Definitions

  • the invention relates to a combing machine with several combing heads, with one the drawing unit assigned to the combing heads, with a sliver laying device, which has a rotating hose wheel above a rotating jug for has the storage of sliver, the single head bands of the combing heads fed close to each other as a fiber ribbon share to the drafting system and there a non-woven tape can be stretched and the non-woven tape using a non-woven funnel near the nip of the output rollers of the drafting system to form a sliver summarized and via guide means the funnel of the tubular wheel are fed.
  • a comber of the type described is known, inter alia, from DE 196 40 855 became known.
  • preferably for combing cotton trained machine will come from the combing heads Single headbands on the so-called table of the comber through guide elements guided, placed side by side and as a sliver share approximately in the Level of the table fed to a drafting system.
  • the exit rollers of the drafting system lead the stretched nonwoven into one Fleece funnel.
  • the guide tube downstream of the fleece funnel is with a Swirl nozzle equipped in the guide tube in the event of insertion of the sliver can briefly generate a spiral air movement. Which the solidifying tip of the sliver passes through the guide tube between the lower guide roller and another calender roller Steig conveyor.
  • This calender roller presses the thin sliver onto the surface of the conveyor belt.
  • the upper guide roller of the ascending conveyor belt is with a large diameter.
  • a curved baffle prevents it in the Area of the upper guide roller by the here at very high speed considerable centrifugal force leads to uncontrollable delays.
  • This The sliver should have the baffle plate with its still firm tip leading into the funnel lead, which is part of a sliver laying device.
  • the funnel are in a manner known per se, calender rolls and one driven below it Assigned hose wheel for the spiral sliver storage.
  • the sliver is a relatively small Roll down into the calender rolls of a sliver laying device belonging hose wheel guided.
  • Such a device is also regarding the quality of the sliver produced highly unsatisfactory.
  • Here is trying to the upcoming Problems caused by regulating the drafting system and the thickness to adjust the sliver as precisely as possible.
  • the operating height of the combing heads is on the feed side of the reel the comb heads at about shoulder height. It’s already extremely difficult there manipulate the wraps with considerable weight at this height.
  • the operating height on the output side of the individual headbands is only at waist height or below.
  • This fiber band share was expected to the maximum, on one slightly upwards inclined plane to be drawn into the drafting system. That way you work at least on the drafting system at normal operating height.
  • the sliver which is quite stable in itself, was regularly cleaned with an ascending conveyor, as described above, brought to the desired height.
  • the object of the present invention is now to provide a comber with several combing heads, with a drafting device and with a sliver laying device, in which the sliver ultimately produced and to be laid down can be conveyed into the can without errors, even at high working speed, and with simple means also the beginning of a sliver can be guided automatically and with high reliability from the drafting device into the nip of the calender rolls of the sliver laying device into the can.
  • the highly sensitive fiber sliver formed after about 20 times warping arises only very close to and above the sliver laying device and can be automatically inserted into the gap of the calender rolls there. It is no longer subject to default due to the now very short path. Control devices with complicated actual value acquisitions and control processes can be reduced to the absolute minimum by this arrangement limit.
  • the conditions are created that the front end of the nonwoven belt passes through at the exit of the drafting system the banding unit is automatically combined, formed into a tip and reliably and without any additional manual work into that Tube wheel can be guided.
  • the fleece tape is swung out Belt forming unit close to the nip of the drafting rollers tore off.
  • the fleece funnel is then brought into the working position, a swirl flow in the guide tube ensures that the nonwoven tape is compressed to the sliver to form a twisted solid band tip and for transporting the tip to between the calender rolls of the sliver laying device.
  • the modification of the drive according to claim 8 allows a correction of the strip thickness to be deposited by changing the angular velocity of the Output roller pair of the drafting system. With this control arrangement you can compensate for up to 70% of all possible differences.
  • the arrangement of the encoder there are only a few on the calender rolls of the sliver laying device Centimeters from the exit rollers of the drafting system, so that the Most of the necessary corrections can be carried out successfully.
  • the design of the cleaning device according to claim 12 ensures a permanent cleaning of the drafting system with simple technical means.
  • the invention is described with the aid of a cotton combing machine a variety of combing heads 1 is equipped.
  • a so-called single headband 9 is produced and in the plane of the table 11
