Definitions

  • This invention relates to improvements in machines for spinning artificial silk, and particularly to those employing centrifuges and intended for carrying out the cuprammonium 5 stretch spinning process.
  • the spinning devices and spinning baths are arranged in front of the machine,
  • the object of the present invention is to provide a machine which is suitable for the requirements above-mentioned.
  • a machine for spinning artificial silk by the cuprammonium stretch spinning process and employing centrifuges is provided with spinning' devices arranged in an easily accessible manner on one side" of the machine, whilst the rollers for guiding, drawing-oil and stretching the threads and the spinning centrifuges are disposed on ,the other side.
  • the threads arethus; conducted from one side of the ma chine to: the other.
  • the usualacidifying devices may be disposed between the spinning devices and the centrifuges, as well as a pair of drawing ofl rollers which give the required. direction of travel to the threads. Both of these rollers may be allowed to run at once at the same peripheral speed in order to ensurethat the thread isboth drawn off uniformly and against an increased tension.
  • the roller which actually guides thethread to the centrifuge may, however, also be a1- lowed to run more quickly than the first roller in order to give av further additional stretch to the thread on'its way from the first to tl iesec'ond rollers.
  • the rollers may also be arranged'at an angle to one another so. that the machine may be constructed more compactly, and in this nr'annerthe stretching of theitliread in a transverse direction isredanced.
  • Ar guiding device may.
  • the spinning apparatus in order to conduct the thread into-an acid bath from which the; thread passes on to the drawing-off and stretching rollers, the latter being adapted to conduct the thread in a substantially vertical direction into the centre of the centrifuge lying below; If desired, the first drawing-off roller may rotate directly in the acid bath.
  • One form of construction is illustrated by way of eX-amplein the accompanying drawing wherein the figure shows diagrammatically in end elevation the most important individual parts of a machine in accordance with the invention. 7
  • the freshly spun thread is conducted from the spinning apparatus 1 to the guide rod 2 and then passes to the acid bath3. It is then seized by the drawing-off roller 4 which imparts to it the necessary tension for stretching.
  • the thread is then led further over the drawing roller 5 disposed above and which conducts it further, or again tensions and stretches it, the roller 5 being so arranged that the thread is conducted vertically I00 through the leading-in funnel 6 on the spinning centrifuge 7.
  • the rollers 4 and 5 are driven at an adjustable speed.
  • the fact that the axis of the roller 5 is arranged vertically to the axis of the roller 4 avoids the necessity to arrange the centrifuges farther outside a distance equal to the diameter of the roller 5.
  • the stretching of the threads is completed. If, however, the threadsare plastic enough, the stretching may be also still continued behind the roller 4:, and for this purpose the rollers 5 would be allowed to run faster than the rollers 4.
  • the advantage of the machine constructed in accordance with the invention consists in the fact that it presents easy accessibility to the important individual parts.
  • the spinning apparatus may be observed and attended to easily on the one side, while the spinning centrifuges and their driving devices are also particularly easy of access on the other side.
  • the handling of the drawing-off rollers is also facilitated as well as the imposing of the threads on and cleaning of the rollers.
  • a machine for spinning artificial silk by the cuprammonium stretch-spinning process comprising a spinning frame havlng spinning apparatus arranged on one side thereof,
  • a leading and draw-off roller, a leading and stretching roller, and a collecting means associated with said spinning apparatus and positioned on the side of the said spinning frame opposite to that side where, said spinning apparatus is positioned, said two rollers being arranged one above the other in a vertical I plane parallel to the length of the said spinning frame, and adapted to rotate in planes perpendicular to one another.
