Definitions

  • the technical field of the invention is textile machines. Is in this area particularly affected a route that has a calendering facility that mostly consists of two opposing calender rolls or calender discs, with which the sliver is compressed.
  • the invention is concerned with Sliver guide and the guide nozzles that define this guide.
  • a pair of delivery rollers to be arranged at the exit of a drafting system of a draw frame (as an example of a sliver processing machine), which conveys nonwoven into a fleece funnel.
  • the fiber sliver is spread out in accordance with the roller width due to the distortion.
  • the person skilled in the art describes the fiber sliver that is spread out at this point as a non-woven fabric.
  • the non-woven fabric ie the spread fiber sliver is conveyed into the opening of a non-woven funnel.
  • the fleece funnel the fiber fleece is rolled up and combined and transported further through the funnel mouth to a sliver tube which has a considerable length.
  • the sliver is introduced into a sliver funnel, which deflects the conveying direction of the sliver by approximately 90 ° and introduces it between a pair of calender rolls. After passing through the pair of calenders, the sliver compacted there is conveyed on to the laying device of the draw frame.
  • a sliver funnel which deflects the conveying direction of the sliver by approximately 90 ° and introduces it between a pair of calender rolls.
  • the sliver compacted there is conveyed on to the laying device of the draw frame.
  • the sliver tube being designated 8 and the delivery rollers of the draw frame 70b and 70a.
  • a structure with a long sliver tube 8 is also described in EP 593 884 A1 .
  • Another example of a long sliver tube (also designated 8 there) is US 4,372,010 ; the pair of calender rolls is designated 9a, 9b there.
  • Another example of the custom of the long sliver tube is shown in DE-A 26 23 400 .
  • the sliver tube itself is curved at an angle of approximately 90 ° and guides the sliver without changing the angle between the calender disks designated 5, 6 there. It is described as advantageous if the tube denoted by 14 is flattened in an oval shape (see page 9, last paragraph).
  • the DD 290 697 also shows a collector pipe .
  • the fleece funnel and belt funnel are clearly spaced there.
  • a ventilation opening (there 8) allows the air flowing in at the beginning of the collecting pipe (there 5) to escape completely in front of the narrowest point of the band funnel.
  • DE 36 12 133 A1 (FR 2 597 119 A1) relates to a belt guide channel between exit rolls and calender rolls on a spinning preparation machine.
  • the tape guide channel concerns the automatic insertion of a tape start into a tape funnel (there column 4, 45th to 55th row).
  • the tape guide channel is relatively long and has a large diameter.
  • the belt guide channel gives the sliver the necessary guidance on the way to the belt funnel. In this way, several injectors (there air duct 5, compressed air line 8) are arranged at different locations in the band guide duct. The entire volume of the belt that is fed at the beginning of the belt must then be compressed exclusively in the belt funnel (column 2, lines 61 to 63).
  • the band hopper must have a device for temporarily increasing its cross section. This is a prerequisite for automatic insertion of the sliver.
  • a further disadvantage is that the calender rollers must also be opened for the automatic introduction of the strip start. The beginning of the belt cannot be drawn into the clamping gap of the calender rolls when the closed calender rolls rotate.
  • the mouth of the band funnel (6, 6 ', 6 ") there is asymmetrical, ie the mouth region of the band funnel in the vicinity of the movable calender roll 2 is set back considerably more than with the other calender roll 3. As the cause is to be concluded that the sliver striking should support the opening movement of the calender roll 2.

  • the arrangement of the pivot axis makes it possible for the dynamic pressure of the supplied fleece when it can no longer be removed, the Fleece funnel automatically swiveled out of its operational position swivel a ramp of the fleece funnel in the operational conveying direction, wherein the ramp has such an inclination in the pivoted position that the fleece that strikes them (initially promoted further) perpendicular to the normal one Direction of transport is deflected out of the interior of the drafting system.
  • the arrangement of the pivot axis results in a very small lever arm, to which the fleece fed into the fleece hopper acts in order to apply only slight forces need to swivel the fleece funnel. It works particularly easily Fleece funnel in the event of a fleece jam if the pivoting axis is below the Fleece funnel lies and the break point K lies in the pivot axis.
  • the fleece funnel can be designed to be removable in all of its operational positions, but in particular in the pivoting position, which corresponds to both the processing position for threading the fleece and the fleece stowage position.
  • the processing position or fleece stowage position can be buffered in order to achieve a gentle stop with automatic pivoting.
  • the interchangeable stop is buffered to achieve a gentle stop when the fleece funnel is pivoted automatically.
  • the buffered pivotability can also be used manually to carry out maintenance or cleaning work.
  • a corresponding gripping and actuating section is attached to the swiveling fleece funnel in an easily accessible manner.
  • the swiveling fleece funnel has a funnel area and one next to it arranged ramps so that the nonwoven fabric in the operating position of the Fleece funnel by rolling, deflecting and merging to form the sliver is formed and when the fleece funnel is tilted the ramp ensures that this is on it too-promoted nonwoven fabric is deflected so that it is out of the deflection area is conveyed out, the drafting area is not blocked and easily by the operator can be removed.
  • the ramp also ensures that no fleece jam can form because of the Fleece funnel then automatically by the force of the nonwoven conveyed on it pivots and the ramp continues the conveyed nonwoven fabric until it is switched off guides the delivery rollers out of the drafting system interior.
  • the fleece funnel has immediately took up his work position, which corresponds to the position, which it accepts when fleece jams occur.
