Definitions

  • the present invention relates to the packaging of bales and similar packages, and more particularly to strapping devices for strapping such packages. Still more particularly, the present invention relates to a strapping band.
  • Strapping bands of synthetic plastic material are known and are manufactured by extrusion, either in form of foils from which straps of the desired width are severed, or else they are extruded in form of strips or hands having already the desired width. Because these straps must be applied with manually or poweroperated strapping equipment, and because such equipment is designed to accept straps of a predetermined width, it is necessary that the straps always have the required width because they cannot otherwise be utilized with the equipment.
  • Plastic strapping bands heretofore known are smoothsurfaced and a constant problem with such bands has been the displacement which takes place, for instance as a result of shaking of the bale or package during transport, or for other reasons, which sometimes even ends in slipping-off of the strapping band from the package.
  • the reason for this is, of course, that the smooth surfaces of the strapping band do not provide adequate frictional resistance against such shifting.
  • the present invention provides an elongated strapping band of synthetic plastic material which is not subject to the aforementioned disadvantages.
  • the strapping band or strapping device according to the present invention is no more complicated to manufacture, and is therefore no more expensive than conventional plastic strapping bands, but provides all of the desirable advantages outlined above.
  • a strapping device particularly for strapping bales and similar packages, which comprises an elongated band of synthetic plastic material.
  • the band includes two transversely spaced longitudinal edge portions and has in transverse cross section an undulatory configuration. It is provided with at least one strip-shaped weakened portion which extends intermediate the edge portions in substantial parallelism therewith so that the band can be severed along the weakened portion without requiring the provision of special equipment for this purpose.
  • FIG. -1 is a somewhat schematic cross section through a band incorporating my invention
  • FIG. 2 is a fragmentary view showing opposite ends of my novel band overlapped ready for being secured together;
  • FIG. 3 is a section taken on the line IIIIII of FIG. 2;
  • FIG. 4 is a view similar to that of FIG. 2, but showing the overlapping end portions of the band secured together.
  • my novel strapping band 1 which must of course be understood to be of elongated strip-shaped confiuration, is of undulatory configuration, as seen in cross sectional view.
  • it is provided on both sides with a plurality of longitudinally extending ridges 2 which alternate with grooves between them.
  • Each of the ridges on one side is backed by a complementary groove 2a on the opposite side of the band.
  • weakened portion 2b which, in the embodiment illustrated in FIG. 1, is a depression extending along the crest of one of the ridges 2. This makes it possible to sever the band 1 along the weakened portion 2b without requiring special equipment for this purpose. 'It is evident, of course, that I can provide two or more such weakened portions, depending on the width of the band 1, and on how many narrower sections it is desired to obtain by severing the band 1.
  • FIG. 2 shows the two opposite edge portions 1a and 1b of my novel strapping band overlapped, preparatory to being secured together.
  • the zone in which they overlap is indicated with reference numeral 3 and it will be clear that the securing is effected in this zone, for instance by welding, by means of adhesive, by crimping, by a mechanical connector, or in any well known manner.
  • FIG. 3 which is a section taken on the line III--III of FIG. 2, shows how the grooves and ridges of the end portion 1a interlock with the grooves and ridges of the end portion 1b, thus preventing lateral displacement of the end portions 1a and 1b with reference to one another, as has been found undesirable in strapping bands according to the prior art.
  • FIG. 4 finally, shows the overlapped end portions 1a and 1b, similar to the showing in FIG. 2.
  • FIG. 4 shows a mechanical crimp-connector 4 applied in the region of the overlapped zone 3.
  • This connector 4 is provided with crimp tongues or projections 5 which are pressed inwardly against the material of the end portions 1a and 1b in the well known manner which need not be further described.
  • This can be effected in a variety of ways well known in the art, and can be either in transverse direction of the strip, in longitudinal direction of the strip, or both directions if desired.
  • Such configuration may be undulate in general, it may be zig-zag, or the like.
  • the band is formed with the weakened portion or portions 2b as it is being extruded from this outlet.
  • the height of the outlet of the extruding die that is the spacing between the crests of oppositely directed ridges, is greater than the spacing which is desired in the final band.
  • the strip-shaped blank which is obtained on extruding the synthetic plastic material from this die is subjected to a first longitudinal stretching operation whereby to obtain a preorientation of the macromolecular structure.
  • the blank is cooled or permitted to cool to room temperature, reheated and again stretched or drawn, cooled, reheated and again stretched, and then cooled.
  • This cooling is not of the entire band at the same time, but rather is effected zone by zone, that is in increments, and during this time the band is maintained in stretched condition.
  • the band is again heated and again cooled to stabilize its molecular structure.
  • Thermoplastics for instance polyethylene, polyisobutylene are the plastic materials suitable for the novel strapping band.
  • a strapping device for strapping bales and similar packages comprising an elongated synthetic plastic band of zig-zag shaped transverse cross-section and including two transversely spaced longitudinal edge portions, said band being provided with at least one strip-shaped Weakened portion extending intermediate said edge portions in substantial parallelism therewith whereby to facilitate severing of the band alon gsaid weakened portion.
  • each of said surfaces is provided with a plurality of longitudinally extending ridges and grooves alternating in transverse direction of the band, each ridge on one surface being backed by a complementary groove on the other surface, and each ridge on said other surface being backed by a complementary groove on said one surface, and wherein the bottom of the said grooves is a curved line.
