Definitions
- This invention relates to a process of making spun threads from textile fibers, wherein the loosely supplied fibers are twisted together before a delivery station, in which the thread which has formed is held against twisting.
- the invention relates also to an apparatus for carrying out the process.
- This object is accomplished in the process according to the invention in that the fibers are moved in the longitudinal direction of the thread before the delivery station and during that movement are twisted together between at least two surfaces, which are in frictional contact with the outermost fibers and transversely to the longitudinal direction of the fibers, are moved relative to each other and, if desired, in mutually opposing directions.
- the invention thus makes use of the fact that a fibrous strand can be twisted together or spun between two surfaces moving relative to each other, provided that the moving surfaces are succeeded by a delivery station, in which the fibrous strand is withdrawn continuously in a direction which is transverse to the direction of movement of the surfaces but prevents a rotation of the fibrous strand.
- the process can be carried out in a simple manner and at very high-spinning speeds.
- This process can be practiced in a particularly desirable manner if the loose fibers are supplied to a smooth trough, which has a depth which is smaller than the diameter of the strand and which forms a stationary guide and one of said surfaces whereas the second surface is moved continuously over the trough transversely thereto and to the longitudinal direction of the strand.
- the fibers are blown by a directed air stream to a guide or into the trough in the longitudinal direction thereof.
- An apparatus for carrying out the process according to the invention is essentially characterized by a table, which is provided with at least one trough and preferably with a multiplicity of parallel troughs disposed one beside another, an endless belt extending transversely to the troughs and revolving over said table, and at least one pair of delivery rolls or the like succeeding the table.
- the surface which is continuously moved transversely to the troughs is thus formed by a revolving endless belt.
- This arrangement is very simple in structure and has the advantage that such endless belt is sufficient for a multiplicity of troughs and for a multiplicity of threads to be formed and the fibers can be twisted together at high speeds because the threads are very small in diameter and the belt may move at speeds which can be controlled well whereas high spinning speeds can be produced in that the thin thread rolls in contact with the belt moving thereover.
- the trough tapers in depth and width toward the delivery rolls or the like in order to ensure that the loosely supplied fibers will be properly condensed.
- the table is preferably preceded by a common carding drum, which extends transversely to the troughs and is provided with an inlet device and on multiplicity of threads.
- the process according to the invention may be carried out alternatively by an apparatus which comprises a circular table having radial grooves, and a central station for delivering threads, and a disc which is coaxially disposed over the table and about the same size as the latter and forms the surface which is moved transversely to the troughs.
- an apparatus which comprises a circular table having radial grooves, and a central station for delivering threads, and a disc which is coaxially disposed over the table and about the same size as the latter and forms the surface which is moved transversely to the troughs.
- a single apparatus which is relatively simple, may be used to make a multiplicity of spun threads.
- the speed of the disc in this case may be only a small fraction of the speed of the elements which have been used before for a twisting together or spinning of strands.
- the process according to the invention may be carried out by an apparatus which comprises two parallel endless belts, which are disposed one over the other and revolve in the same direction and with their confronting courses form two surfaces, which are moved relative to each other transversely to the longitudinal direction of the thread and serve to twist at least one strand which is pulled through between them and which moves through a funnel disposed on one longitudinal side and through an eye or the like disposed on the other longitudinal side of the endless belts, which eye or the like is succeeded by a pair of delivery rolls or the like. Because the endless belts revolve in the same sense, the two confronting courses of the belts move in mutually opposite directions so that the fibers are twisted together as between the palms of two hands.
- FIG. 1 is a perspective view showing the essential parts of an apparatus for carrying out the process according to the invention
- FIGS. 2 and 3 are, respectively, a longitudinal sectional view and a transverse sectional view taken on line III-Ill in FIG. 2 and showing diagrammatically an apparatus as shown in FIG. 1.
- FIGS. 4 and 5, respectively, are also longitudinal and transverse sectional views showing diagrammatically another apparatus.
- FIG. 1 It is apparent from FIG. 1 that loose fibers are supplied to a smooth trough 1, the depth of which is smaller than the diameter of the thread.
- a surface 2 is continuously moved over the trough ll transversely to the longitudinal direction of the trough or thread. The surface 2 is in frictional contact with the uppermost fibers of the trough.
- the trough l is terminated before a pair of delivery rolls 3, which continuously withdraw the thread which has been formed but hold the thread against rotation so that the fibers in the trough are actually twisted together as a result of the transverse movement of the surface 2, particularly because before that surface the fiber material is loose and free to twist.
- a table 4 if formed with a multiplicity of parallel troughs 1 extending one beside the other and in succeeded by delivery rolls 3.
- the troughs 1 taper toward the delivery rolls.
- the surface 2 moving transversely to the grooves is formed by a revolving endless belt.
- the table 4 is preceded by a common carding drum 5, which extends transversely to the troughs and is provided with an inlet unit 6.
- the carding drum 5 turns upwardly.
- the carding drum 5 is set with pins or teeth and disintegrates the fiber material into individual fibers. The fiber material is supplied to the drum throughout the width thereof.
- Air nozzles 8 are associated with respective troughs 1 and open into the drum housing 7 under the carding drum.
- the nozzles 8 extend in the direction of the trough and approximately tangentially to the carding drum.
- the directed air streams extending from the nozzles 8 entrain the individual fibers and carry the into the troughs 1, which between the carding drum and the endless belt 2 are provided with a perforated cover 9, through which the air can escape.
- the thread which has been made can then be wound up in any desired manner behind the delivery rolls 3.
- the apparatus consists of two parallel endless belts 2, 2a, which are disposed one over the other and revolve in opposite sense so that their confronting courses form two surfaces moving in mutually opposite directions. Between these surfaces, a plurality of strands move in parallel transverse directions.
- a strand guide is provided, which consists of a funnel 10 on one longitudinal side and an eye 11 on the other longitudinal side of the two endless belts 2.
- the eye 11 is succeeded by the pair of delivery rolls 3.
- the loose fibers are blown into the guide funnel 10, e.g., by a unit which is like that shown in FIG. 2.
- a cord or the like is pulled through between the delivery rolls 3 and through the eye 11 and the funnel 10.
- a process of making a spun thread from textile fibers comprising the steps of l. delivering loose and freely movable textile fibers to a spinning station,
- Apparatus for making spun threads from textile fibers which apparatus comprises a table which is formed with a trough defined by a first surface and adapted to receive a strand of loose fibers,
- a revolvable endless belt having a course extending transversely to said trough, said course having a lower surface which forms a second surface disposed closely above said trough, said belt being revolvable to move said second surface relative to said first surface transversely to the longitudinal direction of said trough,
- delivery means operable to withdraw said thread from said trough while holding said thread against rotation.
- each of said troughs is defined by a first surface and adapted to receive a strand of loose fibers
- said second surface is disposed closely above all said troughs
- said belt is revolvable to move said second surface relative to all said first surfaces transversely to the longitudinal direction of said troughs, whereby each of said strands is frictionally contacted with one of said first surfaces and said second surface and twisted to form a thread
- said delivery means are operable to withdraw all said threads from said troughs while holding said threads against rotation.
