Definitions

  • This invention relatesto centrifugal spinning machines for the production of artificial In such machines which are already known, one row of centrifuges is associated with a row of spinning devices. Owing to'this ar-" rangement, the number of the spinning devices and the output of the machine are limit ed.
  • the object of the present invention is to provide an arrangement by means of which the output of the machine may be doubled or even increased to a greater extent.
  • a centrifugal spinning machine for the production of artificml silk is provided with a row of spinning devices in which a greater number of such devices than usual are employed, and with two or more rows of spinning centrifuges, whilst one or more rows of guide or conveying rollers or equivalent members are as sociatedwith the said spinning devices and centrifuges.
  • the guide or conveying rollers are all disposed upon a single shaft and serve to guide or stretch the threads and to conve them as vertically as possible to the centri gee the threads being passed alternatel to the of centrifuges. this case, of course, the threads are not passed into the spinning tubes or funnels actually vertically but ina somewhat slopin direction.
  • the rollers may be arranged alternately on two parallel shafts in such a manner that the threads may be conveyed to the rows of centrifuges independently of one another and in a vertical direction.
  • spinnerettes immersed in an open precipitatbath, or spinnerettes in so-called spinning t l ibes, or spinning funnels may be employed, the latter being used for carrying out the stretch spinning process.
  • the usual spinning devices may be employed in this case in association with acidifying apparatus. Particularly suitable spinning devices are described in Patent No. 1,682,7 97 ,granted 'Sept. 4, 1928.
  • each of the threads may be passed over two rollers.
  • the threads may be passed first of all over a lower row of rollers and then over a second row of rollers dis osed above the first row. In this manner, the path traversed by the threads is considerably lengthened, without having to increase the overall size of the machine.
  • All the second row of rollers may be disposed on one shaft only or they may be arranged upon two shafts, those of the first row alternating with those of the second row. In the latter case, the threads may be conveyed in a vertical direction to the centrifuges.
  • the rows of centrifuges may be arranged accurately one behind the other in such a manner that the casings which protect the centrifu es fit into each other like a chessboard. This case, it is ofadvantage under certain conditions to mount one of the upper rows of conve ing rollers upon transverse shafts so that a the threads may be conducted into the centrifuges along their axes of rotation in spite of the limited amount of space.
  • One arrangement suitable for the purpose is one in which the spinning centrifuges are arranged in rows, one behind the other and alternately to each other.' By this arrangement, the rear rows of centrifuges, and particularly the introduction of the threads into and changing the spinning pots or spinning pot linings, may be attended to more easily.
  • the casings for the centrifuges may be formed with five sides when sides'of the rows of spinning devices.
  • centrifuges may also disposed in the form of steps which slope upwards.
  • Figure 2 another form of construction of a similar machine.
  • Figures 3 and 4 each one form of construction of a stretch spinning machine in cross section.
  • Figure 5 a plan view showing the centrifuges arranged in the form of a honeycomb.
  • Figure 6 shows another form of construction of a stretch spinning machine in crosssection.
  • rollers 6 which are mounted upon a single shaft and are then conveyed alternately through the funnel tubes 7 and 7 to the centrifuges 8 and 8, the latter being surrounded by protecting casings 9 and 9.
  • FIG 4 which illustrates a machine for the same kind of artificial silk spinning process
  • the threads pass from the acidifying apparatus 5 and then over the row of rollers 10 to the rows of rollers 6 and 6, these latter being arranged above the rollers 10.
  • Each roller 6 is mounted upon a transverse shaft so as to permit the direction of. the threads to be changed transversely to the plane of travel of the threadsso that the threads may be passed vertically into the funnel tubes 7 of the first row of centrifuges 8.
  • a centrifugal spinning machine for the production of artificial silk having one row of spinning nozzles in which a greater number of such nozzles than usual for a given length of machine are employed, a plurality of rows 'of spinning centrifuges in- .cluding a centrifugefor.each spinning noz-- zle, two upper rows of conducting members and a lower row of conducting members for the threads associated with the spinning nozzles and centrifuges, said u per conducting members being so arranged that threads from adjacent spinning nozzles may be conducted substantially vertically into the centrifuges of different rows.
  • a centrifugal spinning machine for the production of artificial silk having one row of spinning nozzles, in which a greater number of such nozzles than usual for a given length of machine are employed, a plurality of rows of spinning centrifuges including a centrifuge for each spinning nozzle, a lower row of conducting members, a row of shafts,
  • a shaft disposed substantially at right angles to the shafts forming the row of shafts, a pair of upper rows of conducting members, the conducting members of one of said rows being-mounted upon the shaft, each of the conducting members of the other row being mounted upon one of the shafts of the row of shafts, said conducting members bein so arranged'that threads from adjacent spinning nozzles may be conducted to centrifuges in different rows.
  • centrifugal inning machine for the production of artificial silk having one row of spinning nozzles in whic a greater num- .ber of such nozzles for a given length of machine are employed, a pair of rows of spinning centrifuges including a centrifuge for each spinning nozzle, the centrifuges in one nemesis conducting members being so arranged that September, 11928.
  • threads from adjacent spinning nozzles may be conducted to centrifuges in difierent rows.
  • a centrifugal spinning machine for the production of artificial silk having a single row' of spinning tunnels, means for hardening the freshly spun threads, a plurality of rows of spinning centrifuges arranged on one side oi the machine, the total number of said centrifuges corresponding with the nanoher at the spinning tunnels, and two draw ing rollers associated with each i nmel for conveying the thread from the spinning inn nels to the centrifuges, one of said drawing rollers heing positioned at the level of the thread leaving the hardening means and the other heing positioned at a greater eleva tion, said drawing rollers heing so arranged threads from adjacent nozzles may he conducted to centrifuges in diderent rows,
