Definitions

  • the improvement forming the object of the present invention overcomes this difliculty and consists in fitting the cylinders carrying the endless belts, both top and bottom, with belts, so that the movement of the up er cylinder is effected positively in place 0 its being transmitted by the lower cylinder. with the interposition of the belts and the fibres which are being worked.
  • Figure 1 shows in section on the line I-I of Figure 2 a draft mechanism of ajoining and drawing bench called a drawing frame composed of four pairs of cylinders and end- 4 less belts.
  • Figure 2 shows the same mechanism in section on the line II--II of Figure 1.
  • Figure 3 shows in section on the line II I III of Figure 4 a draft mechanism of a slabbing frame with four pairs of cylinders, and endless belts.
  • Figure 4 shows the same mechanism in lan.
  • p In Figures 1 and 2 is shown a draft mechanism with four pairs of cylinders, in which the cylinders 12 carry the belts 34, which 1 retain the fibres and carry them to the front or drawing pair of cylinders 12.
  • At the back part of the mechanism there are two other pairs of cylinders 13-14,between which is effected the preliminar draft to diminish the twist of the sliver.
  • the cylinders 12 have at both sides of the endless belts and forming part with the said cylinders, the toothed wheels 11 and 21 whose ratio of engagement corresponds to the respective diameters of the cylindersl and 2. In this wa it is possible to transmit movement exact y to the cylinder 2 without any displacement taking place relatively'in the two belts, although the pressure exerted on the neck of the cylinder 2 is a minimum.
  • This mechanism also presents peculiarities of construction of the support 6 in which are carried the endless belts, owing to its extra width.
  • the side plates 63 of this support which are of normal type, are connected by bolts 64 to thick foundation plates 62 which are held firmly by means of a cross bar 61 inserted in them under pressure with its ends.
  • the plates 63 have edges 631 to guide the lower belt and avoid this folding over its edges downwards when moving sideways.
  • the end spindles 22 of the cylinder 2 are carried in bushes 5 which in turn are carried in the shaft supports of the drawingmechanism by means of fiat parts52 which impede their rotation. These bushes have necks or recess parts 51 over which are fitted the bars giving pressure to .the cylinders.
  • the mechanism of Figures 3 and 4 is similar to that of Figu i'es 1 and 2, and also comprises a pair of, cylinders 1 and 2 carrying the belts 3 and 4'between the plates of the support 6, and these belts supply the fibres to the front drawing cylinders 12 through the floating reducer 8 of known construction.
  • the cylinders engage together through the toothed crowns 11 and 21, the diameters of which are proportional to the diameters of the eriphery-of the cylinders 1 and 2 which wor z with the endless belts 3 and 4.
  • the pressure exerted be tween the cylinders 1 and 2 may be very light and only sufficient for the purpose of holding the slivers properly between the belts 3 and 4.
  • a high draft mechanism having endless belts to conduct the sliver to the drawing cylinders, a pair of cylinders to drive said endless belts, pressure means acting on the upper cylinder of said pair of cylinders to exert upon the belts a very light pressure in itself insuflicient to insure the motion of the belts, intermeshing toothed wheels mounted on said pair of cylinders topositively transmit motion from the lower cylinder to the upper one and thus insure a proper motion of the belts ir; respective of the light pressure therebetween.
