Definitions

  • melt-conducting conduits of the melt distributor system and the spinning heads are encased or lined by a common vapor generator for heating with diphenyl vapor or the like, this generator having a connected vapor distributor and condensate collecting conduit system extending from the screw to the common vapor generator and also from the generator to each spinning head to heat the same.
  • melt-spinning apparatus for producing filaments
  • the melt distributor conduit system and the vapor distributor for heating the spinning heads as well as the condensate collecting system are all arranged separately.
  • the melt-conducting device i.e., a screw extruder or a pump
  • the melt distributor conduits or lines are arranged above the spinning heads and the melt distributor lines are connected to the top of the spinning heads.
  • the condensate reflux lines and usually also the vapor-conducting lines are arranged underneath the spinning heads and are connected from below with the spinning heads.
  • the vaporgenerating assembly is mounted so as to be spatially separate from the spinning apparatus.
  • meltconducting line for the diphenyl or other heat transfer agent can be directed to a central melt distributor line. Proceeding from this central line, the meltconducting lines are heated, all these melt lines each being surrounded by a mantle or tubular jacket with spacing to provide an annular passage through which the diphenyl vapor can be conducted as the heat transfer medium.
  • an improved spinning apparatus or assembly for producing melt-spun filaments, bands or the like by the combination which comprises a plurality of spinning units including a series of individual spinning heads arranged in a row; a single extruder or pump means for supplying polymer melt to said spinning heads, a melt distributor system of conduits interconnecting said extruder or pump means with said spinning heads for distribution of the melt to each of the spinning heads, and a second fluid distributor system for a vaporous heating agent including a common jacketing means encasing the conduits of the melt distributor system, at least part of said jacketing means being positioned below the level of said spinning heads.
  • the jacketing means is preferably an elongated vessel mounted or arranged below the level of the spinning heads so as to receive the individual melt-conducting conduits from the corresponding individual spinning heads as well as the supply conduit from the extruder or pump means within a common enclosure for the vaporous heating agent. Individual vapor lines connected to the vessel then extend outwardly and upwardly so as to surround and accompany the corresponding individual melt conduits leading to each of the spinning heads.
  • the condensate thus can return by gravity flow into the elongated vessel where it can be heated and revaporized or where it can be further conducted to a reboiler or the like preferably located below the vapor distributing vessel.
  • FIG. 1 is a partly schematic perspective view of the entire spinning assembly arranged in accordance with one embodiment of the invention
  • FIG. 2 is a schematic end view of the central elongated vessel serving as vapor distributor, condensate collector and vapor generator;
  • FIG. 3 is another schematic end view of the elongated vessel to illustrate an embodiment in which the vapor generator is spatially separated from the vapor distributor.
  • the spinning assembly is constructed around a central elongated vessel or enclosed tubular member 1 having a plurality of tap lines or distribution conduits 2a, 2b, 20, etc. directed diagonally upwardly to a relatively large number of spinning heads 3a, 3b, 30, etc., arranged in a row along a substantially horizontal plane.
  • the vessel or tube 1 is preferably situated with its longitudinal axis approximately parallel to the horizontal plane or a central line drawn through the series of spinning heads and is also located laterally and at least partly below the level of the spinning heads.
  • This vessel 1 can then be partly filled with a vaporous heating agent such as diphenyl or the like, as indicated in FIG. 2, and equipped with any suitable heating means 12 to vaporize the liquid diphenyl.
  • This heating means may be electrical as with heating bands or other resistance heaters or may also be accomplished with other conventional direct or indirect heating devices.
  • the vessel 1 as shown in FIGS. 1 and 2 with its conduits 2a, 2b, 2c and 4 acts as a complete system for the generation and distribution of the heating vapor and also for the collection of condensate.
  • these elements constitute a common jacketing means encasing the melt distributor system which essentially includes the three branched conduits 5a, 5b and 50 extending to their respective spinning heads and the melt supply conduit or main feed line 6 issuing from the outlet end of the screw extruder 7.
  • Each of the melt distributing lines 50, 5b and 5c are preferably of the same length so as to maintain a common temperature control in relation to the residence time of the melt in the distribution system.
  • the screw extruder 7 with its drive means 8 is likewise preferably mounted laterally underneath the spinning heads 3a, 3b and 3c, i.e., to one side of the row of spinning heads so as to be approximately parallel thereto as well as being parallel to the vessel 1.
  • the encasing conduit 4 around melt supply conduit 6 is preferably also directed slightly upwardly from the vessel l to its connection at the end of the extruder 7.
  • the extruder 7 may be replaced by a conventional pump, e.g., to conduct the polymer melt from a single large extruder which supplies an even larger number of spinning heads.
  • a conventional pump e.g., to conduct the polymer melt from a single large extruder which supplies an even larger number of spinning heads.
  • the condensate return lines are identical with the vapor distribution conduits 2a, 2b, 2c and 4 which form an annular space around the melt conduits 5a, 5b, 5c and 6, respectively. It is also feasible, however, to provide separate return lines for the condensate, including separate lines withdrawing condensate from within the spinning heads and/or from an extruder or pump means which is more advantageously arranged in such a manner that a gravity flow return of the condensate is not possible.
  • the common vapor distribution and condensate collection system does represent a significant advantage where a gravity flow return of the condensate is ensured by the positioning of the vessel 1 or at least part of the common jacketing means below the level of the spinning heads.
  • Means for mounting or supporting all of the individual elements or members of the spinning apparatus have been omitted in the drawing since one can readily construct a suitable framework or provide floor and wall arrangements to receive the assembled structure. It is of special advantage that all of the parts can be mounted on supporting means after being formed of structural units mountable in prefinished form and being transportable as a unitary spinning installation.
  • the vessel 1 serves only as a distribution means for the vapor and a part of the condensate collection system while the generation of the heating vapor from the continuously returned liquid condensate is carried out in the spatially separated pot or reboiler l3 equipped with a heating device 14.
  • Condensate is returned from the lowermost level of the vessel 1 through line 15 to the reboiler 13 while vapors are preferably fed upwardly through a number of feed lines 16a, 161), etc.
  • the reboiler is preferably arranged a short distance below the distribution vessel 1 and can extend longitudinally under one or many such vessels in a large commercial installation. Heating bands are then most advantageous as the means of heating the reboiler.
  • the heat or vapor distribution system simultaneously includes in itself also the melt conducting conduits, i.e., the melt feed line from the extruder and the melt distributor lines, one can achieve in a simple manner and by conventional regulating means a uniform melt temperature and, at the same time with respect to the construction, a space-saving arrangement.
  • the vapor distributing system may not directly include a vapor generating means, a spatially separate reboiler or vaporgenerating unit is provided which is directly placed in fluid connection with the jacketing means of the vapor distribution system.
  • This embodiment is also preferred when a common vapor generating unit is provided for several spinning installations.
  • a substantial advantage is to be seen in that all the essential elements or parts which form the spinning apparatus can be mounted in their final or at least preassembled state in the manufacturing plant.
  • the screw extruder with its drive means, the distributor systems containing the melt conduits and vapor jackets as well as the spinning heads with their required pumps, pump drives and blowing shafts are arranged mounted in their intended position on a carrying or transportable frame, and may even be wired and insulated so as to be ready for operation.
  • These various structural parts yield an installation which is compact in construction with a relatively small overall volume. The entire installation can be loaded into a suitably large transportation container with the aid of a suitable hoisting means or the like, and then transported to the construction site, unloaded and erected.
  • Such a spinning installation further exhibits advantages of improved free viewing of the spinning heads during their operation and free accessibility to the spinning heads for maintenance or repair.
  • Apparatus for spinning filaments, bands or the like of a molten thermoplastic polymer which comprises:
  • a plurality of spinning units including a series of individual spinning heads arranged in a row;
  • melt distributor system of conduits interconnecting said extruder or pump means with said spinning heads for distribution of the melt to each of the spinning heads;
  • a second fluid distributor system for a vaporous heating agent including a common jacketing means encasing the conduits of the melt distributor system, at least part of said jacketing means being formed by at least one elongated vessel arranged below the level of said spinning heads to supply vapor for heating said melt conduits and to collect the condensate being formed during said heating.
  • said jacketing means is an elongated vessel arranged below the level of said spinning heads to receive said conduits from the individual spinning heads and the extruder or pump means within a common enclosure for the vaporous heating agent, individual vapor lines being connected to said vessel to extend outwardly and upwardly together with and surrounding the corresponding individual melt conduits to each of said spinning heads.
  • Spinning apparatus as claimed in claim 2 wherein said elongated vessel arranged below the level of said spinning heads contains heating means for generating said vaporous heating agent from a liquid condensate thereof being collected in said vessel.
  • Spinning apparatus as claimed in claim 1 wherein the spinning units together with their associated metering pumps, pump drives and vertical blowing shafts are mounted on a supporting means which also carries the extruder or pump means for supplying the polymer melt and the intermediate melt-distribution and vapor distribution systems, all of the supported elements being formed of structural units mountable in prefinished form and being transportable as a unitary spinning installation.
