  • the present invention relates to the treating of fibrous material in general, more particularly to the treating of fibrous material in continuous ringless spinning of such material.
  • the continuous ringless spinning of fibrous materials utilizes spinning chambers which rotate about a vertical ,axis of rotation and which have an inner peripheral surface onto which oriented fibers, obtainedby carding fibrous sliver, are fed in a continuous stream. Under the influence of centrifugal action the fibers are deposited on the surface in form of a. cohesive ribbon which can be withdrawn, usually in the direction of the axis of rotation of the spinning chamber, in form of a yarn.
  • a spinning chamber of this type is, for instance, described in the above-mentioned copending application of M. Kubovy et al., Ser. No. 598,275.
  • Spinning chambers for the continuous ringless spinning ,of fibrous material arein the prior art each associated with a carding roller which cards the sliver, that is which separates thefibers of the sliver and orients them preparatoryto their deposition in form of a continuous stream .onto the inner peripheral surface of the spinning chamber.
  • the carding roller a'lone' is not sufficient for this .purpose, since additional mechanisms such as feed roller. and supporting equipment are used for supplying the sliver to the carding roller and for rotating the carding roller, controlling its speed of rotation, and other func- ,tions.
  • additional mechanisms such as feed roller. and supporting equipment are used for supplying the sliver to the carding roller and for rotating the carding roller, controlling its speed of rotation, and other func- ,tions.
  • Such arrangements are relatively elaborate and therefore-also relatively expensive.
  • arrangements of this type which are known from the prior art are actuallyeven more expensive than would appear at first sight because. each of the carding or combing rollers thus provided is very inefficiently utilized. This will be understood if it.
  • the present invention provides an arrangement in which the available circumferential surface of a carding instrumentality, particularly a carding roller is utilized with a high degree of efiiciency.
  • the present invention provides an arrangement wherein a single carding instrumentality, such as a carding or combing roller, can serve at least two rotary spinning chambers for supplying oriented fibers thereto.
  • a single carding instrumentality such as a carding or combing roller
  • I provide an apparatus for treating fibrous material comprising carding means which is operative for converting fibrous sliver into oriented fibers.
  • carding means which is operative for converting fibrous sliver into oriented fibers.
  • Associated with the carding means is a plurality of feeds arranged for respectively supplying sliver to the carding means.
  • spinning means each of which are associated with one of the feeds and which are arranged to receive oriented fibers obtained from sliver supplied by the respective feed.
  • Detector means is provided and is associated with the respective spinning means for detecting breakage of yarn issuing therefrom.
  • arresting means is provided, such arresting means being operatively connected with the detector means and with the respective feeds and being responsive to signals produced by the detector means for the purpose of arresting the supply of sliver by any of the aforementioned feeds in response to breakage of the yarn which issues from the spinning means associated with such feed.
  • FIG. 1 is a vertical sectional elevation of a device embodying my invention
  • FIG. 2 is a side-elevational view of the device shown in FIG. 1.
  • a housing which is generally indicated with reference numeral 1 and which is provided with an inner chamber wherein there is arranged a combing or carding roller 3 which is fixedly mounted on a rotary drive shaft 2 and which can thus be rotated in the direction of the arrows shown in FIG. 1.
  • the outer circumferential surface of the carding roller 3 is of cylindrical cross section and is provided with a great number of outwardly projecting needles or other suitable projections indicated with reference numeral 4. It will be understood that these needles 4, when they engage the fibrous sliver, serve to comb or card the same so as to orient the fibers thereof preparatory to introduction of the same into a rotary spinning chamber.
  • the housing 1 is provided with an outlet channel 5 and, diametrally opposite the outlet channel 5, with a similar outlet channel 5.
  • Each of the outlet channels 5, 5 extends into the inlet of a respective rotary spinning chamber 9, 9' and these spinning chambers are respectively provided with guide surfaces 7, 7 which extend to and terminate at collecting surfaces 8, 8'.
  • Each of the spinning chambers 9, 9 is further provided with one or more exhaust passages 10, 10 and with a tubular shank, respectively designated with reference numerals 12 and 12', which are supported in respective bearings 11, 11 for rotation therein.
  • the rotary spinning chambers 9, 9' are arranged on diametrally opposite sides of the carding roller 3 so that they rotate about an axis which is common to both.
  • a stationary yarn-withdrawing tube 13, 13' is provided in the respective spinning chambers 9, 9 and passes through the respective hollow shanks 12, 12'.
  • the yarn 16, 16 being withdrawn from the respective chambers passes between a set of positively driven withdrawing rollers, identified in the case of spinning chamber 9 with reference numeral 14 and, in the case of spinning chamber 9, with reference numeral 14.
  • the rollers 14, 14 rotate in mutually opposite directions as indicated by the respective arrows.
  • the yarn 16, 16' being withdrawn by these sets of rollers 14 and 14' is checked for breakage by yarn detectors 15 in the case of the yarn 16, and 15' in the case of the yarn 16. After passing the respective detectors 15, 15 the yarn is then wound onto bobbins 17 and 17, respectively.
  • a feed roller 19 which is driven, via a suitable clutch 20, by a drive means 21 of any well known type.
  • the clutch is controlled by an impulse device 22 which in turn is operatively connected with the yarn-breakage detector 15 so that, when the latter detects a breakage in the yarn 16, the signal generated by the detector 15 will cause the impulse device 22 to disengage the clutch 20' so as to thereby interrupt drive of the feed roller 19 in the absence of yarn 16.
  • a funnel-shaped inlet 24 discharges into a clearance established between the outer circumferential surface of the feed roller 19 and the surrounding wall of the housing 1 and sliver 25 which is fed into the inlet 24, passes into the clearance 23 wherein it is conveyed by the feed roller to pass into engagement with the teeth 4 of the carding roller 3 so that the fibers of the sliver 25 are then separated and oriented.
  • Such separation and orientation takes place during passage of the fibrous material from the feed roller 19 to the outlet 5 which it leaves in form of a stream 6 of oriented fibers.
  • the shape and length of this path between the feed roller 19 and the outlet 5 must be so chosen as to insure satisfactory separation of the fibers.
  • a sensing, coupling and impulse-providing arrangement similar to that just described in conjunction with feed roller 19 is also provided in conjunction with a second feed roller 19' which is also arranged in a recess of housing 1, such recess for the feed roller 19 being located downstream of the rotary spinning chamber 9 but upstream of the rotary spinning chamber 9'.
  • the elements of this arrangement associated with the feed roller 19' are identified with reference numerals identical with those used to identify the elements associated with feed roller 19, but are each provided with a prime.
  • the stream 6 of oriented fibers can be separated from the surface of carding roller 3 in various ways, which are of no consequence in connection with the present invention, but which may primarily include the suction effect which is obtained when air is exhausted from the interior of the respective rotary spinning chambers 9, 9' through the exhaust passages 10, 10' thereof. If some of the fibers should nevertheless pass beyond the respective outlets 5, 5' and not be doifed, then they will pass on to the next-following outlet, that is if they have passed the outlet 5 they will move onto the outlet 5, and will then be added to the stream of fibers which enters into the spinning chamber associated with that particular outlet.
  • the feed roller 19 or 19' associated with the respective spinning chamber is stopped, so that no further sliver and thus no further fibrous material passes onto the surface of the carding roller 3 for being conveyed to the spinning chamber whose yarn has broken, whereas the supply of sliver and thereby of oriented fibers to the other spinning chamber, whose yarn is not broken, continues without interruption.
  • the number of carding rollers which was heretofore necessary is reduced at least by one-half; that is, two spinning chambers can be serviced by a single carding roller with the resultant economies of manufacture and of operation.
  • the invention is not limited to the utilization of only two spinning chambers with their associated feed and control arrangements. Rather, a greater number of spinning chambers and associated control arrangements can be provided if desired to thereby utilize the circumferential surface of the carding roller even more fully. Also, it is conceivable to use another type of carding instrumentality instead of a carding roller, and all such modifications are intended to be encompassed by the protection sought herein.
  • Apparatus for treating fibrous material comprising, in combination, carding means operative for converting fibrous sliver into oriented fibers; a plurality of feeds arranged for respectively supplying sliver to said carding means; a plurality of spinning means each associated with one of said feeds and arranged to receive oriented fibers obtained from sliver supplied by said one feed; detector means associated with the respective spinning means for detecting breakage of yarn issuing therefrom; and arresting means operatively connected with said detector means and the respective feeds and responsive to signals produced by said detector means, for arresting the supply of sliver by a feed in response to breakage of the yarn issuing from the spinning means associated with said feed.
  • said spinning means includes a plurality of rotary spinning chambers each arranged to rotate about an axis normal to the axis of rotation of said rotary carding roller, and each having an inlet proximal to said circumferential working surface thereof.
  • said plurality of spinning chambers includes a first and a second spinning chamber respectively associated with said zfirst and second feed, and wherein said inlets of said first and second spinning chambers are angularly spaced from the associated feed and located downstream thereof, so that sliver supplied by the associated feed and converted into oriented fibers by said carding roller is supplied to the respcctive spinning chamber in response to rotation of said carding roller.
  • said detector means includes two detectors each associated with one of said spinning chambers downstream thereof for detecting breakage of yarn issuing therefrom.
  • feeds each comprise a feed roller and a drive for rotating said feed roller about an axis of rotation.
  • said arresting means includes actuating means operatively associated with the respective detector and the respective associated drive for arresting the latter in response to receiving a signal from the respective detector indicating yarn breakage at the spinning chamber associated with the respective drive.
