Definitions

  • the invention relates to all-steel fittings for rollers and / or drums of cleaners, cards or carding machines, which rollers or drums have a higher peripheral speed than upstream rollers in the fiber flow direction, the all-steel clothing having teeth with a positive breast angle of> 0 °.
  • the rolls concerned here are, for example, licker-in rolls, turning rolls or transfer rolls on cards or cards, and the drum of a card or card. These rollers or drums take over fiber raw material actively with the front edge of the breast angle of the teeth of the corresponding all-steel clothing.
  • the object of the invention is to provide an all-steel fitting of the type mentioned at the outset, which eliminates the disadvantages observed in the prior art while maintaining good transfer properties.
  • the teeth have a head angle which is> 85 °, preferably> 87 °, the length of the head surface extending at this angle from the tooth tip to the back of the tooth being at least 15%. corresponds to the length of the tooth pitch.
  • the head angle of the tooth is 90 °. This means that even after grinding the clothing, the same conditions are present on all teeth, which in turn leads to an improvement in the carding quality.
  • the length of the head surface corresponds to at least 25% of the tooth pitch.
  • the length of the head surface corresponds to at least three times, preferably five times its width.
  • the length of the head surface is greater than or equal to half the tooth height, measured from the tooth base to the tooth tip. This creates a relatively low set, which surprisingly leads to good carding ratios. It is particularly preferred if the length of the head surface corresponds to the tooth height.
  • the tooth back adjoining the top surface encloses an angle between 20 and 30 °, preferably 25 °, with the following tooth face.
  • This opening angle between the back of the tooth and the tooth face tends to be smaller than in the prior art sets; however, it is sufficient to ensure problem-free transfer of the fibers from the upstream roller.
  • the all-steel clothing described above is particularly suitable for reels of cotton cards, so-called high-performance cards, with a drum circumferential speed of more than 1500 m / min as well as an all-steel drum clothing with a total height of less than 3 mm and a foot width of less than 0.7 mm. Protection is therefore claimed separately for such a cotton card equipped with an all-steel clothing according to the invention. Exemplary embodiments of the invention are explained in more detail below with reference to a drawing.
  • FIG. 1 is a schematic representation of a card in a side view
  • Fig. 2 shows the tooth geometry of an all-steel fitting.
  • FIG. 3 shows a sectional view of the illustration from FIG. 2 along the line III-III
  • Fig. 4 shows the geometry of an all-steel fitting.
  • FIG. 5 shows a sectional view along the line V-V from FIG. 4.
  • Fig. 1 shows a schematic representation of a card with a drum 1, feed rollers 2, a licker-in 3 and turning rollers 4. The circumferential direction of rotation of the rollers is shown in FIG. 1 by arrows.
  • the clothing described in the following relates to such rollers or drums that actively take over fibers from the upstream rollers.
  • Examples are the licker-in 3, the turning rollers 4 and in particular the drum 1 in the illustration shown in FIG. 1.
  • Fig. 2 now shows in sections a saw tooth wire of an all-steel set, as is provided for the drum shown in Fig. 1. It is a sawtooth wire with a total height of 2mm and a tooth pitch, measured from tooth tip 5 to the next 5 'of 1.7mm.
  • the breast angle ⁇ of the tooth face 6 measured in relation to the vertical is 40 ° in the exemplary embodiment shown here.
  • the tooth back 7 does not directly adjoin the tooth tip; rather, a head surface 8 is initially provided.
  • the angle of the head surface ⁇ again measured with respect to the vertical, is 87 ° in the exemplary embodiment shown in FIG. 2.
  • the length L of the head surface 8 is 0.5 mm, its width B (see FIG. 3) is 0.07 mm.
  • the tooth height H, measured from the tooth base to the tooth tip 5, is slightly less than 0.5 mm.
  • the angle y enclosed by the tooth face 6 and the tooth back 7 is 24 ° in the exemplary embodiment shown here.
  • the distance from the tooth tip 5 to the adjacent tooth tip 5 ' is only 1.5 mm.
  • the breast angle ⁇ is only 30 °.
  • the angle y enclosed between tooth face 6 and tooth back 7 is 25 ° in this exemplary embodiment.
  • the two exemplary embodiments do not differ fundamentally.
  • the sawtooth wire shown in Fig. 2 has a larger chest angle, which is fundamentally favorable for a more active fiber takeover.
  • What is decisive for both variants, however, is that with a relatively low tooth height, a long head surface is provided which is almost not inclined and which therefore gives the tooth tip and the entire set increased stability.
  • the tooth geometry does not change practically even after grinding the set, so that on the one hand practically the same conditions are present and on the other hand the carding quality does not change even after grinding the sets.
  • the sets are pulled up in a conventional manner.
