Definitions

  • the invention relates to a card for the production of tangled or longitudinally oriented nonwovens made of fiber material, with at least one feed roller or the like., If necessary, a roughing roller running in the same direction and at least three downstream of the roughing roller, working drums of the same diameter running in the same direction and preferably in opposite directions to the roughing roll , of which two are in mutual engagement and whose relative speed and / or mutual distance for controlling the proportion of the fiber material that can be restored on the respective work drum on the one hand, and the fiber material that can be transferred to the respective downstream work drum on the other hand, can be set.
  • a card of the type described above is known, in which the working drums follow one another essentially linearly, in such a way that three working drums interact.
  • the known carding machine enables larger working widths to be achieved with reduced design effort compared to the previously customary procedure at high working speeds while ensuring the uniformity of the random nonwoven structure over the entire working width and has proven itself in practice, but it has turned out to be desirable, one to be able to enable an even greater storage capacity of fibers in the clothing and thus also a higher throughput of the fibers and a more intensive mixing of the fiber material. This is particularly advantageous when processing melanges.
  • the invention is therefore based on the object of developing the generic card in such a way that an even greater uniformity of the random nonwoven structure can be achieved with a higher throughput.
  • this object is achieved with a card of the generic type in that the working drums are arranged on the circumference of at least one central roller running in the same direction and are in adjustable engagement therewith.
  • the relative speeds and / or the distance between the working streams on the one hand and the central roller (s) on the other hand are adjustable.
  • the invention also proposes, if necessary, that two central rollers running in the same direction are provided.
  • Another embodiment of the invention provides that the two central rollers have the same diameter.
  • the relative speeds and / or the distance between the two central rollers are adjustable.
  • the invention also provides for the working drums to be lined on their side facing away from the central roller (s) with cover boxes which engage in the respective gusset area.
  • cover boxes are designed as air guide boxes.
  • air boxes according to DE-PS 33 15 839 are provided, which have an effect described there, so that reference is made to the statements there.
  • compressed air can be applied to the cover boxes.
  • the invention may also provide that at least one of the cover boxes is provided with carding segments on its side facing the working drums.
  • cover boxes replace the otherwise usual protective hood cover.
  • carding segments are provided on the last cover box (s) preceding a pickup roller.
  • the invention enables an extraordinarily uniform nonwoven structure to be achieved in a significantly improved manner and with high throughput, this being caused in particular by the high storage capacity of the working drums and the central roller (s) and, on the other hand, the achievable high peripheral speeds.
  • the card in the embodiment shown there has a feed roller 10 which interacts with a feed trough.
  • a feed roller 10 which can run, for example, at a rotation speed of 10 m / min, acts on a roughing roller 12 running in the same direction, whose speed of rotation can be, for example, about 300 m / min.
  • the preliminary roller 12 the surface of which, like that of the feed roller 10 and also, in the exemplary embodiment shown, that of all the downstream rollers or drums, is provided with an appropriately designed sawtooth set, is followed by a first working drum 14 running in opposite directions with the preliminary roller 12, which in turn again cooperates with a second working drum 16, which hereby runs in the same direction.
  • the second working drum works with a third working drum 18, the third working drum 18 with a fourth working drum 20, the fourth working drum 20 with a fifth working drum 22, the fifth working drum 22 with a sixth working drum 24, the sixth working drum 24 with a seventh working drum 26 and the seventh working drum 26 together with an eighth working drum 28, wherein all working drums run in the same direction with one another and are in mutually adjustable engagement.
  • All the working drums 14 - 28, like the roughing roll 12, are arranged on the circumference of a central roll 30 which runs in the same direction as the working drums and with which the working drums are in turn in adjustable engagement.
  • the peripheral speeds of the working drums 14-28 as well as the central roller 30 can be up to 2000 m / min. Not only are the mutual distances of the working drums 14-28, which are successively engaged, but also the distance between the individual working drums 14-28 from the central roller 30 adjustable so as to take into account the special features of the fiber materials to be processed.
  • the diameter of the central roller 30 can be selected differently, and depending on this, the number of the working drums 14-28 surrounding it on the circumference can also be different.
  • Each individual roller or drum can be given its own drive in the exemplary embodiment shown in FIG. 1 as well as in the embodiment to be described below with reference to FIG. 1.
  • an upper take-off roller 32 and a lower take-off roller 34 Downstream of the working drums 14 - 28 are an upper take-off roller 32 and a lower take-off roller 34, which run in opposite directions to the working drums 26 and 28 which are in engagement with them and can have, for example, a peripheral speed of approximately 120 m / min.
  • the working drums 14-28 are clad on their outer side facing away from the central roller 30 with cover boxes 36-50 which engage in the gusset area between successive working drums and can be acted upon with compressed air in the embodiment shown, so that they are effective as air guide boxes in the manner known from DE-PS 33 15 839.
  • the last cover boxes 48 and 50 preceding the take-off rolls 32 and 34 are also provided with carding segments on their side facing the central roll 30, which gives a further possibility of influencing the longitudinal orientation of the fibers in the pile.
  • FIG. 2 differs from that of FIG. 1 in that two central rollers 30, 31 of the same diameter are provided, which are in mutually adjustable engagement and run in the same direction with each other.
  • the carding machine works in such a way that the incoming fiber material is guided over the working drums 14-28 and the central roller 30 or the central rollers 30, 31 with adjustable partial restoration and is worked through intensively in the process.
  • the mode of operation of the intermeshing working drums together with the central roller corresponds approximately to that of the working drums according to DE-PS 35 32 021, but because of the large diameter of the central roller 30 or the central rollers 30, 31 on the one hand and the large number of working drums 14 which this makes possible - 28 on the other hand, together with the considerable peripheral speed of the working drums and the central roller (s), a considerably higher storage capacity of fibers in the clothing is available and thus a considerably higher throughput of fiber material can be achieved.
