Definitions

  • the invention relates to a nonwoven guide device for a combing machine according to the preamble of the main claim.
  • the tear-off cylinders form a combing machine fleece from successively fed, combed fiber packets and deliver this onto a fleece guide plate, which leads the fleece to a pair of take-off rollers also mounted in the machine frame.
  • nonwoven guide plates are z.
  • the guide plates are provided with lateral guide surfaces, which serve for the lateral guidance of the fiber fleece.
  • the nonwoven guide plates consist of at least two differently oriented sections. In this case, the execution of the DE 44 45 150 A1 following the tear-off cylinders on a first rising portion, which is followed by a sloping portion, from which the non-woven fabric is delivered to a pair of draw-off rollers.
  • the transport of the fiber fleece above the fleece guide plate is wave-shaped.
  • unclean edge regions of the fiber fleece can arise. This can cause fraying in the edge area, which can lead to problems in the area of the delivery to the downstream take-off rolls.
  • This object is achieved by proposing that the lateral guide walls in the longitudinal section each extend at an angle between 10 ° and 30 ° to the conveying direction of the web and in the region of their end portions, which are arranged immediately in front of the pair of withdrawal rollers, each with a guide element are provided, which projects above and at a distance from the nonwoven guide plate.
  • the guide element is provided with a non-woven guide plate opposite guide surface.
  • the proposed device it is ensured that the edges of the nonwoven fabric are guided clean, especially in the area of the delivery to the take-off rolls and fraying of the non-woven edges is prevented.
  • the proposed guide, or the guide plate opposite guide plate even allows partial solidification of the fleece edges, before the nonwoven fabric is delivered to the Abreisszylinder.
  • This is further supported by a development of the invention by proposing that the distance of the guide surface to the nonwoven guide plate - seen in the conveying direction of the nonwoven - decreases. As a result, it can be achieved in part that the fiber fleece is slightly rolled in the edge regions before it is transferred to the draw-off rolls.
  • the guide surface - viewed transversely to the conveying direction of the nonwoven fabric - is arranged in the direction of the center of the nonwoven guide device with respect to the nonwoven guide plate at an angle rising. This angle can be between 1 ° and 30 °.
  • the guide surface of the guide element is formed in a circular arc, the inner radius of the nonwoven guide plate facing.
  • the Guide surface - viewed transversely to the conveying direction of the nonwoven - has a width between 8 and 20 mm.
  • the nonwoven guide plate has a Abreisszylindercru immediately adjacent first, rising to the conveying direction of the nonwoven fabric section, which issued the Abreisszylindercru nonwoven fabric upwards deflects and is provided at least with a, the first section following and sloping second section for the transfer of the nonwoven fabric to the take-off rolls.
  • a baffle plate (10) may be arranged above and at a distance from the first section (9.1) of the nonwoven guide plate (9). This baffle plate, the z. B.
  • the first section of the fleece guide plate be formed at an angle between 40 ° and 60 ° to the conveying direction of the Abreisszylinderpoves.
  • the longitudinal section of the nonwoven guide plate in which the lateral guide walls extend at an angle to the conveying direction of the nonwoven, is arranged in the second sloping section of the nonwoven guide plate.
  • Fig. 1 shows a schematic vertical section through parts of a combing head of a combing machine.
  • a combing machine has eight combing heads which are arranged next to one another.
  • Fig.1 contains a combing head two pairs of tear-off cylinders 1, 2 and 3, 4 and a pair of withdrawal rollers 5, 6.
  • the tear-off cylinders 1, 2, 3 and 4 and the take-off rollers 5, 6 are rotatable about horizontal axes in a merely schematically indicated machine frame 7 of a combing machine stored.
  • a fleece guide means with a non-woven guide plate 9 for supporting a Abr regardingzylindercru 3, 4 and the withdrawal roller pair 5, 6 running comber V (short fleece or nonwoven fabric called) via a schematically illustrated fastener 14 appropriate.
  • the immediately adjacent to the Abreisszylinderschreib 3, 4 adjacent section 9.1 of the nonwoven guide plate 9 is inclined with respect to the dispensing direction F of the Abreisszylindercrues 3, 4 at an angle ⁇ rising to deflect the issued by Abreisszylinderschreib 3, 4 fleece V upwards.
  • the dispensing direction F is the direction perpendicular to a plane containing the axes of the two tear-off cylinders.
  • the angle ⁇ is in a range between 40 ° and 60 °.
  • "Immediately adjacent" means in this case that the point of impact of the web V on the top of the nonwoven guide plate 9 and the section thereof 9.1 from the nip of the tear-off cylinders 3, 4 should have the smallest possible distance. This distance can be about 2 to 3 cm.
  • a baffle plate 10 is attached at a distance from the section 9.1 of the nonwoven guide plate 9.
  • the baffle plate 10 extends approximately parallel to the surface of the nonwoven guide plate 9 of the section 9.1. However, the parallel alignment is not necessarily necessary for the function.
  • the nonwoven V deflected upward from the section 9.1 is again deflected by the baffle plate 10 in the direction of the take-off roller pair 5, 6.
  • the baffle plate 10 also serves to move the web V (or parts thereof) into the area of the upper Abreisszylinders 4 and a cleaning roller 11, which rests on the upper tear-off cylinders 2, 4, to prevent. This prevents further risk of winding formation.
  • electrically conductive materials for the nonwoven guide plate 9 and the baffle plate 10 the electrostatic charges of the nonwoven are discharged to the machine frame 7 via the likewise electrically conductive attachment means 8. This prevents accumulation of material on the nonwoven guide plate 9 due to electrostatic charges.
  • the web guide plate 9 in its width on both longitudinal sides LS by an angle ⁇ .
  • the angle ⁇ is between 10 ° and 30 °.
  • the nonwoven edges VR of the nonwoven V impinge on the respective guide wall 15 and, in their further forward movement in the conveying direction FR, are displaced toward the middle of the fleece by the further tapering.
  • the nonwoven edges harden, which prevents the disadvantageous fraying described above.
  • the fleece edges then tend to push up along the side walls 15 at least in the end region shortly before delivery to the draw-off rolls 5, 6.
  • This guide element 17 can each consist of a guide surface B, which faces the nonwoven guide plate 9 at a distance a. This is in particular from the section AA of the Fig.1 can be seen which in Fig. 3 in enlarged representation is shown. It can also be seen that the guide surface B with respect to nonwoven guide plate 9 in the direction of the web center M under a winding ⁇ slightly rising. This is to support the Einrollf Anlagen the fleece edges.
  • the width b of the guide element 17 is to be dimensioned accordingly in order to be able to guide the nonwoven edges accordingly.
  • FIG. 4 Another embodiment of guide elements 17a is in the Fig. 4 which also shows an enlarged sectional view AA.
  • the guide surface C is designed in a circular arc with a radius R.
  • the Einrollfmaschine the nonwoven edges VR can be further enhanced.
  • the guide member 17 (17 a) extends at an angle ⁇ with respect to the nonwoven guide plate 9, and to the conveying direction FR, wherein the distance a - seen in the conveying direction FR - reduced.
  • the nonwoven edges VR are compressed even before the transfer, or delivery to the nip of the take-off rolls, whereby the detection of the web V can be done by the take-off rolls 5, 6 in the area of the fleece edges without problems and without material jams.
  • the process of the nonwoven guide following the Abreisszylindertab 3, 4 is carried out in conjunction with the inventively designed nonwoven guide device as follows:
  • the nonwoven fabric V delivered stepwise by the tear-off cylinder pair 3, 4 strikes the first section 9.1 of the nonwoven guide plate 9 and is deflected there in the direction of the baffle plate 10. From the baffle plate 10, the web V is further deflected to the second section 9.2 of the nonwoven guide plate, to which it is further transported in the conveying direction FR to the.
  • the nonwoven Before the nonwoven, however, enters the nip line of the take-off rolls 5, 6, it meets with its fleece edges VR on the lateral guide walls 15 of the tapered longitudinal section LA of the nonwoven guide plate 9. Upon further forward movement, the nonwoven edges VR of the nonwoven are compacted by the taper and partially the Edge fibers rolled up. By in the conveying direction FR reduction of the distance a between the nonwoven guide plate 9 and the guide surface B, and C of the guide member 17, or 17a is carried out a further compression of the web edges VR before the web to the nip of Take-off rollers 5, 6 is discharged.
  • the fleece arrives at a table T, which is fed via a beveled trigger to a take-off hole, which are not shown downstream take-off rollers, which are delivered there comber machine belt formed on another table on which it with other bands a subsequent drafting be supplied.
  • a take-off hole which are not shown downstream take-off rollers, which are delivered there comber machine belt formed on another table on which it with other bands a subsequent drafting be supplied.
