Definitions

  • the invention relates to a rotationally symmetrical body, which has a flat Packaging is surrounded.
  • Flat packaging in the context of the invention is understood to mean flat structures such as Foils, fabrics, nets and the like, which, as packaging, completely or partially the packaged body surround or envelop and lie more or less firmly on it.
  • the flat packaging can be closed or sealed as with foils; the slides can but also have perforations over their entire surface or in some areas.
  • rotationally symmetrical bodies are to be understood as bodies which have a rotationally symmetrical shape, e.g. cylindrical, conical, dumbbell-shaped exhibit.
  • the rotationally symmetrical body can also have mixed shapes, e.g. at the Be conical at the beginning, cylindrical in the middle and conical again at the end.
  • the invention particularly relates to packaged rotationally symmetrical bodies such as Yarn packaging, with or without sleeves, yarn spools, in particular dye spools and the like.
  • the packaging is e.g. in U.S. Patent 5,358,771.
  • the packaging consists of a perforated film, each of which has openings at the front of the packaging have for the sleeve.
  • CA 2 092 967 A1 describes packaged packaging in which the Foil perforated on the jacket side, however, is not perforated on the end faces.
  • the film is made of a sharp object, for example a cutting blade or a knife cut open and removed; also the Often, transparencies are manually torn open by the operator by trying on something tear the film in one place and tear it open completely.
  • a sharp object for example a cutting blade or a knife cut open and removed; also the Often, transparencies are manually torn open by the operator by trying on something tear the film in one place and tear it open completely.
  • flat packaging e.g. Tissue.
  • the object of the invention is therefore to provide a packaged rotationally symmetrical body To provide, in which the packaging can be easily and easily removed without there is a risk that the packaged goods will be damaged or even destroyed.
  • Task of The invention furthermore provides a packaged, rotationally symmetrical body, in which during the tearing the tearing substantially along a straight line and can be done without interruption.
  • This object is achieved by packaging in a flat packaging rotationally symmetrical body, the packaging of which to remove the packaging serving linear part of the packaging with a higher linear compared to its environment Has tear strength in the form of a tear strip or tear thread, and its packaging a woven, knitted, mesh or in particular consists of a film.
  • the tear strip or tear thread is advantageously along the surface line of the packaging attached, but can also be attached along the circumference or in another direction.
  • the tear thread is preferably sewn into the packaging.
  • the tear strip consists of a welded strip that has a higher tear resistance than the packaging.
  • the strip is preferably thicker than the thickness of the Packaging.
  • the strip can also be made from a tape attached to the inside or outside of the packaging exist, the attachment of the tape can e.g. caused by gluing.
  • the band it can be a woven fabric, a knitted fabric or a film.
  • the flat packaging can be a film, a fabric, a knitwear or a net.
  • the Foil can be completely or partially perforated.
  • the packaging advantageously consists of a film which perforates on the jacket side, is not perforated on the end faces.
  • the bodies, especially the packaging of Yarns can be arranged as a stack or in the form of columns.
  • the Yarn packaging a cylindrical shape.
  • Yarn packages are packages for yarns, threads or similar line-shaped textiles Structures that e.g. Can be present as a bobbin, that is, yarns that are applied to a sleeve.
  • the packaging can also be designed without a sleeve.
  • Forms of packaging which are packaged according to the invention and with a tear strip or Tear thread can be provided, e.g. in the older German standard DIN 61800 or in of DIN ISO 5238.
  • the presentations are preferably cylindrical and flat End faces on; however, they can also be conical or shaped in some other way.
  • the flat packaging in particular in the form of a film, and also the tear strips or Tear-off threads can consist of conventional synthetic polymer materials.
  • Suitable Polymer materials are all film and thread-forming polymer materials such as polyolefins, in particular polypropylene and polyethylene, polyesters such as polyethylene terephthalate or else modified polyethylene terephthalates. Polypropylene and polyester are preferred.
  • the packaging and the tear strips or tear threads can be made of the same material consist. However, different materials can be used.
  • the tear strip or tear thread can be attached to the packaging in various ways get connected.
  • the tensile strength of the sewn thread or yarn should, however, be higher than that Tear strength of the flat packaging along the seam.
  • the seam runs essentially longitudinally a generatrix of the packaged goods.
  • the stitches of the seam Packaging especially the film along the seam also weakened, making the thread very light can be subtracted along the entire tear line. It is useful if the Tear thread protrudes a little at the beginning or at the end of the outer surface, so that the Can take the thread better and then tear it in one go according to the tear line can.
  • the tear thread can also be applied directly to the packaging, i.e. on the outer surface of the Packaging, e.g. by gluing. It is also an attachment of the thread possible within the packaging.
  • the flat packaging is in the form of foils on the packaging machine in two submitted separate webs, wherein one of the films has a constant length, for example about a quarter of the circumferential length of the bobbin to be packed and a sewn-in thread and the other film covers the remaining part of the circumference.
  • the two Foil webs are then connected to each other at two welds. This way and This creates a flat packaging that has a welded-in strip with tear thread contains.
  • the packaging in the form of a film has a typical thickness for packaging films, it lies usually between 10 and 50 ⁇ m; this thickness can, provided that it meets the requirements profile of the subsequent treatments allows, also be exceeded or fallen short of.
  • Dye packages are preferred for dye packages.
  • the tear strip or tear thread can be arranged so that the tear line from above down, i.e. along the axis of the body, e.g. a neck runs.
  • Packaging such as a film to tear from top to bottom, both along one perforated as well as a non-perforated part, if there is one.
  • Tear strips or tear threads of the individual presentation to each other at their ends connect so that the entire stack or columns can be torn open in one operation can happen, that is, the tear thread or tear strip over the entire stack or the entire column can be separated from top to bottom by a single tear.
  • the packaging in the form of a film can be pulled over the packaging as a tubular film and then shrinked so that it fits tightly on the packaging.
  • the tear strip or tear thread can already be applied to the Put up to be present; the tear threads or tear strips can also still be attached when the film is already drawn over the packaging.
  • the advantage is further that the packaging is immediately e.g. after winding it up, e.g. on a texturing machine.
  • the packed coils can then be as they are Dyeing process are fed, processed and sent to the consumer, i.e. Weber, knitter and the like. Only then can the packaging be removed.
  • the packaging may also be perforated in zones.
  • the invention is illustrated by an illustration which schematically represents a packaging film explained.
  • 1 means non-perforated film edges, which essentially cover Serve end faces of the body
  • 2 is the perforated part, which in the packaged body Shell surface forms
  • 3 is a sewn thread that is used to remove the packaging on the packaged Bodies can be torn from top to bottom or vice versa in one go.
