FLECHTPACKUNG

The invention essentially concerns a Flechtpackung with several outside soul strands in oh direction of the packing, with several braiding strands, which are twisted around the soul strands and with several rows of chaining strands, which are twisted between the rows of braiding strands. Flechtpackungen are comprehensively used in the industry for numerous sealing purposes. Packings become typical from flax, jute, Asbestoder synthetic (for instance made fibers, which will intertwine formed to threads or strands and with one another of polytetrafluoroethylene} -. The result is typically a packing with square cross section and a Fischgrät Webmuster, which extend along the packing axially, typical such packings I0 is represented in the US-PS Nr.3, 646.846. If usual past packings are wound around a wave, they result in however no even Faserdicbte. If they are wound around one while, the packing fibers at the inside diameter are squeezed together, while those are stretched at the outside diameter. In the case of a packing with initially square cross section results a trapezoidal cross section with a Leekweg, which is larger at the outside diameter than at the inside diameter. Furthermore the seals characteristics of typical packings are, whereby for causing a sealing a considerable squeezing together is necessary, squeezing the packing together as a check of leakage losses statically cause a increased pressure at the wave and press the lubricant from the packing, produce an overheating and a shortening of the life span of the packing and contribute to the wave wear. In the US-PS Nr.4, a Flechtpackung is indicated 100.835 as a turning spin. The packing has a density of improved uniformity and necessarily for sealing a lower pressure, whereby the life span of the packing and the wave is erhüht. The packing has also hydrodynamic seals characteristics, if it is aligned in relation to the wave turn suitably, decreases the necessary sealing printing and contributes to a increased life span of the packing and the wave. In the US-PS Nr.4, 100.835 indicated procedures and the there device limit however the kind of the producible twisted network. Thus only the fundamental braiding strands can be used with the production of the network, which extend all in the same spiral direction. Itself coiled in the opposite direction erstreekende Keit strands cannot be used due to the own restrictions of the indicated procedure for the production of the network, which normally requires stopping that braiding strands basic course. The inability for the use of chaining strands in the network limits the size and density of the packings, which can be manufactured with a spiral spin. Regarding the Drellrichtung in the threads used as braiding strands it is additionally desired that the enterprise of the Flechtvorrichtun is limited a direction to twisting the braiding strands. Thus a suitable network is produced, which exhibits a spiral spin in only one direction. Task of the invention is, the creation in particular a Flechtpackung with a spiral spin, which can run in arbitrary direction, in particular chaining strands a using twisted Flechtpackung. This task is solved on the basis of a Flechtpackung of the initially described kind according to invention thereby that the outside soul strands and the numbers Umflechtund of chaining strands are coiled along the packing that a network forms the soul strands with the Beihen of braiding strands and rows of chaining strands, running between them, which exhibits a spiral spin in a direction that the braiding strands extend over the soul strands in a spiral direction under an angle to the soul strands and that the spiral spin and the rescue strands extend in a spiral direction, which is opposite those, in which the braiding strands extend. By the term “spiral spin of the network” is understood in the context of the invention that exhibiting network a tendency does not possess this spiral spin, to untwist itself again. Fundamental one supplies the invention a Flechtpaokung with several rows of braiding strands, which extend coiled along the Paokung and form a network with a spiral spin. The braiding strands extend coiled under an angle to the rows and to the spiral spin. With an execution form they extend in the same spiral direction as the rows. With certain execution forms of the invention chaining strands form rows between the numbers of the braiding strands, whereby the gett strands in a spiral direction extend, which is opposite those, in which the braiding strands extend. With special out the invention are intended a centric soul strand and outside soul strands führuagsformen, over which the braiding strands are twisted. The invention concerns briefly summarized a Flechtpackung with several outside soul strands, which are together-twisted with several chaining strands, whereby the outside SeelenI0 of strands extends coiled along the packing and forms with the chaining strands a network with a spin, which extends coiled in a direction. The nice strands extend over the soul strands in a continuous spiral sample under a /inkel to the outside soul strands and for the spiral spin of the network. Several in} borrow process between the braiding strands end l< Ett strands extend coiled in a direction opposite to the braiding strands. A device is in particular such with a swivelling strand collecting tank, which can seize the network at the point, to which, serving for the production of the Flechtpackung, the braiding strands for the Zusammenflechten extends, as well as mechanism to turn strand collecting tank, whereby the Flechtverfahren covers the rotation of the network on dern point, at which the braiding strands gather. The invention is for example described on the basis the design. In it the figure shows a side SCN view of a packing with special representation of the Verfleehtuug of the Paokungsstränge, manufactured in accordance with the invention. The design shows the structure of a packing --10--. The packing --10-- has a centric soul strand --12-- and several (here four) expresses soul strands --14--. The soul strands --12 and 14-- have in each case several threads from selected packing fibers. Around the soul strands --12 and 14-- several braiding strands are in a usual Gitterflechtmuster --16-- and gentleman strands --18-- twisted. The braiding strands --16-- are like that around the outside soul strands --14-- twisted that each braiding strand --16-- itself over an outside soul strand --14-- at the packing surface extends. All braiding strands --16-- extends essentially coiled in only one direction and points a coiled sample of parallel braiding strands --16-- up, which extend in rows along the Packnngsoberfläche. The chaining strands --18-- extend in between the numbers of the braiding strands --16-- running rows in the opposite direction. The outside soul strands --14-- extend coiled along the packing surface, form together with the braiding strands --16-- Ribs with slots in the place of the chaining strands present between them --18-- and form a network with a spiral spin of the Hauptflechtmusters. With special execution forms the spiral describes --10 to 13-- Revolutions around the packing meter of the packing per current. The braiding strands --16-- run under an angle to the spiral of the network nnd extend with the represented execution form coiled in the same general direction as the network spiral.
