Definitions

  • the invention has as its object to provide a drawing system for parallelizing and drawing textile fibres of every type and quality (animal, vegetable, artificial, synthetic, mixed or unmixed), said device to be used for the drawing operation preceding the spinning operation proper, instead of actual known drawing systems such as drawing frames with porcupine-rollers, gill-boxes, screw-gills with fallers, gill-boxes with double set of fallers etc.
  • the invention also has as its object to provide a drawing system free from the disadvantages of drawing systents having screws and fallers, gill-boxes, said disadvantages being, amongst other things, a maximum speed of the fallers sets limited to 6 to 7 metres, high cost of construction, rapid wear of the members due to the jerky movement of the fallers or needles-bars, noisy operation, considerable maintenance or the like.
  • the subject of the invention is a drawing system for textile fibres of the type which comprises, between the pair of feeding cylinders and the pair of drawing cylinders, a lower set of circular combs or porcupine rollers and an upper set of circular combs or porcupine rollers, in combination, the said system being characterized in that the needles of the upper porcupine rollers intermesh with the needles of preceding and succeeding rollers in the upper set and that the needles of the lower rollers likewise intermesh with the needles of preceding and succeeding rollers in the lower set.
  • Figure l is a schematic side elevation view of an intersecting drawing system having porcupine rollers
  • Figs. 2, 3, 4 and are fragmentary schematic side elevations showing modifications
  • Fig. 6 is a plan partially in section approximately on the line VI-VI in Fig. 1, and
  • Fig. 7 is an enlarged fragmentary plan of three of the porcupine rollers shown in Fig. 5.
  • 1 and 2 designate the feeding cylinders and 3 and 4 designate a pair of drawing cylinders having a common pressure cylinder 5.
  • the upper set is formed by a plurality of porcupine rollers 7 and is pivotable, which enables it to be opened laterally up to 95 both while in operation and While at rest.
  • the disposition of the double drawing cylinders 3 and ice 2 4 enables same to approach to about 22 mm. from the nipping point at the egress of the needles of the last pair of porcupine rollers 6 and 7, it being possible to reduce this distance still further, as illustrated in Figure 2, by the addition of a pair of rollers 8 and 9 which serve to confine the fibres in the space between the porcupine rollers 6 and 7 and the drawing cylinders 3 and 5 and also they remove any static electricity that may have been generated by the frictional sliding of the fibres during the drawing operation.
  • the additional rollers 8 and 9' are particularly useful for drawing short fibres.
  • sliver 15 is a de-electrifying device arranged after the drawing system 3, 4, 5 at the egress of the sliver 15 on its way to a canner or beamer.
  • 11 and 12 are automatic electric anti-tufting stop devices, and 13 and 14 are circular brushes which keep the porcupine rollers clean.
  • This intersecting drawing system having porcupine rollers formed according to the invention has many advantages amongst which are: increased speed which, from the mechanical point of view, is almost unlimited and the maximum of which is dependent upon the nature of the fibres being worked, for example, an inlet speed of 30 to 35 metres: being possible with wool, this resulting in a substantial increase in production; simplified construction and therefore reduced cost price; less driving energy for a given output; easy maintenance, less lubricating of a number of members; self-stripping and, consequently, fewer stoppages for cleaning, and a working-up that is more constantly clean than with the fallers; noiseless running.
  • porcupines 6 and 7 of the lower and upper sets may be employed according to the arrangements: illustrated in Figures 3, 4 and 5, in which:
  • the centres A, B, C and D form an equiangular and equilateral square, the porcupinerollers A, C having identical steel pinning or studding and B, D having a studding which is offset in order to ensure penetration.
  • a drawing system for a sliver of textile fibres comprising a pair of feeding rolls, a pair of drawing rolls, said sliver traveling in a substantially straight line from said feeding rolls to said drawing rolls, a plurality of procupine rollers having projecting needles and comprising a set of at least two porcupine rollers above the sliver and a corresponding set of porcupine rollers below the sliver, the needles of each porcupine roller of the upper set overlapping and intermeshing with the needles of the corresponding porcupine roller of the lower set and the needles of successive porcupine rollers in each of said sets overlapping and intermeshing with the needles of adjacent porcupine rollers in the same set the overlapping of the B, C and D form a paralleloneedles of said rollers being such that the zone of intermeshing of each of said lower rollers with an associated upper roller extends substantially to the zone of intermeshing of the next adjacent lower roller with an associated upper roller so as to subject a sliver to
  • a drawing system in which the needles of certain porcupine rollers of one set inter-mesh with the needles of two rollers of the other set.
  • a drawing system in which a pair of de-electrifying and confining rollers is disposed between said porcupine rollers and said drawing rolls in position to engage the sliver.
  • a drawing system for a sliver of textile fibres comprising a pair of feeding rolls, a pair of drawing rolls, said sliver traveling in a substantially straight line from said feeding rolls to said drawing rolls, a plurality of porcupine rollers between said feeding rolls and drawing rolls, each of said porcupine rollers comprising a cylinder and a multiplicity of flexible needles projecting from said cylinder, the circle defined by the tips of said needles being herein termed the needle circle, said porcupine rollers comprising an upper set of rollers'disposed above the sliver and a lower set of rollers disposed below the sliver, said rollers being so disposed that the needle circle of each porcupine roller of said upper set intersects and overlaps the needle circle of a corresponding roller of the lower set and the needle circles of the porcupine rollers of each of saidsets intersect and overlap the needle circles of preceding and succeeding porcupine rollers in the same set by an amount approximately equal to half the radii of said needle circles so as to subject
