COTTON DRAWI NG FRAME Filed Jan. 19, 1934 a y W l f 3 w J .2 1
Patented Dec. 24, 1935 UNITED STATES PATENT OFFICE COTTON DRAWING FRAME Erich Langen, M-Gladbach, Germany I Application January 19, 1934, Serial No. 707,323 2 Claims. (01-19-131) In cotton drawing frames with pairs of drawing rollers, six or eight carded slivers are generally fed close together side by side to the pair of feeding rollers and after the drawing, the fleece is united to form a single sliver which is then caught in a can. This doubling six or eight. times necessitates a great width of the drawing rollers, wherefrom results that the fibres are not reliably guided at the sides of the fleece and consequently irregularities in the delivered sliver are caused. Therefore, it has already been proposed to separately draw the slivers on cotton drawing machines and to unite them only behind the delivery rollers.
With regard to the high draft this has hitherto been used successfully only in fine spinning machines and fiyers. It has already been-proposed, to employ it in instance one conveyor band for high drafting, of correspondingly large width, was selected for all the slivers to be doubled, that is for six to eight slivers. The great width of the conveying bands is, however, the reason that crooked running soon occurs so that the conveying bands wear on one side in a very short time and become useless. Moreover, the extraordinary width of the conveyor band places such high requirements on the leather as regards uniformity of density and stretching, that it is practically impossible to procure the same.
According to the invention one system of high draftingds provided for each sliver, or for example for two slivers of one supply, and the slivers of one supply thus drawn are doubled to form a single sliver after leaving the delivery rollers. By this subdivision an improvement in the guid-- ing of the fibres is attained, because for example only a few.slivers are dubled and drawn per subdivision, The slivers of several subdivisions thus drawn "are then unitedto form one single sliver.
Two embodiments of the invention are illustrated in the accompanying drawing in which:-
Fig. 1 shows in side elevation a cotton drawing frame for' high drafting with conveyor bands.
" Fig. 2 is a top plan view of Fig. 1.
Fig. 3 is a front elevation of Fig. 1.
Fig. 4 shows the conveyor band guide pulleys in side elevation on a larger scale.
Fig.5 is a front elevation showing a high draft ing system by means of fluted rollers.
By means of a pair of feed rollers, b, c and a sliver distributor d the cotton slivers a 'are fed singly or with slight doubling to the drafting mechanism which consists of pairs of rollers e, f,
cotton drawing frames, in which exactly as 'in Fig. 2, a few,
9, 71.. An independent high drafting frame comprising two endless bands i is arranged between the pairs of rollers g and h for each sliver or, according to Fig. 2, for example, for. every two slivers. Behind the pair of front rollersh the 5 separately drawn slivers are again united to a single one in the'delivery funnel m; I
As can be seen from Figs.'1 to 3 the guide cage for the three pairs of conveyor bands of one supply is made in one piece. It consists of longitudinal bars 12 and transverse walls o cast or otherwise fixed thereon. The rollers 9 have turned. groovesp, Fig. 2, in which the transverse walls .0 with slots q are secured-against lateral displacement; Pulleys r and s serve for the front guid- 15 ing of the conveyor bands-i, k. The upper pulleys r of a delivery are loosely mounted on a commen rod t, whereas the lowerpulleys 's are each loosely mounted on a guide rod u, so that they can be easily removed from'the cage. The-rods t and u are secured against, lateral displacement in some suitable manner. The pulleys r and s cannot shift in lateraLdirections. because they are each situated between two-cagewalls 0.
The upper guide pulleys r for the conveyor bands i of a delivery are jointly weighted. For this purpose saddles 12 rest on the rods t and are weightedby a common weight 10. To have the weight distributed uniformly on all g conveyon' bands, the following arrangement is provided. A cord 3:: engages the two outer saddles v .and is guided over pulleys y of an intermediate elementv z and. pulleys 2 of the middle saddles-v.
Fig. 5 shows the employment of a fluted drawing frame according to for example two, of the supplied slivers are guided by subdivided fluted cylinders 3, 4, 5 arranged side by side, and are doubled to form a single-sliver behind the pair of front rollers. Any other system of high 40 draftmay be employed instead of the conveyor bands or grooved drawing frame, as mentioned above. I
