Consequently the flat bars always come onto the sliding guide and perform repeatedly Carding with the drum.
  • lid heads which Have sliding surfaces on the respective sliding guides on both sides of the Slip card. These sliding surfaces determine with the sliding surfaces of the sliding guides the distance between the tips of the cover sets and the tips of the Drum sets. This distance must be in the manufacture of the card and at The card's re-yarning can be adjusted precisely, taking one nowadays Carding distances, i.e. Clearances between the tips of the lid sets and the Aim for a drum set in the range of about 0.2 mm. Only then is a high quality Carding work possible with high card production.

  • This latter possibility has the great advantage that the card is not stopped for grinding the drum and cover sets must be so that the production is not affected. Beyond that ensures that the trimmings always have optimal sharpness and thus always produces a card sliver with uniform and high-quality properties becomes what benefits the subsequent yarn production.

  • DE 29 48 825 A1 is also related to the adjustment of the flex arches a card of great interest. There it is recognized that the carding distance may change in operation, both due to strains caused by Centrifugal forces are caused as well as due to thermal expansion, which occurs at Warm up or cool down the card.

Both the influence of centrifugal force and the Influence of the temperature rise do not have an immediate effect when the Machine off, but only after a certain time delay, which is what the Influence of centrifugal force affects at least as long as the acceleration time of the involved elements, e.g. of the drum, is.
  • DE-A 29 48 825 describes a control method of the employment relationships between two people who are equipped with a high-end set Working elements, such as the drum and the traveling cover one Revolving flat card, described in which one with the dimensions of the drum in a directly related variable is recorded continuously or over time and the carding distance by a suitable control depending on the recorded size is kept at a certain value.

  • radial displacement of the supports 959 in accordance with the Double arrow 981 while heating the sliding guide 952 can this Accept the desired radial position.
  • the middle support 959 ' only serves here the determination of the starting position of the sliding guide 952, but is also displaceable according to the double arrow 981.
  • Each part 952 can, if desired, be formed as an elongated bimetal strip which results in a pronounced bend at lower temperatures of the sliding guides is achievable.
  • the parts forming the slide guides 952 can each are formed as a continuous double wedge, as shown in FIG. 14 at 952 ', i.e. so that the sliding guide has a greater radial depth in the central longitudinal region has than in the respective end regions distant from each other. This training ensures that the sliding guides when bending due to the generation of heat Experience uniform radial adjustment over its entire length.
  • the parts forming the sliding guides can each have a constant radial dimension over their entire length, as shown at 652 in FIG. 10.
