Definitions

the invention relates to a card for nonwoven production from fiber material with at least three mutually adjustable engagement, working drums of the same diameter running in the same direction, preferably with at least one feed roller or the like, one in the same direction with a warp between 100 and 200 running preliminary roller, at least two downstream of the roughing roller, working drums of the same diameter running in the same direction, the speed of which is greater than that of the roughing roller, and at least one take-off roller assigned to the last working drum, with the roughing roller or one of the first working drums immediately downstream of it, each have two working drums, which are jointly followed by another working drum, and the relative speeds and / or the mutual spacing of the working drums for controlling the proportion of the fiber material that can be restored to the respective working drum, on the one hand, and that of each downstream work drum transferable fiber material on the other hand are adjustable, as described in DE-OS 35 32 021.
a card is known in which the downstream work drums are designed as a main roll, each with a downstream tangling roll, and furthermore, as is customary for cards of the type in question, at least one pair of each Workers and turner rollers are arranged.
the worker turner rolls which in the device described above have a generally smaller diameter than the main whirling roll (s), serve the purpose of ensuring sufficient carding of the fiber material, while the tangling roll (s) pursues the purpose, or .
DE-OS 35 32 021 proposes a clutter of the generic type in which, with a reduced design effort at high working speed, the achievement of higher working widths while ensuring a largely uniformity of the random fleece structure over the entire fleece width, in which with complete dispensing with the until then a satisfactory worker turner roller regarded as indispensable Carding effect and uniformity of the nonwoven to be produced can be achieved over the entire width of the nonwoven even with the largest possible machine widths, in that the fiber material is guided with adjustable partial restoration over at least three mutually adjustable working drums of the same diameter.
This combined with the adjustability of the relative speeds and the relative positions of the individual work drums, with a corresponding design of the surface structure, namely in the form of sawtooth sets or the like, can be created on each individual work drum in a controllable manner.
a wedge-shaped air guide box engages in the transfer area between the main roller and the tangled roller or the tangled roller and the main roller, which is vertically and transversely to Roller jacket is arranged adjustable.
This air guide box which can either be depressurized or can be pressurized with air under high pressure, but cannot be subjected to negative pressure for suction, improves the strong air turbulence present in the fleece formation area between interacting working drums in such a way that optimal and uniform fleece formation is further promoted.
the invention has for its object to develop the card according to DE-OS 35 32 021 in such a way that the tangled nonwoven process in the transfer area between interacting working drums are further improved while increasing the possibilities of influence can.
this object is achieved in that at least one of the transfer areas between interacting working drums (each) is assigned an essentially wedge-shaped protruding into the transfer area, adjustable in height and transversely to the drum jacket.
the air guide box is hollow, provided on its side faces perpendicular to the drum casing with connecting pieces, and is provided with air passage openings on at least one of the surfaces facing the working drums and can be pressurized with compressed air.
the invention optionally provides that the surface of the air guide box which points directly to the transfer area between the working drums is provided with air passage openings.
sliding plates which are displaceably mounted with corresponding air passage holes are assigned to the surface of the air guide box provided with air passage openings.
the basic idea of the invention is to provide an air guide box in the card according to DE-OS 35 32 021, as is already known from DE-PS 33 15 839 in connection with the card according to DE-GM 82 18 526 is.
This makes it possible to form the random web in the transfer area to which the air guide box is assigned, or in the transfer areas to which the air guide boxes are assigned to improve between successive, interacting working drums, as also by means of the air guide box according to DE-PS 33 15 839 in the card according to DE-GM 82 18 526 or the corresponding DE- PS 32 24 118 is the case.
the advantageous mode of operation of the air baffle box reference is therefore expressly made to the relevant statements in DE-PS 33 15 839.
the card according to the invention has a feed roller 10 which, as in the case of the generic card, can interact with a feed trough or the like; Of course, several feed rollers or troughs can also be provided.
the roughing roller 12, that is runs in the same direction with the feed roller 10 and its surface is like that of the feed roller 10 and also, in the exemplary embodiment shown, is provided with a correspondingly designed saw tooth set for all downstream rollers or drums, a counter-rotating first working drum 14 is arranged downstream, which in turn is in turn cooperates with a second working drum 16 and a third working drum 18.
the second working drum 16 and the third working drum 18 act on a fourth working drum 20, which in turn is followed by a fifth working drum 22 and a sixth working drum 24, the fifth working drum 22 and the sixth working drum 24 being in turn followed by a seventh working drum 25.
the working drums 14, 16, 18, 20, 22, 24 and 25 each have a rotational speed of, for example, approximately 1400 m / min.
the relative speeds of the working drums as well as their relative spacings, ie the width of the respective roll nips, can be set .
the working drums 14, 16, 18, 20, 22, 24, 25 are followed in the manner shown in the drawing by two take-off rollers 26, 27, which run in the opposite direction to all the same-running working drums with a peripheral speed of, for example, about 116 m / min. to run.
the drawing also shows transfer areas 28, in which the fiber material is transferred, and storage areas 30 for the fiber material on the individual working drums.
the drawing shows air guide boxes 32 which are adapted to the corresponding shape of the respective working drums and which are each wedge-shaped in the respective transfer areas intervene between interacting working drums.
the feed roller 10 conveys fiber material in a known manner to the pre-roller 12 in a uniform manner.
the first working drum 14 which runs with considerable delay, as shown, in opposite directions removes the fiber material and cards it in a first step in connection with the second Work drum 16 and the third work drum 18.
not all of the fiber material taken over from the first work drum 14 by the pre-roller 12 is immediately transferred to the second work drum 16 or the third work drum 18, rather only that in the transmission area 28, as shown in the drawing visible part, while the portion of the fiber material present in the storage area 30 is recycled one or more times and subjected to a further carding.
the take-off roller 26 in the place of which, of course, a multiple roller take-off or the like could also be provided in a known manner, as is also provided in the generic device, possibly also combined with an upsetting roller take-off described there which runs considerably slower than the working drums, so that a relatively strongly "pushed together" fleece is pushed onto it.
the air guide boxes 32 which can be depressurized, but preferably can be acted upon with compressed air in a manner known per se from DE-PS 33 15 839, can be used in the transfer areas between the interacting working drums in particular because of the Influence high turbulence occurring at high speed of the working drums, in the case of a "pressureless" design of the air guide box in question, in that the air guide box forms a resistance to the air movement, and in addition if the air guide boxes are positively pressurized by air, this also influences the flow caused thereby.
the intensity of the air flow or, overall, the influence of the turbulence achieved in the respective transfer area has a direct influence on the uniformity and on the whole the tangled nonwoven structure of the fiber material located there.
the air guide box 32 or the various air guide boxes 32 provided in the respective transfer areas not only make it possible to influence the turbulence in the respective transfer areas, but it is also possible in this area to add the fiber material already pre-carded, including powder, for example. Granules or the like, as described as a whole in DE-PS 33 15 839, to which reference is expressly made to explain and supplement the inventive concept.
the nonwoven material obtained by means of the card according to the invention according to exemplary embodiment FIG. 1 is uniform over the entire operation of the machine and has a ratio of longitudinal to transverse strength of approximately 1: 1, as is desired.
the working drums of the same diameter can be produced without bending even with very large working widths of the machine. In addition to eliminating the problem of roll deflection, the absence of worker and turner rolls ensures a considerably simpler construction.
two working drums 14, 16 cooperate with the roughing roller 12, which are followed by further working drums 18, 20, 22, 24 and 25 in the manner shown in the drawing, which are assigned to one another in such a way that the fiber material brought in by means of the feed roller 10 is further transferred or stored back to the desired extent by the individual working drums, the front roller 12 of course not being involved in the storage.
the speeds of rotation of the feed rollers 10, the pre-roller 12 running in the same direction as well as the work drum 12, 14, 16, 20, 22, 24 and 25 running in the opposite direction as well as the take-off rollers 26, 27 are correct with the values given in connection with FIG match. Otherwise, the device operates in the manner explained above with reference to the exemplary embodiment in FIG. 1.
