  • a balloon limiter pot 7 is fastened, in the wall of which a thread guide channel 8 is guided vertically upwards, with its lower end to the thread guide channel 6 connects and from its upper end the thread F3 is guided to the centering eye 9.
  • the spindle rotor consists essentially of the following Elements: hollow shaft 3, spindle rotor disc 5, balloon limiter pot 7 with thread guide channel 8 and thread guide tube 10.
  • the hollow shaft 3 On the upper end of the hollow shaft 3 is an essentially by means of suitable bearings closed inner housing 12 mounted, for example by means of not shown Permanent magnet is secured against rotation and a bottom 12.1, one Has cylinder housing 12.2 and a cover 12.3.
  • inner housing 12 In the inner housing 12 are two rotor spinning devices or OE spinning units R1 and R2 housed, whose spinning rotors 13, 14 are open at the top and by means of a drive belt 15 are driven by a motor, not shown.
  • the energy supply this drive motor takes place through the spindle rotor disk 5 through a schematic indicated system of slip ring contacts 16, 17 with adjoining them electrical cables.
  • the spindle rotor is surrounded by an outer housing 18, consisting of a bottom 18.1, a lower cylinder housing section 18.2, an upper cylinder housing section 18.3 and a removable cover 18.4, which has the centering eye 9.
  • the spinning rotor 14 opens a fiber material feed channel that an inner through the cover 12.3 channel section 19.1 and one through the has upper channel housing section 18.3 guided channel section 19.2.
  • the Spinning rotor 13 has the same fiber material feed system, not shown in detail on.
  • Thread take-off tube 20 In connection with the spinning rotor 13 is representative of both spinning rotors Thread take-off tube 20 shown. Through the thread take-off tubes 20 in the Spinning rotors 13, 14 produced spun threads F1 and F2 are drawn off and over pulleys 26, 27 passed before going down through the top inlet end directional spindle hollow axis 21 enter, with the interposition of an annular gap seal 22 opens into the upper end of the thread guide tube 10.
  • the piecing device 30 described below with reference to FIGS. 2 to 4 is housed in a recess 12.3 'on the top of the cover 12.3.
  • this piecing device 30 consists of an essentially rotationally symmetrical one Base body 31, the bottom 32 with a central, coaxial to Spindle hollow axis 21 lying opening 33 and with side openings 34, 35, the each connect to the spinning thread draw-off tubes 20 of the spinning rotors 13, 14.
  • a support plate 55 is mounted on the next the pulleys 26, 27 already discussed above, two delivery plants and as Thread storage elements two clamping devices as essential parts of the invention Piecing device 30 are mounted or attached.
  • the clamping device consists of an essentially ridge-like block 56, whose two inclined surfaces form clamping surfaces 36 and 37, respectively. Every clamping surface is a movably mounted clamping plate 38 and 39 assigned, the magnetic Material. Each clamping plate 38 and 39 is floating and is provided a rearward-facing approach 38.1 and 39.1, respectively Distance from each other ends of the approaches at the transition points to the actual clamping plate 38 incisions 38.2 and 39.2 are attached.
  • To the Block 56 is a plate 41 fastened with a screw 42.
  • the plate 41 has accordingly the "ridge surface" of the ridge-like block 56 has the shape of an isosceles Triangle, the legs of which are parallel to the inclined clamping surfaces 36 or 37.
  • a permanent magnet 40 is inserted in such a way that the single clamping plate 38 under the influence of magnetic force either in the clamping position pulled against the stationary clamping surface or by interaction between their rear attachment 38.1 or 39.1 and the permanent magnet 40 in the open position is held.
  • the individual clamping plate 38 or 39 is thus between Clamping and opening positions can be swiveled.
  • Each of the two delivery plants has two rollers 51, 52 and 53, 54, each of which one roll can be swung away from the other roll, as it is for the Roll 52 is illustrated with the aid of the roll 52 'shown in dashed lines.
  • the two Rolls 51, 52 and 53, 54 of each delivery unit are arranged so that each roll gap directly to the lower end of the two cooperating clamping surfaces each Storage element connects.
  • the pivotably mounted roller 52 or 54 of each delivery mechanism is preferred spring-loaded, so that this pivotable roller can be adjusted resiliently against its counter roller is.
  • the roller 51 is designed as a hollow body, with its inner wall on a spherical support body 46 fastened on an axis 45, preferably in Spherical shape, is supported. Bearing against the outer peripheral surface of the roller 51 the opposite ends of the roller 51 stop body 47, 48 parallel to the plane defined by the axes of the two rollers 51, 52 on the one hand and perpendicular are aligned with the roller gap of the supplying plant.
  • roller 51 change its position only about a vertical axis in one plane can, which is determined by the axes of the two roles, while by the pivoting against the top of the roller 51 abutment body 47, 48 or tilting of the roller 51 prevented about a horizontal axis in one plane becomes tangent to the lateral surfaces touching in the area of the roller gap of the two rollers 51, 52 is placed.
  • the take-up spool becomes a thread from above through the centering eyelet 9 of this cover 18.4 and then through the thread guide channel 8, the radial thread guide channel 6, the thread guide tube 10 and the spindle hollow axis 21 are threaded through.
  • the one out the upper end of the thread guide tube 21 emerging thread is at one Gripped point where preferably a completely intact twist of the thread is available. Then the twist is turned back over a certain length of thread, whereby the originally present in the not yet twisted filaments Spin turns back into the individual threads.
  • each individual "fixed” spider thread is then in the form of a loop FS with two parallel thread branches on the stationary clamping surface 36 or 37 stored and by means of the movable clamping plate 38 or 39 in clamped in this loop-shaped form. Because of the floating Storage of the movable clamping plate 38 and 39 is under the influence of the permanent magnet 40 ensures that even with differences in thickness of the loop pinched thread section an optimal, even clamping of both Loop branches are present.
  • the free end of the spun thread is allocated through the thread draw-off tube 20 Spinning rotor introduced, so far that it is before the start of the fiber material feed in the rotating spinning rotor still inside the spinning rotor hollow axis or the spinning rotor discharge tube is such that it is with the spinning rotor rotating is not yet exposed to centrifugal force.
  • a reversal of the spinning twist is thus only possible in the relatively short spun thread section between the roller gap of the individual delivery mechanism and the thread end inserted into the individual spinning rotor.
  • the spinning rotation generated by the OE spinning rotor also runs into the previously free end of the spinning thread, so that immediately after spinning there are two spinning threads which have the spinning twist required for the double-wire twisting process.
