MACHINE FOR COMBING TEXTILE FIBER-S WITH INTERMITTENTLY-ROTATING NIP DRUMS. y

' Application filed January 9, 1928, Serial No.

Machines of the Schleifer type are known for the combing of textile fibers, (U. S. Pat; No. 1,408,780 and No. 1,425,059), upon which two or more intermittently rotating drums are provided, which are equipped on their peripheries with a number of nippers.

These nippers can close or open at a desired instant for the purpose of seizing in the required time the tufts or beards of the fibers to be combed, and holding them fast or releasing them. The tufts of fibers delivered to the nippers on the successive drums are combed at the head and tail ends by revolving combing cylinders, and finally delivered bythe nippers of the last 'drum'to a discharge device. v

The present invention relates to improvements in combing machines of the type described above. These improvements consist in subdividing the machine into as many independent units as there are nip drums, each of these units consisting of a machine frame in which one nip drum is arranged with its .conibingdevice and the auxiliary members associated therewith, while special means are provided for varying at will the relative positions of the above mentioned units both for the purpose of bringing them nearer together into a definite advantageous working position so as to obtain in the combed product the sorting of the fibers according to their'length, and for the purpose of moving them away from one another in order to facilitate inspection, repairor cleaning.

One constructional form of the invention in its application to combing machines of the above-mentioned type .with only two nip drums is illustrated diagrammatically and m'erelyby way of example in the accompany ing drawings, in which:

Figs. 1 and 2 show in side elevation,.partly in section, two constructional forms of such improved machines according to the invention.

Figure 3 illustrates a detail. For the purpose of facilitating the comprehension of the employments of the invention in combing machines of the above-mentioned type, the construction and the method; of working these machines will be briefly described and explained with reference to the constructional forms illustrated In the constructional example illustrated in Fig. 1, the combing machine comprises 245,454, and. in Germany January 13, 1927.

rows, with an intermittent and synchronous movement, the angular amplitude of which is equal to the, angle between two adjacent nippers. .VVith each cylinder there co-operate two combing cylinders 5, 6 and 5, 6, which revolve continuously and are so arranged as 'to correspondito the stopping position of two adjacent nippers. With each of the said combing rollers there cooperate revolving brushes 7 8 and 7, 8", which serve to remove the shortfibersfrom the teeth or needles of the combing cylinders. l/Vith the said rotatable brushes there cooperate stripper rollers (dofi'ers) 9, 10 and 9, 10, .while anoseillatable com'b 11 and 11 serves to remove fromthe last of these rollers the fleece of noil.

y In the example illustrated in Fig. 2 there isa simplified combing machine with a single combing cylinder 5 and 5 for each drum 1 and 1 and a single revolving brush 7 for 11' for removing the fleece of The method of working of combing ma- 1 chines of this kind is substantially as follows: 7 p

The ribbon 12 of fibers to be combed out is supplied at a-'to an open nipper 2, 3 of the drum 1. 'Aft er-the closing of this nipper an din consequence of a partial revolution of the cylinder, a tuft of fibers 13 1s detached. The tuft is combed out at the per of the cylinder 1 opens. In this manner the transfer of the tuft from one cylinder to the other is accomplished with reversal of the tuft. Next the tuft is combed at the tail end by the combing cylinders 5, '6, or

7 position required for orking.

of the adjustable stops 16 further consists by the single cylinder if there is only one, whereupon it 1s seized at "0 and discharged by an appropriate discharging de-- vice.

Now according.to the present invention each nip drum is arranged with its combing members and corresponding accessories in side an independent machine frame, while the various machine frames are so arranged that the distance between them, and therefore also between the nip drums carried by them, can be altered.

Thus in the example illustrated in Fig. 1, the drum 1 and its combing cylinder 5 and 6, and also the auxiliary devices 7, 8, 9, 10, and 11, are supported in a machine frame 15, which is distinct from the frame 15 which serves to support the drum 1." and the similar devices belonging to it. Moreover this latter machine frame 15 is slidably arranged on guides or slides 15 which-project in a longitudinal direction from the first frame,

consequently the frame 15 can be moved,

parallel to itself in such a manner as to vary the distance between the two frames and therefore between the drums 1 and 1. The

' smallest distance between the two frames 15 and 15' can be regulated at will by means of screw stops 16, which are adjustably secured to one of the two members, for instance to the member 15, and bear against the corresponding member 15 at the end of the movement of approach. In the example accord ing to Fig. 2 the arrangement is similar in the main, except that those auxiliary devices such as the brush 7 which are common to the two drums 1 and 1 maybe provided optionally on one frame or the other.

In consequence of the arrangement hereinbefore described, thetwo units of which the machine consists can be adjusted in any desired manner, the frame '15 being displaced on the guides 15 ofthe frame 15, as illustrated in dotted lines in Fig. 1. This 1 shifting apart, which can be effected to an optional extent, only limited by the length of the guides, presents advantages for the inspection, the repair or the cleaning of the two units. I By the aid of the stops 16, whenever the two units are moved nearer together they are readjusted afresh into the exact The object in enabling the minimum distance between the two cylinders 1 and 1 duringthe working to be. altered in almost imperceptible stages, this being for the purpose of altering the combing effect which is intended to be obtained. This will be clearly seen by considering Fig. 3, in which one nipper 2, 3 of the drum 1, and, in dotted lines, different positions of thecorresp'onding nipper 2, 3

of the drum 1, are shown in the correspondencewith zone b, in which the delivery of the tuft 13 from one cylinder to the other takes place with reversal, this tuft being diagrammatically illustrated as consisting of fibers of different lengths. It is clear that the nearer the nipper 2, 3 is brought to the nipper 2, 3, the greater will be the quality of fibers seized and retained during the ensuing combing of the tail end of the tuft, while by increasing the distance between the said nippers',-the fibers that are below a particular length are not seized, and will pass into the noil during the subsequent combing. By regulating the distance between the nip cylinders it is thus possible. to eliminate from the combed material the fibers that do not attain a certain length.

Although the invention is only shown in its application to a combing machine with two nip drums, it will be: immediately recognized that it is also applicable to combing machines of the same type with any number of cylinders. It is moreover also obvious that the invention is by no means limited to the diagrammatic arrangements described and illustrated but that it may undergo,

without departing from its fundamental idea, all the modifications which are required in practical use.
