  The invention relates to a device in a preparation machine for spinning, in particular a drawing bench or a carding machine, in which, at the outlet, a ruhan of fibers is delivered by a distribution device and is deposited on a support. base, the distribution device and the base support being movable relatively with respect to each other, and in which the fiber ruhan deposited on the base support (ruhan package) can be brought to a

transformation placed downstream.

  In a known device (document EP 0 457 099), the fiber ribbon produced by the machine delivering the fiber ribbon (carding machine, drawing bench) is deposited in

  a spinning pot with a rectangular tranevereale section.

  In this case, the spinning pot is moved back and forth

  comes to the drop zone. After filling the pot with ribbon deposited in the form of loops or rings, the pot is transported, together with the fiber ribbon, out of the deposition zone, and is brought to a device downstream. Several filled pots are stored in an intermediate manner so as to create a buffer, then are transferred, for example, to a spinning machine. The transport of the pots between the buffer stock and the spinning machine is carried out on a transport trolley. A drawback of the device lies in the significant implementation with regard to the installation. Indeed, it is necessary to introduce a large number of pots (empty pots) into the deposition area of the machine delivering the fiber ribbon (drawing bench, carding machine), and the pots filled with fiber ribbon (pots full) must again be taken out of the drop zone. With the adaptation of the machine on the 3s plan of construction, with the pot, and with the important handling with the additional setting up for the

2 2835536

  conveying or transporting the pots, there is considerable implementation (acquisition, storage, repair and the like) for the pots themselves. Finally, the fiber ribbon must again be extracted from the pots in the downstream processing machine. Also, the object of the invention is to provide a device of the type described in the introduction, which overcomes the drawbacks mentioned, and which allows in particular in a simple manner the displacement of the ruLan of fibers (bundle of ribbon) in the deposition zone and / or its exit from the deposition zone of the machine, while ensuring a significant reduction in the implementation as regards

the installation.

  In accordance with the invention, this object is achieved by virtue of the fact that the deposited ruhan of fibers (bundle of tape) can be moved by mechanical means, which produces the displacement of the ruLan of fibers (bundle of ribbon) in the area of deposit and / or exit from the deposit area, without additional containers or similar items. As the deposited fiber ribbon (ribbon package) can be moved as such. by mechanical means, both during the deposition of the ribbon in the deposition zone, and after the deposition of the ruhan, outside the deposition zone, this results in a quite considerable simplification of the handling of the ruhan of fibers. The removal of fiber ruhans in pots or similar elements in the processing machine

  downstream, for example a spinning machine, is deleted.

  To this is added a large-scale reduction with regard to the implementation of the installation. An adaptation in terms of construction, to a pot, of the machine delivering the fiber ribbon (drawing bench,

3 2835536

  card), is not necessary. Any implementation relating to the supply, storage, repair or the like for a large number of pots is more

  particularly entirely deleted.

  Figure 1 (la, b, c) schematically shows, in side view, a high-performance drawing bench 1 (self-adjusting bench) from the company Trutzschler, Monchengladbach, for example the high-performance drawing bench of the type HSR 1000. The fiber ribbons enter, from pots not shown, in a drawing group, are drawn there and, after their exit from the drawing group, are grouped in a single fiber tape. This ruLan of fibers crosses a turntable 2 and is then deposited in the form of rings or loops on a basic support, for example a carriage 3 with rectangular upper surface 3a, moving back and forth in the direction of arrows A and B. by forming a packet of ribbon 4. The carriage 3 is driven by a drive motor 5 which can be controlled and which is connected to an electronic control and adjustment device 6, or to the control of the machine. The reference 10 designates a cover sheet for the tape dispensing device (pot head), which connects to the support plate 7. The reference F designates the direction of work (flow of movement of the fiber material) at the inside the drawing bench, while the fiber ribbon 4 is delivered by the turntable 2 substantially in the vertical direction. Mark 8 deflects the drop zone, mark 9 the area outside of drop zone 8. Drop zone 8 covers the distance of travel a according to

figure lc.

  In FIG. 1a is shown one of the extreme positions and in FIG. 1b, the other extreme position of the carriage 3 traveling horizontally back and forth in the directions A, B. during the deposition of the fiber ribbon 4. The ribbon package 4 is also moved in 2s back and forth in the direction of the arrows A, B. under the turntable 2. After having reached the extreme position shown in FIG. 1a, the carriage 3 moves in the direction arrow C, the carriage 3 being accelerated, driven with a speed remaining uniform and then braked. After reaching the extreme position shown in FIG. 1b, the carriage 3 returns in the direction of arrow D, the carriage 3 being accelerated, driven with a speed remaining uniform and then braked. The reversal of the movement of 3s back and forth is obtained by the control device 6 in combination with the drive motor 5. After

8 2835536

  having finished depositing the ribbon packet 4 on the surface 3a, the carriage 3 moves, in common with the ribbon packet 4, in the direction of the arrow E, to exit from the ribbon distribution device (pot head ). The command 6 switches the movement of the carriage 3 when passing from the reciprocating movement (arrows A, B) during the deposition of the ribbon, to the movement of

  exit (arrow E) outside the depot area 8.

  The electric motor 5 can be adjusted in speed from

  rotation, drives the carriage 3 with a speed without

  beating or practically without beating. In particular, acceleration and braking are carried out smoothly or practically smoothly. The speed between acceleration and braking is uniform. In this way, this allows the tape package 4 to remain stable, both during the reciprocating movement in the deposition zone 8 according to FIGS. 1a and 1b, as during the exit movement out of the deposit 8 according to figure lc. The movements are controlled so as to achieve the highest possible production speed, without the ribbon pack slipping,

even rocking.

  FIG. 2 shows on the drawing bench according to FIGS. 1a, b, c, that round pots 44 are arranged under the ribbon entry 45, and that the raw supply ribbons 46 are unwound via rollers and brought to the drawing group. After passing through the stretching group 11, the stretched ribbon 12 reaches the turntable 2 and is deposited in loops or rings on a rectangular plate or tray 13. The plate 13 is arranged on a conveyor belt 14 in endless revolution, which is driven by an electric motor 15 which can be controlled and ensuring the back and forth movement of the

9 2835536

  conveyor belt 14 in the direction of the arrows G. H. with the plate 13 and the ribbon packet 4. The electric motor 15 is connected to an electric unit of

command and request 6.

  FIG. 3 shows a card, for example a high-performance card of the type DK 903 from the company Trutzschler, comprising a supply cylinder 16, a supply table 17, breakers 18a, 18b, 18c, a drum 19 , a comber 20, a detaching cylinder 21, expressing cylinders 22, a sail guiding element 24, a sail hopper 25, extractor cylinders 26, a movable cap 28, and a pot head 29. The directions of rotation cylinders are indicated by curved arrows. The reference I designates the working direction of the card. Above the pot head cover plate 30, there is a housing 31 in which there is a rotating turntable 32. The basic support is produced in the form of a carriage 3 which has on its upper side, a rectangular plate or plate 30. During the deposition of the fiber ribbon 31 by the turntable 32, the carriage 3 is moved in va back and forth in the direction of the arrows K, L, by a drive device, by

2s example a motor 32 controlled.

  FIG. 4a shows a top view of the package of fiber ruhan 4 freely deposited in the form of rings or loops on the surface 3a of the carriage 3. FIG. 4b shows in side view, the package of fiber ribbon 4

2835536

  in the direction of the arrows M, N. The ruLan package 4 is placed on the upper strand 33a of the conveyor belt 33. During the deposition of the ruhan, the carriage 3 moves back and forth in the direction of the arrows C , D. After having respectively reached an extreme position (compare with FIGS. 1a, 1b), the conveyor belt 33 is moved downward in the direction M, by a value corresponding approximately to a thickness of ribbon, for example 10 mm , by a drive motor (not shown). When the deposition of fiber tape is completed, the upper strand of the conveyor belt 33a is moved by a controlled drive motor (not shown), in the direction R. so that the ruhan package 4 is slid over a surface substantially planar support 35, disposed alongside, for example a transport shell. The edge of the support surface 35, directed towards the carriage 3, is for example chamfered, rounded or of a

similar configuration.

  According to Figure 6, on the carriage 3 is disposed a lifting plate 36, for example a plate or a plate, which, in the manner known per se from the document DE 44 07 849 A1, can be mounted on elements support and be moved in the direction of the arrows OP On the carriage 3 is provided a support element 37, for example an upright, on which is mounted a pushing device 38 by means of a controlled drive element 39 suitable, such as for example a pneumatic cylinder, a screw drive or similar system. When the deposit of the ruLan package 4 on the surface of the lifting plate 36, is completed, the pushing device 38 is moved, in the direction of the arrow S. against the tape package 4, so that the tape package 4 is transferred from the lifting plate 36 to the support surface 35, by

11 2835536

  direct pushing of the ribbon packet by the pushing device 38. The support surface 35 rests on a chassis structure 40 or similar element, and can be taken in common with the ruLan packet 4 from the surface of the chassis structure 40 , to be brought to a downstream processing machine, for example a

  spinning machine, or buffer storage.

  According to FIG. 7, there is a lifting or raising and lowering plate 41, which, by means of lifting elements (lifting and lowering) 42a, 42b, for example controlled pneumatic cylinders, can be raised in the direction of the arrows T. U respectively V, W. and be braked. On the upper surface of the lifting and lowering plate 41 there is a conveyor belt 43 whose belt strands are movable in the direction of the arrows X, Y. The drive and the control of the conveyor belt 43 correspond to this. which has been shown in FIG. 2. During the deposition, the upper strand 43a is moved back and forth under the turntable 2, in the direction of the arrows X, Y. After the deposition of the fiber ruhan in the form of ruhan package 4, on the upper strip strand 43a, the drive motor 15 (see figure 2) is controlled by the control device 6 (see figure 2) in such a way that the upper strip strand 43a takes out the packet tape 4 out of the deposition zone 8 under the turntable 2, and discharges it onto a surface of

support 35.
