering member g tightly surrounding the core a and preferably running opposite to the sense of rotation of the fibres of the core.
  • This twisted covering member g which further increases the strength of the strand and likewise protects it from being crushed, also prevents the dense mass of the core from becoming loose. In consequence of its helicoidal arrangement the twisted covering member g may follow the movements of the strand. It thus does not impair the flexibility thereof.
  • band d is in this case arranged opposite to the direction of rotation of the twisted covering member Vg.
  • a double covering mj may be provided in twisted strands, the surfaces of which have to be particularly resistant. This is preferably arranged in such a manner that the two covering bands h and i are wound around the core in opposite directions.
  • the covering is further increased by thread-like strips k mounted for instance on the 35-.iinside of the covering band or embodied therein between two layers.
  • the reinforcing strip lc may be made of Vegetable, animal or synthetic fibres; a thin cotton thread is preferably used.
  • two or more strands of the kind described may be woven or twisted together.
  • the resistance of the strand may be increased still further by treating, for instance, impregnating it, with an adhesive.
  • a gelatineor glue-containing liquid may, for 501;"finstance, be used as adhesive.
  • the strand may also be treated with an impregnating medium. Paraflin, oils, fats, varnishes or lacquers, for instance, natural and synthetic resin lacquers ,may, for instance, be used.
  • TheV treatment with "these media may be effected in such a manner that the constituent parts are saturated therewith prior to or during the manufacture, ory the finished core is saturated.
  • novel strand may be produced in any desired color by using, instead of the translucent covering band, a colored or lacquered band. In this manner strands may be produced for decorative purposes in the brightest colors without it being necessary to lacquer them after their manufacture is completed.
  • the core may be formed only of a single thread, for instance of a wood splint or spill which is tightly twisted to such an extent that the core l0 receives a strong structure.
  • the new twisted strand is particularly suitable for wickerwork, wickerwork furniture and the like. But it may also be employed for packing, as lining and covering, as' fences (railings), as 15 heat protective means, for footwear (small sandals, shoes) as festoons and decorations and so on.
  • a twisted strand for woven articles such as wickerwork furniture, baskets, carriage bodies, and the like, comprising a core of at least one strand of wood shavings, and a covering band wound around the core and composed of a flexible and waterproof cellulose sheet.
  • a strand according to claim 1 in which a guiding thread is provided centrally of the core.
  • a strand according to claim 1 in which a guiding thread is provided centrally of the core,
  • a strand according to claim l in which the covering band is provided with thread-like reinforcing strips.
  • a strand according to claim l in which the covering band is provided with thread-like reinforcing strips of animal fibres.
  • a strand according to claim 1 in which an intermediate covering is provided between the core and covering band in the form of a thread which is Wound around the core in a direction opposite to that of the core.
  • a strand according to claim l in which the strand of wood shavings is woven.
  • a strand according to claim l in which the strand of wood shavings is twisted.
