Definitions

  • the present invention relates to a process of heating spinning cells or shafts for spinning artificial threads according to the dry spinning process and to a device for per- .l forming the said process.
  • the heating of the spinning cells is effected by circulating a current of a heating medium in such a manner that it comes in contact successively with the upper part of each of the spinning cells and circulating a second current of the heating medium in such a manner that it comes in contact successively with the lower part of the spinning cells.
  • the said currents of the heating medium are circulating separately from each other, care being taken,
  • a number of spinning cells the heating of the upper and lower ends oi each being eii'ected separately by means of a heating medium circulating in jackets surrounding the spinning cells is united to form an aggregate.
  • a certain number of the jackets, surrounding the spinning cells are connected with each other by means of tubes, as to form two or more series, for instance, the total number of the spinning cells may be halved.
  • the heating fluid is caused to traverse the jackets, surrounding the cells, one after the other. In this manner the heating fluid suii'ers between the first and the last cell a certain Vfall of temperature.
  • the said difference of temperature is compensated.
  • the spinning cells which in the upper system are receiving less heat in consequence of the temperature drop of the heating'fluid are the rst to be heated in the lower system and thereby receive the largest quantity of heat. Furthermore, by the division of theheating system in two systems, from which the one heats the'upper part and the other the lower part of the spinning cells, it is possible to heat Vthe different parts of the cells to different temperatures. f
  • the accompanying diagram illustrates an arrangement according to the invention.
  • a large number of similarly constructed spinning shafts is united to form an aggregate and each shaft is surrounded in the upper part by a heating jacket a and in the lower part by a heating .jacket Y).
  • the jackets a belong to the first heating system, the heating fluid in which is kept in circulation by the pump c.
  • the heating yiuid enters first into the two end jackets of the system and then Hows through one half ofthe number of jackets in series, so that the two currents ultimately meet at the intake of the pump c. To allow of this iiow the'jackets are connected by the pipes e.
  • the pump d delivers the heating Huid to the two middle jackets b and the two currents thien flow in opposite directions each through half the number of jackets in series, and finally leave the end jackets to unite at the intake of the pump.
  • a heating device not shown in the drawing, which contains vthe circulating fluid at the desired temperature.
  • An apparatus for spinning Y artificial threads according to the dry spinning methodV comprising in operative combination at least two spinning cells, the upper part as well as the lower part of each spinning cell, being provided each with a water jacket, means for connecting the upper ackets suc- 5 cessively, means for connecting the lower jackets successively, means for c1rculat1'ng a heating medium through the upper jackets and means for circulating the heating medium through the lower jackets in ODp0- site direction to that of the upper jackets.
