Definitions

  • a further disadvantage belongs to'those fibrous products which have been obtained by cutting the hanks collected on reels or drums and subsequently manipulating them 1n the form of lengths, namely that it is impowble to avoid fraying and felting together of the ends of the lengths. There follows 1n the carding machine a series of obvious dlsadvantages.
  • the spinner wants a band which can be mac e, for instance the carding machine, he must have a titer (thickness) as far as possible constant.
  • titer thickness
  • To this requirement for qllllahty must be added the necessity for the c eapest possible conditions for mass product on, mvolving, among other things, the ehmlnation of wages as far as possible.
  • Fig. 1 is a diagrammatic elevatlon and Fig. 2 a plan of a machine for making the primary fibrous product.
  • Fig. 3 1s a detail vlew;
  • Fig. 4 is a sectional elevatlon of a palrofwinding drums drawn to an enlarged scale, and
  • Figs. 5 and 6 are detail sectional views also drawn to an enlargedl scale.
  • a strong band of fibers is formed by leadmg the bundles of threads issuing from the several spinning nozzles on their way
  • the spinning tables may be constructed of an length and very close to each other, for exyioo ' ample at a distance of 1 metre.
  • a further new feature'of the invention resides in the fact that between the auxiliary draft wheel and the subsequent washing bath there is a comparatively long distance (F-G) through which the band must run.
  • This distance in which the band runs over a suction and draining trough (H) at a height suitable for manipulation above the floor, is provided for the purpose of giving the spinner, both when the whole apparatus is started and also duringthe changing of the several groups of nozzles, .time and opportunity to clean the newly arriving threads, either directly or after previous short draft on the auxiliary draft roller, from all portions of fiber of varying titer which are unavoidable in the spinning operation, and to splice this bundle of threads with the main threads in order that it may share the forward movement without in any way being damaged. It is especially necessary for this purpose that the splicing should be possible with avoidance of free projecting ends.
  • -A travelling platform J is provided for the operator. I r
  • the band is compensated the washing liquid and for superintending the apparatus.
  • the said automatic washing operation according tothe invention occurs essentially while the band is passing in numerous turns over pairs of drums (K, K) or quite generally groups of drums, made of enameled iron or the like.
  • the band is led over or around the drums or pulleys with a speed suited to the spinning operation and increased or diminishedin limited degree only by shrinkage and stretching. (stretching is to be avoided as far as possible).
  • the band is brought into intimate contact with the washing liquid in general on the tan ential portions of the path, and the liquid ta en up is in part again expressed on the pe'ripheral portions of the path owing to the pressure of the band against the surface of the drum. In this manner there is produced a very vigorous alternating action of the liquid on the fibers.
  • the peculiar and novel action of the washing and drying device is as follows (5)
  • the drums or pulleys have a large diameter, for example 80 centimetres or more.
  • the effect of this is that 'a chance adhering thread end, before it arrives at thectangential path leaving the drum, has time to be torn loose on the periphery of the drum.
  • the drums are internally heated by steam or a liquid.
  • steam thus gen- 1 erated on the heated wall of the drum, any serious adhesion of the threads is prevented.
  • the further advantages of the large drum are as follows Owing to the large diameter of the drum the total heating effect within the washing and drying apparatus is increased. The number of rotations is diminished, as is de-- sirable, and slipping of the band on the drum is avoided. A still more important good effect of the large diameter drum-is that the curvature of the band is comparativelysmall, so that the band can be kept in the desired stretched condition. Repeated passing of the band over rollers or the like of small diameter produces an objectionable buckling and entangling of the mass of fibers.
  • the invention provides that the peripheries of the drums over which theendless band passes in succession shall increase or diminish at the places where the changes of length occur, that is to' say, ar-
  • the travelling band is subdivided throughout its cross section very favourably for inter enetration of the washing or other liquid ig. 5, 0,0, 0).
  • the rails are hollow and the pro jections or ribs (N, N Fig. 5) are formed as sprayingnozzles.
  • These comb bars are provided laterally with spring balances which show the tension exerted on the band, or instead of such spring balances the rails may be connected with counter-weights (O, 0, Fig. l) suspended over. rollers.
  • the up r drum of a pair of drums or the topmost rum of a group of drums may be capable of a rising and falling movement, as illustrated in Fig. 4, accordingly as the pair or group of drums is exerting toohigh or too low a'tension on the band.
