Definitions

  • the invention relates to a round sling or endless sling of the type previously described in the preamble of claim 1 and known from DE-B No. 2129837.
  • the core only fills the cross-section of the protective tube to about 50-70% and is therefore freely longitudinally movable in relation to the protective tube and that the individual windings of the core are also not fixed in relation to the protective tube and to one another. It is only in this way that it is possible for the different windings to move in relation to one another under a load attack and to have the same length as a result of the load, so that overloading of a single thread winding is avoided.
  • a feature of such a round sling also consists in the fact that in the unloaded state the protective tube is somewhat longer than the core, so that the protective tube lies in slight folds along the core.
  • the prefabricated protective tube is placed on a tube that is open on one side in the longitudinal direction over a circumferential area of approximately 180 °, i.e. pushed onto a gutter and pushed or compressed in the longitudinal direction to less than half of its length so that the tube surrounds the tube with a strong fold.
  • a thread of textile yarn, plastic or the like is drawn in the longitudinal direction through the tube interior or through the interior of the protective tube.
  • the end of the thread drawn through is then drawn back on the outside of the protective tube back to the insertion end and again drawn through the protective tube or the groove in the longitudinal direction. This process is repeated many times in such a way that a thread roll consisting of many layers of thread circles, but formed from only one thread, is created.
  • the protective tube is pushed from the groove in the longitudinal direction onto the thread winding or threads.
  • the thread wrap is then removed from the trough so that it is also free.
  • the compressed protective tube is then pushed over the entire circumference of the thread winding. Its ends are inserted into each other and preferably sewn together.
  • the protective tube has an initial length such that, in the final state, it is still somewhat longer than the thread wrap or the threads around it. As a result, he surrounds the thread winding (s) with a light drapery.
  • the invention is based on the object of designing a round sling of the type mentioned at the outset in such a way that the very flat cross-sectional shape which arises under load, in particular in the system areas, is as far as possible predetermined by the construction of the round sling, or that such a flat cross-sectional shape is also taken even before a load attack, in particular under load, if possible, is already stimulated by design.
  • This object is achieved by the characterizing part of claim 1 and is given an additional support effect by the characterizing part of claim 2.
  • the flat webs could theoretically also be formed by sewing two strips lying one on top of the other in the edge regions to form a tube.
  • the flat webs can advantageously be easily incorporated when the protective tube is being woven.
  • a tube is a two-layer weave, the two layers of which are not connected to one another.
  • known two-ply webbing straps are produced, which differ from woven hoses only in that their two ply layers are connected to one another by a binding chain incorporated during weaving.
  • Such two-ply webbing straps can also be used according to the invention.
  • said flat web or flats are formed by incorporating or running in a binding chain in the desired flat web regions when weaving the protective tube. The chain-free areas of the two-layer fabric then form the actual hose.
  • the flat webs also have the effect of a wear protection strip on both sides.
  • the further invention relates to a sling formed from such a round sling.
  • Stropp is used to denote round slings in which two round sling parts lying opposite one another are combined or connected to one another in an intermediate region between two hanging eyes.
  • the further invention now consists in the mutual connection of the two round sling parts by sewing their opposing flat webs to one another. This ensures that the sewing needle used to produce the connecting seam does not pierce the thread winding and can damage its individual threads. This also ensures that the free movement of the individual threads relative to the protective tube and relative to one another, which is so important for the functionality of the round sling or the sling, is not impaired by the seam.
  • the inventive design of the sling enables the application of an abrasion protection pad - also called a work surface - also without damaging the load-bearing thread winding or without impairing the round loop or thread winding function according to the characterizing part of claim 5.
  • the invention makes it possible, in accordance with the characterizing part of claim 6, to securely fasten protective tubes for the hanging eyes of the slings in a simple manner.
  • the round sling designated overall by 1, consists of a core 2 in the form of one or more thread windings and a seamlessly woven protective tube 3 surrounding the core 2 in its entirety with considerable slack. At least one flat web 4 protruding laterally from its cross section is attached to the protective tube 3 woven.
  • the thread winding of the core 2 consists of monofilament plastic threads drawn endlessly into the tube 3.
  • the flat web 4 is formed during the tube weaving process simply by incorporating a binding chain over its width 5 into the two-layer fabric, as is familiar to every weaving specialist.
  • the round sling 1 shown in FIG. 2 has an woven flat web 4 or 6 on two diagonally opposite sides of the hose cross section.
  • the abutting flat webs 4 of two adjacent parts of the protective tube 3 are sewn to one another by the seam 7.
  • the strop 12 is formed in that in the intermediate area 8 between the hanging eyes 9 two round sling parts 10, 11 are grouped together.
  • an abrasion protection pad 13 in the form of e.g. a textile band can be sewn or fastened by sewing (seams 7, 14) with at least one of the flat webs 4, 6.
  • FIG. 5 shows a round loop mat 18 produced using three round slings 3 or 12, with the hanging eyes 9 suspended in a lifting harness 17.
  • the round slings 3 are placed next to one another in the manner of strops 12. They are connected to one another by seams 7 and 14, which in turn are introduced into the flat webs 4 and 6, respectively.
