Definitions

  • ABSTRACT Simultaneous production of a large number of winding packages of filaments of flat, round or profiled cross section by apparatus including extrusion devices, at least one cooling device, guide means, after-treatment devices (stretching, heating, etc.) and winding devices.
  • the thermoplastic material to be processed for example a polyamide, a polyester, polyethylene or polypropylene, is melted in the extruder. Then it is, directly or by means of a metering pump, fed to the extrusion nozzle.
  • the invention provides an annular or beam-type spinning apparatus having a plurality of spinning nozzles, as well as metering devices therefor, a cooling device or shaft for the extrusions, and also extrusion-deflection devices with the best possible space utilization for the large number of individual extrusions obtained from a melt.
  • the aftertreatment devices such as guide rollers, draw-off mechanisms, heating devices, stretching mechanisms and winding devices are arranged contiguous to the devices serving for the extrusion of those structures. Each is allocated to certain, definite profile strands or bundles of profile strands.
  • all the profile strands generated in such an installation have an equal running time between their respective extrusions and their respective stretchings in the installation, independently of the distance between extrusion nozzle and stretching device. It is proposed, therefore, that between the parts which are allocated to all or at least to a large number of strands, and the subsequent parts, running times be provided by such dimensioning that the length of all the running paths is approximately equal regardless of the arrangement and the relative places of the after-treatment devices.
  • These running time intervals are advantageously formed by corresponding deflection devices, over which the profile strands are conducted in respective loops wherein, the nearer the after-treatment devices are to the units common to all the profile strands, the greater length is the loop.
  • the proposed single-stage installations make it expedient, for example, in the production of tying yarns, cords, thread or fiber bundles, to include still further devices, for example, twisting devices, texturizing devices or the like in the installation.
  • This saves still another working operation in the production of strandform or ribbon-type structures.
  • a twist-winding device preferably a ring-twist winding device.
  • a texturizing device for example, curling mechanisms consisting of two gear wheels, a false-twist device or the like.
  • FIG. 1 is a schematic view of an installation according to the invention for the production of a large number of individually stretched monocomponent profile strands;
  • FIG. 2 is a schematic view of an installation corresponding to FIG. 1, in which, for the curling of the individually stretched profile strands, there is provided a gear wheel curling mechanism;
  • FIG. 3 represents a schematic view of an installation according to the invention, in which at the outlet side of the individual stretching mechanisms there is provided in each case a twist winding device;
  • FIG. 4 is a schematic view of an alternative form of cooling shaft.
  • FIG. 1 there is represented, first of all, an extruder 1, which serves for the melting of the thermoplastic to be extruded.
  • the plastic is fed to the extruder via the filling funnel 2, and leaves it in a molten and possibly also degassed state through the discharge unit 3.
  • the discharge unit 3 is connected by a melt line 4 withone or more conveyance and metering pumps 5. Depending on the performance capacity of the extruder, it is possible to supply with one machine several pumps, so that the formation of the melt line 4 and the number of branches will differ from case to case. i
  • the conveyance and metering pumps 5 can in each case be connected over a special melt line 6 with the beam-type or annular nozzle unit 7. As a rule, however, the pumps will be joined with the unit 7 allocated in each case into one structural unit, so that the melt line 6 does not appear externally.
  • the unit 7 there are arranged several nozzles in arbitrary arrangement, for example, in several rows next to one another.
  • the nozzles are supplied as uniformly as possible with melt, so that from them there emerge numerous individual extrusion profiles 8, 8a, 8b, 8c, etc. They are conducted through as short as possible a cooling shaft 9.
  • the cooling shaft 9 consists in the simplest case of two parallel walls which have between them the extrusion melt paths.
  • the moistening device 12 consists, in a known manner, of a roller or shaft 13, which, for example, can be made of dull-chromed steel or of sintered ceramic material.
  • the roller 13 can be set in slow rotation by a mechanism not represented. It rotates with its lower part in a liquid trough 14, in which there is situated the moistening and finishing fluid.
  • two contact pressure rollers or bars 15 and 16 which for example, can be made of steel or abrasion-proof ceramic material.
  • the last contact pressure means 16 in running direction of the profile strands serves simultaneously for the deflection for the bundle 8, whose individual profile strands are now solidified to such a degree that they withstand without difficulty the deflection from the vertical into the horizontal.
  • the strand bundle is then conducted over further deflection devices 17 and 18 and then subdivided into suitable bundles of individual profile strands.
  • the endless ribbon-type profile strands are first generated in a vertical downward direction and, after sufficient cooling, are deflected with the aid of deflection devices 16, 17 and 18 from the vertical into the horizontal and finally back into the vertical.
  • deflection devices 16, 17 and 18 are deflected with the aid of deflection devices 16, 17 and 18 from the vertical into the horizontal and finally back into the vertical.
  • the after-treatment devices are arranged in more or less the same horizontal plane with the cooling shaft, or far above or below.
  • Another part 8a of the profile strands is separated out with the aid of the deflecting device 19a and 20a and supplied to the aftertreatment device 21a.
  • a further part 8b of the profile strands is separated out by the deflecting device 19b and 20b and supplied to the after-treatment device 21b, and finally a remaining part 8c is separated out through the deflecting devices 19c and 200 and supplied to the after-treatment device 210.
  • the deflecting devices belonging together in each case are disposed at such a distance from one another that the total path lengths in all the strand trains of the system are equal or at least approximately equal.
  • the after-treatment devices are arranged adjacently, preferably sideby-side.
  • the individual after-treatment devices have to be constructed at a different distance from the production assembly. If the ribbon-type profile strands were directly supplied to the after-treatment devices, then the path length and thereby the running time that the individual strand or the ground of individual strands undergoes in the after-treatment device 21 would be shorter than that in the other devices 21a, 21b, etc. In order to compensate this, through the deflecting devices 19-190 and 20-200, there have been created running paths of substantially uniform lengths between deflection device 18 and devices 21-210, which balance out the differences mentioned.
  • the after-treatment devices 21-210 are stretching mechanisms.
  • Each of the stretching mechanisms consists, in known manner, of godets 22-22c and 23-23c, to which, in each case, there may be allocated in addition a deflecting roller 24-240 and 25-25c.
  • the profile strand to be treated is wound in each case, and, if need be, several times, around the godet 22-220 as well as its deflection roller so that in this manner there is achieved an adequate friction.
  • the profile strand is then conducted onward over a heating device 31-310 to the godet 23-230 and also wound several times around it as well as around the deflecting roller 25-250. Finally the profile strands are conducted onward to the winding device 26-260.
  • the heating device is, in the embodiment illustrated, an
  • FIG. 1 makes clear the advantages of the arrangement according to the invention.
  • the compact construction as well as the splitting up according to the invention of the entire profile bundle 8-8c into a large number of adjacently arranged individual after-treatment paths there has been created a pronouncedly simple installation, whose critical parts are easily accessible during the operation.
  • FIG. 2 the numbering is carried out in the same manner as in FIG. 1.
  • the parts correspond essentially to one another; there it is merely shown that the aftertreatment devices 21-210 can be followed by still further treatment devices.
  • a two-gearwheel curling device which is represented in each case at 27, 27a, 27b and 270.
  • the arrangement of such after-treatment devices is subject to the well-known variations which are available to skilled workers in the field.
  • FIG. 3 there is represented another form of execution of the arrangement according to the invention.
  • two extruders 1 and 1a with in each case separate filling hoppers 2 and 2a, as well as corresponding melt-discharge units 3 and 3a for the molten thermoplastic.
  • the two extruder melt-discharge units are connected over lines 4 and 4a with separate pumps 5 and 5a and from there connected over melt lines 6 and 6a with the common nozzle unit 7.
  • separate conveyance and metering pumps 5 and 5a there can, of course, be used double pumps, as is known per se.
  • the two plastic streams are fed in a known manner to the profile-forming nozzle openings and there united into a bicomponent strand.
  • the other parts shown in the drawing correspond to those of FIG. 1, so that they are also provided with the same reference numbers.
  • the monofile or multifile ribbon formations are conducted to the guide eyes 32-320, from where they pass to ringtwist windings devices 28-280, in themselves known. There they are twisted or twined in a known manner and wound into cops 29-290.
  • the ring-twist winding devices are arranged in a known manner on a common rail or bench 30, which can be moved up and down in rhythm for example hydraulically. These details of the device, however, are not represented in the drawing, since they are not per se the substance of the invention.
  • the strands 8-80 in the arrangement shown in FIG. 3 are conducted in each case directly from 18, i.e., without path-length compensation via loop formation, to the rollers 20-200 of the after-treatment devices.
  • the loop formation represented in the embodiments of FIGS. 1 and 2, and conversely.
  • the freshly extruded profile strands are cooled only to such an extent that they stick together at least in places, and then yield an irregular net-type structure. This can be directly achieved by corresponding shortening of the cooling shaft to, for example, 0.5 to 0.7 m in length.
  • the freshly generated profile strand bundle after passing the cooling shaft can also be deflected in such a way that, for the purpose of final fixing, it runs in opposite direction again through the cooling shaft. This is represented in FIG. 4, where the downwardly running strand bundle 8-8c is deflected at roller 32 and then is conducted back upward in the shaft 9 and exits over the roller 33.
  • An arrangement for the simultaneous production of a large number of endless bundled profile strands of flat, round or profiled cross section of thermoplastic materials which comprises an extrusion press having an extrusion nozzle unit for simultaneously extruding a plurality of said profile strands perpendicularly downwardly, a cooling shaft therebelow with means for running extruded strands downwardly and then upwardly through the shaft, said means including at least one deflecting device for the deflecting of the downwardly running, cooled profile strands into the upward running direction, at least one further deflecting device for the deflecting of the profile strands into the approximately horizontal on a higher plane, a space saving arrangement of a plurality of said after-treatment means with contiguous paths for individual strands or sub-groups of said strands, said means including a large number of adjacently arranged, strandprocessing units allocated in each case to a strand or bundle of profile strands, each of which unitsincludes at, least a draw-off mechanism, a heating device
